Ethereum Name Service (ENS) is a decentralized naming system built on the Ethereum blockchain that transforms complex cryptocurrency addresses into human-readable names. Instead of sharing lengthy hexadecimal strings like 0x71C7656EC7ab88b098defB751B7401B5f6d8976F, you can use a simple ENS domain (e.g., John.eth) linked to your ETH address. ENS also connects wallets, websites, and dApps under a single name, enhancing Web3 accessibility.
How ENS Works
ENS operates through two core Ethereum smart contracts:
ENS Registry:
- Records all registered domain names
- Stores owner addresses, resolvers, and caching time
- Maintains domain ownership records
Resolver:
- Maps ENS names to machine-readable addresses
- Links human-readable names to 42-character public addresses

Step-by-Step Guide to Setting Up ENS on Metamask
1. Create a Metamask Wallet
- Download Metamask from the official site (available as a Chrome extension or mobile app for iOS/Android).
- Set up a new wallet or import an existing one using 12-word seed phrases.
- Secure your wallet with a strong password and backup your recovery phrase.
2. Fund Your Wallet with ETH
- Purchase ETH on exchanges like Coinbase, Binance, or OKX.
- Transfer ETH to your Metamask wallet to cover registration and gas fees (minimum 0.01 ETH recommended).
3. Access ENS Manager
- Visit the ENS Manager via your browser or Metamask’s DApp browser.
4. Search for Your ENS Name
- Type your desired name (e.g.,
yourname.eth) in the search bar. - If available, proceed to registration. If taken, try variations.
5. Request Registration
- Select registration duration (1+ years at ~$5/year).
- Click Connect Wallet and sign the Metamask prompt.
- Tap Request to Register and confirm the transaction.
6. Complete Registration
- Wait 1 minute to ensure no competing requests.
- Click Register, review details, and pay the fee (~$5 + gas).
- Confirm the transaction in Metamask.
7. Link ENS to Your Wallet
- Go to Manage Name > Resolver > Set.
- Paste your Metamask address and click Save.
FAQs
Q: Can I transfer my ENS name to another wallet?
A: Yes! Navigate to ENS Manager, select your domain, and update the owner address under Transfer.
Q: What happens if my ENS registration expires?
A: Others can register the name after a 90-day grace period. Renew anytime via ENS Manager.
Q: Are ENS names case-sensitive?
A: No. YourName.eth and yourname.eth resolve to the same address.
