What Is SPACE ID?
SPACE ID is building a universal naming service network designed to seamlessly connect people, information, assets, and applications across multiple blockchains. As a decentralized, censorship-resistant, and open-source platform, SPACE ID enables users to replace complex wallet addresses with simple, human-readable names.
By abstracting the technical complexity of blockchain interactions, SPACE ID enhances usability across decentralized applications (dApps), wallets, and exchanges. It supports cross-chain compatibility, making it a foundational layer for the future of Web3 identity.
What Is a .bnb Domain?
The .bnb domain is the first implementation of the SPACE ID naming system on the BNB Chain. It allows users to replace their long, alphanumeric BNB Chain wallet addresses (e.g., 0x...) with a short, memorable name like yourname.bnb.
Each .bnb domain functions as an NFT (Non-Fungible Token) that represents ownership of the domain. Once registered, you can configure custom records to link your domain to your wallet, website, social profiles, or even email — enabling smoother interactions across thousands of dApps in the BNB ecosystem.
Key Features of .bnb Domains
- Simplify Wallet Addresses: Replace your lengthy public key with a clean
.bnbhandle. - Own Your Digital Identity: Your domain is stored as an NFT in your wallet — fully under your control.
- Customizable Records: Set blockchain addresses, IPFS hashes, avatars, and more.
- Interoperable Across dApps: Use your
.bnbname in wallets, exchanges, DeFi platforms, and NFT marketplaces. - Permanent Ownership: As long as you renew before expiration, you retain full rights.
These features make .bnb domains essential tools for anyone serious about participating in the BNB Chain ecosystem.
Step-by-Step Guide: How to Register a .bnb Domain
Registering a .bnb domain is straightforward — but timing and preparation matter. Follow these steps carefully to secure your preferred name.
Step 1: Connect Your Wallet
Go to the official SPACE ID platform at app.space.id and click “Connect” in the top-right corner. You'll need a Web3 wallet like MetaMask or Trust Wallet.
Ensure your wallet is set to the BNB Smart Chain (BSC) network. Since SPACE ID operates on BNB Chain, using any other network will prevent successful transactions.
👉 Get started with a secure Web3 wallet and claim your .bnb name now.
Step 2: Search for Availability
Enter your desired domain name in the search bar (e.g., alice.bnb). The system will instantly check availability:
- If it shows "Available", you're good to proceed.
- If it shows an error or "Taken", try another variation.
During the phased rollout period, only 300 domains are released per day, refreshing daily at 13:00 Beijing Time (1:00 AM ET) from September 7 to September 11. If you see “Registration Limit: 300/300”, come back the next day.
Step 3: Request Registration
After confirming availability, click "Register" to enter the registration page. Choose your registration period — minimum 28 days — and review the estimated cost in BNB.
Click "Request" to initiate the first transaction. This locks your claim temporarily and prevents others from registering the same name while you complete payment.
⚠️ Note: The request process may take up to 30 seconds to confirm on-chain.
Step 4: Complete Payment
Once the request transaction confirms (you’ll see a green checkmark ✓), return to the dashboard and click "Register" again to finalize the payment — this is the second and final transaction.
Important: You must complete this second step within 7 days of requesting registration. Otherwise, your reservation expires, and you’ll need to restart the process.
Step 5: Manage Your Domain
Congratulations! You now own a .bnb domain. Click "Manage Profile" to customize settings:
- Link multiple cryptocurrency addresses (BTC, ETH, USDT, etc.)
- Upload an avatar
- Set an IPFS-hosted website
- Configure social media links
Your .bnb domain becomes a unified identity hub across Web3.
Frequently Asked Questions (FAQ)
Q: Is the .bnb domain an NFT?
A: Yes. Each .bnb domain is represented as an ERC-721-compatible NFT stored directly in your wallet, giving you full ownership and control.
Q: Can I transfer or sell my .bnb domain?
A: Absolutely. Since it's an NFT, you can transfer it to another wallet or list it for sale on NFT marketplaces like OpenSea or Blur.
Q: How much does a .bnb domain cost?
A: Pricing depends on name length and demand. Shorter names are typically more expensive. The minimum registration period is 28 days, with fees paid in BNB.
Q: What happens if I don’t complete registration within 7 days?
A: If you don’t complete the second transaction within 7 days, your reservation is canceled, and the domain becomes available for others to register.
Q: Can I use my .bnb domain outside BNB Chain?
A: While currently optimized for BNB Chain, SPACE ID plans cross-chain integration. Future updates may allow use on Ethereum, Polygon, and other networks.
Q: Are there renewal fees?
A: Yes. Like traditional domains, .bnb domains require periodic renewal. You’ll receive reminders before expiration.
