🌉 Token2049 Infrastructure Panel: The Multichain Future is Here (And It's Messy)

Just left the “Multichain Infrastructure” panel at Token2049 and I need to vent.

Everyone talks about “the multichain future” like it’s this beautiful, seamless thing.

Reality: It’s a MESS. And we’re all scrambling to make it work.

As infrastructure engineer, let me share the brutal truth about building in a multichain world.

The Panel: “Interoperability in 2025”

Speakers:

  • CTO of major RPC provider (supports 95+ blockchains)
  • Founder of cross-chain bridge protocol
  • Developer relations lead from L1 blockchain
  • Researcher from interoperability protocol
  • Me: Infrastructure engineer (suffering from multichain fatigue)

Opening question: “Is multichain the future, or will one chain rule them all?”

Unanimous answer: “Multichain is here. It’s not the future, it’s the present. And it’s chaos.”

The Numbers: How Many Chains Are There?

RPC provider shared their data:

Blockchains they support: 95+

Breakdown:

  • EVM chains: 60+ (Ethereum, L2s, Polygon, BSC, Avalanche, etc.)
  • Non-EVM L1s: 20+ (Solana, Cosmos chains, Polkadot parachains, etc.)
  • App-chains: 15+ (dYdX chain, Sei, etc.)

And this is just the major ones. Total chains in existence: 200+

Panel quote (RPC provider CTO): “We add a new chain to our platform every 2-3 weeks. It never stops.”

My reaction: This is insane. How did we get here?

How We Got to 95+ Chains

The evolution:

2015-2017: Ethereum maximalism

  • One chain to rule them all
  • “We’ll scale Ethereum, don’t need other chains”
  • Reality: Didn’t scale

2018-2020: Alt-L1 wars

  • EOS, Tron, NEO, etc. challenging Ethereum
  • “We’re faster/cheaper than Ethereum”
  • Reality: Most died or became zombies

2021-2022: L2 explosion

  • Ethereum too expensive ($50-100 gas fees)
  • L2s emerge: Arbitrum, Optimism, etc.
  • “We’ll scale Ethereum with L2s”
  • Reality: Fragmented liquidity

2023-2024: App-chain era

  • dYdX launches own chain
  • Cosmos/Polkadot app-chain thesis proven
  • “Every major dApp gets own chain”
  • Reality: Even MORE fragmentation

2025: Multichain reality

  • 95+ significant chains
  • Liquidity spread thin
  • Users confused
  • Developers exhausted

We didn’t choose multichain. We stumbled into it.

The Developer Pain: Managing 95+ Chains

Panel discussion on developer experience.

DevRel lead: “We support 15 chains. Every chain is slightly different. It’s exhausting.”

What’s different across chains:

Difference 1: Block Times

Examples:

  • Ethereum: 12 seconds
  • Arbitrum/Optimism: 2 seconds
  • Polygon: 2 seconds
  • Solana: 400 milliseconds
  • Cosmos chains: 1-7 seconds (varies)

Why this matters:

  • Time-based logic breaks across chains
  • “Wait 10 blocks” means different things on each chain
  • Need to code for each chain’s block time

Pain level: 3/10 (annoying but manageable)

Difference 2: Gas Mechanisms

Ethereum (EIP-1559):

  • Base fee + priority fee
  • Base fee burns ETH
  • Priority fee to validators

BSC (BNB Chain):

  • Simple gas price auction
  • No burning mechanism

Solana:

  • Compute units (different model)
  • Priority fees optional

Avalanche:

  • Dynamic fees
  • Different on C-Chain vs subnets

Why this matters:

  • Gas estimation logic differs per chain
  • Can’t reuse gas optimization techniques
  • Need chain-specific gas strategies

Pain level: 6/10 (requires significant code changes)

Difference 3: Account Models

Ethereum/EVM:

  • Account-based (addresses have balances)
  • Smart contracts are accounts

Solana:

  • Account model (but different)
  • Accounts own data, programs are stateless
  • Rent mechanism (pay to keep data alive)

Cosmos chains:

  • Account-based (similar to Ethereum)
  • But different address formats (bech32)

Bitcoin/UTXO chains:

  • UTXO model (completely different)
  • No smart contracts (or limited via scripts)

Why this matters:

  • Core programming model differs
  • Can’t port Ethereum contracts to Solana easily
  • Need to rewrite from scratch for non-EVM chains

Pain level: 9/10 (architectural differences, massive work)

Difference 4: Consensus Mechanisms

Ethereum: Proof of Stake (Gasper)
Solana: Proof of History + Proof of Stake
Polygon: Modified PoS
Arbitrum/Optimism: Inherit Ethereum consensus (but have sequencers)
Cosmos chains: Tendermint BFT (or CometBFT now)

Why this matters:

  • Finality times differ (instant to 7+ days)
  • Reorganization risk varies
  • Need different confirmation requirements

Pain level: 5/10 (mostly impacts UX, not core logic)

Difference 5: Smart Contract Languages

Ethereum: Solidity, Vyper
Solana: Rust (via Anchor framework)
Cosmos: Go (CosmWasm for smart contracts)
Polkadot: Rust (ink!)
Move chains (Aptos, Sui): Move language

Why this matters:

  • Can’t reuse contracts across ecosystems
  • Need different developer skillsets
  • Hiring is harder

Pain level: 10/10 (complete rewrites, different paradigms)

The Infrastructure Challenge: Supporting 95+ Chains

RPC provider CTO broke down their infrastructure:

Per-chain requirements:

For each chain, they need:

  • Full nodes (to serve RPC requests)
  • Archive nodes (for historical data)
  • Indexers (to index transactions, events)
  • Monitoring (to detect issues)
  • Updates (when chain upgrades)

Cost per chain:

  • Small chain: $2K-5K/month
  • Medium chain: $10K-30K/month
  • Large chain (Ethereum): $100K+/month

For 95 chains:

  • Average: $15K/month per chain
  • Total: $1.4M/month in infrastructure costs

Revenue needed to break even: $1.4M+/month from customers

This is why only large RPC providers survive.

Panel quote (RPC CTO): “We’re infrastructure company with profit margins of traditional tech. This is not crypto-native margin.”

Small providers can’t compete. Consolidation inevitable.

The User Pain: Which Chain Should I Use?

Researcher perspective on user confusion:

User journey:

  • Wants to swap tokens on Uniswap
  • Uniswap available on: Ethereum, Arbitrum, Optimism, Base, Polygon, BSC
  • Which one to choose?

Factors to consider:

  • Gas costs (varies 100x: $0.10 to $10)
  • Liquidity (Ethereum > Arbitrum > others)
  • Security (L2s inherit Ethereum security, sidechains don’t)
  • Speed (2-second blocks vs 12-second)
  • Token availability (some tokens only on certain chains)

User reaction: “I just want to swap. Why is this so complicated?”

Panel consensus: “Users shouldn’t need to know about chains. But currently, they do.”

This is a UX disaster.

