The Ethereum Name Service (ENS) is more than just a naming protocol—it’s a foundational piece of infrastructure reshaping how users interact with the decentralized web. By replacing complex hexadecimal addresses with simple, human-readable names like yourname.eth, ENS dramatically improves usability across blockchain applications. This guide dives deep into ENS pricing, functionality, use cases, and real-world impact—delivering everything you need to understand its role in the evolving Web3 ecosystem.
What Is Ethereum Name Service (ENS)?
The Ethereum Name Service (ENS) is a decentralized, open, and extensible naming system built on the Ethereum blockchain. Its core mission is to translate easy-to-remember names such as alice.eth into machine-readable identifiers like Ethereum addresses, content hashes, and metadata.

Unlike traditional domain systems controlled by centralized authorities, ENS operates through smart contracts, ensuring censorship resistance, transparency, and user ownership. It was co-founded by Nick Johnson and Alex Van de Sande under the Ethereum Foundation and officially launched in May 2017.
How Does ENS Work?
ENS functions via two primary components: the ENS registry and resolvers.
- The ENS registry is a single smart contract that records all registered
.ethdomains. It stores each domain’s owner, resolver contract address, and time-to-live (TTL) for caching. - Resolvers are smart contracts responsible for translating an ENS name into the relevant data—such as an Ethereum address or IPFS content hash—when queried.
When someone sends cryptocurrency to bob.eth, the network uses the resolver linked to that name to fetch Bob’s actual wallet address—eliminating the risk of errors from manual input of long strings.
Key Features and Use Cases of ENS
ENS isn’t just about simplifying wallet addresses. Its architecture supports a wide range of decentralized applications and services.
1. Simplified Address Mapping
Instead of sharing 0x742d35Cc6634C0532925a3b8D4C0cF7B9B569c1f, users can send funds using jane.eth. This reduces transaction errors and boosts confidence in peer-to-peer transfers.
2. Decentralized Website Hosting
ENS integrates with IPFS (InterPlanetary File System) to map domain names to content hashes. For example, decentralizedblog.eth can point to a fully decentralized website hosted on IPFS—immune to takedowns and censorship.
3. Rich Metadata Storage
An ENS name can store metadata including:
- Multiple cryptocurrency addresses (BTC, ETH, SOL, etc.)
- Profile pictures (via NFTs or image URLs)
- Email addresses
- Social media handles
- Public keys for encryption
This turns .eth domains into portable digital identities usable across platforms.
4. Subdomain Management
Domain owners can create and manage subdomains like blog.alice.eth or shop.alice.eth, assigning them to different services or team members—ideal for DAOs, projects, or personal branding.
5. Cross-Chain Compatibility
While built on Ethereum, ENS names are increasingly supported across other networks through bridges and Layer 2 solutions. Projects like Polygon and Arbitrum recognize .eth names, enhancing cross-platform interoperability.
The Technology Behind ENS
ENS leverages Ethereum’s robust security model while maintaining flexibility through upgradable smart contract design. The system uses:
- Permanent Registrar: Manages
.ethsecond-level domains with yearly renewal fees paid in ETH. - Public Resolver: A shared resolver contract allowing users to set records without deploying their own.
- DNSSEC Integration: Enables existing DNS domains (e.g., example.com) to be imported into ENS if they support DNSSEC, linking traditional web assets to Web3.
All operations—registration, renewal, record updates—are performed on-chain, giving users full control over their digital identity.
Governance and Decentralization
In November 2021, ENS launched its ERC-20 governance token, also named ENS, distributed to early adopters, contributors, and registrants. This marked a shift toward community-led development.
The ENS DAO (Decentralized Autonomous Organization) now governs protocol upgrades, treasury management (holding millions in ETH and stablecoins), and future roadmap decisions. This ensures long-term sustainability driven by stakeholders rather than a central team.
Why ENS Matters in Web3
As blockchain usage grows, so does the need for intuitive interfaces. ENS solves one of the biggest usability barriers in crypto: complex addresses. It serves as a bridge between technical infrastructure and everyday users.
Moreover, .eth domains have become digital status symbols—short names like crypto.eth or money.eth are traded as NFTs on marketplaces like OpenSea, sometimes for tens of thousands of dollars.

Frequently Asked Questions (FAQ)
Q: How do I register an ENS domain?
A: Visit the official ENS manager app in a Web3 wallet like MetaMask. Search for your desired .eth name, choose the registration period (1+ years), and pay the fee in ETH. You’ll also need a small amount of gas for transaction confirmation.
Q: Are ENS domains NFTs?
A: Yes. Each ENS domain is represented as a non-fungable token (ERC-721) on Ethereum. This means you can transfer, sell, or trade it like any other NFT.
Q: Can I use my ENS name with wallets and exchanges?
A: Many major wallets—including MetaMask, Rainbow, and Trust Wallet—support sending funds via ENS names. Some exchanges allow linking your .eth profile for withdrawals.
Q: Do I have to renew my ENS domain?
A: Yes. Domains require annual renewal in ETH. If not renewed, they enter a grace period before becoming available for others to register.
Q: Is ENS only for Ethereum addresses?
A: No. While originally designed for Ethereum, ENS supports over 500+ blockchain addresses (Bitcoin, Litecoin, Solana, etc.) and even non-blockchain identifiers like Avatars and emails.
Q: How is ENS different from traditional domains like .com?
A: Traditional domains rely on centralized registrars (e.g., GoDaddy). ENS is decentralized—no single entity controls it. Additionally, .eth domains give users full ownership and programmability within dApps.
