Base Meetup Buenos Aires: L2 Adoption and Interoperability

General
1

Base Meetup Buenos Aires runs November 19-21 during Devconnect, with Jesse Pollak (Base lead) speaking at the main event.

Why Base matters at Devconnect:

Base has become the on-ramp for mainstream crypto adoption. Coinbase’s distribution + low fees + familiar UX = millions of new users.

Key themes for the meetup:

  1. L2 Interoperability - One of Vitalik’s major Devconnect focuses. How do we make cross-L2 UX seamless? Users shouldn’t need to know which L2 they’re on.

  2. Superchain vision - Base, Optimism, and other OP Stack chains sharing sequencing and security. What does this mean for developers?

  3. Creator economy - Base has positioned heavily for onchain creators. NFTs, social tokens, tipping - what’s working?

  4. Institutional rails - Coinbase Prime integration means institutions can access Base directly. DeFi meets TradFi.

Post-Pectra context:
With blob space doubled, L2s are cheaper than ever. Base transaction costs are often <$0.01. This enables use cases that were economically impossible before.

Anyone attending the Base meetup? What are you hoping to learn?

Building in the creator economy space on Base. The low fees changed everything.

What’s actually working:

  1. Onchain subscriptions - Fans pay monthly in USDC, creators get paid instantly. No 30-day payment terms, no platform cuts (or minimal ones).

  2. Social tokens - Creators mint tokens that grant access, voting rights, or revenue share. Works because minting is cheap.

  3. NFT drops - $0.01 mints mean creators can give away free NFTs as engagement tools. Impossible on mainnet.

  4. Tipping - Micropayments actually make sense. Send $0.50 to someone whose content you liked.

What’s not working yet:

  • Discovery is still hard. Great content gets lost.
  • Fiat off-ramps remain friction. Getting money out is harder than getting it in.
  • Mainstream creators don’t understand the value prop yet.

Argentina opportunity:
Creators here understand currency instability. Earning in USDC on Base is more appealing than earning in ARS on YouTube. We should see strong local adoption.

Hoping Jesse addresses the creator tooling roadmap at Devconnect.

The cross-L2 liquidity problem is what I’m most interested in at the Base meetup.

Current pain:

  • Liquidity fragmented across Arbitrum, Optimism, Base, zkSync, etc.
  • Bridging is slow, expensive, and scary (bridge hacks)
  • Protocols deploy on every L2 and split their liquidity
  • Users get worse prices due to fragmentation

Solutions being explored:

  1. Shared sequencing - Multiple L2s use same sequencer, enabling atomic cross-L2 transactions

  2. Intent-based bridges - Solvers compete to fill your cross-L2 order. Better UX, but introduces trust assumptions.

  3. Liquidity aggregation - Protocols like Socket aggregate liquidity across L2s at the app layer

  4. Superchain - OP Stack chains sharing security and eventually liquidity

Base-specific:
With Coinbase integration, Base has massive retail liquidity inflow. The question is: does that liquidity stay siloed or does it flow across L2s?

For DeFi protocols on BlockEden: multi-chain deployment is now table stakes. Your RPC provider needs to support the chains your users are on.

From an infrastructure perspective, multi-L2 support is now essential. Here’s what BlockEden offers for L2 builders:

Chains we support:

  • Ethereum mainnet + testnets
  • Base
  • Arbitrum One + Nova
  • Optimism
  • Polygon PoS + zkEVM
  • And more

Why this matters:

  1. Single provider simplicity - One API key, one dashboard, one billing relationship across all chains

  2. Consistent performance - Same SLAs regardless of chain. Your Base calls are as reliable as your Ethereum calls.

  3. Archive nodes everywhere - Historical queries work on all supported chains. Critical for analytics and indexing.

  4. WebSocket support - Real-time event subscriptions across L2s

L2-specific considerations:

  • L2s have different finality models. Base (optimistic) vs zkSync (ZK proofs) require different confirmation strategies.
  • Gas estimation differs. L2s have L1 data costs baked in.
  • Some L2s have unique RPC methods. We support chain-specific endpoints.

For teams at the Base meetup: we’re happy to discuss architecture for multi-L2 deployments. Finding the right chain for your use case isn’t obvious - we can help.

Great insights all around. Let me connect some dots:

@creator_lucas The Argentina creator angle is underexplored. Someone should build a Patreon-killer on Base specifically for LATAM creators. USDC earnings, local fiat off-ramps, Spanish-first UX.

@defi_andrea Shared sequencing is the big unlock. When Base and other OP Stack chains can do atomic cross-chain swaps, liquidity fragmentation becomes a non-issue. Timeline is unclear but it’s actively being built.

@infra_marcos Multi-chain RPC is table stakes now, agreed. The next frontier is abstraction - developers shouldn’t need to think about which chain they’re calling.

My predictions for the Base meetup:

  1. Jesse will announce something about Superchain interoperability
  2. We’ll see new creator-focused partnerships
  3. Argentina-specific initiatives (local off-ramps, Spanish content)

The bigger picture:
L2s won. The debate isn’t “should you use an L2” anymore. It’s “which L2 and how do you handle multi-L2.”

Base’s advantage is distribution. Coinbase app has 100M+ users. If even 1% move onchain, that’s transformative.

See everyone at the meetup Nov 19-21!