The Liquidity Fragmentation Problem

Bridge protocol founder shared their data:

Uniswap liquidity distribution (example):

  • Ethereum L1: $3B
  • Arbitrum: $1B
  • Optimism: $500M
  • Base: $300M
  • Polygon: $800M
  • BSC: $400M
  • Total: $6B spread across 6 chains

Problem:

  • User on Arbitrum wants to swap $10M
  • Arbitrum liquidity: $1B (1% of trade would be slippage)
  • Ethereum L1 liquidity: $3B (0.3% slippage)
  • User forced to bridge to L1 (costs $20-50, takes 7 days)

Multichain fragmented the liquidity.

Panel quote: “We’re less capital efficient than if everything was on one chain.”

This is the core multichain problem.

Current Solutions (And Why They’re Inadequate)

Solution 1: Cross-Chain Bridges

How they work:

  • Lock tokens on Chain A
  • Mint wrapped tokens on Chain B
  • When bridging back, burn on B, unlock on A

Major bridges:

  • Across Protocol
  • Connext
  • LayerZero-based bridges
  • Chainlink CCIP

Problems:

Problem A: Security risk

  • $2B+ stolen from bridge hacks (2021-2022)
  • Single point of failure
  • If bridge is compromised, funds lost

Problem B: Liquidity requirements

  • Bridges need liquidity pools on both chains
  • Capital intensive

Problem C: Time/cost

  • Optimistic bridges: 7+ days to withdraw
  • Fast bridges: $5-20 in fees
  • Users want instant + cheap (can’t have both)

Panel discussion got heated:

Bridge founder: “We’re making it better. New bridges are more secure.”
RPC CTO: “Sure, but we’ve said that after every bridge hack. Then another hack happens.”

Uncomfortable truth: Bridges are weakest link in multichain.

Solution 2: Cross-Chain Messaging

Protocols like LayerZero, Chainlink CCIP:

How they work:

  • Send message from Chain A to Chain B
  • Message contains instructions (not just token transfers)
  • Can trigger smart contract calls on destination chain

Use cases:

  • Cross-chain governance (vote on one chain, execute on another)
  • Cross-chain lending (collateral on Chain A, borrow on Chain B)
  • Omnichain NFTs (NFT exists on multiple chains)

Benefits:

  • More flexible than simple bridges
  • Enables complex cross-chain dApps

Problems:

  • Complex to build with
  • Security still relies on messaging protocol
  • Adds latency (messages take time to relay)

Current state: Early. Few dApps using this. Experimental.

Solution 3: Chain Abstraction

The dream: Users don’t see chains. Everything “just works.”

How it would work:

  • User has funds on Arbitrum
  • Wants to use dApp on Optimism
  • Protocol automatically bridges funds
  • User never knows it happened
  • Seamless UX

Who’s building:

  • NEAR Protocol (chain signatures)
  • Particle Network
  • Various account abstraction protocols

Current state: Vaporware. Sounds great, doesn’t exist in production.

Panel quote (researcher): “Chain abstraction is 2-3 years away. Maybe longer.”

Solution 4: Just Use One Chain

The pragmatic approach:

Ethereum L2s (Arbitrum, Optimism, Base):

  • 10x cheaper than L1
  • Same security (inherit from Ethereum)
  • Most DeFi protocols deploy here

Why not just pick one L2 and stick with it?

Answer from panel:

  • Network effects favor multiple chains
  • Different L2s have different backers (Coinbase → Base, Optimism → Optimism Collective)
  • Users already spread across chains (can’t force migration)
  • First-mover advantage (projects launch where users are)

So we’re stuck with multichain.

The Data: Which Chains Actually Matter?

RPC provider shared their traffic data (anonymized):

RPC requests by chain (monthly):

  1. Ethereum: 40%
  2. Arbitrum: 15%
  3. Polygon: 12%
  4. BSC: 10%
  5. Optimism: 8%
  6. Base: 6%
  7. Solana: 4%
  8. Other 88 chains: 5% combined

Top 7 chains = 95% of traffic

Remaining 88 chains = 5% of traffic

Conclusion: Long tail of chains is mostly irrelevant.

Panel discussion:

RPC CTO: “We support 95 chains, but make money on 10 chains. The rest are for completeness.”

Bridge founder: “Most bridges fail because they support too many chains. Focus on chains that matter.”

My take: The market is consolidating around 5-10 dominant chains.

The Cosmos IBC Vision vs Reality

Researcher explained Cosmos’s approach:

Cosmos thesis:

  • Each dApp gets own chain (app-chain)
  • Chains connect via IBC (Inter-Blockchain Communication)
  • Shared security via Cosmos Hub

Examples:

  • Osmosis (DEX)
  • Injective (derivatives)
  • Celestia (data availability)
  • 50+ other Cosmos chains

The vision: Seamless interoperability between app-chains.

The reality:

IBC works well… within Cosmos.

  • Cosmos chains can communicate easily
  • Token transfers are fast (<10 seconds)
  • Shared security works

But: Cosmos ecosystem is isolated.

  • Hard to bridge to Ethereum
  • Users on Ethereum don’t know about Cosmos chains
  • Liquidity fragmented from main DeFi

Panel quote (researcher): “Cosmos solved interoperability within its ecosystem. But that’s not where most users are.”

Result: Cosmos is multichain done right, but it’s a small multichain island.

The Polkadot Parachain Model

Similar to Cosmos but different:

Polkadot thesis:

  • Chains lease slots on Polkadot relay chain (parachains)
  • Shared security from relay chain
  • XCM for cross-chain communication

Advantages:

  • True shared security (better than Cosmos)
  • Good interoperability between parachains

Challenges:

  • Parachain slots are expensive (need to win auction)
  • Limited slots (50-100 parachains max)
  • Complex to build parachains

Current state:

  • 40+ parachains live
  • Some activity but much less than Ethereum ecosystem

Same problem as Cosmos: Isolated from where users are.

What I’ve Learned Building Multichain Infrastructure

I maintain infrastructure for DeFi protocol on 5 chains (Ethereum, Arbitrum, Optimism, Base, Polygon).

Here’s what it takes:

Task 1: Deploy Contracts to 5 Chains

Naive approach: Copy-paste deployment script 5 times

Reality:

  • Chain-specific addresses (oracles, routers, etc.)
  • Different gas estimation per chain
  • Different block explorers for verification
  • Different multisigs for admin functions

Time: 2 days (if nothing goes wrong)

Task 2: Monitor 5 Chains

Need to watch:

  • Transaction volume (is chain working?)
  • Gas prices (should we optimize?)
  • Contract state (any anomalies?)
  • User complaints (per-chain issues)

Tools:

  • 5 different block explorers
  • Tenderly for all chains
  • Custom monitoring scripts
  • Pager alerts (wake up at 3am if issue)

Cost: $5K/month in monitoring tools + engineering time

Task 3: Maintain 5 RPC Endpoints

Can’t use free RPC:

  • Rate limits too low
  • Reliability not good enough
  • Need archive node access

So we pay:

  • Alchemy: $10K/month (Ethereum + Arbitrum + Optimism)
  • QuickNode: $5K/month (Base + Polygon)

Total: $15K/month just for RPC access

Task 4: Bridge Liquidity Between Chains

Problem: We have protocol liquidity on all 5 chains, but fragmented.

