OpenName Review 2026: Omnichain Web3 Domain Names

OpenName is a Web3 domain name service. Its public descriptions say it issues blockchain-based names that work across several networks, using LayerZero to move names between chains. The project also describes a 2.0 version where users can register top-level domains.

The public pages list support for Ethereum, OP Mainnet, Base, Arbitrum, zkSync, BNB Chain, Polygon and Fuse Network, and say more networks are included. A roadmap entry lists a marketplace for domains and top-level domains, though the material reviewed does not confirm whether it is live.

The project does not publish a fee schedule, audit reports or details about its team in the material reviewed. Those gaps matter for a service that holds user names and depends on a cross-chain messaging protocol.

A domain name service maps a human-readable name, such as a word followed by an extension, to an address or other data. On OpenName, the name is recorded on a blockchain and assigned to a wallet. The holder can point the name to a wallet address or other records, so others can send funds or find a profile by typing the name.

OpenName describes itself as an omnichain name service. It uses LayerZero, a messaging protocol that passes information between blockchains, to let a name be moved between supported networks. Each chain keeps its own record, so the holder can control the name on each one. The public material says names can be transferred between chains, but does not explain the exact mechanics of each transfer.

The project's public pages also describe top-level domains, which are the extensions themselves. The 2.0 description says users can register TLDs and earn from them, and the roadmap mentions a marketplace for trading domains and TLDs. Those features depend on the project's ongoing development and on how many people register names.

The project does not publish a fee schedule in the material reviewed. Pricing is mentioned only in general terms: a milestone note describes optimising domain pricing for affordable omnichain services, and a later notice refers to a price adjustment. Users see the actual price and network gas cost at the point of registration, so compare those figures before paying.

Because fees are not stated, the fees score is left blank.

OpenName's names live on blockchains, so holders control them with their own wallets. The project does not publish audit reports for its contracts in the material reviewed, and users should check audit status directly before registering. Cross-chain transfers depend on LayerZero's messaging, so a problem in that protocol or in OpenName's integration could affect transfers.

The material reviewed does not describe any incidents, custody arrangements beyond self-custody, or regulatory status. Users should not assume any protection beyond what the blockchain and wallet provide.

As with any on-chain service, losing a recovery phrase or signing a malicious transaction can cost the name or funds.

OpenName is aimed at people who want one Web3 identity across several blockchains, and at developers or communities interested in registering top-level domains. It is less suited to users who need published pricing, audit reports or a support channel they can verify before committing funds.
