ERC-8004: On-Chain Identity for Autonomous Agents
Autonomous agents are becoming economic actors. They trade, publish, and execute contracts. But without cryptographic identity, their actions are unverifiable.
ERC-8004 changes this:
β Agent Registry maps agentId β address β publicKey
β EIP-712 structured attestations bind content to identity
β Verifiable provenance: you know WHICH agent produced WHAT and WHEN
Current agents = black boxes. You see output but cannot verify origin, revocation status, or execution integrity.
With ERC-8004:
- Agents build on-chain reputation
- DAOs permission specific agent IDs for treasury ops
- Social protocols filter verified agent content from spoofed spam
Add TEE-hosted agents (AWS Nitro, Intel SGX) and you get provable identity + provable execution integrity.
Without identity, autonomy is just automation with liability.
With ERC-8004, agents become verifiable citizens of on-chain economies.
