Pourquoi devriez-vous vous soucier des domaines Web3 pour votre adresse crypto

If you’ve ever tried to send crypto and double-checked a 40-character wallet address five times before hitting “send,” you already know the problem. Crypto addresses are lengthy, difficult to understand, and prone to typos. This has prevented cryptocurrency from being as user-friendly as it ought to be for years.

Are you sick of the lengthy, weird character strings that show in your cryptocurrency wallet? Good news! You can finally get rid of the randomness and use something easy to remember, thanks to the collaboration between Freename and Bitcoin.com. Now, you can pick a name that accurately captures who you are!

This is a significant step in ensuring that cryptocurrency is available to anyone. Cryptocurrency can now be sent and received much like an email. A straightforward, human-friendly name for your wallet is entered, saving you the trouble of copying and verifying complex addresses. Simplicity is the key in knowing how to choose a Web3 domain. Consider what is unique to you, memorable, and meaningful.

What does the announcement tell us?

Here are some of the key take‑aways from the press release:

Freename partnered with Bitcoin.com Wallet to bring native Web3 domain resolution to more than 75 million wallet users.

They launched a new TLD: “.sat”, inspired by the smallest unit of Bitcoin (a satoshi). Owning a “yourname.sat” means your Bitcoin identity is your chosen handle.

The integration is designed to work natively within the wallet on mobile—no browser extension, no plug‑in required.

Freename also supports more traditional Web2 domains (like .com, .ai, .xyz) being used “on‑chain” for crypto payments and wallet resolution.

From this, we can draw guidance on how to choose a Web3 domain and what makes a TLD (top‑level domain) “best” for a crypto address.

What makes a “best” TLD for a crypto address?

When thinking about the top‑level domain part of your Web3 domain (for example, the “.sat” in yourname.sat), you should evaluate based on several criteria. Below are the major ones:

Relevance to crypto / blockchain identityA TLD that signals “this is my crypto handle” is helpful. For example, .sat has a strong link to Bitcoin (sat‑oshi). That relevance helps when someone sees your domain and recognises it means “send crypto here”. So when you ask how to choose a Web3 domain, pick a TLD that aligns with your use case: Bitcoin‑centric, or multi‑chain, or brand/identity.

Ease of recognition and memorabilityThe simpler and shorter the TLD, the more people will remember it. Using something like .sat is catchy. If you pick a long or obscure TLD (like .blockchainwallet123), you lose part of the benefit. So in selecting how to choose a Web3 domain, you should prioritise memorability.

Wallet / ecosystem integrationIt’s not enough to own the domain: the wallet or platform you use must recognise and resolve it. In the Freename + Bitcoin.com case, the integration is native: you type “alice.sat” in the send field, and the wallet resolves it. If you pick a TLD that isn’t widely supported, you might lose that convenience. So when considering how to choose a Web3 domain, check ecosystem support.

Security and long‑term stabilityA TLD backed by a credible registrar or a large ecosystem is more likely to remain functional, supported and secure. For example, Freename is ICANN‑accredited and has launched these new TLDs. When you think how to choose a Web3 domain, include trustworthiness.

Flexibility of use beyond crypto paymentsSome Web3 domains and TLDs enable more than just wallet addresses—they can work for websites, email identities, payments, multiple chains. The press release mentions that domains can connect to websites, payments, email. If you anticipate doing more than sending/receiving crypto (e.g., building a web identity, receiving donations), consider a TLD with that capability.

Cost and renewal considerationsSome TLDs are premium or expensive to register or renew. When you ask how to choose a Web3 domain, you should factor in ongoing cost. The announcement suggests promotions and discounts but future cost may vary.

Availability and uniquenessJust like web domains, you want something unique but also available. If the TLD is popular, many names will already be taken. So when figuring how to choose a Web3 domain, evaluate both the TLD and your desired name within it.

Top candidate TLDs for crypto addresses

Based on the above criteria and the current market/announcement, here are some of the best TLDs to consider for a crypto address:

.sat – This is the TLD from Freename/Bitcoin.com, clearly oriented to Bitcoin use. Because it is new, you may have more chances to pick a short name. Good integration, relevant branding, native wallet support. This makes .sat a strong contender when thinking how to choose a Web3 domain.

