Blockchain technology has revolutionized how we think about ownership, identity, and digital transactions. Yet one persistent challenge remains: the complexity of cryptocurrency wallet addresses. Imagine sending funds using a long string like 0x0212Cbf11e23879aE0681dB7E2c6A38eE986D0d — difficult to remember, easy to mistype, and risky to share. This is where Ethereum Name Service (ENS) comes in.
👉 Discover how ENS simplifies crypto transactions with human-readable addresses.
What Is ENS?
The Ethereum Name Service (ENS) functions similarly to the traditional Domain Name System (DNS) used on the internet. While DNS translates domain names like cool3c.com into IP addresses, ENS maps readable names like yourname.eth to blockchain addresses — specifically Ethereum wallet and smart contract addresses.
Instead of sharing a complex hexadecimal string, users can now receive payments via simple, memorable names such as blackchainnewsroom.eth. Behind the scenes, ENS automatically resolves this name to the correct wallet address, streamlining transfers and reducing errors.
This shift is transformative. Just as the web evolved from typing IP addresses to using easy-to-remember domains, blockchain interactions are becoming more user-friendly thanks to ENS. It enhances security by minimizing copy-paste mistakes and phishing risks associated with fake addresses.
ENS operates as a decentralized system built on the Ethereum blockchain, ensuring censorship resistance and ownership control. Once you register an .eth name, it’s yours as long as you renew it — no central authority can take it away.
Understanding DApps: The Backbone of Decentralized Services
To interact with ENS, you need to understand decentralized applications (DApps) — software applications that run on blockchain networks rather than centralized servers.
Traditional apps store data in centralized databases controlled by companies. This creates vulnerabilities: data breaches, service outages, or misuse of personal information. In contrast, DApps operate on distributed networks like Ethereum, where data is transparent, immutable, and community-verified.
DApps enable functionalities such as:
- Peer-to-peer trading (e.g., Uniswap)
- NFT marketplaces (e.g., OpenSea)
- Identity and naming services (e.g., ENS)
Most DApps are built on Ethereum due to its robust infrastructure, large developer community, and strong security model. They often integrate with crypto wallets like MetaMask, allowing users to sign transactions securely without exposing private keys.
ENS itself is a DApp — one that provides foundational identity services for the decentralized web (Web3). By connecting your wallet to ENS via MetaMask, you gain full control over your digital identity.

How to Register an ENS Domain Using MetaMask
Registering an ENS name is straightforward and only takes a few minutes. Here’s a step-by-step guide:
Step 1: Access the ENS App
Visit the official ENS Manager at app.ens.domains (note: original article link removed per guidelines). This is the primary interface for managing .eth domains.
Click “Connect Wallet” in the top-right corner.
Step 2: Connect Your MetaMask Wallet
Select MetaMask from the available options. A pop-up will appear in your browser extension asking for permission to connect. Confirm the connection using your preferred Ethereum account.
Make sure you’re on the Ethereum Mainnet, not a test network.
Step 3: Search for Your Desired Name
In the search bar, type the name you’d like to register — for example, blockchainnewsroomtw.
If the name is available, you’ll see a green indicator showing “Available.” If it’s taken, you may have to try variations or wait until expiration.
Step 4: Start Registration
Click “Register”, then review the details:
- Registration period (minimum 1 year)
- Annual cost (typically around $5 USD in ETH)
- Network fee (gas fee for transaction processing)
Click “Request to Register” to proceed.
Step 5: Confirm Transaction in MetaMask
MetaMask will prompt you to confirm two transactions:
- Registration request – initiates the process.
- Finalize registration – completes ownership assignment after a short waiting period (usually 1 minute).
Approve both transactions. Once confirmed on-chain, your .eth name will appear in your wallet under “My Names.”
You can now set:
- Primary wallet address
- Reverse resolution (so others see your
.ethname when sending you funds) - Text records (for storing profile data, emails, etc.)
Why ENS Matters for Web3 Identity
Beyond convenience, ENS plays a crucial role in building decentralized identity systems. Your .eth name isn’t just a payment shortcut — it can serve as:
- A universal username across DApps
- A decentralized website URL (when paired with IPFS)
- A verifiable credential holder
For instance, linking your ENS to an IPFS-hosted site allows you to publish content without relying on traditional hosting providers. Others access it via yourname.eth, creating a truly censorship-resistant web presence.
Moreover, many DeFi platforms and NFT marketplaces now support ENS logins or payment inputs, reducing friction and enhancing user experience.
Frequently Asked Questions (FAQ)
Q: How much does an ENS domain cost?
A: Base price starts at approximately $5 per year for names longer than 7 characters. Shorter names (3–6 characters) carry premium pricing due to scarcity.
Q: Can I use ENS outside Ethereum?
A: Yes! Thanks to cross-chain standards, some wallets and services support resolving ENS names on other blockchains like Polygon or Arbitrum.
Q: Do I own my ENS name forever?
A: No — ownership requires annual renewal. If you fail to renew, the name becomes available again after expiration.
Q: Is ENS secure?
A: Yes. As a smart contract-based system on Ethereum, ENS inherits the network’s security. However, always safeguard your private keys and connected wallet.
Q: Can I sell my ENS domain?
A: Absolutely. ENS domains are ERC-721 NFTs, meaning they can be bought, sold, or traded on NFT marketplaces like OpenSea.
Q: What happens if I lose access to my wallet?
A: Since ENS is non-custodial, recovery depends on your wallet’s seed phrase. There’s no central support team — protect your recovery phrase carefully.

Final Thoughts
The Ethereum Name Service represents a major leap toward mainstream blockchain adoption. By replacing cryptic addresses with intuitive .eth names, ENS makes crypto more accessible, secure, and personal.
When combined with tools like MetaMask, users gain full autonomy over their digital identities — no intermediaries, no gatekeepers. Whether you're sending crypto, building a decentralized site, or establishing a Web3 presence, ENS offers a foundational layer of simplicity and trust.
As the ecosystem evolves, expect broader integration of ENS into social platforms, email alternatives, and even legal identity frameworks. The future of online identity isn’t just digital — it’s decentralized.
