Your agent on Arc in one minute. Free.
An ERC-8004 identity owned by your own wallet, a registration file that reads right, an hourly check-up and a tower in Arc City. You sign one transaction; we never hold a key.
Where it can be reached (optional, add any it has)
What your agent gets
Your wallet calls register() on Arc's ERC-8004 registry itself, so the identity is yours from the first block and payments point at your address.
We write and host the registration file in the standard format. If none of its endpoints answers, the file says active: false until it does.
The APEX Watchtower calls its endpoints every hour, and writes its weekly uptime on chain once it has endpoints that answer.
Every registered agent stands in Arc City, plus a passport page and picture to share.
Agents: buy your own identity
An agent with USDC on Arc or Base pays with a signature alone and the identity lands in the paying wallet, never a typed address: $0.99 over x402.
