Best Domain Extensions for Web3 Projects

From DAOs to NFT marketplaces, the right domain can give your Web3 project instant credibility. Below are 13 TLDs that have become favorites in the blockchain and decentralized ecosystem.

1. .xyz – The Web3 wildcard

From mirror.xyz to ENS subdomains, .xyz has become the go-to for decentralized creators. It’s short, futuristic, and ideal for DAOs, indie protocols, and Web3 portfolios.

2. .io – The tech crowd favorite

Originally the ccTLD of a small territory, .io has become a badge of credibility among developers. It works perfectly for blockchain explorers, DEXs, and staking platforms.

3. .app – Built-in HTTPS, perfect for dApps

If your crypto tool runs in the browser or on mobile, .app enforces HTTPS and says “I built something useful.” Great for wallets, trackers, and NFT marketplaces.

4. .dev – For the builders behind the blockchain

Use .dev for documentation, SDKs, or versioned releases. It’s clean, focused, and secure — ideal for developers.

5. .tech – A no-brainer for Web3 innovators

Perfect for token platforms, metaverse experiments, and anything blockchain-related. If it’s tech, .tech fits like a glove.

6. .network – Especially if you're building one

Web3 thrives on networks. Use .network for Layer 1s, staking dashboards, or ecosystem hubs.

7. .cloud – Not just for Web2 anymore

If you’re using decentralized storage like IPFS, Filecoin, or Arweave, .cloud is a natural choice for infrastructure projects.

8. .link – For when you just need a way in

Quick and shareable, .link works for token claim portals, wallet dashboards, or even your crypto bio link.

9. .space – For your crypto collective or metaverse idea

Community-driven projects, virtual galleries, and metaverse hubs shine on .space.

10. .online – No assumptions, just presence

Generic but versatile, .online is great for DAOs, NFT collectives, or side projects when your first choice isn’t available.

11. .team – For your protocol crew or DAO core

Web3 is collaborative. .team showcases contributors, proposals, and governance groups.

12. .live – Because the timeline never sleeps

Great for AMAs, protocol launches, or live dashboards. Keep your community updated in real time.

13. .finance & .capital – Serious DeFi vibes

These TLDs are perfect for investment DAOs, analytics dashboards, and DeFi funds. Use .finance or .capital depending on your project’s tone.
