Terms of Use
These terms describe the basis on which the independent ArcNS app is made available on Arc. They are informational project terms and are not legal advice.
Last updated: September 13, 2026
Network and service status
ArcNS uses public blockchain infrastructure. Transactions are irreversible; users should verify the network, recipient, price, contract addresses, and wallet prompts before signing.
No promises or professional advice
ArcNS is provided on an experimental, as-is, and as-available basis. Nothing in the app or documentation is a promise of financial return, continued availability, legal outcome, or fitness for a particular purpose. ArcNS does not provide financial, investment, tax, or legal advice.
Name registration and renewal
Names are ERC-721 NFTs with registration periods and renewal requirements. Registration expires unless renewed before the applicable expiry date.
Users are responsible for checking the selected registration period, applicable expiry date, renewal status, wallet transactions, and network conditions. Records created in a different deployment do not automatically transfer to Arc mainnet.
Independent project and trademarks
ArcNS is an independently developed and operated naming protocol built on Arc. ArcNS is not an official Arc or Circle product and is not operated by, affiliated with, sponsored by, or endorsed by Circle or the Arc team. The word ‘Arc’ in the ArcNS name identifies the network on which the protocol is built; it does not indicate ownership, authorization, or official status. Arc and Circle are trademarks of Circle Internet Group, Inc. and/or its affiliates. No rights in those marks are claimed.
The .circle namespace is offered by the independent ArcNS protocol. Its name does not imply that Circle owns, operates, authorizes, sponsors, or endorses the namespace.
