ENS Domains: How Ethereum Name Service Simplifies Crypto for Users

Ethereum Name Service turns crypto addresses into readable names called ENS domains. Instead of sending funds to 0x8f3a92b1c7d4e5f6... you send them to company.eth.

Without that layer, mistakes get expensive. In December 2025, a crypto trader copied a spoofed address from their transaction history and lost $50 million. The fake matched the first five and last four characters of the real one. The blockchain accepted it. Gone in minutes.

ENS prevents this. Each .eth domain lives on Ethereum as a token. Whoever holds it controls where it points. Register treasury.company.eth, connect it to your company wallet, and every payment to that name lands in your account. No hex strings. No copy-paste errors.

For finance teams, readable names cut down on failed transfers and speed up reconciliation:

• Treasury wallets become treasury.company.eth

• Payroll accounts become payroll.company.eth

• Auditors verify transfers against readable names

• Partners and vendors see a name they recognize

ENS doubles as brand identity. A .eth name is your .com for Web3. Major wallets and exchanges display it next to every transfer. Your clients see company.eth, not 0x8f3a... They know it is y

Go to app.ens.domains, connect your wallet, and search for the name you want. If company.eth is available, the interface shows the cost in ETH.

Five-character names cost around $5 per year. Four characters cost around $160. Three characters cost around $640. You can register for multiple years at once if you want to avoid renewing every year.

ENSv2 launched in 2025 and reduced registration gas costs by 99%. Before, registering a name could cost $20 or more in gas during busy network periods. Now, even during peak activity, gas stays under a dollar.

The upgrade also added cross-chain resolution. Your .eth name works across 60+ networks without separate configuration for each chain.

ENSv2 kept everything on Ethereum mainnet rather than moving to a separate chain. Your existing .eth names still work exactly as before. Nothing to migrate.

Registration takes two transactions. The first one reserves the name so nobody can snatch it while you complete the process:

• Click Request to register and approve the first transaction. This commits your intent but does not pay for the name yet.

• Wait about 60 seconds. Do not clear your browser cache or switch devices.

• Click Register and approve the second transaction. This pays the fee and completes registration.

The .eth name appears in your wallet as an NFT. You control it until it expires.

Go to Manage Name to:

• Set the public resolver and add your ETH address

• Mark it as your Primary ENS Name so others see your .eth name when they interact with you

• Create subdomains for treasury, payroll, or other teams

If your company accepts or sends crypto, you probably manage multiple wallets. Treasury, payroll, vendor payments. Each has a 42-character address. Each is easy to confuse.

Direct trades with partners and vendor payments go to company.eth. Your accounting team sees that identifier on settlement records. Your legal team sees it on contracts. You always know where money came from and where it went.

Your clients and regulators see that same identifier repeatedly. Owning company.eth works like holding a premium .com domain. It links your Web3 wallets to your existing brand.

Once you own company.eth, you control every subdomain under it. The same structure works for DAOs: treasury.dao.eth for reserves, members.dao.eth for governance roles. When audit time comes, you trace transactions against labels, not hex strings.

When a vendor sends to company.eth, they can verify ownership before the transfer. They look up the ENS record on Etherscan, a public blockchain explorer, and confirm it resolves to your wallet.

This changes how you handle settlements. Include your .eth identifier in API docs and onboarding flows. Once verified, that identifier works for every future transfer. No more double-checking hex strings on every transaction.

Your .eth name only matters if the tools your partners use can read it. Most major wallets and exchanges already support ENS resolution.

• Wallets: MetaMask, Trust Wallet, Ledger, and Trezor resolve .eth names by default. When you send to company.eth, the wallet looks up the address automatically. No manual copying required.

• Exchanges: Gate, MEXC, and Bybit support ENS for withdrawals. You can send directly to a .eth name instead of pasting a hex address. This reduces errors when moving funds between exchange accounts and treasury wallets.

• dApps and protocols: DeFi protocols and Web3 social platforms like Farcaster and Lens use ENS as the default identity layer. If your company operates in DeFi or Web3 social, your .eth name follows you across platforms.

When you share company.eth with a partner, they can verify and send from any of these tools without asking for your hex address. The more integrations ENS has, the fewer places where raw addresses create friction.

ENS domain names are readable, which makes them easy to spoof. Before you transfer to any .eth name, verify it.

Etherscan is a public tool that lets you inspect any Ethereum address or ENS domain. Search for the name, open the ENS details, and look at the owner. That owner should match what your partner shows on their website, docs, or official communications. For larger partners, expect a shared account with multiple signers, not a personal one.

Owning a name is one thing. Pointing it to the right destination is another. Open the ENS page and check the Primary Address or ETH Record. Funds go wherever that record points. Compare it against what your partner publishes on their website and payment documentation. 

If it changes often or does not match, stop and confirm directly before transferring.

Typosquatting means registering a name that looks almost identical to a real one: vitalic.eth instead of vitalik.eth, or paymant.company.eth instead of payment.company.eth. The difference is one character, and your money goes to the wrong place.

Type the full name manually every time. Do not copy from emails, chats, or social media. Train your finance team to compare character by character. Pay attention to letters that look alike: lowercase L and the number 1, the letter O and zero.

For treasury-level payments, send a small test amount first. Ask the recipient to confirm receipt through a separate channel: email, phone, or a known support line. If anything looks off, pause and check with your security team before continuing.

ENS dominates Ethereum, but it is not the only naming service in crypto. Depending on your use case, other options might fit better.

Unstoppable Domains offers extensions like .crypto, .wallet, and .x with one key difference: no renewal fees. You pay once and own the domain permanently. The tradeoff is fewer integrations than ENS. Not all wallets and exchanges resolve Unstoppable domains by default.

Layer-2 networks have their own naming systems. Basenames on Base and Linea Names on Linea offer cheaper registration because gas fees are lower on L2s. If your operations run primarily on one L2, a native naming service might make more sense than bridging an ENS domain.

ENS also supports linking traditional DNS domains. If you already own company.com, you can connect it to your Ethereum address without registering a separate .eth name. This works for businesses that want Web3 functionality without managing another domain.

For card-linked payouts and B2B settlements, Mercuryo's Mastercard Crypto Credential offers verified usernames tied to self-custody wallets, bringing readable identity to payment flows where partners expect KYC verification built in.

Naming services are still early. ENS and other naming services have millions of registered names combined, but most crypto transactions still use raw addresses. The infrastructure exists, but the habit does not exist.

That gap is closing. Wallets like MetaMask, Trust Wallet, and Ledger display .eth names by default. Major exchanges support ENS for withdrawals. The friction that kept naming services niche is disappearing.

Payments are following the same path. Verified usernames, KYC-linked aliases, and on-chain identity standards are converging. The question is no longer whether readable names will replace hex strings, but how fast.
