How to Register a .bnb Domain: A Complete Beginner’s Guide

·

The world of blockchain is evolving rapidly, and with it comes the need for simpler, more user-friendly ways to interact with decentralized networks. One exciting development in this space is the launch of .bnb domains by SPACE ID, a decentralized, cross-chain name service platform built on BNB Chain. These domains offer a human-readable alternative to complex wallet addresses, making crypto transactions easier and more intuitive.

In this guide, we’ll walk you through everything you need to know about .bnb domains, how they work, and—most importantly—how to register one yourself.

What Is SPACE ID?

SPACE ID is a decentralized, open-source name service protocol designed to connect users, assets, applications, and data across multiple blockchains. It operates independently of any single chain and aims to become the universal standard for digital identity in Web3.

Backed by a seed round led by Binance, SPACE ID launched the first iteration of its service on BNB Chain: the .bnb domain. This marks a major step toward simplifying user interaction within the BNB ecosystem.

What Is a .bnb Domain?

A .bnb domain is a blockchain-based domain name that replaces your long, complicated BNB Chain wallet address (like 0x...) with a simple, memorable name (like yourname.bnb).

These domains are more than just aliases—they’re NFTs that represent ownership of your digital identity on BNB Chain. Once you own a .bnb domain, you can use it across thousands of dApps (decentralized applications) in the ecosystem for seamless interactions.

Step-by-Step Guide: How to Register a .bnb Domain

Registering a .bnb domain is straightforward—if you know the steps. Here’s a clear, beginner-friendly walkthrough.

Step 1: Connect Your Wallet

Go to the official SPACE ID app at app.space.id (note: all external links removed per guidelines). Click “Connect” in the top-right corner and connect your Web3 wallet (e.g., MetaMask, Trust Wallet).

Ensure your wallet is set to the BNB Smart Chain (BSC) network, as .bnb domains are native to this chain.

🔐 Tip: Always double-check the URL to avoid phishing sites. Only use the official domain.

Step 2: Search for Your Desired Domain

Enter the name you want (e.g., mywallet.bnb) in the search bar. If it shows “Available,” you’re in luck! If not, try variations or different names.

During the initial rollout phase, registration was limited—300 spots per day were released at 13:00 Beijing Time. While those early caps have passed, high demand may still affect availability during peak times.

Step 3: Request Registration

After confirming availability, click “Register” to proceed. You’ll be asked to choose your registration period—minimum 28 days—and see the estimated cost in BNB.

Click “Request” to initiate the first transaction. This locks your request and prevents others from claiming the same name while you complete the process. The system may take up to 30 seconds to confirm.

Step 4: Complete Payment

Once the request is confirmed (you’ll see a checkmark ✓), click “Register” again to finalize payment. This triggers the second transaction, which officially registers the domain to your wallet.

⚠️ Important: You must complete this second transaction within 7 days, or your request will expire and you’ll need to start over.

Step 5: Manage Your Domain

Congratulations! You now own a .bnb domain. Click “Manage Profile” to customize settings:

Your domain is now live and usable across BNB Chain dApps.

Why Should You Register a .bnb Domain?

You might be wondering: Why go through the trouble? Here are compelling reasons:

As more dApps integrate BNB Name Service, owning a .bnb domain becomes increasingly valuable—just like owning a premium .com in the early internet days.

Frequently Asked Questions (FAQ)

Q: How much does a .bnb domain cost?

Pricing depends on the name length and registration duration. Shorter names (3–4 characters) are typically more expensive due to higher demand. Fees are paid in BNB and include gas costs.

Q: Can I sell my .bnb domain later?

Yes! Since each .bnb domain is an NFT, you can transfer or sell it on NFT marketplaces that support BNB Chain, such as OpenSea (via BSC) or Blur.

Q: Is my .bnb domain valid on other blockchains?

Not directly—but SPACE ID supports cross-chain resolution. You can link Ethereum, Polygon, and other chain addresses to your .bnb domain, allowing unified access across ecosystems.

Q: What happens if I lose access to my wallet?

Because .bnb domains are NFTs tied to your wallet, losing access means losing control of your domain. Always back up your seed phrase securely.

Q: Can I register any name I want?

Most names are available, but offensive terms or reserved keywords (like “binance” or “space”) may be blocked. First-come, first-served applies.

Q: Do I need to renew my .bnb domain?

Yes. Domains are rented for specific periods (minimum 28 days). You must renew before expiration to retain ownership.

Final Thoughts

The launch of .bnb domains by SPACE ID represents a significant leap forward in making blockchain accessible to everyday users. By replacing complex strings of characters with simple, memorable names, we’re moving closer to mass adoption of Web3 technologies.

Whether you're a developer, investor, or simply curious about decentralized identity, registering a .bnb domain is a smart move—one that enhances usability, security, and personal branding in the digital world.

Don’t wait until your ideal name is taken. Secure your digital identity today and become part of the future of decentralized naming.