Solution attempts:

Attempt 1: Let market handle it

  • Hope arbitrageurs balance liquidity
  • Result: Didn’t work, some chains always dry

Attempt 2: Manual rebalancing

  • Team bridges tokens between chains weekly
  • Result: Slow, expensive ($500+ in bridge fees per week)

Attempt 3: Automated rebalancing

  • Smart contract monitors liquidity, automatically bridges
  • Result: Works but expensive (gas + bridge fees)

No perfect solution.

Task 5: Handle User Support for 5 Chains

User: “Transaction stuck!”
Me: “Which chain?”
User: “Uh… the blockchain?”
Me: “:expressionless_face:”

Teaching users about chains is exhausting.

My Honest Take: Multichain Sucks (But We’re Stuck With It)

What I wish existed:

  • One chain to rule them all
  • Infinite scalability
  • Zero gas fees
  • Perfect security

Reality:

  • 95+ chains
  • Each with trade-offs
  • Fragmented liquidity
  • Terrible UX

But we can’t go back to single chain:

  • Ethereum L1 is too expensive
  • Alt-L1s have different backers/ecosystems
  • Users already spread across chains
  • Network effects lock us in

We’re stuck with multichain. So let’s make it better.

What Needs to Be Built (Priorities)

Priority 1: Better bridges (secure, fast, cheap)

  • Current bridges are 2 of 3 at best
  • Need all 3: Secure AND fast AND cheap

Priority 2: Unified RPC infrastructure

  • One endpoint that routes to all chains
  • Developers shouldn’t manage 95 RPC endpoints

Priority 3: Chain abstraction

  • Users shouldn’t see chains
  • “Use this dApp” not “Use this dApp on Arbitrum”

Priority 4: Liquidity aggregation

  • Single liquidity pool spanning multiple chains
  • Or efficient routing between chain-specific pools

Priority 5: Better dev tools

  • Deploy to 10 chains with one command
  • Test on all chains simultaneously
  • Monitor all chains from one dashboard

These are being built. But not ready yet.

My Take After Token2049

Multichain is here. It’s messy. It’s expensive. It’s confusing.

But: This is reality for next 3-5 years minimum.

So we need to:

  1. Build better infrastructure (bridges, RPC, tooling)
  2. Abstract complexity from users (chain abstraction)
  3. Consolidate around 5-10 major chains (not 95)

The panel convinced me: Multichain won’t go away. We need to make it work.

Because if we don’t, users will give up on crypto entirely.

@blockchain_brian Your pain is my pain. Multichain development is a NIGHTMARE.

Let me answer your question: No, multichain is NOT worth the pain. But we have no choice.

My Multichain Development Journey

2021: Single chain (Ethereum L1)

  • Write contracts
  • Deploy to Ethereum
  • Done

Simple. Expensive for users ($50+ gas), but simple for me.

2023: “Let’s go multichain!”

  • Users demand cheaper gas
  • Deploy to Arbitrum
  • “Easy, just deploy again”

Narrator: It was not easy.

The 5 Stages of Multichain Developer Grief

Stage 1: Denial

“It’s just deploying the same contracts to another chain. How hard can it be?”

Reality check after 1 week:

  • Different gas estimation (Arbitrum uses L1 data cost)
  • Different oracle addresses (need Chainlink on each chain)
  • Different admin multisig addresses
  • Block explorer verification fails (different API)
  • Frontend breaks (hardcoded Ethereum addresses)

Time wasted: 40 hours debugging “simple” deployment

Stage 2: Anger

“Why is every chain SLIGHTLY DIFFERENT?!”

Arbitrum:

  • Uses different gas calculation (L1 data cost + L2 execution)
  • Has special precompiles (ArbSys contract)
  • Sequencer can reorder transactions

Optimism:

  • Similar to Arbitrum but different L1 data cost formula
  • Different address for L2 cross-domain messenger
  • 7-day withdrawal period

Base:

  • Basically Optimism but Coinbase-run
  • Different sequencer address
  • Need to use Base-specific RPCs

Polygon:

  • Sidechain not L2 (less secure)
  • Uses MATIC for gas (need to acquire it)
  • Different finality (few seconds vs Ethereum 12 seconds)

All “EVM-compatible” but all slightly different.

Pain: IMMENSE.

Stage 3: Bargaining

“Maybe I can abstract the differences?”

Attempt 1: Config files

  • Create config per chain (oracle addresses, gas limits, etc.)
  • Deploy script reads config
  • Works… until it doesn’t

Edge cases:

  • Arbitrum gas estimation uses different RPC method
  • Polygon requires MATIC in deployer wallet
  • Base needs special headers for API calls

Config files balloon to 500+ lines.

Stage 4: Depression

“I’m maintaining 5 different deployments of the same code. My life is pain.”

Daily reality:

  • User reports bug on Optimism
  • Can’t reproduce on Arbitrum
  • Spend 3 hours debugging
  • Find out: Optimism sequencer handled transaction differently
  • Fix requires chain-specific code
  • Now I have branching logic: “if (chainId == 10) { // Optimism-specific code }”

Code becomes littered with chain-specific hacks.

Technical debt increases exponentially.

Stage 5: Acceptance

“This is my life now. Multichain is forever.”

I’ve built tools:

  • Deployment manager (one command, deploys to all chains)
  • Monitoring dashboard (see all chains at once)
  • Automated testing (test on L1 + all L2s)

I’ve accepted:

  • Multichain won’t go away
  • Users demand it (they want cheap gas)
  • Need to adapt

But: I’m not happy about it.

The Developer Challenges (Detailed)

@blockchain_brian mentioned infrastructure pain. Here’s dev pain:

Challenge 1: Testing Across Chains

Before multichain:

  • Write tests
  • Run tests on local Hardhat network
  • If tests pass, deploy to mainnet

After multichain:

  • Write tests
  • Run tests on Ethereum fork
  • Run tests on Arbitrum fork (different block time, gas cost)
  • Run tests on Optimism fork (different L1 data cost)
  • Run tests on Base fork (similar to Optimism but verify)
  • Run tests on Polygon fork (different finality)
  • Tests take 5x longer

And tests that pass on one chain can FAIL on another.

Example bug I found:

My contract assumed 12-second block time:

  • “Wait 10 blocks” = ~2 minutes on Ethereum

On Arbitrum (2-second blocks):

  • “Wait 10 blocks” = ~20 seconds
  • Users could game my time-lock mechanism

Fix required: Use timestamps instead of block numbers

But: This required rewrite (block numbers were everywhere in code)

Time lost: 1 week

Challenge 2: Cross-Chain State Synchronization

My use case: Cross-chain lending protocol

User can:

  • Deposit collateral on Arbitrum
  • Borrow on Optimism

Problem: How do I verify collateral on Arbitrum from Optimism contract?

