A web3 domain is a blockchain-based name that replaces your long, complicated crypto wallet address with something short and readable — like "yourname.crypto" or "alice.eth."
Think of it as a .com for the decentralized internet, except you actually own it.
Traditional domains are rented — you pay annually to a central registrar, and if you stop paying or break their rules, your domain disappears.
Web3 domains work differently: once you register one, it's minted as an NFT directly into your crypto wallet.
Nobody can revoke it, censor it, or take it away — not even the platform that sold it to you.
Beyond replacing wallet addresses, web3 domain names can serve as your universal login across decentralized apps, power decentralized websites, and handle crypto payments in any currency.
That combination of permanent ownership and real utility is what's driven millions of registrations since the web3 domain market first emerged in 2017.
Background of Web3 Domains
The internet's existing naming system — the Domain Name System (DNS) — works like a giant phone book, translating website names into the IP addresses your browser needs to connect.
But DNS is controlled by centralized authorities, which creates real vulnerabilities: domain hijacking, DNS spoofing, and outright government-ordered seizures are all possible when a handful of organizations control the system.
Blockchain technology changed that equation.
By recording domain ownership directly on a public blockchain — secured by cryptography and enforced by smart contracts — web3 domains remove the need for any central authority to maintain or validate your claim to a name.
That decentralized structure is what makes web3 domains censorship-resistant and tamper-proof by design.
Use Cases and Functions
Web3 domains support a range of practical use cases that make blockchain services significantly easier to navigate:
- Crypto Wallet Addresses: Replace long, error-prone wallet addresses with a simple name — anyone sending you crypto types "yourname.crypto" instead of a 42-character hex string.
- Digital Identity: Use your domain as a consistent username and profile across Web3 platforms and decentralized applications.
- Decentralized Websites: Point your domain to content hosted on IPFS, the decentralized storage network, to publish websites that no single server controls.
- Permissionless Payments: Send and receive any cryptocurrency without going through a payment processor or financial intermediary.
- Web3 Login: Log into dApps and blockchain platforms using your domain as your credential, without relying on Google, Apple, or any third-party identity provider.
What Are Web3 Domain Extensions?
Just like traditional websites end in .com or .org, web3 domains have their own set of extensions — and the list keeps growing.
Each extension is tied to a specific blockchain or platform, and they vary in pricing structure, ecosystem support, and whether you'll pay annually or just once.
Here are the most widely recognized web3 domain extensions available today:
Extension | Platform | Blockchain | Renewal Required? |
.eth | Ethereum Name Service (ENS) | Ethereum | Yes (annual) |
.crypto | Unstoppable Domains | Polygon / Ethereum | No |
.nft | Unstoppable Domains | Polygon / Ethereum | No |
.wallet | Unstoppable Domains | Polygon / Ethereum | No |
.x | Unstoppable Domains | Polygon / Ethereum | No |
.dao | Unstoppable Domains | Polygon / Ethereum | No |
.blockchain | Unstoppable Domains | Polygon / Ethereum | No |
.bitcoin | Unstoppable Domains | Polygon / Ethereum | No |
.888 | Unstoppable Domains | Polygon / Ethereum | No |
.bnb | Space ID | BNB Chain | No |
.arb | Space ID | Arbitrum | No |
.xdc | XDC Web3 Domains | XDC Network | No |
The .eth extension, managed by the Ethereum Name Service, is the most widely integrated option — supported across more wallets and dApps than any other naming standard.
Unstoppable Domains controls the broadest extension catalog and continues to add new ones: in November 2025, it launched .spend and .amped in partnership with Amp, both designed for real-world crypto payment use cases.
For maximum ecosystem compatibility, .eth and .crypto are the two most widely recognized choices — though .eth requires an annual renewal fee while .crypto is a one-time purchase.
What Are the Benefits of Owning a Web3 Domain?
The main purpose of a web3 domain is to give you permanent, self-sovereign ownership of your digital identity — without relying on any central authority to keep it active.
That's a fundamental shift from how the traditional internet works, and it comes with several practical advantages.
No more confusing wallet addresses.
Sending crypto to a 42-character wallet address is one of the biggest friction points for everyday users.
A web3 domain maps that address to "john.crypto," and anyone sending funds just types the name instead — cutting down on errors and making crypto far more accessible to beginners.
You own it like an asset, not a subscription.
Most web3 domains — excluding .eth — are sold as one-time purchases with no annual renewal fees.
Because they're minted as NFTs, your domain lives in your wallet and can be held, sold, or transferred just like any other on-chain asset.
Censorship resistance.
No government, registrar, or corporation can revoke your web3 domain.
Traditional domains can be suspended or seized by ICANN-authorized registrars under legal orders — web3 domains are governed by smart contracts that no single party controls.
One identity across the Web3 ecosystem.
Brave Browser, MetaMask, Trust Wallet, Crypto.com, and Blockchain.com all recognize web3 domain names.
Register one and it can function as your payment address, your decentralized website, and your Web3 login — all from a single name.
Popular Web3 Domain Platforms
Several platforms let you register a web3 domain today, each operating on different blockchains with different extension sets and pricing models.
Ethereum Name Service (ENS)
It issues .eth domains stored as NFTs on Ethereum mainnet, and is supported across more wallets and dApps than any competing naming standard.
Over 2 million .eth domain names have been registered on-chain, and ENS is actively developing ENSv2 — a Layer 2 upgrade designed to slash gas costs and enable seamless cross-chain domain resolution.
Pricing starts at around $5 per year for five-character-or-longer names, similar to traditional domain registrars.
Official site: https://ens.domains
Unstoppable Domains
Unstoppable Domains is the largest web3 domain registrar by extension count, with over 4 million domains registered across .crypto, .nft, .wallet, .x, .dao, .blockchain, .bitcoin, .888, and more.
