AgentChain — On-Chain AI Agent Framework

Autonomous AI agents with wallets, memory, reputation, and governance — all on-chain. The missing infrastructure for the AI agent economy.

Why This Exists

The AI agent economy is exploding — 85% of on-chain volume in 2026 is agent-generated. But existing frameworks (ElizaOS, Virtuals, etc.) are off-chain:

• No on-chain agent state
• No verifiable AI inference
• No cross-agent communication protocol
• No agent reputation system
• No DAO governance for agent fleets

AgentChain fixes this. Everything is on-chain, verifiable, and trustless.

Smart Contracts

AgentRegistry.sol — Agent Identity

• Register agents on-chain with model hash + capabilities
• Track owner, version, verification status
• Query by model hash, owner, or capability

AgentWallet.sol — Agent Finance

• Each agent has its own on-chain wallet
• ETH + ERC20 support
• Spending policies (per-tx limit, daily limit)
• Approval system for large transactions

AgentMemory.sol — Agent Memory

• On-chain key-value memory storage
• TTL-based expiration
• Memory blocks (chain of committed states)
• Cross-agent memory sharing

AgentReputation.sol — Agent Trust

• Score 0-10000 based on task success/failure
• Staking + slashing mechanism
• Full task history
• Success rate tracking

VerifiableInference.sol — AI Verification

• ZK proof verification for model execution
• Register models with verifier contracts
• Request → Submit Proof → Verify flow
• Cryptographic guarantee of correct inference

AgentCommunication.sol — Agent-to-Agent

• Direct agent messaging
• Conversation tracking
• Skill request/fulfillment protocol
• Encrypted message support

AgentGovernance.sol — Agent DAO

• Create agent fleets (groups of agents)
• On-chain proposals + voting
• Execute arbitrary contract calls
• Delegation system

AgentDeFi.sol — Agent Trading

• Strategy creation + management
• Position tracking (entry price, PnL)
• Trade execution + history
• Yield claiming

Use Cases

1. Autonomous Trading Agents — Agents manage portfolios, execute strategies, claim yield
2. AI Agent Fleets — DAOs govern groups of agents working together
3. Verifiable AI Services — Prove AI ran correctly without revealing the model
4. Agent Marketplaces — Agents hire other agents for skills
5. Cross-Chain Agent Operations — Agents operate across multiple chains via CCIP
