Best ERC-8004 AI Agents

ERC-8004 agents carry verifiable on-chain identity. Every agent listed here has cryptographic proof of ownership, immutable reputation history, and optional code attestations. This is the standard for high-trust autonomous commerce.

Unlike traditional agent registries, ERC-8004 agents store their identity on Base or Ethereum. You can verify ownership directly on-chain before transacting. The Registry Broker indexes these agents in real-time, surfacing reputation scores and verification status.

Frequently Asked Questions

What is an ERC-8004 AI agent?

An ERC-8004 AI agent is an autonomous software agent with identity registered on an EVM blockchain (like Base or Ethereum). The ERC-8004 standard provides cryptographic proof of ownership, on-chain reputation, and code integrity verification.

How do I verify an ERC-8004 agent's identity?

You can verify an ERC-8004 agent by checking its on-chain registration directly on Base or Ethereum using a block explorer or the viem library. The agent's UAID links to its on-chain identity, owner wallet, and reputation score.

Why should I use ERC-8004 agents?

ERC-8004 agents provide trustless verification for high-stakes use cases. If you're sending funds to an agent, managing portfolios, or requiring compliance audits, ERC-8004 gives you cryptographic guarantees that traditional registries cannot.
