What Is an ENS Domain?

An ENS domain is a service that replaces Ethereum addresses with memorable names, such as turning a long 0x address into alice.eth. This reduces errors from manual copying and makes on-chain identities more visible and intuitive.

An Ethereum address is similar to a bank account number—precise but hard to remember. ENS domains function more like contact nicknames or website URLs, making payments, discovery, and sharing easier. You can point an ENS domain to your receiving address and attach public profile information like avatars or bios.

Why Are ENS Domains Important?

ENS domains are significant because they solve the challenge of hard-to-remember and error-prone addresses, bringing identity to blockchain applications and social scenarios. Many wallets and Dapps display your ENS name, making interactions more trustworthy.

For transfers, friends only need to enter alice.eth to find your address, reducing the risk of asset loss due to copying mistakes. In communities and social platforms, the combination of an ENS name and avatar becomes a verifiable on-chain calling card.

How Do ENS Domains Work?

ENS domains operate through smart contracts, which are self-executing code responsible for name registration, renewal, and ownership records. Each name is linked to a “resolver,” which acts like an address book to store which address corresponds to each name.

The resolution process involves two steps: first, locating the ownership and resolver for the name; second, reading the specific records from the resolver, such as ETH receiving addresses, text records, or website content hashes. Many implementations support “reverse resolution,” allowing an address to display as its ENS name for easy identification.

How Do You Register an ENS Domain?

Registering an ENS domain is straightforward but requires following steps and preparing gas fees (transaction fees on-chain).

Step 1: Prepare a wallet and a small amount of ETH. The wallet acts as your online bank card for initiating transactions and signing; ETH covers registration fees and gas.

Step 2: Go to the official app site (typically app.ens.domains), enter your desired name in the search box, and check its availability.

Step 3: Select the registration period. ENS uses an annual subscription model; prices vary by name length—3–4 character names are usually more expensive, while names with 5 or more characters cost less.

Step 4: Initiate the “registration request” and wait for the safety buffer prompted by the system. Then confirm a second transaction to finalize registration, which helps prevent front-running.

Step 5: Set up resolvers and records. Point your ENS domain to your receiving address, add avatars, social links, or website content hashes if needed, and enable “reverse resolution” so your address shows as your chosen name.

Step 6: Backup and reminders. Record your expiration date and set renewal reminders to avoid losing your domain to someone else.

How Do You Use ENS Domains in Wallets and Gate?

ENS domains can be directly displayed as your name in wallets; when transferring assets, you can input the recipient’s ENS domain, which the system resolves to a 0x address before sending.

In Gate’s asset management and withdrawal scenarios, always verify that the resolved address matches the intended destination. The recommended approach is: first, check alice.eth’s current resolved 0x address on the ENS official site or supported blockchain explorer; then paste this address into Gate’s withdrawal field to ensure you’re operating on Ethereum mainnet and that the address matches exactly.

If an interface allows direct input of an ENS domain, always review the displayed resolved address to ensure it matches your expectations. Before and after transfers, keep screenshots and TxIDs (transaction numbers) for tracking purposes.

What Can You Do With an ENS Domain?

ENS domains serve not only as payment identifiers but also allow management of subdomains. For example, you can create team.alice.eth for colleagues or bot wallets—similar to managing company email domains.

ENS domains support “text records,” such as avatars, bios, or social account links. They also support “multi-chain addresses,” allowing you to save payment addresses from different networks under one domain so friends can retrieve the correct one easily.

If you run a decentralized website, you can point your ENS domain to its content hash (commonly on IPFS). IPFS is a distributed file storage system; paired with gateways, browsers can access these sites. Using an ENS domain as an entry point makes them easier to remember.

How Are ENS Domains Different from DNS Domains and Other Naming Services?

ENS domains are designed for on-chain identities and addresses, with records stored in smart contracts. DNS domains serve websites and servers, managed by registrars and hierarchical DNS authorities—their users and tech stacks are fundamentally different.

