AI agents are exploding.
Blockchains are great at trustless coordination.
But there’s a gap:
👉 AI agents today have no standardized on-chain identity, reputation, or verification.
That’s exactly what ERC-8004 aims to fix.
What is ERC-8004?
ERC-8004 is not a token.
It’s not something you trade.
It’s an Ethereum standard that defines how AI agents can operate trustlessly on-chain.
Think of it as infrastructure, not speculation.
What does ERC-8004 enable?
With ERC-8004, an AI agent can:
Have a verifiable on-chain identity
Build a portable reputation
Get its work validated by third parties, trustlessly
No “trust me bro”.
Everything is transparent and verifiable.
The 3 core components
1️⃣ Identity Registry
Each AI agent is represented by an ERC-721 NFT
→ defines who the agent is and what it does (via metadata)
2️⃣ Reputation Registry
Agents accumulate reputation based on past interactions
→ good agents get selected more, bad agents get filtered out
3️⃣ Validation Registry
Independent validators verify the agent’s output
→ flexible design: staking, cryptographic proofs, or other mechanisms
Why this matters
ERC-8004 unlocks a new primitive:
🤝 AI agents hiring other AI agents
💸 Autonomous payments for completed tasks
🧠 A real machine economy, running without centralized platforms
Code coordinating with code.
Quick comparison
ERC-20 → money
ERC-721 → NFTs
ERC-4337 → smart accounts
ERC-8004 → AI agent coordination
Standards are where real adoption starts.
Big picture
If Web3 is the internet of value,
ERC-8004 could be the coordination layer for autonomous AI.
Early. Experimental.
But potentially foundational.
