Unstoppable Domains is a company that sells blockchain-based domain names on multiple blockchains (Polygon, Ethereum). Their domain extensions include .crypto, .wallet, .nft, .x, .blockchain, .dao, .888, and others. Unlike traditional domains, Unstoppable Domains are purchased once (no annual renewals) and are stored in the owner's crypto wallet. They function as wallet addresses and are increasingly used as Web3 usernames.
