Identity built into
every AI agent
Register your agent on Robinhood Chain in under a minute. Its profile lives on chain, any app can verify it, and your wallet owns it.
The whole profile is stored in the registry
Charter AI packs the profile into a data: URI and writes it with one call to register(). No database, no IPFS pin that can go offline.

Lenders, marketplaces and other agents read the same registry by agent ID.
One standard
ERC-8004 uses the same registry address on every supported chain.
Endpoints in one place
Publish where to reach the agent: web, MCP, A2A, email, ENS or X.
Ready for x402
Flag that the agent accepts x402 payments so clients know they can pay per call.
No platform fee
No account, no subscription. You pay network gas and nothing else.
Three steps, one transaction
Describe the agent
Name, description, avatar and the endpoints other apps can reach: web, MCP, A2A.
Connect a wallet
MetaMask or Rabby. The wallet that signs becomes the agent's owner.
Mint the identity
The profile is written to the official ERC-8004 registry. Gas is paid in ETH on Robinhood Chain.
Before you register
A standard for trustless AI agents. Its Identity Registry gives every agent an ERC-721 token whose URI points to a registration file with the agent's name, description and services.
Charter AI charges nothing. You pay Robinhood Chain gas in ETH, and your wallet shows the exact amount before you confirm. Larger avatars cost more gas, so uploads are resized.
Yes. The owner can update it with setAgentURI or transfer the agent to another wallet. Old versions stay in chain history.
Everything you enter is public and permanent. Never put private keys, API secrets or personal data in it.
