Best Domain Names for Crypto & Web3 Projects

Traditional DNS, ENS, Unstoppable Domains—which should you use? Here's how to pick domains that build trust in Web3.

⚠️ The Trust Problem

Crypto is plagued by scams. Your domain is a major trust signal. Cheap TLDs, weird extensions, and typosquatting-style domains are immediate red flags to savvy users.

Traditional Domains for Crypto Projects

Extension Trust Level Cost Notes
.com ⭐⭐⭐⭐⭐ $10-15 Best for legitimacy
.io ⭐⭐⭐⭐ $45-60 Tech/crypto standard
.co ⭐⭐⭐⭐ $25-35 Good alternative
.xyz ⭐⭐⭐ $1-12 Mixed—cheap but used by some legit projects
.finance ⭐⭐⭐ $50-80 DeFi-specific
.network ⭐⭐⭐ $15-25 For protocols

Blockchain Domains (ENS, Unstoppable)

These live on-chain rather than in traditional DNS:

ENS (.eth)

  • Registry: Ethereum Name Service
  • Cost: ~$5/year + gas fees
  • Use: Wallet addresses, decentralized identity
  • Browser support: Brave, Opera, MetaMask

Best for: Personal Web3 identity, wallet receiving

Unstoppable Domains

  • Extensions: .crypto, .nft, .wallet, .blockchain
  • Cost: $20-40 one-time (no renewal)
  • Use: Website + wallet address
  • Browser support: Brave, Opera, extensions

Best for: Long-term ownership, no renewals

Traditional vs Blockchain: Which to Use?

Our Recommendation

Get both. Here's why:

  • ✓ Traditional (.com/.io): Main website, SEO, general users
  • ✓ Blockchain (.eth): Web3 identity, wallet address, crypto-native users

Your .com is for discovery and legitimacy. Your .eth is for on-chain identity and crypto-native functionality.

Crypto Domain Red Flags

🚩 Typosquatting: Domains like uniswapp.com or metamask-wallet.io scream phishing.

🚩 Too-cheap TLDs: .tk, .ml, .ga are free and heavily abused by scammers.

🚩 Keyword spam: "guaranteed-10x-crypto-returns.xyz" isn't fooling anyone smart.

🚩 Missing HTTPS: In 2025, there's no excuse for an unsecured crypto site.

Domain Strategy for Crypto Projects

  2. Register common misspellings to prevent phishing
  3. Get projectname.eth for Web3 identity
  4. Consider .crypto from Unstoppable for one-time fee
  5. Use HTTPS everywhere—Let's Encrypt is free
  6. Add your official domain to Twitter bio, Discord, etc.