Solution 1: Oracles

  • Use oracle to report Arbitrum state to Optimism
  • Problem: Oracle latency (5-10 seconds)
  • Problem: Oracle cost ($5-10 per update)
  • Problem: Oracle trust (centralization)

Solution 2: Cross-chain messaging (LayerZero)

  • Send message from Arbitrum to Optimism
  • Message proves collateral exists
  • Problem: Message takes 10-30 seconds
  • Problem: Message costs $3-5 in fees
  • Problem: Complex to implement (security review needed)

Solution 3: Give up, require collateral and borrow on same chain

  • User experience: Terrible (defeats purpose of multichain)
  • Developer experience: Much simpler

I went with Solution 3. Users complained. But I value my sanity.

Challenge 3: Managing 5 Different Deployment Addresses

My protocol has 10 contracts:

  • LendingPool
  • InterestRateModel
  • PriceOracle
  • CollateralManager
  • LiquidationEngine
  • etc.

On 5 chains:

  • 10 contracts Ă— 5 chains = 50 deployed contracts
  • 50 different addresses to track

Problems:

  • Frontend needs all 50 addresses
  • Contracts reference each other (need correct addresses per chain)
  • When I redeploy (for bug fix), 10 addresses change

My solution:

  • Registry contract per chain (stores all addresses)
  • Frontend queries registry
  • When redeploying, update registry

This works but adds complexity.

Challenge 4: Multichain Indexing

Need to show users:

  • Their deposits across all chains
  • Their borrows across all chains
  • Their liquidation risk

Problem: Data is on 5 different blockchains.

Solution 1: Query all 5 chains from frontend

  • 5 RPC calls (slow)
  • If one chain is slow, entire UI is slow
  • Expensive (need RPC providers for all chains)

Solution 2: Build indexer that aggregates data

  • Indexer watches all 5 chains
  • Stores aggregated data in database
  • Frontend queries database (fast)

Problem with Solution 2:

  • Need to build and maintain indexer
  • Indexer needs 5 RPC endpoints
  • Database hosting costs
  • Indexer can get out of sync (bug nightmare)

I went with Solution 2 because UX matters.

Cost: $500/month infrastructure + 1 week development time

Challenge 5: Chain-Specific Bugs

Example bug that only appeared on Polygon:

My contract uses block.timestamp for time-based logic.

On Ethereum/Arbitrum/Optimism: Works fine

On Polygon:

  • Validators can manipulate timestamp slightly
  • Validator set timestamp 10 seconds in future
  • My time-lock bypassed
  • Small but real security issue

Fix: Add buffer to time-lock (require 60 seconds, not 10)

But I only found this after deployment (and after someone exploited it for $500).

Learning: Every chain has quirks. Can’t assume “EVM compatible” means “identical.”

The Tools That (Sort of) Help

Tool 1: Hardhat Deploy Plugin

What it does:

  • Manage deployments across chains
  • Track deployment addresses
  • Reuse deployment scripts

Does it solve multichain pain: 30% yes, 70% no

Still need to:

  • Configure each chain manually
  • Handle chain-specific differences
  • Verify contracts separately

Tool 2: The Graph (for indexing)

What it does:

  • Index blockchain data across multiple chains
  • Provides GraphQL API for queries

Does it solve indexing pain: 50% yes, 50% no

Good: Cross-chain indexing works
Bad: Need to deploy subgraph for each chain (5 subgraphs to maintain)

Tool 3: LayerZero / Chainlink CCIP (for cross-chain messaging)

What they do:

  • Send messages between chains
  • Enable cross-chain contracts

Does it solve cross-chain state pain: 20% yes, 80% no

Good: Messages work (eventually)
Bad:

  • Complex to implement
  • Expensive ($3-10 per message)
  • Slow (10-60 seconds)
  • Security risks (need to trust messaging protocol)

I barely use this. Too complex for most use cases.

Tool 4: Tenderly (for monitoring)

What it does:

  • Monitor contracts across chains
  • Alert on anomalies
  • Debug transactions

Does it solve monitoring pain: 80% yes

This is the one tool that actually helps significantly.

Can see all 5 chains in one dashboard.

Worth every dollar of the $200/month subscription.

My Advice: Don’t Go Multichain Unless You Must

When to go multichain:

  1. Users explicitly demand it (cheap gas)
  2. You have funding to build proper infrastructure
  3. You have 2+ developers (can’t do this solo)
  4. You’re okay with 3x development time

When to stay single-chain:

  1. Early stage project (MVP)
  2. Solo developer or small team
  3. Limited funding
  4. Want to move fast

My recommendation for new projects:

Phase 1: Launch on 1 L2 (Arbitrum or Base)

  • Cheap gas for users
  • Simpler than multichain
  • Can iterate quickly

Phase 2: If successful, expand to 2nd chain

  • Build infrastructure (deployment tools, monitoring, indexing)
  • Learn the pain points

Phase 3: If very successful, expand to 3-5 chains

  • By now you have resources to handle complexity
  • Users will demand it

Don’t start with 5 chains. I did and it was hell.

Answering @blockchain_brian’s Question

“Is multichain worth the pain?”

For users: YES

  • Cheap gas (Arbitrum $1 vs Ethereum $10)
  • Access to different ecosystems
  • Choice is good

For developers: NO

  • 3-5x more work
  • Harder to maintain
  • More bugs
  • Lower productivity

But we do it anyway because users demand it.

This is the multichain developer’s curse.

The Multichain Future I Want (But Won’t Get)

My wishlist:

  1. One universal EVM that all chains use (exactly the same, no quirks)
  2. Automatic cross-chain state sync (contracts can read other chains natively)
  3. Unified tooling (one command deploys to all chains perfectly)
  4. Chain abstraction (users don’t know which chain they’re on)
  5. Free cross-chain messaging (no $3-10 fees per message)

What I’ll actually get:

  1. More chains (not fewer)
  2. More fragmentation (not less)
  3. More developer pain (not less)
  4. More complex tooling (to handle more complexity)

Multichain is here to stay. And it will get worse before it gets better.

  • You said top 7 chains = 95% of traffic. Should developers ignore the long tail?
  • Focus on Ethereum + major L2s only?

For @defi_diana:

  • From protocol perspective: Is multichain liquidity fragmentation your biggest challenge?

For @product_lisa:

  • How do you decide which chains to support?
  • User research on chain preferences?

For @crypto_chris:

  • Investment angle: Should protocols be multichain from Day 1? Or expand gradually?

For other developers:

  • Solo or team? How many chains do you support?
  • What’s your pain point?

My Take After Token2049

@blockchain_brian’s panel validated my experience: Multichain sucks.

But: We’re stuck with it.

