Own your name. Outright.
Ownership is a naming service built on Arc. A name like yourname.arc is yours — registered on-chain, held in your own wallet, renewable for free, and not rented from a platform that can raise the price or pull the plug.
Arc is a public blockchain built by Circle, the company behind the USDC digital dollar. Ownership is an independent project building on Arc — not a Circle product, and not endorsed by Circle.
You hold your own keys. This site never takes custody of anything: it reads the public contracts to check names, and when you register, your wallet signs the transaction. No accounts, no passwords, no middleman.
Look up a name
Check whether a name is free on the Arc testnet. No wallet needed — this reads the public Registry and Registrar contracts directly.
Participate on testnet
Ownership is live on Arc testnet — come participate: register a name, try the contracts, break things, tell us. Testnet names do not carry over to mainnet — if you want your name there, you will need to register it again when mainnet launches.
How to
Watch the full walkthrough: add Arc Testnet to MetaMask, get testnet USDC from the Circle faucet, connect your wallet, and register your first .arc name — gas sponsored, two-year term, free renewals.
