SPACE ID is emerging as a leading force in Web3 identity infrastructure, offering a universal name service network and a seamless platform for managing digital identities across multiple blockchains. Through its powerful suite of tools, including the ID token, SDKs, and a multi-chain name service, SPACE ID is redefining how users interact with Web3 domains.

A Universal Identity Layer for Web3

At its core, SPACE ID simplifies Web3 domain management by providing a one-stop platform to discover, register, trade, and manage domains across blockchains. Much like DNS in the traditional internet, SPACE ID brings readable names to Web3 addresses—think username.bnb or handle.arb instead of complex wallet strings.

The platform enhances usability with its Web3 Name SDK & API, giving developers an easy way to integrate domain and identity functions into their dApps. It also supports reverse resolution and multi-wallet linking, making it easier to build cross-chain, identity-rich applications.

The ID Token: Fueling the Ecosystem

The native ID token underpins all activity within the SPACE ID ecosystem. It serves three key purposes:

• Staking: Users who stake ID receive discounts on both domain registrations and fees in the Domain NFT Marketplace.

• Payments: ID is used to pay for services within the SPACE ID ecosystem and integrates into the Name SDK for third-party applications.

• Governance: Holders participate in DAO proposals, helping shape the platform’s future development.

With a total supply of 2 billion tokens, ID is distributed across early adopters, the core team, and public investors. The token model emphasizes sustainability and incentivizes community participation through airdrops, exclusive features, and staking benefits.

Real-World Use Cases and Developer Appeal

SPACE ID goes beyond domain names—it’s a foundational layer for decentralized identity. By offering a multi-chain name service, the platform enables unified identity management across Ethereum, BNB Chain, Arbitrum, and other networks.

Its developer-friendly SDK and API streamline integration, making it easier to incorporate human-readable addresses and identity features into DApps, wallets, and DeFi platforms. For end users, the system’s intuitive interface removes the technical barrier traditionally associated with Web3.

The grant program further fuels adoption by supporting projects that align with SPACE ID’s vision, encouraging builders to innovate within its growing ecosystem.

Key Milestones and Evolution

SPACE ID has marked several major milestones in its development:

• Launch of its universal name service network, laying the groundwork for cross-chain identity infrastructure.

• Release of the Web3 Name SDK & API, empowering developers to integrate identity features seamlessly.

• Introduction of the ID token, enabling governance, staking, and payments.

• Launch of SPACE ID 3.0, a major upgrade that brought improved UX, deeper multi-chain support, and a more robust ecosystem.

• Strategic partnerships and ecosystem integrations have helped scale adoption and technical capabilities.

These advancements collectively position SPACE ID as an essential identity layer in the Web3 stack.

Founding Team and Vision

SPACE ID was co-founded by Xu Nuo and Xu Wei, who set out to address the fragmented nature of identity across blockchain networks. While specific biographical details are limited, the founders’ vision is reflected in the platform’s ambition to unify decentralized identities under one universal naming system.

Conclusion

SPACE ID is more than a domain registrar—it’s a powerful infrastructure layer for Web3 identity. With a robust tech stack, multi-chain support, and the ID token driving utility and governance, SPACE ID is positioned to become the standard identity protocol in decentralized applications. As the ecosystem grows and adoption deepens, SPACE ID could play a central role in simplifying how we manage identity in the blockchain world.

Unity Wallet supports Space ID on both the Ethereum and Binance Smart Chain blockchains.
