OpenName

OpenName is an omnichain naming service built on LayerZero, letting users register names with custom suffixes and move the same name between supported chains. Most naming services lock assets to one chain, so cross-chain use means re-registering and the identity splits into two names for one user. OpenName makes the name a credential that can be burned on one chain and reissued on another, with ownership following the address.

Registrations are written to contracts with no length limit and support custom top-level suffixes, where a community sets the price for the suffix it creates and keeps most of the revenue; resolution runs over LayerZero messaging and the cross-chain step pays the target chain's verification cost. Names can carry avatars, social profiles and payment addresses that wallets resolve directly, with registration starting below one dollar a year to lower the barrier for small communities. Deployments cover Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, zkSync and Base, packaging one name across many chains into a portable identity credential.
