Leading Blockchain Domains Providers

Not all cryptocurrencies support blockchain domain systems. Only a few blockchains are technically suited for this use, mainly those that allow smart contracts.
The most widely used technology is ENS (Ethereum Name Service), with .eth domains that act as decentralized identifiers, replacing wallet addresses and integrating across the Ethereum ecosystem.

Unstoppable Domains is the second major player, offering multiple extensions across various blockchains. It has taken advantage of the hype surrounding cryptocurrencies and web3 to sell via aggressive marketing domain names with sparkling extensions such as .BITCOIN, .X, .CRYPTO, .NFT or .888, but not interoperable with the global DNS and which lack practical use.

Challengers in the blockchain domains sector include Space ID, which enables cross-chain domains like .bnb and .arb, sns.sol for Solana-based .sol domains, RNS on the Bitcoin sidechain RSK, Tezos domains for the Tezos blockchain, Peername, focusing on early or alternative blockchain naming systems and Orange Domains, a joint-venture including Tucows.

Top level Web3 Domains

Some Web3 providers allow users to create their own TLDs, especially Namebase and Bob Wallet, which operate on the Handshake blockchain. SPACE ID also offers this service on BNB Chain, Arbitrum, and Ethereum. Other players like Freename, Decentraweb, and Pool Infinity Domains also enable the sale of both Web3 top-level domains and second-level domains.

NameStone provides an API for seamless, gasless management and issuance of Ethereum Name Service (ENS) subdomains.

Web 2.5

U.S.-based company founded by Fred Hsu in 2023, D3 Global is a pioneer in the Web 2.5 space. Thanks to partnerships with major blockchains and registrars and participation in nTLD ICANN round 2 in 2026, D3 plans to launch ICANN-approved, blockchain-native TLDs and build an on-chain marketplace for legacy Web2 domains.
Similar Web 2.5 projects, albeit on a smaller scale, are currently being carried out by start-ups such as 3DNS, NameFi and WebUnited.

Other Web3 Players

GBM Domains allows to tokenize, trade and manage DNS domains.

FIO Protocol is a decentralized identity project that allows users to create a single, human-readable FIO address (like jane@wallet) that links to all their crypto wallets.

XPR Network is a layer-one blockchain that offers fast, gas-free transactions, on-chain identity, and WebAssembly smart contracts.

VM.COM is a NFT marketplace for traditional domain names.