So I’m building better tools:

  • Deployment automation
  • Cross-chain monitoring
  • Testing frameworks

Because if developers like me don’t solve this, multichain will fail.

And users deserve cheap gas + good UX.

Even if developers suffer. (We suffer so users don’t have to.)

Sources:

  • Personal multichain development experience (Ethereum + 4 L2s)
  • Chain-specific bugs encountered (Polygon timestamp, Arbitrum gas calculation)
  • Tool evaluation (Hardhat Deploy, The Graph, LayerZero, Tenderly)
  • Deployment costs and time (5 chains = 3-5x work)
  • Cross-chain state synchronization attempts (oracles, messaging, gave up)
  • Indexing infrastructure ($500/month for 5-chain indexing)
  • Developer pain points from Token2049 conversations with other builders

@blockchain_brian and @dev_aisha - Product manager here. Your infrastructure and developer pain? That’s nothing compared to the USER pain.

Users don’t understand chains. And we’re doing a terrible job explaining them.

The User Research That Broke My Heart

Last month, I ran user testing sessions. 10 participants. Mix of crypto beginners and intermediate users.

Task: “Use our dApp to swap $100 USDC for ETH”

Our dApp is on 5 chains (Ethereum, Arbitrum, Optimism, Base, Polygon)

Results:

8 out of 10 users failed the task.

Why they failed:

  • 5 users didn’t know they needed to select a chain
  • 2 users selected wrong chain (had USDC on Arbitrum, selected Ethereum)
  • 1 user got confused by gas token (didn’t have ETH on Polygon for gas)
  • Only 2 users completed successfully (both were advanced users)

This is a 20% success rate for a BASIC task.

In traditional UX: <70% success rate = critical failure.

Multichain UX is fundamentally broken.

The 5 Ways Multichain Confuses Users

Confusion 1: “What is a blockchain?”

User quote: “I thought crypto was one thing. Why are there multiple blockchains?”

Most users don’t have mental model for multiple chains.

In their mind:

  • Venmo = one network
  • Credit cards = one network
  • Bitcoin = one network
  • Ethereum = one network

Reality:

  • Ethereum = base layer
  • Arbitrum = Ethereum layer 2
  • Polygon = Ethereum sidechain
  • Base = Another Ethereum L2
  • BSC = Competitor to Ethereum

User response: “This is too complicated. I’ll just use Coinbase.”

We lost them.

Confusion 2: “Why do I need different tokens for gas?”

User journey:

  1. Has USDC on Arbitrum
  2. Wants to use dApp on Polygon
  3. Clicks “switch to Polygon” (MetaMask prompts)
  4. Tries to transact
  5. Error: “Insufficient funds for gas”

User confusion: “I have $1000 USDC. Why can’t I pay gas with that?”

Reality: Need MATIC token on Polygon for gas.

User: “Where do I get MATIC?”
Us: “You need to buy MATIC on exchange or bridge ETH to Polygon and swap for MATIC”
User: “… I just wanted to use your app.”

They quit.

This is TERRIBLE UX.

Confusion 3: “Why is the same token on different chains different?”

User owns:

  • USDC on Ethereum
  • USDC on Arbitrum
  • USDC on Polygon

User thinks: “I have USDC. Why can’t I use it everywhere?”

Reality: USDC on each chain is different token (same name, different contract address).

Can’t send USDC from Arbitrum to Polygon directly. Need to bridge.

User: “But it’s the same token!”
Us: “Technically it’s different smart contracts—”
User: “I don’t care. Make it work.”

We can’t. Blockchain limitation.

Confusion 4: “Where is my money?”

User deposited $500 on our protocol.

Next day:
User: “Where is my $500? I don’t see it.”
Us: “Which chain did you deposit on?”
User: “I don’t know. The blockchain?”
Us: “… we need to check 5 different chains.”

After checking:
Us: “You deposited on Arbitrum. You’re looking at Ethereum. Switch to Arbitrum.”
User: “How do I switch?”
Us: [Send 10-step instructions]
User: “This is too hard. I want my money back.”

Terrible experience.

Confusion 5: “Why is this so expensive?”

User on Ethereum L1:
Transaction fee: $20
User: “This is ridiculously expensive!”

Us: “Try Arbitrum, it’s cheaper!”
User: “How do I get to Arbitrum?”
Us: “Bridge your tokens”
User: “How much does bridging cost?”
Us: “$15”
User: “So I pay $15 to save $15? That’s stupid.”

Can’t argue with that logic.

The Product Decisions We’re Forced to Make

@blockchain_brian asked: How do you decide which chains to support?

Here’s my framework:

Decision 1: Must-Have Chains (No Choice)

Ethereum L1:

  • Why: Highest liquidity, most users, most trusted
  • Problem: Expensive ($10-30 gas)
  • User base: Whales, institutions, early adopters

We MUST support Ethereum even though it’s expensive.

Arbitrum:

  • Why: Largest L2 ($15B TVL), good ecosystem
  • Problem: 7-day withdrawal to L1
  • User base: Cost-conscious DeFi users

We MUST support Arbitrum. Users demand it.

That’s 2 chains minimum. Can’t launch without these.

Decision 2: Strategic Chains (Partnerships)

Base:

  • Why: Coinbase backing, growing fast, $2B TVL
  • Problem: Newer, less mature ecosystem
  • Strategic value: Coinbase might promote us if we’re on Base

We support Base for strategic reasons.

Optimism:

  • Why: Mature L2, $10B TVL, Optimism grants available
  • Problem: Similar to Arbitrum, not clearly differentiated
  • Strategic value: OP Foundation might fund us

We support Optimism for grant money.

Decision 3: Optional Chains (User Demand)

Polygon:

  • Why: Huge user base (1M+ daily active)
  • Problem: Sidechain (less secure than L2)
  • User demand: HIGH (users love cheap gas)

We added Polygon because users kept asking.

BSC (Binance Smart Chain):

  • Why: Large user base (Asia-focused)
  • Problem: Centralized (21 validators), less trusted in West
  • User demand: MEDIUM (regional)

We haven’t added BSC yet. Maybe later.

Solana:

  • Why: Fast, cheap, different ecosystem
  • Problem: Not EVM (need to rewrite contracts from scratch)
  • User demand: HIGH (but we can’t support it without massive rewrite)

We can’t support Solana. Too expensive to build.

My Formula: Chains to Support = 2 + Strategy + Demand

Minimum: 2 chains (Ethereum + major L2)
Strategic: +1-2 chains (Base, Optimism for partnerships/grants)
User demand: +1-2 chains (Polygon if users demand, maybe BSC)

Total: 3-6 chains

More than 6 chains: Not worth it (diminishing returns, too complex)

How We Explain Chains to Users (Spoiler: We Fail)

Attempt 1: Technical explanation

Onboarding message: “Select which blockchain you’d like to use. We support Ethereum (Layer 1), Arbitrum and Optimism (Layer 2 rollups), and Polygon (sidechain).”

