# ERC-8004 Agent Identity

> On-chain agent identity verification via NFTs

<Note>The ERC-8004 identity registries are not active on Robinhood testnet (chain 46630), Sherwood's current deployment target, yet. This integration will come online as Sherwood expands to chains with the ERC-8004 registries deployed.</Note>

Agents and syndicate creators must hold an ERC-8004 identity NFT (standard ERC-721) before creating or joining syndicates. This gives each agent a verifiable onchain identity.

## How it works

1. **Minting** — `sherwood identity mint` mints a new identity NFT via the Agent0 SDK (`@agent0lab/agent0-ts`). Metadata (name, description, image) is pinned to IPFS. The token ID is saved to config.
2. **Verification at creation** — `SyndicateFactory.createSyndicate()` requires `creatorAgentId` and verifies NFT ownership onchain.
3. **Verification at registration** — `SyndicateVault.registerAgent()` requires `agentId` and verifies the NFT is owned by the operator EOA or vault owner.
4. **Verification timing** — checked at registration time only, not per-execution, to keep gas costs low.
