ERC-8004 — "Trustless Agents" — gives an agent an identity that lives on-chain rather than in a company's database: a registry entry an agent can point at, and that anyone can check without asking permission from whoever built it.
It is early. The registry counts we read from mainnet are real, but a registration proves an entry exists, not that the agent behind it is competent or safe. Treat presence here as identity infrastructure, not endorsement.
ERC: 17 listings, 11 open source and 1 with a commit or release in the last 30 days; top Sato Scores: 0xGasless AgentKit (86), ERC-8004: Trustless Agents (71), Lucid Agents (71), as of 2026-10-15.
Why sources disagree
Each tracker counts a different set of chains and decides what an agent is: every registered id, only ids with a registration file, or testnets too. A wider scope or a looser definition gives a bigger figure, so the figures cannot be lined up or added.

Our own reading is the registry contract's own id counter on each chain, read directly and never summed. ERC-8004 agents by chain →
Figures other trackers publish, quoted with their source and read once a day. They are not Sato Hub's numbers and are never added together; “not read” means we hold no reading, never zero.

Questions people ask about ERC-8004: onchain agent identity
- How many projects implement ERC-8004?
- 17 live listings declare it as of 2026-10-15, spread across api / sdk 6, developer tool 5, agent framework 2, agent launchpad 1. A declaration is recorded from the project's own materials — it is the floor of adoption, not a measurement of it.
- Does declaring ERC-8004 mean it answers?
- No, and the gap is the point. Declaring costs nothing: a tag, a manifest line, a sentence in a README. Whether an endpoint actually responds is measured separately by daily checks, published per listing, and never folded into this count.
- Where is ERC-8004 defined?
- In the standard's own documents, not here: EIP-8004 at https://eips.ethereum.org/EIPS/eip-8004. Sato Hub records which listings implement it and what our checks observed; it does not author the standard and does not certify conformance.
- Are these implementations verified?
- Not by implementing the standard. 17 of the 17 carry a Sato Score — a 0–100 reading of how open, active and verifiable a project is — and 8 publish an install manifest. Neither is an audit, a security review, or a conformance certificate.
- Which of these are open source?
- 11 of 17: 0xGasless AgentKit, ERC-8004: Trustless Agents, Lucid Agents, Emblem Agent Skills, ERC-8183: Agentic Commerce, Agently, Pinata ERC-8004, ChaosChain, ERC-8126: AI Agent Verification, Agent0 SDK, create-8004-agent.
- Which are actively maintained?
- 1 had a commit or release in the last 30 days: 0xGasless AgentKit. Posts on X do not count. Activity is a recency signal, not a quality judgment.
- Which have an earned verification on Sato Hub?
- 9: 0xGasless AgentKit, ERC-8004: Trustless Agents, Lucid Agents, Emblem Agent Skills, ERC-8183: Agentic Commerce, Agently, ERC-8126: AI Agent Verification, Sato OS, 0xWork. An earned check is named as what was checked (install reproduced, endpoint probed, on-chain identity read, reviewed against evidence); none is a safety claim.
- Which run as MCP servers?
- 4: Lucid Agents, Emblem Agent Skills, Agently, Injective Agents.
- How is this list ranked?
- ERC is derived from Sato Hub's live records by a stated rule and ordered by Sato Score, a 0–100 measure of how open, active and verifiable each project is. It is not a quality ranking and declares no winner.
