The Rise of AI Agents in DeFi: Transforming Multi-Chain Strategies
Most DeFi users still open five browser tabs to complete a single yield strategy — checking rates on Aave, bridging assets on Stargate, depositing on Curve, and hoping they don't miss a gas spike. But a quiet revolution is underway. Autonomous AI agents are now doing all of that silently, across multiple blockchains simultaneously, while you sleep.
In 2025, AI agent activity on blockchains surged 86%. Fetch.ai agents alone manage over $1 billion in Hyperliquid derivatives, executing 100x leveraged trades autonomously. Yearn's AI-driven vaults optimize $5 billion across yield pools without human input. And platforms like XION and Particle Network are building the abstraction layers that make all of this invisible to end users. The question is no longer whether AI agents can orchestrate multi-chain DeFi — it's how fast the infrastructure will mature, and what it means for everyone from retail users to institutional desks.
From Manual Clicking to Intent Execution
The shift from manual DeFi to agentic DeFi is best understood through the concept of "intent abstraction." In traditional DeFi, users must specify exactly how they want something done: which protocol, which chain, which token, which gas price. Intent-based systems flip this model entirely. You declare what you want — "I want the highest yield on my stablecoins across Ethereum and Solana" — and AI agents handle execution autonomously.
This isn't a distant promise. Large language models (LLMs) are already being integrated into DeFi interfaces that translate natural language into complex on-chain actions. A user can now type "rebalance my portfolio into high-yield stablecoins across three chains" and watch the agent execute token swaps, bridge transfers, protocol deposits, and gas management without any manual steps.
The underlying technical foundation that makes this possible is account abstraction — specifically Ethereum's EIP-7702, which went live with the Pectra upgrade in May 2025. EIP-7702 enables externally owned accounts (EOAs) to temporarily delegate execution to smart contracts, allowing AI agents to act on behalf of user wallets. This means AI systems can claim airdrops, rebalance positions, and optimize yields automatically while the original private key holder retains ultimate control.
The Chain Abstraction Infrastructure Race
For AI agents to execute truly multi-chain strategies, they need an underlying infrastructure layer that treats all blockchains as one unified execution environment. Two projects are leading this race: XION and Particle Network.
XION describes itself as "the first walletless L1 blockchain purpose-built for consumer adoption." Its chain abstraction technology decouples the user interface from the underlying blockchain infrastructure at the protocol level. Users can onboard via email, social logins, or biometrics — no seed phrases, no browser extensions. XION's abstracted interoperability lets a single account interact with Solana, Avalanche, Injective, and other networks without manual bridging. By mid-2025, over 150 global brands, including Uber, Amazon, and BMW, were using XION's infrastructure for consumer campaigns. XionSpace, the platform's AI-powered digital asset product, integrates advanced on-chain AI capabilities directly with XION's chain abstraction, representing one of the first live deployments of AI-native chain-abstracted applications.
Particle Network takes a complementary approach through Universal Accounts — a system that gives users a single address, balance, and interaction point across the entire multi-chain ecosystem. Universal Accounts launched into production at the start of 2025 via UniversalX, the first chain-agnostic trading platform. By Q1 2025, UniversalX hit $5.9 million in daily trading volume with a 15,154% increase from the prior quarter. Over 90 development teams, including Singularity Finance for AI-driven DeFi and RWA strategies, are integrating Particle Network's Universal Accounts into their products. Monthly active Universal Account users grew above 30% monthly from Q1 through mid-year.
The key difference between these two approaches: XION operates as its own L1 with chain abstraction baked into the protocol, while Particle Network functions as a middleware layer that can plug into any existing blockchain. Both serve AI agents well, but XION's integrated approach offers deeper native support, while Particle's flexibility allows broader ecosystem adoption.
The Key Players Building Agentic DeFi
Beyond infrastructure, a distinct ecosystem of AI agent platforms is emerging to fill the strategy and execution layer.
Artificial Superintelligence Alliance (ASI) — formed through the merger of Fetch.ai, SingularityNET, and Ocean Protocol — is the largest decentralized AI infrastructure play. Its uAgents turn data streams, ML models, and APIs into on-chain agents that can be deployed and orchestrated into complex workflows via the Agentverse marketplace. Autonomous ASI agents currently manage approximately $2 billion in DeFi and supply chain tasks with a $2.34 billion market cap.
Autonolas (Olas) focuses on user-owned agents with pre-built roles like "Prediction Trader," "BabyDegen" (AI-powered DeFi trading), and Optimus (portfolio manager). Olas agents work across Base, Optimism, and Mode networks, managing diversified stablecoin positions and liquidity provider strategies 24/7. Autonoly, a related automation platform, claims to process 500,000+ automated DeFi workflows monthly, cutting gas fees by 38% through optimized transaction batching.
