The internet evolves through naming layers. In the 90s, .com became the digital storefront. In the 2000s, .org and .net carried authority and networks. Today, blockchain naming systems are rewriting that playbook. TLDs (top-level domains) are no longer just about websites – they now anchor digital identity, payments, and onchain interactions.
As 2025 unfolds, blockchain naming is moving from experiment to mainstream. Major brands are adopting wallet-readable names, investors are competing for scarce words, and communities are rallying around shared identities. Some of these TLDs extend legacies into Web3, while others are entirely native to the onchain world. This blog highlights the most important TLDs you can’t miss—names that are shaping culture, commerce, and identity for the decade ahead.
Looking for the Top 10 Crypto Domain Name Providers for All Blockchains? Click here to learn more.
1. .eth : Ethereum’s Identity Layer
- Origin: Launched by the Ethereum Name Service (ENS) in 2017.
- Why it matters: .eth names map directly to Ethereum wallet addresses, making crypto transactions as simple as typing a name.
- Market proof: Budweiser purchased beer.eth in 2021, signaling how mainstream brands view ENS names as cultural and commercial assets. For individuals, vitalik.eth – owned by Ethereum co-founder Vitalik Buterin, remains the ultimate status symbol of personal identity onchain.
- Takeaway: .eth is already a cultural and financial status symbol in Web3.
2. .dao : The Governance Standard
- Why it matters: DAOs (Decentralized Autonomous Organizations) represent the new model of digital collaboration. .dao domains offer communities a natural naming anchor.
- Use cases: A DAO using treasury.dao or governance.dao signals legitimacy and trust.
- Future potential: As DAOs mature into billion-dollar entities, .dao could become their de facto namespace.
3. .nft : The Collectibles Hub
- Why it matters: NFTs are not just art; they represent digital ownership in gaming, fashion, IP, and entertainment.
- Market proof: Market proof: Opensea.eth, tied to the largest NFT marketplace, became a widely recognized address. Names like artblocks.nft illustrate how creators and collectors are extending identity into the NFT world itself.
- Future potential: .nft provides identity layers for creators, collectors, and platforms.

4. .polygon : Scaling Identity
- Why it matters: Polygon has become the scaling solution of choice for Web3, powering projects across DeFi, gaming, and consumer apps.
- Strength: While not a formal TLD in the DNS sense, Polygon-native naming is emerging through ecosystem tools and integrations, giving projects low-cost, high-speed identity within one of the busiest chains. While not a traditional ICANN-approved TLD, Polygon-linked naming has gained traction within its ecosystem.
- Future potential: As L2 adoption grows, ecosystem-linked namespaces could become default anchors for dApps and wallets operating in this space.
5. .web3 : The Defining TLD for a Movement
- Why it matters: Unlike ecosystem-specific names, .web3 is universal. It doesn’t belong to Ethereum, Polygon, or Solana, it belongs to the idea of Web3 itself. That universality makes it relevant to every chain, every protocol, and every user.
- Future potential: .web3 is poised to be the flagship identity layer for the next billion users, standing as the cultural banner of the decentralized era.
Why These TLDs Stand Out
Across these examples, three traits stand out:
- First-mover advantage: Early adopters consistently capture the best names at the lowest cost.
- Cross-chain relevance: TLDs that work across ecosystems hold broader appeal and higher resale value.
- Brand magnetism: Simple, category-defining words attract not only communities but also global companies looking to signal leadership.
Conclusion
Choosing the right TLD today is less about vanity and more about positioning. The strongest names – whether .eth, .dao, .nft, .polygon, or .web3 – carry signals of authority, alignment, and community.
Trends may shift, but categories endure. The names that define identity, governance, ownership, scalability, and universality will be remembered as the foundation of the decentralized internet.For investors, projects, and communities, these names aren’t optional extras – they’re strategic assets that will define who leads in the decentralized era.