.crypto, .wallet, .eth, .btc – These are more generic Web3‑oriented TLDs (or domain namespaces) that have been around. If your use is multi‑chain or you want recognition outside of Bitcoin alone, a broader one may help.

.com / .ai / .xyz – Traditional Web2 TLDs but here repurposed for Web3 use (via Freename’s “blockchain‑mirroring” tech). If you already have a brand with “.com”, then turning that into your wallet domain may help brand consistency. The trade‑off: maybe less “crypto‑specific” signalling. So when thinking how to choose a Web3 domain, if branding matters, a traditional TLD may win.

Brand‑specific or niche TLDs – Some platforms allow creation of custom TLDs or less common ones. If you have a niche community or brand, you might pick a specialized TLD. But the risk: lesser recognition and potentially weaker ecosystem support.

Step‑by‑step: How to choose a Web3 domain

Putting it all together, here’s a practical guide:

Define your use caseAre you using this as a personal wallet address (for Bitcoin, Ethereum, multi‑chain)? Are you using it for your brand? Are you building a website + wallet + identity? Clarifying the use case helps narrow which TLD fits best.

Shortlist your desired handleThink of a simple name: your name, your brand, your nickname. Make it readable, easy to type, easy to say. Then pair it with candidate TLDs (e.g., yourname.sat, yourname.crypto, yourbrand.com). This step is central in how to choose a Web3 domain.

Evaluate TLD options via the criteria above

Does the TLD signal crypto/identity clearly?

Is it widely supported in wallets, platforms, browsers (native resolution)?

Is it secure, backed by credible registrar?

Does it allow you future flexibility (website, email, url) beyond wallet addresses?

What is the cost and renewal schedule?

Is your chosen name still available under the TLD?These are essential when deciding how to choose a Web3 domain.

Check ecosystem integrationFor example: the “.sat” TLD is integrated with Bitcoin.com Wallet. See how your wallet or platform recognises the domain. Confirm that you can type “yourname.sat” (or whatever) and send funds without additional plug‑ins. This ensures your domain will function as intended.

Branding & recognitionEven though the domain is meant for wallet addresses, it will likely be shared, printed, put on business cards, etc. Choose a TLD that aligns with your identity. If you’re in the crypto space, a crypto‑specific TLD signals “this is my wallet”. If you’re a more general brand, a .com may feel more familiar. In how to choose a Web3 domain, branding is often under‑considered.

Lock in your registration and configure your domainOnce you pick, register it through a trusted registrar (like Freename). Map the domain to your wallet address, set up resolution. Configure any additional features (website, email, alias). Then test: send a small amount to the domain, confirm it resolves to your wallet. This is the operational side of how to choose a Web3 domain: make sure it actually works.

Maintain and secure your domainTreat this domain as you would a wallet: apply security best practices (strong registrar account security, two‑factor authentication, monitor renewals). Because your domain is your identity, losing it or having it compromised can cause harm. So when you select how to choose a Web3 domain, security and maintenance are essential.

Final thoughts

There is no one “perfect” TLD that fits everyone. The best TLD depends on your specific goals, audience, and ecosystem. But based on the emerging trend and current infrastructure, .sat stands out as a strong candidate for Bitcoin‑focused users because of its native integration, relevance, and backing by major players (Freename + Bitcoin.com). If you’re operating more broadly or building a brand beyond crypto, a more traditional TLD repurposed for Web3 use might be right for you.

When you ask how to choose a Web3 domain, remember that the domain is more than just a wallet alias—it becomes part of your identity, your brand, your digital presence. Pick a TLD that fits your identity, ensures usability for your audience, and is supported by ecosystem infrastructure. Use the criteria above—relevance, recognition, integration, security, flexibility, cost—to guide you.

As crypto and Web3 adoption continues, human‑readable domains will become ever more mainstream. The days of copy‑pasting 40‑character wallet strings are numbered. By choosing your Web3 domain wisely now, you position yourself for smoother interactions, better identity control, and a more professional presence.

For those in the crypto space and beyond: take a moment, go through the steps above, and pick the domain that best aligns with your future. And if you’re ready, consider registering the TLD, configuring it, and testing it so you’re ahead of the curve rather than scrambling later.