Delysium's YKILY AI Agent Network builds autonomous agents that communicate, transact, and evolve on-chain, with its flagship Lucy OS providing a plug-and-play interface for deploying DeFi agents. Delysium has formed enterprise partnerships with Google, Microsoft, NVIDIA, Polygon, and BNB Chain — signaling that mainstream enterprise adoption of on-chain AI agents is no longer hypothetical.
What Multi-Chain Orchestration Actually Looks Like
Let's make this concrete. Here's a real-world scenario a modern AI agent system can execute:
A user deposits $50,000 USDC on Ethereum and sets a simple objective: "maximize yield while keeping 30% liquid at all times." The agent system then:
- Monitors yield rates across Aave (Ethereum), Kamino (Solana), and Morpho (Base) in real-time
- Identifies that Kamino is offering 8.2% APY vs Aave's 4.1% on comparable risk
- Bridges 40% of the position to Solana via the optimal bridge route (minimizing slippage and fees)
- Deposits into Kamino's USDC vault
- Maintains a 30% liquidity buffer on Ethereum in a liquid staking pool
- Executes the entire operation in a single transaction bundle using EIP-7702 account delegation
The user's experience: they set a goal and confirmed one transaction. The agent handled bridge selection, gas optimization across two chains, protocol comparison, and deposit execution. Without multi-chain AI orchestration, this same workflow would require approximately 45 minutes of manual research and 6-8 separate transactions.
The $20-39 Billion Market Nobody Talks About Enough
The AI x Crypto market expanded from approximately $14 billion in late 2024 to an estimated $20-39 billion by mid-2025, with forecasts projecting $47 billion by 2034 at a 28.9% compound annual growth rate. But these headline numbers obscure where the real growth is happening: not in speculative AI tokens, but in infrastructure and tooling for agentic applications.
Venture capital is following this signal. AI-related crypto deals represented 37% of all VC investment in the sector by mid-2025 — the highest concentration ever recorded. This isn't token speculation; it's funding for the wallets, oracles, identity systems, and execution rails that AI agents need to operate on-chain at scale.
The infrastructure gap remains significant. For AI agents to manage real institutional capital across multiple chains, they need:
- Verifiable identity: How do protocols know they're interacting with an authorized agent vs. a malicious bot? Projects like ERC-8004 (AI agent identity standard) and KYA ("Know Your Agent") frameworks are addressing this
- Cross-chain oracle reliability: Real-time data across chains without introducing new trust assumptions
- Gas abstraction: Agents shouldn't need to hold native gas tokens on every chain they touch — XION and Particle Network both solve this
- Auditability: On-chain proof that agents executed according to their stated policies, not covertly
Risks: Autonomous Agents Are Also Autonomous Attack Vectors
The same capabilities that make AI agents powerful make them dangerous when misconfigured or compromised. In 2025, several incidents demonstrated that agentic DeFi introduces attack surfaces that traditional DeFi didn't have.
When an AI agent has delegated authority over a wallet, a compromised agent key or flawed decision model can drain funds faster than any manual attacker. The 2025 Trove Markets incident on Hyperliquid demonstrated how AI-driven liquidations can cascade in ways human traders wouldn't, creating systemic risk in thin markets.
Smart contract auditors have identified "agent poisoning" as an emerging threat vector — where adversarial inputs trick an AI model into executing unintended transactions. Unlike smart contract bugs, which are static, AI agents can be manipulated through the data they consume, making defenses harder to implement.
Regulatory uncertainty compounds this. Most jurisdictions have no framework for AI agent liability in DeFi. If an AI agent drains a position due to a model error, is the protocol liable? The developer? The user who granted delegation? This legal ambiguity is slowing institutional adoption despite clear technical capability.
The Road Ahead: 2026 and Beyond
Several developments are poised to accelerate AI agent adoption across multi-chain environments in the coming year:
The proliferation of EIP-7702-compatible wallets — MetaMask, Coinbase Wallet, and others — means account abstraction is no longer a theoretical feature but an available primitive. As more users upgrade to smart account functionality, the installed base for AI agent delegation grows.
Cross-chain messaging protocols like LayerZero and Hyperlane are building the transport layer that AI agents use to execute cross-chain strategies atomically. As these mature, the current limitation of sequential cross-chain execution (bridge, wait for confirmation, execute) will give way to near-simultaneous multi-chain coordination.
The "KYA" movement — Know Your Agent — is gaining traction as protocols realize they need to authenticate and authorize AI agents just as they do human users. Standards being developed now will determine whether AI agents become first-class citizens of the on-chain economy or remain second-class participants.
Perhaps most importantly, the competition between XION's integrated approach and Particle Network's middleware model will reveal which architecture developers prefer for building AI-native applications. The winner of this infrastructure race will likely become the default execution environment for the next generation of autonomous DeFi.
