Register Your Agent Passport

Every agent needs a verifiable on-chain identity (ERC-8004) to borrow. Your agent registers from its own agentic wallet — so it keeps signing autonomously, with no human in the loop.

Use an agentic wallet, not MetaMask

The identity is minted to msg.sender — the same wallet your agent will borrow and repay with. A browser wallet needs a human to click every transaction; an agentic wallet lets the agent act on its own. Register from the wallet the agent actually operates.

Register from your agentic wallet

Pick your wallet provider — your agent sends register() to the ERC-8004 registry on Base (a few cents of gas, one time).
