What are ETH Domains?

Ethereum name service (ENS) also known as ETH domains are domain names that are blockchain-based and have the extension.eth. A .eth domain is the most common type of Web3 domain, and the terms "ETH domain," ".eth domain," and "ENS domain" all refer to the same thing: a name registered through the Ethereum Name Service. Essentially, these domains are registered on the Ethereum blockchain and enable you to convert your long and often confusing crypto wallet addresses into easy-to-remember names such as john.eth or wallet.eth.

With an ETH domain, users can simply enter their custom .eth username to conduct transactions, host websites, and use decentralized applications, eliminating the need to retype or screenshot lengthy wallet addresses.

How ETH Domains Work?

In two words: Smart contracts.

Here’s how it works:

When you buy an ETH domain it is minted as an NFT (Non-Fungible Token) using the ERC-721 standard.
The domain is linked to your wallet (mirrored on chain), enabling crypto transactions, dApp logins, and decentralized identities.
ENS domains can be extended for additional use cases, such as linking IPFS websites, verifying ownership, and sending or receiving assets.

How to Buy a .eth Domain

Registering a .eth domain takes only a few minutes. Here's the step-by-step process:

1. Set up an Ethereum wallet. You'll need a Web3 wallet such as MetaMask, Coinbase Wallet, or Rainbow. This wallet will hold your domain and cover the registration cost in ETH.

2. Search for your domain. Head to a registrar and check whether your desired name (for example, yourname.eth) is available. If it's taken, you'll need to choose another name or buy it on a secondary marketplace.

3. Choose your registration period and confirm. .eth domains are registered for a set time (typically one year or more) and require renewal. Review the cost — including network gas fees — before confirming.

4. Complete the transaction. Approve the payment in your wallet. Once the transaction is confirmed on-chain, the domain is minted as an NFT and linked to your address.

5. Set your records. After registration, point your domain to your wallet address, an IPFS website, or your social profiles through the resolver settings.

One thing to keep in mind: because .eth domains carry renewal fees and are locked to the Ethereum blockchain, it's worth considering whether a one-time, multi-chain alternative fits your needs better — more on that below.

What Can You Do With a .eth Domain?

A .eth domain is more than a shortened wallet address. Here are its main real-world use cases:

Simplify crypto transactions. Replace long, error-prone wallet addresses with a readable name like yourname.eth to send and receive ETH and ERC-20 tokens.

Use it as your wallet address. Your .eth name is your Ethereum address. Instead of sharing a 42-character string, you share yourname.eth, easier to remember and harder to get wrong.

Host a decentralized website. Link your domain to IPFS or other decentralized storage to publish censorship-resistant sites that resolve directly from your .eth name.

Use it as a username on social and dApps. A .eth domain works as a portable Web3 identity. Many platforms, including X, let you display your .eth name, and it doubles as login authentication across major decentralized applications.

Build a digital identity. Manage NFTs, verify ownership, and present a single recognizable name across the Ethereum ecosystem.

Limitations of ETH Domains

ETH domains are powerful, but they come with trade-offs worth knowing before you buy:

- Ethereum only. A .eth domain works within the Ethereum ecosystem. If you operate across other chains (Solana, BNB Chain, and so on), it won't natively follow you there.
- Recurring renewal fees. You don't own a .eth domain outright — you lease it, and fees can rise over time.
- No custom TLD. Every ENS name must end in .eth. You can't create your own extension like .crypto or .yourbrand.

If these limitations matter to you, there's an alternative worth considering.

How Much Does a .eth Domain Cost?

The price of a .eth domain depends mainly on two factors: length and demand. Shorter names are scarcer, so they cost more. As a rough guide, annual registration fees break down like this:

- 3-character names: around $640 per year
- 4-character names: around $160 per year
- 5+ character names: around $5 per year

On top of the registration fee, you'll always pay network gas fees, which vary with Ethereum network congestion at the time of purchase. Remember that these are recurring fees, .eth domains must be renewed to retain ownership, unlike some alternatives that charge a single one-time payment.

A Flexible Alternative: Custom TLDs with Freename

If you want lifetime ownership, multi-chain support, and the freedom to create your own extension, Freename offers a different approach to Web3 domains.

Here’s a quick breakdown of the side-by-side comparison of ENS domains and Freename domains, here you go:

Feature	ENS Domains	Freename Domains
Customizable TLD Options	No (Only “.eth”)	Yes (You can create unique TLDs)
Renewal Fees	Yes	No (One-time payment)
Blockchain Support	Ethereum only	Multi-chain (Polygon, BSC, Cronos, Aurora)
Passive Income	No	Yes (50% royalty earnings from TLD sales)
Ownership Model	NFT-based	NFT-based with enhanced customization

Examples of Freename TLDs

.realestate – Ideal for businesses or projects in the real estate sector. Register domains like listings.realestate or viewings.realestate to showcase real estate listings and property services.

Passive Income

One additional benefit of using a Freename domain is that you can earn passive income by creating and owning your own Top-Level Domains (TLDs), such as .stake or .metaverse. Once registered, TLDs are owned for life with no renewal fees. Users can enable a royalty program, earning 50% of registration fees every time someone buys a Second-Level Domain (SLD) under their TLD. With customizable reseller pages and multi-blockchain support, meaning users can monetize their domains indefinitely, turning them into profitable, decentralized assets in the rapidly evolving Web3 ecosystem.

Conclusion

The TLDR of ETH domains is that they simplify your ETH wallet addresses down to a simple and easy-to-remember domain name that enhances integration with decentralized apps on Ethereum. Their main use cases besides a shorter ETH address, include hosting websites, and establishing your digital identity. However, ETH domains come with some drawbacks like renewal fees, limited customization, and usability confined to Ethereum. If that’s a problem for you, an alternative is Freename, as they provide customizable TLDs, lifetime ownership with no renewal fees, and income potential through royalties. The Web3 domain space offers a wealth of possibilities, whether you want a basic ETH domain or to create and monetize your own TLD, the choice is ultimately yours.
