Unstoppable Domains is a Web3 naming platform and company that issues blockchain-based domain names, such as .crypto and .zil, which users can own and manage directly on a blockchain. Instead of being controlled through a traditional domain registrar and centralized DNS providers, these domains are recorded on-chain, giving the holder control through their crypto wallet.
How blockchain domains work
A blockchain domain functions like a human-readable alias for long wallet addresses and other identifiers. For example, rather than sharing a lengthy hexadecimal address, a user could share a name like “name.crypto” to receive supported cryptocurrencies. The domain’s records are stored on-chain, and the owner can update them by signing transactions with their wallet, similar to managing an NFT. Because ownership is tied to a private key, control is portable across apps that support the standard, and it is not dependent on a single registrar account.
Use cases: payments, identity, and decentralized sites
One of the most common uses is simplifying payments, wallets and exchanges that integrate Unstoppable domains can resolve a domain to the correct address for a given asset. Unstoppable Domains also supports decentralized website hosting by linking a domain to content stored on decentralized storage networks, allowing sites that are more resistant to takedowns than typical web hosting. For developers and partners, Unstoppable provides tooling and APIs that help generate the blockchain transactions needed to set records, manage domains, and integrate resolution into applications.
Unstoppable Domains matters because it reduces friction in crypto transfers, strengthens user-owned identity, and supports a more decentralized web stack where naming and content can be controlled by users rather than centralized intermediaries.