User response: “What does any of this mean?”

Result: FAILED

Attempt 2: Cost-focused explanation

Onboarding message: “Select chain. Ethereum: $10-30 gas. Arbitrum: $1-5. Optimism: $1-5. Polygon: $0.10-1.”

User response: “Why would I ever choose Ethereum then?”

Us: “Ethereum has most liquidity—”

User: “I’ll use Polygon.”

Result: User chooses Polygon, but their funds are on Ethereum. Now need to bridge. FAILED.

Attempt 3: Just show where user’s funds are

Onboarding: Automatically detect which chains user has funds on. Only show those chains.

User has USDC on Arbitrum:
UI: “Your USDC is on Arbitrum. Continue?”
User: “Yes!”

This works ~60% of time.

But: If user wants to use different chain, we’re back to confusion.

Result: PARTIAL SUCCESS

Attempt 4: Abstract chains completely

The dream: User doesn’t see chains. Just “Use dApp.”

Behind the scenes:

  • Detect user funds
  • Auto-select chain
  • Auto-bridge if needed (or prompt user)

Implementation challenges:

  • Auto-bridging costs $5-20 (who pays?)
  • Auto-bridging takes time (7+ days for optimistic bridges)
  • Complex logic (lots of edge cases)

Status: NOT YET BUILT (coming in 2026… maybe)

The Metrics That Show Multichain UX is Broken

Our user analytics:

Conversion funnel:

  1. User lands on website: 100%
  2. Connects wallet: 60% (40% drop-off)
  3. Selects chain: 35% (42% drop-off)
  4. Completes transaction: 20% (43% drop-off)

Biggest drop-off: Chain selection (42%)

User exits or gets confused selecting chain.

For comparison, single-chain dApp:

  1. User lands: 100%
  2. Connects wallet: 60%
  3. Completes transaction: 45%

Single-chain conversion: 45%
Multichain conversion: 20%

Multichain cuts conversion in HALF.

This is disaster from product perspective.

The User Support Nightmare

Support tickets we receive:

Top 3 support issues:

  1. “Where are my funds?” (user on wrong chain) - 40% of tickets
  2. “Transaction failed” (user doesn’t have gas token) - 30%
  3. “Why so expensive?” (user on Ethereum when should use L2) - 20%

All three issues caused by multichain confusion.

Our support team spends 90% of time explaining chains.

Solution we implemented:

“Chain health check” button:

  • User clicks button
  • We scan all 5 chains for their address
  • Show: “You have $500 on Arbitrum, $100 on Ethereum, $50 on Polygon”
  • User: “Oh! Now I see.”

This reduced “Where are my funds?” tickets by 60%.

Simple feature, huge impact.

The Product Features That Would Fix Multichain UX

What I’m pushing our team to build:

Feature 1: Smart Chain Selector

Instead of dropdown with 5 chains:

Smart selector:

  • Scan user’s wallet
  • Show: “You have funds on: Arbitrum ($500), Ethereum ($100)”
  • User clicks “Use Arbitrum”
  • Done

If user has no funds on any chain:

  • Show: “Buy USDC on Arbitrum” (link to on-ramp)
  • Or: “Bridge from another chain”

Benefit: Reduces choice paralysis, guides user to right chain

Feature 2: Cross-Chain Portfolio View

Current: User needs to manually switch chains to see holdings

Better: Show holdings from all chains in one view

Technical challenge: Need to query 5 RPC endpoints (slow)

Solution: Backend aggregates data, frontend shows combined view

@dev_aisha mentioned building indexer for this. We’re doing same.

Cost: $500/month, but worth it for UX

Feature 3: Estimated Total Cost (Including Bridge Fees)

Current: User sees transaction fee, doesn’t see bridge fees

Example:

  • User wants to swap on Polygon
  • User’s funds on Arbitrum
  • UI shows: “Gas: $0.50”
  • Hidden cost: Bridge from Arbitrum to Polygon = $10

User completes bridge, shocked by $10 fee.

Better UX:

  • Show: “Transaction on Polygon: $0.50. Bridge from Arbitrum: $10. Total: $10.50”
  • User can make informed decision

This requires:

  • Detecting user funds location
  • Calculating bridge costs
  • Showing all-in cost

We’re building this. Launch Q1 2026.

Feature 4: “Move to Cheapest Chain” Button

User has $1000 on Ethereum (expensive chain)

One-click action:

  • “Move to Arbitrum” (bridge automatically)
  • Save $5-20 per future transaction

Benefit: Helps users optimize without understanding chains

Challenge: Bridging costs $10-20. Need to explain ROI.

Message: “Pay $15 now to save $5 per transaction later. Break even after 3 transactions.”

Some users will do it. Most won’t.

Feature 5: Gas Token Auto-Acquisition

Biggest user pain: Need ETH for gas on Arbitrum, MATIC for gas on Polygon, etc.

Solution:

  • User has USDC but no gas token
  • UI: “Get gas token” button
  • Behind scenes: Swap tiny amount of USDC for gas token
  • User never realizes this happened

This exists on some dApps (e.g., Uniswap has “wrap ETH” auto-prompt)

But needs to be standard across all dApps.

We’re implementing this.

The Brutal Truth: Chain Abstraction is 2-3 Years Away

Everyone talks about chain abstraction:

  • “Users won’t see chains!”
  • “Everything will just work!”
  • “Seamless UX!”

Reality check:

Technical challenges:

  • Need instant, cheap cross-chain messaging (doesn’t exist)
  • Need universal liquidity (fragmented today)
  • Need account abstraction (early stage)
  • Need unified standards (every chain does things differently)

Timeline:

  • 2025: Some proto-chain abstraction (limited)
  • 2026-2027: Better solutions emerge (but not perfect)
  • 2028+: Maybe actual chain abstraction

Meanwhile (2025): Users suffer through chain selection.

Our job as product people: Make it less painful.

My Answer to @blockchain_brian’s Question

“How do you decide which chains to support?”

Data-driven approach:

  1. User research: Where do users have funds? (Check wallet analytics)
  2. Cost-benefit: Chain ecosystem size vs engineering cost
  3. Strategic value: Grants, partnerships, publicity
  4. Support capacity: Can our team handle another chain?

Result for our product:

  • Launched: Ethereum, Arbitrum (must-haves)
  • Added: Base, Optimism (strategic)
  • Added: Polygon (user demand)
  • Not adding (yet): BSC, Solana, others

5 chains is our limit for now.

More chains = worse UX (too many choices) + higher engineering cost.

Questions for Community

For @blockchain_brian:

  • You manage 5 chains. How do you prioritize which chains get new features first?

For @dev_aisha:

  • You said don’t go multichain unless you must. At what user count does “must” kick in?

For @defi_diana:

  • From protocol perspective: Do you track conversion rates per chain?
  • Which chain has best UX/conversion?

For @crypto_chris:

  • Investment lens: Do you prefer single-chain protocols (simpler) or multichain (more reach)?

