How to Register an ENS Crypto Domain

A step-by-step guide to registering an Ethereum Name Service (ENS) domain (.eth), the decentralized alternative to traditional DNS for the Web3 era.

What Is ENS?

The Ethereum Name Service (ENS) is a blockchain-based naming system built on Ethereum. It maps human-readable names (e.g., yourname.eth) to:

Cryptocurrency addresses (ETH, BTC, DOGE).
Decentralized website content (IPFS hashes).
Social media profiles.

ENS domains are ERC-721 NFTs, making them tradable on platforms like OpenSea.

Key Features:

Decentralized: No central authority can seize domains.
Multi-chain: Supports addresses for Bitcoin, Litecoin, and more.
Customizable: Subdomains and record management.

Step 1: Set Up an Ethereum Wallet

Download MetaMask:
- Install the MetaMask browser extension.
- Secure your seed phrase and private key (never share these!).
Fund Your Wallet:
- Buy ETH via exchanges like Coinbase or Binance.
- Transfer ETH to your MetaMask address.

Step 2: Register an ENS Domain

Visit the ENS App:
- Go to app.ens.domains.
- Search for your desired .eth name (e.g., yourname.eth).
Complete Registration:
- Pay the annual fee (~$5 in ETH + gas fees).
- Extend registration to avoid yearly gas costs.
Configure Records:
- Set a reverse record (link your ETH address to the domain).
- Add cryptocurrency addresses or IPFS hashes under Records.