Most of its domains are one-time purchases — no annual renewal fee after the initial payment.
The platform received ICANN accreditation in October 2024 and is supported across hundreds of applications, including Brave Browser, MetaMask, Trust Wallet, Crypto.com, and Blockchain.com.
Official site: https://unstoppabledomains.com
Space ID
Space ID offers .bnb domains on BNB Chain and .arb domains on Arbitrum, both at a flat $5 per year.
It's a popular choice for developers building in the BNB and Arbitrum ecosystems, thanks to its Web3 Name SDK and API that simplifies domain integration into decentralized applications.
Official site: https://space.id
XDC Web3 Domains
XDC Web3 Domains issues .xdc names on the XDC Network — an EVM-compatible blockchain focused on enterprise trade finance and real-world asset tokenization.
Each .xdc domain is minted as an XRC721 NFT and can store multiple wallet addresses — BTC, ETH, Solana, and others — under a single human-readable name.
Official site: https://xdcdomains.xyz
Freename
Freename is a multi-chain registrar with a standout feature: users can create and own their own custom top-level domains and earn a 50% commission on every domain registered under their extension.
It supports no-renewal web3 domains across multiple blockchains and offers a Web3 WHOIS lookup tool covering Freename, Unstoppable Domains, and ENS.

How to Buy a Web3 Domain
Buying a web3 domain takes about 10 minutes if you already have a crypto wallet set up.
The process is consistent across most platforms: pick a name, connect your wallet, pay, and the domain is minted directly to you.
Step 1: Set up a crypto wallet.
You'll need a Web3 wallet to receive and store your domain once registered.
MetaMask is the most widely compatible option, available as a browser extension or mobile app.
Fund it with ETH for ENS, or ETH and MATIC for Unstoppable Domains, depending on which blockchain you're minting on.
Step 2: Search for your name.
Go to your chosen platform's website and type in the name you want — the process works exactly like searching for a .com on a traditional registrar.
If the name is taken, most platforms suggest available alternatives.
Step 3: Complete the purchase.
ENS charges an annual fee in ETH plus a gas fee at the time of registration.
Unstoppable Domains accepts credit cards, PayPal, and crypto, and covers gas fees for domains minted on Polygon — which covers most of its extensions.
Step 4: Mint your domain.
After payment, your domain is minted as an NFT and transferred to your wallet automatically.
ENS mints on Ethereum mainnet; Unstoppable Domains mints most extensions on Polygon.
Step 5: Set up your records.
Link your crypto wallet addresses, point the domain to a decentralized website, or configure it as your Web3 login.
ENS supports an Ethereum address, IPFS content hash, and social metadata; Unstoppable Domains supports over 300 cryptocurrencies and lets you build a public profile page showcasing your NFTs and on-chain activity.
Can You Get a Free Web3 Domain?
Free web3 domains exist, but they typically come through limited-time promotions rather than being the standard model.
ENS has run campaigns where users can claim .eth names for up to five years at no cost, usually tied to Layer 2 ecosystem integrations or community events.
Platforms like Freename occasionally offer zero-cost registrations during new TLD launch windows, and some newer blockchain networks run free mint campaigns to attract early adopters.
The catch: even "free" domains usually require a small gas fee to record ownership on-chain, so you'll still need a bit of cryptocurrency in your wallet.
Impact on the Market, Technology or Investment Landscape
The rise of web3 domains has created a real shift in how the broader internet industry views blockchain-based ownership.
The clearest signal came in October 2024, when Unstoppable Domains received ICANN accreditation — becoming one of the first blockchain-native domain companies to gain formal recognition within the traditional internet governance structure.
That milestone matters because ICANN accreditation is the credential required to sell conventional domains like .com and .net, meaning Unstoppable Domains now operates across both the traditional web and the decentralized web simultaneously.
On the technology side, Ethereum Name Service is deploying ENSv2 on Ethereum L1 — an upgrade that introduces single-step name registration, stablecoin payment support, and a new hierarchical registry model that gives every .eth name its own on-chain registry.
For investors, web3 domains represent a distinct asset class: verifiable on-chain ownership, a finite supply of desirable names, and an expanding set of real-world applications across wallets, browsers, and decentralized services.
Latest Trends and Innovations
The web3 domain space is scaling fast on two parallel fronts: raw registration volume and mainstream integration.
The major platforms have collectively logged millions of registrations since 2021, with the pace of adoption picking up alongside broader Web3 growth.
Platform | Domains Registered | Notable Development |
Ethereum Name Service (ENS) | 2M+ on-chain | ENSv2 on Ethereum L1; App Alpha live on Sepolia testnet (Feb 2026) |
Unstoppable Domains | 4.6M+ across extensions | ICANN-accredited registrar; pursuing .brave, .blockchain in 2026 gTLD round |
Space ID | — | .bnb on BNB Chain and .arb on Arbitrum |
XDC Web3 Domains | — | .xdc on XDC Network for enterprise use cases |
On the integration side, Brave Browser now natively resolve select web3 domains without any plugins or browser extensions.
Unstoppable Domains is also pursuing ICANN approval for several of its TLDs — including .brave — in the upcoming 2026 gTLD round, which would give those extensions full DNS compatibility alongside their existing on-chain benefits.
Usage on the MEXC Platform
On the MEXC platform, users can link a web3 domain name directly to their crypto wallet address, replacing the long alphanumeric string with something easy to share and verify.
This is especially useful when receiving payments from other users — instead of copying and double-checking a 42-character address, you send them "yourname.crypto" and the funds route automatically.
To get started, register a domain through any of the platforms listed above, then configure it to point to your MEXC wallet address in the domain's record settings.