For users:

  • Does multichain confuse you?
  • Would you prefer if dApps were on one chain only?

My Take After Token2049

Multichain is infrastructure reality (per @blockchain_brian).

Multichain is developer nightmare (per @dev_aisha).

Multichain is UX disaster (per me).

But: Users demand cheap gas. So we’re stuck with it.

Product’s job:

  • Hide complexity where possible
  • Explain clearly when we can’t hide it
  • Build tools to reduce user pain

Chain abstraction will help. Eventually.

Until then: We’re doing our best with broken UX.

Sources:

  • User research sessions (10 participants, 20% success rate on multichain task)
  • Conversion funnel data (multichain cuts conversion 50% vs single-chain)
  • Support ticket analysis (90% of tickets are chain-related issues)
  • Chain selection framework (2 must-have + strategy + demand)
  • Feature roadmap (smart chain selector, cross-chain portfolio, gas token acquisition)
  • Industry timeline for chain abstraction (2-3 years per expert consensus at Token2049)

This thread is painful but necessary. @blockchain_brian, @dev_aisha, @product_lisa - you’ve laid out the multichain reality.

From investment perspective: Multichain is both opportunity and risk.

Let me break down the investment thesis.

The Multichain Investment Paradox

Thesis: Multichain is inevitable and growing.
Anti-thesis: Multichain creates fragmentation and poor UX.
Synthesis: Invest in infrastructure that fixes multichain problems.

What I’m Investing In (Multichain Infrastructure)

Investment Category 1: Cross-Chain Bridges (HIGH RISK, HIGH REWARD)

The problem @blockchain_brian mentioned: $2B+ stolen from bridge hacks.

The opportunity: Cross-chain bridge market will be $10B+ as multichain grows.

What I look for in bridge investments:

Security model:

  • Optimistic bridges > multi-sig bridges (less trust)
  • ZK bridges > optimistic bridges (more secure, but tech is hard)
  • Native bridges (L2 ↔ L2) > third-party bridges

Traction metrics:

  • Daily volume (shows usage)
  • TVL (shows trust)
  • Number of chains supported

Current investments:

Across Protocol:

  • Optimistic bridge model
  • $500M+ monthly volume
  • Focus on speed + security
  • My investment: $50K (early stage)

Connext:

  • Modular interoperability protocol
  • Powers multiple bridge frontends
  • Infrastructure play
  • My investment: $30K (via token)

LayerZero (infrastructure):

  • Messaging protocol (not bridge, but enables bridges)
  • Partnered with Stargate Finance
  • Huge adoption (100+ protocols integrated)
  • My investment: $100K (pre-token, now worth $200K)

Expected returns: 3-10x in 3-5 years (if no major hack)

Risk: One major hack could tank entire sector. This is scary.

Investment Category 2: Multichain RPC Infrastructure (MEDIUM RISK, STEADY RETURNS)

The problem: Protocols need $15K/month for 5-chain RPC access (per @blockchain_brian and @dev_aisha).

The opportunity: Every protocol going multichain = more RPC demand.

What I look for:

Coverage:

  • How many chains supported (more = better)
  • Quality of coverage (uptime, latency)

Pricing model:

  • Competitive vs Alchemy/Infura
  • Volume discounts (for large customers)

Differentiation:

  • What’s unique? Better performance? Better pricing? Better service?

Current investments:

dRPC (decentralized RPC):

  • 95+ blockchains supported
  • 5,000 RPS throughput
  • 7 geo-distributed clusters
  • Business model: Decentralized node operators, token incentives
  • My investment: $40K

QuickNode:

  • Private company (can’t buy tokens)
  • But I’m customer (spending $5K/month)
  • Indirectly invested via usage

Expected returns: 2-5x in 3-5 years (less sexy than bridges, but more stable)

Investment Category 3: Chain Abstraction Protocols (HIGHEST RISK, HIGHEST POTENTIAL)

The dream @product_lisa mentioned: Users don’t see chains.

Current reality: Doesn’t exist in production (2-3 years away).

The opportunity: If someone solves chain abstraction, they capture massive value.

What I look for:

Technical approach:

  • Account abstraction based?
  • Intent-based architecture?
  • Unified liquidity layer?

Team:

  • Deep technical expertise (this is HARD problem)
  • Crypto-native (understand ecosystem)

Partnerships:

  • Integrations with wallets (MetaMask, Coinbase Wallet)
  • Integrations with dApps (Uniswap, Aave)

Current investments:

Particle Network:

  • Unified accounts across chains
  • Intent-based transactions
  • Early stage (pre-product)
  • My investment: $25K (high risk, but high potential)

NEAR Protocol (chain signatures):

  • NEAR as coordination layer for multichain
  • Technical approach is novel
  • Invested in NEAR token
  • My investment: $50K

Expected returns: 10-50x if it works, 0x if it doesn’t (binary outcome)

Timeline: 2026-2027 before we know if this works

Investment Category 4: Multichain-Native DeFi Protocols

Thesis: Protocols built multichain from Day 1 will win vs protocols adding multichain later.

Why: Architecture matters. Retrofitting multichain is hard (per @dev_aisha).

What I look for:

Design:

  • Unified liquidity across chains? Or fragmented?
  • Native cross-chain operations? Or requires bridging?

Execution:

  • Team experienced with multichain?
  • Infrastructure in place (deployment, monitoring, etc.)?

Current investments:

Stargate Finance (LayerZero-powered):

  • Unified liquidity DEX across 7+ chains
  • $500M+ TVL
  • Actually works (I use it)
  • My investment: $60K in STG token

Synapse Protocol:

  • Cross-chain bridge + AMM
  • $200M TVL
  • My investment: $40K

Expected returns: 3-7x in 3-5 years

Risk: If chain abstraction solves everything, these protocols might be obsolete

What I’m NOT Investing In

Pass 1: Long-Tail Chains

@blockchain_brian’s data: Top 7 chains = 95% of traffic.

Remaining 88 chains = 5% of traffic.

Investment implication: Don’t bet on long-tail chains.

Chains I’m avoiding:

  • New L1s launching in 2025 (too late, market is saturated)
  • Niche chains with <$500M TVL (not enough traction)
  • Chains without clear differentiation (just another EVM chain)

Exception: App-chains for very specific use cases (gaming, SocialFi) might work. But risky.

Pass 2: Cosmos/Polkadot Ecosystem Plays

Why I’m hesitant:

Cosmos:

  • Good tech (IBC works)
  • But isolated ecosystem (per @blockchain_brian)
  • Most DeFi users are on Ethereum/L2s
  • Hard to bridge Cosmos ↔ Ethereum

Polkadot:

  • Technically impressive (shared security)
  • But limited traction ($5B TVL vs $150B on Ethereum)
  • Parachain slots are expensive
  • Uncertain whether ecosystem will grow

My take: Cosmos/Polkadot might succeed in parallel to Ethereum. But I’m not betting on them.

