The Ethereum Name Service (ENS) has emerged as a cornerstone of Web3 identity, offering users a decentralized and human-readable alternative to complex cryptocurrency addresses. If you've ever struggled to remember or share a long string of alphanumeric characters for your Ethereum wallet, ENS provides an elegant solution with .eth domains. This guide walks you through the complete process of registering and configuring your own ENS domain—securely, efficiently, and with full control over your digital identity.
Understanding ENS: The Decentralized Alternative to DNS
The traditional Domain Name System (DNS) acts as the internet’s phonebook, translating domain names like example.com into IP addresses. However, DNS is centralized, meaning domain registrars or authorities can suspend or seize domains. In contrast, the Ethereum Name Service (ENS) operates on the Ethereum blockchain, giving users full ownership and censorship-resistant control over their digital identities.
An ENS name—such as yourname.eth—functions like a universal username across Web3. It can store multiple cryptocurrency addresses (Bitcoin, Ethereum, Litecoin, etc.), link to decentralized websites hosted on IPFS, and even display social media profiles. Importantly, every ENS domain is an ERC-721 non-fungible token (NFT), making it tradable on NFT marketplaces and verifiably unique.
While early adoption focused on .eth domains, ENS now supports integration with existing DNS domains (like .xyz or .art) through DNSSEC validation. This allows owners of traditional domains to bridge them into the decentralized ecosystem.

Setting Up Your Ethereum Wallet
Before registering an ENS domain, you need a self-custodial Ethereum wallet with enough ETH to cover registration and gas fees. MetaMask is the most widely used option due to its browser extension and mobile app compatibility.
Step-by-Step Wallet Setup:
- Download MetaMask from the official site.
- Create a new wallet and securely back up your seed phrase—this is critical for recovery.
- Never share your private key or seed phrase with anyone.
Once set up, fund your wallet:
- Transfer ETH from another wallet or exchange (e.g., Coinbase, Binance).
- Use a credit card via integrated on-ramps within MetaMask (available in supported regions).
Ensure you have at least 0.05–0.1 ETH to cover both the annual registration fee ($5 in ETH for 5+ character names) and variable gas costs, which can fluctuate significantly depending on network congestion.
Registering Your ENS Domain
With your wallet ready, visit the official ENS App—the primary interface for domain registration and management.
1. Search for Availability
Enter your desired .eth name in the search bar. The app will display whether it's available and show the yearly cost in ETH.
Note: Shorter names (3–4 characters) are premium-priced and auction-based, while standard 5+ character names are fixed at $5/year.
2. Start Registration
Click “Request to Register” and connect your MetaMask wallet. You’ll initiate two transactions:
- Commitment Transaction: Registers your intent privately to prevent front-running.
- Finalization Transaction: Completes the registration after a short delay (usually one minute).
Confirm both transactions in MetaMask. Due to Ethereum gas fees, total cost may exceed $50 during peak times—plan accordingly.
3. Set Reverse Record
After registration, configure the reverse record so your Ethereum address resolves back to your ENS name. This ensures that when someone looks up your wallet address in a dApp or wallet interface, your .eth name appears instead of a random string.
To set this:
- Go to your profile in the ENS app.
- Click “Set Reverse Record.”
- Select your domain and save, confirming the final transaction.
Now, your identity is fully linked across the Ethereum ecosystem.

Key ENS Domain Attributes Explained
Understanding these core components helps you manage your domain effectively:
- Registrant: The owner of the domain who can transfer ownership or update settings.
- Controller: The account authorized to manage the domain (often the same as the registrant).
- Expiration Date: Renewals are required annually; there’s a 90-day grace period post-expiry before the domain becomes available again.
- Resolver: A smart contract that translates ENS names into blockchain-readable data. The default is the public resolver maintained by ENS.
- Records: Customizable fields where you store crypto addresses, content hashes (e.g., for IPFS-hosted sites), texts (like email or Twitter), and more.
You can edit records at any time by clicking “Add/Edit Record” and signing a transaction via MetaMask.
Advanced Uses of ENS Domains
Beyond simplifying wallet addresses, ENS enables powerful decentralized applications:
Create Subdomains
You can generate subdomains like pay.me.eth or blog.yourname.eth, each with separate controllers and records. These inherit ownership from the parent domain but allow granular delegation—ideal for teams or multi-service setups.
Link to Decentralized Websites
Pair your ENS domain with an IPFS-hosted site by setting the contenthash record. This creates a censorship-resistant website accessible via browsers with IPFS gateways.
Integrate With dApps and Wallets
Most major wallets (MetaMask, Rainbow, Argent) and decentralized apps automatically recognize ENS names. Sending funds becomes as easy as typing alice.eth instead of a 42-character address.
Frequently Asked Questions (FAQ)
Q: How much does an ENS domain cost?
A: For 5+ character names, it's $5 per year in ETH. Shorter domains cost more due to higher demand and are sold through auctions.
Q: Can I sell my ENS domain?
A: Yes—since ENS domains are NFTs (ERC-721), they can be listed on NFT marketplaces like OpenSea.
Q: Do ENS domains expire?
A: Yes. You must renew annually. After expiration, you have a 90-day grace period before losing ownership.
Q: Is ENS only for Ethereum addresses?
A: No. You can store addresses for over 80 cryptocurrencies, including Bitcoin, Dogecoin, and Litecoin.
Q: Can I use my ENS domain as a website URL?
A: Yes, if you host content on IPFS or Swarm and set the appropriate content hash in your records.
Q: Are ENS domains censorship-resistant?
A: Yes. Once registered, no central authority can take down or alter your domain without access to your wallet.

Final Thoughts
Registering an ENS domain is more than just securing a memorable name—it's about claiming sovereignty over your digital identity in Web3. From simplifying transactions to enabling decentralized websites and cross-chain interoperability, ENS empowers users with true ownership and long-term utility.
As blockchain adoption grows, having a .eth domain may become as standard as owning a personal email address. Whether you're a developer, investor, or casual user, now is the ideal time to register yours.
