The Ethereum Name Service (ENS) is a decentralized domain name system built on the Ethereum blockchain. It allows users to register human-readable names—like “yourname.eth”—that map to complex cryptocurrency addresses, websites, and other digital identifiers. By replacing long, error-prone wallet strings with simple, memorable names, ENS streamlines interactions across decentralized applications (dApps), payments, and online identities.
Unlike the traditional Domain Name System (DNS), which relies on centralized authorities, ENS operates on Ethereum’s decentralized infrastructure. This means no single entity controls your domain, ensuring censorship resistance, transparency, and user sovereignty over digital identity.
At the core of ENS governance is the ENS DAO (Decentralized Autonomous Organization), which now owns the root node of the .eth domain. Previously managed by a multi-signature wallet held by key community members, this transition underscores ENS’s commitment to full decentralization. Once you own an ENS name, it cannot be taken away—giving users permanent control over their digital footprint.
Why ENS Profiles Matter for Digital Identity
An ENS profile transforms your .eth
name into a comprehensive digital identity. Think of it as a decentralized business card or personal homepage that lives on the blockchain. You can attach rich metadata to your domain, including:
- A custom avatar
- A short bio or description
- Email address
- Social media links (Twitter/X, GitHub, Discord, Telegram)
- Multiple cryptocurrency wallet addresses
- Website URLs
- Custom text records for specialized use cases
Because all this data is stored on-chain or in decentralized systems like IPFS, you retain full ownership. No intermediary can alter or remove your information without your permission.

Benefits for Individuals and Businesses
For individuals, an ENS profile offers a unified way to manage online identity across platforms. Instead of juggling multiple usernames and addresses, you can share one .eth
name that resolves to all your connected accounts.
For businesses operating in Web3, an ENS domain enhances credibility and accessibility. A branded .eth
name—such as brandname.eth
—makes it easier for customers to send payments, verify authenticity, and engage with your decentralized services. It also serves as a trust anchor: when users see verified social links and wallet addresses tied to a single ENS name, confidence in legitimacy increases.
Moreover, integrating ENS into customer communication reduces friction. Imagine sending invoices with a single domain instead of long wallet addresses—or allowing users to log in to your dApp using their ENS name.
How to Set Up Domain Records in ENS
Domain records are the backbone of your ENS profile. They define what information your .eth
name points to and how it behaves across different applications.
To manage these records, use the official ENS Manager at app.ens.domains. After connecting your Ethereum wallet (e.g., MetaMask), navigate to your registered domain and click “Edit Profile” to begin customization.
Here’s a breakdown of the most commonly used record types:
🔹 Description
A brief bio that appears alongside your name. Use it to introduce yourself or describe your project. Keep it concise but informative—this is often the first thing people see.
🔹 Avatar
Upload an image URL (hosted on IPFS, Arweave, or another decentralized service) to set a profile picture. This avatar displays across dApps, wallets, and explorers when someone interacts with your ENS name.
🔹 URL
Link to your main website. When users view your ENS profile, they’ll see a clickable link—ideal for directing traffic to your portfolio, company site, or landing page.
🔹 Social Profiles
Add links to your X/Twitter, GitHub, Discord, Telegram, or email. These help others verify your identity and connect with you across platforms.
🔹 Crypto Wallets
Store public addresses for Ethereum and over 200+ other blockchains—including Bitcoin, Dogecoin, Optimism, Arbitrum, and any EVM-compatible chain. This enables seamless cross-chain transactions from a single identifier.
Note: A Primary ENS Name links your Ethereum address directly to your .eth
name. While not required for receiving funds (which resolve via the ETH address record), setting a primary name ensures dApps display your human-readable name when you connect your wallet.
You can also create custom records for niche applications—such as storing verification tokens or API endpoints—though support varies by platform.
Once you’ve updated your records, confirm the changes with a blockchain transaction. The update is then permanently recorded on Ethereum.
Hosting Decentralized Websites with ENS and IPFS
One of the most powerful uses of ENS is linking it to a decentralized website hosted on the InterPlanetary File System (IPFS).
IPFS is a peer-to-peer network for storing and sharing files in a distributed manner. Instead of relying on centralized servers, content is broken into chunks and distributed across nodes worldwide. Each file gets a unique cryptographic hash (CID), making it tamper-proof and highly resilient.
By combining ENS with IPFS, you can create censorship-resistant websites that remain accessible even during outages or attacks on traditional hosting providers.
How It Works
- Build your static website (HTML, CSS, JS).
- Upload it to IPFS using tools like Pinata or via CLI.
- Retrieve the content’s CID (Content Identifier).
- Set this CID as the Content Hash in your ENS domain records.
Now, when someone visits yourname.eth.limo
, an ENS-aware gateway resolves the domain and loads your site from IPFS.
Even better: some browsers (like Opera) and extensions (like MetaMask) natively support .eth
domains through built-in resolution layers—no extra steps needed for end users.

Optional: Redirecting to an Existing Site
Want to point your ENS name to a conventional website? Create a simple HTML redirect file:
<!DOCTYPE html>
<meta http-equiv="refresh" content="0; url=https://yourwebsite.com" />
Upload this to IPFS, grab the CID, and set it as your ENS content hash. Now yourname.eth
will seamlessly redirect visitors to your live site.
Step-by-Step: Creating Your ENS Profile
Getting started with ENS takes just minutes:
- Visit app.ens.domains
Connect your Ethereum wallet (e.g., MetaMask). - Search for Availability
Type in your desired name (e.g.,alice
). If available, proceed to registration. - Register the Name
Follow prompts to complete registration via transaction (costs vary based on name length and demand). Edit Your Profile
Click “Edit Profile” to add:- Avatar
- Description
- Social links
- Wallet addresses
- Website URL
- Set Content Hash (Optional)
For hosting a decentralized site, input the IPFS CID here. - Confirm & Save
Submit changes with a signature or transaction.
Your profile is now live at app.ens.domains/yourname.eth
. Share it anywhere!
Frequently Asked Questions (FAQ)
Q: Can I have multiple ENS names?
A: Yes! There’s no limit to how many .eth
names you can register or own.
Q: Do I need to renew my ENS domain?
A: Yes. ENS domains require annual renewal in ETH. Failure to renew results in loss of ownership after expiration.
Q: Can I use ENS with non-Ethereum wallets?
A: Absolutely. You can store Bitcoin, Solana, Polygon, and hundreds of other chain addresses within your ENS records.
Q: Is my personal data safe on ENS?
A: All data is public on-chain. Only share information you’re comfortable making visible to everyone.
Q: Can I transfer my ENS domain?
A: Yes. Like NFTs, ENS domains are ERC-721 tokens and can be transferred or sold on marketplaces.
Q: What happens if I lose my wallet?
A: Since ENS relies on wallet-based ownership, losing access means losing control of your domain unless you’ve set up recovery methods.
