The Vibe: Your personal “.eth” domain name that replaces long wallet addresses — like a simple, readable username for crypto.
The Details: ENS is a decentralized naming system on Ethereum (and L2s) that lets you register human-readable names (e.g., yourname.eth) linked to your wallet address, website, or other data. Instead of sending to 0xabc…123, you send to friend.eth. Launched in 2017, ENS is now a top NFT project (names are ERC-721 tokens you own forever). In 2026, ENS supports multi-chain (via CCIP), avatars, and integrations with wallets (MetaMask shows ENS names). You buy/renew names via app.ens.domains.
Pro Tip: Get a short .eth name early — they appreciate with adoption. Use ENS for easier payments and branding. Beware fake ENS phishing (always type app.ens.domains manually). Great for identity and reducing wallet errors.
