What is Unstoppable Domains Service
Unstoppable Domains is a service that provides NFT-based domain names for the decentralized web. This guide explains how it works, its features, and how.

Unstoppable Domains provides blockchain-based domain names designed for the decentralized web. This service aims to replace long, complex cryptocurrency wallet addresses with human-readable alternatives. Unlike the Ethereum Name Service (ENS), which primarily offers .eth domains, Unstoppable Domains supports a broader selection of domain endings, including .crypto, .x, .wallet, .nft, and .blockchain. These domains operate outside the traditional Domain Name System (DNS) and are registered as NFTs on a public blockchain, typically Polygon.
Key Features of Unstoppable Domains
-
One-Time Purchase, No Renewal Fees: When you acquire an Unstoppable Domain, you own it indefinitely. Unlike ENS, which requires annual renewal fees, Unstoppable Domains charges a one-time registration fee. The NFT representing your domain remains under your control permanently.
-
Universal Username for Web3: An Unstoppable Domain serves as a central hub for your digital identity. You can link multiple cryptocurrency addresses to a single domain. This simplifies transactions; when someone wants to send you cryptocurrency, they can enter
yourname.cryptointo a supported wallet, which will automatically retrieve the correct address for their specific currency. -
Decentralized Websites: You can create a censorship-resistant website using your Unstoppable Domain. These sites are typically hosted on decentralized storage networks like the InterPlanetary File System (IPFS). This structure prevents any single company from taking down your website.
-
Login to dApps: An increasing number of decentralized applications (dApps) now integrate Unstoppable Domains for authentication. This feature allows users to use their domain as a universal identity across the Web3 ecosystem.
How Does it Work?
-
NFT-Based Ownership: Purchasing a domain involves minting an NFT on the Polygon blockchain. This NFT resides in your personal crypto wallet, granting you full custody and control.
-
Managing Records: You can manage your domain's records (for example, the cryptocurrency addresses it points to) via the Unstoppable Domains website or directly through the smart contract. Each change corresponds to a transaction on the Polygon network.