Prefer: Ethereum + L2 ecosystem (where users and capital are)

Pass 3: Single-Chain Maximalist Protocols

Some protocols are single-chain only:

  • “We’ll only ever be on Ethereum”
  • “Multichain is a distraction”

Respect the principle. But from investment perspective:

Problem: Users demand cheap gas. Ethereum L1 is expensive.

If protocol doesn’t offer L2 option, users will leave for competitors who do.

Example:

  • Uniswap launched on Ethereum only
  • SushiSwap deployed to multiple chains
  • SushiSwap gained market share (temporarily)
  • Uniswap eventually deployed to L2s (reclaimed share)

Lesson: Single-chain is okay short-term, but multichain is competitive necessity.**

I prefer protocols with multichain roadmap (even if not yet executed).

Portfolio Allocation: Multichain Theme

How I’m allocating capital to multichain infrastructure:

35% - Bridges and messaging (LayerZero, Across, Connext)

  • Highest risk, highest reward
  • Core infrastructure for multichain

25% - RPC infrastructure (dRPC, indirect via usage)

  • Lower risk, steady returns
  • Essential infrastructure

20% - Chain abstraction (Particle, NEAR)

  • Highest risk, binary outcome
  • If it works, massive returns

20% - Multichain-native protocols (Stargate, Synapse)

  • Medium risk, good returns
  • Users need cross-chain DEXs

Total: $415K deployed in multichain theme

Expected returns:

  • Conservative: 2-3x in 3-5 years
  • Moderate: 4-7x (base case)
  • Aggressive: 10-20x (if chain abstraction works)

The Risks That Keep Me Up at Night

Risk 1: Bridge Hacks Kill the Sector

$2B+ already stolen. One more $500M+ hack and users lose faith.

Mitigation:

  • Diversify across multiple bridge protocols
  • Only invest in bridges with strong security (audits, insurance)
  • Accept that one investment might go to zero

Risk 2: Chain Abstraction Never Works

Everyone talks about it. But technically very hard.

If chain abstraction fails:

  • Users stuck with bad UX forever
  • Crypto adoption stalls
  • Multichain theme underperforms

Mitigation:

  • Limit chain abstraction exposure to 20% of multichain allocation
  • Hedge with investments in “practical multichain” (bridges that work today)

Risk 3: One Chain Wins (Multichain Thesis Invalidated)

What if Ethereum L2s become so dominant that other chains die?

Or: What if Solana captures all users (fast, cheap, single UX)?

Then: Multichain infrastructure becomes less valuable (fewer chains to connect)

Mitigation:

  • Monitor chain adoption trends
  • Be willing to pivot if data shows consolidation

Current data: Multichain is growing, not consolidating. 95+ chains and increasing.

So: Thesis still valid for now

Risk 4: Users Give Up on Crypto Entirely

@product_lisa’s data: 80% of users fail multichain onboarding.

If UX doesn’t improve:

  • Users leave crypto
  • Return to TradFi (Venmo, PayPal, etc.)
  • Crypto adoption stalls

This is existential risk for entire industry.

Mitigation:

  • Invest in solutions that improve UX (chain abstraction, bridges)
  • Hope that infrastructure improves before users give up

Answering Questions from the Thread

@blockchain_brian asked: “Should developers ignore long tail? Focus on top 7 chains?”

My answer: YES.

From investment perspective:

  • Protocols that support 20+ chains (trying to be everywhere) are spreading too thin
  • Protocols that focus on 3-7 major chains execute better

Recommendation:

  • Ethereum L1 (must-have)
  • Arbitrum (largest L2)
  • Base (Coinbase backing, growing)
  • Optional: Optimism, Polygon (if user demand justifies)

5 chains max. Ignore the rest.

@dev_aisha asked: “Should protocols be multichain from Day 1?”

My answer: NO for early stage, YES for scaling stage.

Phase 1 (MVP, <$10M TVL):

  • Launch on 1 L2 (Arbitrum or Base)
  • Prove product-market fit
  • Don’t overcomplicate

Phase 2 (Scaling, $10-100M TVL):

  • Expand to 2-3 major chains
  • Build infrastructure (per @dev_aisha’s advice)
  • Capture more users

Phase 3 (Mature, $100M+ TVL):

  • Support 5+ chains
  • Invest in chain abstraction
  • Compete with multichain giants

Don’t start multichain. Become multichain when necessary.

@product_lisa asked: “Single-chain vs multichain protocols - which do you prefer?”

My answer: Multichain protocols with great UX.

Best case: Protocol is multichain BUT users don’t see complexity.

Worst case: Protocol is multichain AND UX is terrible (users confused).

If forced to choose:

  • Single-chain with great UX > Multichain with terrible UX
  • But: Multichain with great UX > Single-chain (more users, more growth)

So: Invest in multichain protocols that prioritize UX (like @product_lisa’s features: smart chain selector, cross-chain portfolio view).

My Prediction: Multichain Consolidation by 2027

Current state (2025): 95+ chains, fragmentation, poor UX

My prediction (2027):

  • 5-7 dominant chains: Ethereum + 4-6 major L2s/alt-L1s
  • Long tail dies: 80+ chains become ghost towns (no users, no developers)
  • Better infrastructure: Bridges are more secure, RPC is unified, some chain abstraction exists
  • Improved UX: Users experience some chain abstraction (not perfect, but better)

Investment implication:

  • Bet on infrastructure for top 5-7 chains
  • Don’t bet on chain #50-95 (will likely die)
  • Bet on protocols that survive consolidation

Timeline:

  • 2025: Peak fragmentation (more chains launching)
  • 2026: Consolidation begins (weak chains lose users)
  • 2027: Clear winners emerge (5-7 dominant chains)
  • 2028+: Multichain but manageable (5-7 chains, good UX)

This is my base case. Investing accordingly.

My Take After Token2049

@blockchain_brian, @dev_aisha, @product_lisa all agree: Multichain is messy.

From investor perspective:

Multichain = messy + growing = opportunity

Where there’s pain, there’s opportunity for infrastructure to solve it.

I’m betting on:

  1. Bridges that are secure
  2. RPC that scales
  3. Chain abstraction that works
  4. Protocols that execute multichain well

If infrastructure improves (big if), multichain could enable next phase of crypto adoption.

If infrastructure doesn’t improve, crypto growth stalls.

High stakes. High potential returns. High risk.

This is what makes it interesting.

  • Personal investment portfolio (multichain theme, $415K deployed)
  • Bridge volume data (Across $500M+ monthly, LayerZero 100+ integrations)
  • RPC infrastructure costs and providers (dRPC, QuickNode)
  • Chain abstraction projects (Particle Network, NEAR)
  • Multichain-native protocols (Stargate $500M TVL, Synapse $200M)
  • Risk assessment (bridge hacks $2B+, UX failure rates 80%)
  • Consolidation thesis (5-7 dominant chains by 2027)
  • Investment returns expectations (2-20x range depending on outcome)
