About SPACE ID
SPACE ID is a unified platform for managing decentralized identities, enabling users to discover, register, trade, and manage Web3 domain names across multiple blockchains. By bridging the gap between traditional Web2 user experiences and the emerging world of Web3, SPACE ID empowers users with intuitive tools to manage their digital presence.
At its core, SPACE ID is building the infrastructure for a truly universal naming service. It combines support for Top-Level Domains (TLDs) like .bnb, .eth, .arb, .inj, .sei, .taiko, and .g, with SDKs and APIs that make integration across dApps and wallets seamless. As decentralized identity becomes a pillar of Web3, SPACE ID is strategically positioned to serve both end users and developers across the crypto ecosystem.
SPACE ID was created to address a critical pain point in the blockchain space: managing multiple domain identities across various chains. While Web3 has unlocked new ways to represent ownership and digital presence, the experience of handling domains remained fragmented, complicated, and overly technical. SPACE ID offers a unified and user-friendly solution.
The platform provides a seamless interface for domain registration, trading, management, and integration across multiple supported blockchains. Initially focusing on BNB Chain with the introduction of the .bnb Name Service, SPACE ID quickly expanded to multichain, supporting Binance Smart Chain (.bnb), Ethereum (.eth), Arbitrum (.arb), Injective(.inj), Sei(.sei), Taiko(.taiko), Gravity (.g) and other 24+ chains. Its robust backend and the SPACE ID 3.0 upgrade introduced a permissionless framework, allowing anyone to launch their own TLDs without the need for technical expertise.
With its Web3 Name SDK and API toolkit, developers can integrate naming functionalities into their dApps within 30 minutes. These features are already adopted by over 200+ partners, including well-known platforms like BscScan, MetaMask, and DappRadar. The SDK enables domain name resolution and reverse resolution for supported TLDs.
The SPACE ID ecosystem offers not only tools for individuals and developers, but also infrastructure for communities and projects to launch, manage, and monetize their own decentralized domain names. Features like integrated NFT marketplaces, customizable domain records (including avatars, social handles, and multi-chain addresses), and real-time domain discovery tools make the platform a full-service solution.
In comparison to other blockchain domain providers such as Ethereum Name Service (ENS), Unstoppable Domains, and Freename, SPACE ID differentiates itself with its cross-chain capabilities, integrated marketplace, and developer-focused design. Its mission is not just to offer domains, but to serve as the foundational identity infrastructure for all of Web3.
SPACE ID provides numerous benefits and features that make it a standout project in the Web3 domain and identity landscape:
- Multi-Chain Domain Management: Support for .bnb, .eth, .arb, .inj, .sei, .taiko, and .g, and more — all accessible and manageable from one dashboard.
- Integrated NFT Marketplace: A dedicated secondary marketplace for domain NFTs powered by SPACE ID, offering a streamlined experience for trading and discovery.
- One SDK & API for All: The Web3 Name SDK and Web3 Name API enable seamless integration with over 200+ dApps. Developers can easily query domain data, perform reverse lookups, and implement automatic domain resolution — significantly reducing development time and enhancing user experience. Full documentation is available here.
- Customizable TLD Launch Toolkit: Communities can launch their own TLDs using the SPACE ID 3.0 infrastructure — no development required.
- Universal Payment ID System: Enhances the CEX deposit process by replacing complex wallet addresses with human-readable IDs like name@binance, simplifying user experience for centralized exchange users.
Getting started with SPACE ID is quick and intuitive for both individual users and developers. Here's how to begin using the Web3 identity platform:
- Create an Account: Visit SPACE ID and connect your wallet (such as MetaMask, Binance Wallet WalletConnect and many others). There is no separate sign-up — your Web3 wallet acts as your identity.
- Search and Register a Domain: Use the search feature on the homepage to look up available domain names. You can register .bnb, .eth, .g, and more.
- Manage Your Domain: Use the dashboard to set records like avatars, social profiles, and multi-chain wallet addresses. You can also renew, transfer, or update domain ownership.
- Trade Domains: Access the integrated domain marketplace to buy or sell names. All domain NFTs are listed in an interface that aggregates listings from major marketplaces.
- Use Your Payment ID: Register a Payment ID (e.g., jane@bnb) that maps to all your on-chain addresses. Use it to receive funds or link across exchanges and wallets.
- Developer Integration: Visit the SPACE ID Docs to explore the Web3 Name SDK and API. Integrate identity resolution into your dApp with just a few lines of code.
- Join the Community: Follow updates on Twitter, ask questions in Discord, and explore guides on Medium.

SPACE ID FAQ
- SPACE ID bridges the complexity gap between Web2 and Web3 by introducing a Payment ID system and email-based sign-ins via ZK Email. Users can register a human-readable identity like alex@bnb that maps to multiple wallet addresses, eliminating the need to remember or manage long crypto strings. This allows newcomers to interact with decentralized apps using familiar formats — all without deep blockchain knowledge. 
- Yes. Once you register a SPACE ID domain such as yourname.bnb, it functions as a cross-chain identity that resolves to the correct address depending on the blockchain you're using. This works not only within wallets, but also across supported exchanges. It significantly reduces the risk of sending assets to the wrong address and is compatible with major platforms integrated via the SPACE ID ecosystem. 
- The SPACE ID Web3 Name SDK acts as a powerful backend tool that enables dApps to integrate decentralized identity resolution in just 30 minutes. With built-in support for .bnb, .eth, .g, and custom TLDs, developers can implement domain-based logins, address mapping, and reverse name lookups with minimal setup. Over 200 partners have already used it, reinforcing SPACE ID's vision for an interoperable Web3 naming standard. 
- SPACE ID 3.0 introduces a permissionless name service protocol that supports horizontal expansion of TLDs. The system is designed for scalability via modular SDKs and APIs, allowing seamless onboarding of new chains and domain providers. The infrastructure supports dynamic resolution and contextual address mapping across multiple chains, making SPACE ID a scalable, future-proof solution for the decentralized identity layer. Learn more in the official documentation. 
- Absolutely. Through SPACE ID 3.0, any community, project, or DAO can launch its own Top-Level Domain (TLD) using the SPACE ID platform — without needing development experience. These communities can control pricing, minting, and royalties, enabling monetization directly through domain issuance and secondary marketplace trading. It’s a decentralized, scalable path to revenue generation and brand identity in Web3.