Compared with one-time purchase blockchain naming services, ENS domains require annual renewal and have expiry mechanisms; shorter names cost more. ENS offers high ecosystem compatibility, with many wallets, Dapps, and tools supporting resolution and display.

What Are the Risks and Costs of Using ENS Domains?

Costs include registration fees, renewal fees, and gas for setting or updating records. Registration prices are generally USD-based but paid in ETH on-chain, with oracles providing exchange rates. Oracles are services that securely bring off-chain data like prices onto the blockchain.

Common risks include:

• Lookalike character confusion and phishing. For example, mixing up “l” with “I” could send assets to the wrong address. Always compare the resolved 0x address with your confirmed destination before transferring.
• Expiry and sniping. Failing to renew means losing your name; set reminders and renew early.
• Incorrect resolver or record settings. Mistakes can direct payments to old addresses; notify contacts after changes and update displays on commonly used platforms.
• Over-reliance on offline resolution or unofficial sources. Use official apps or trusted explorers to verify resolution results.

When funds are involved, it’s better to double-check than rely on word-of-mouth names; always confirm that the 0x address and network match exactly.

What Are the Trends in ENS Domains?

As of H1 2025, public dashboards (such as Dune Analytics) show continued growth in both ENS domain resolutions and holders. More wallets and social tools use ENS as a default identity display.

Technically, more resolvers adopt “off-chain read/CCIP Read” mechanisms for securely reading some data outside contracts to improve scalability; L2 and cross-chain support is also increasing, promising lower costs for record updates and broader application coverage.

Regardless of market cycles, demand for short or brand-related names remains strong. Organizations and creators use subdomains to manage member identities, improving collaboration and recognition.

Quick Recap of ENS Domain Essentials

ENS domains turn hard-to-remember addresses into easy-to-use names for safer transfers and clearer identity visibility; managed by smart contracts and resolvers, they support multi-chain addresses, text records, and subdomains. Registration requires annual fees plus gas—always pay attention to expiration dates and correct resolution. For withdrawals and receipts on Gate, verify the resolved 0x address before proceeding. Ecosystem support continues expanding; unified identity and content entry points are becoming mainstream.

FAQ

What’s the Difference Between ENS Domains and Traditional Domains?

ENS is a blockchain-based domain system managed by smart contracts; traditional domains are controlled by centralized organizations. With ENS domains you truly own your name—you can transfer or sell it freely without institutional control; traditional domains are only leased each year under registrar restrictions. Simply put: ENS domains are digital assets you own; traditional domains are just rented services.

What Can You Do With an ENS Domain?

ENS domains are mainly used for receiving crypto asset transfers and displaying identity. Once set up, others can transfer directly to your ENS domain (e.g., vitalik.eth) instead of copying lengthy wallet addresses. They can also be displayed on social media or wallets to build personal brands. Some apps even allow login via ENS.

Do ENS Domains Require Annual Renewal?

Yes—ENS domains must be renewed periodically. The longer you register upfront, the lower your yearly cost (typically a few to several dozen dollars). Pricing depends on name length (shorter names cost more) and registration period. Renewals can be done via Gate or the official site; if you miss renewal deadlines your domain will be released for others to register.

Who Should Register an ENS Domain?

Frequent crypto asset receivers (such as traders, creators, project teams) benefit most from registering. A concise ENS domain increases transfer security by reducing input errors. It’s also valuable for personal branding or participation in DeFi ecosystems. Regular holders without special needs may not require registration.

How Do You Use an ENS Domain in Gate Wallet?

After linking your wallet with your ENS domain in Gate Wallet settings, others can send assets directly using your domain name. To do this: go to wallet settings, bind your registered ENS domain, then confirm association. Your domain will appear in wallet profiles—others can send assets directly via your name, which is automatically resolved by the system to your wallet address.
