What is SPACE ID?
SPACE ID is a Web3 name service that runs .bnb on BNB Chain and .arb on Arbitrum and offers a toolkit for communities to launch their own top-level domains. Its developer docs say the registration fee depends on name length and duration, and names are rented by the year.
How SPACE ID works
Every SPACE ID name is a domain NFT that sits in your wallet.
The registration docs describe three steps: check that the label is free, query the rent price for the chosen number of years, then call the register function with that fee. The .bnb registry runs on BNB Chain (chain ID 56), .arb on Arbitrum One (42161) and .eth on Ethereum (chain ID 1). On Ethereum the SDK adds a commit transaction and a 60-second wait before the register call.
After you register, the My Domains page lets you set a record address, pick one primary name per network, transfer ownership and extend the registration. Only the registrant can transfer a name, and the record address has to be set before the name can become your primary. The docs say .bnb is built on the ENS design and is integrated with more than 100 projects, including BscScan and Trust Wallet.
The built-in marketplace pulls listed names from OpenSea, Element and ENSVision. Offers can only be made and received in WETH or WBNB, not in native ETH or BNB. Communities that want their own top-level domain fill in a form with SPACE ID, and the Web3 Name SDK then resolves that TLD next to .eth, .lens, .crypto, .bnb and .arb.
How to start with SPACE ID
- You need MetaMask or a WalletConnect wallet on the same chain as the name you want.
- Registration takes two transactions, Request and Register, and the minimum term is one year.
- The price shown in the app grows with the number of years and includes estimated gas.
- A shopping cart can hold names from several chains, but you can only check out names from one chain at a time.
- For referral links, you must first set a primary name; referrers earn up to 15% of invitees' .bnb registration fees.
SPACE ID fees and limits
- SPACE ID does not publish a fixed rent table: the fee is quoted per name and depends on length and years, and the .bnb page says a registration costs under $10 on average.
- The marketplace guide says trades normally carry a 1.5% service fee, while also advertising a limited-time zero fee with no end date.
Staking the ID token gives discounts on marketplace fees and registrations, per the token page.
Risks to know before using SPACE ID
- Names are rented: after a name expires, only the previous registrant can extend it during a 90-day grace period, and after that anyone can register it.
- The Terms of Use, effective September 11, 2024, belong to SPACE ID Labs ltd. and let it change, suspend or shut the site without notice.
- A section of those terms still contains text about buying from Unstoppable Domains with no renewal fees, which conflicts with SPACE ID's own yearly rent.
- Web3 names also need browser plugins or network changes to resolve on normal websites, per the same terms.
