SPACE ID review
A multi-chain service for finding, managing and resolving Web3 domain names.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SPACE ID brings Web3 domain discovery, registration, trading and management together for people and teams working with blockchain-based names. Its web application aggregates supported name services, including names such as .bnb, .arb and .eth. The platform is suited to users who need names across multiple networks, as well as developers integrating name resolution into other products.
The core offering covers the domain lifecycle: search across supported TLDs, register with a selectable duration, trade names in a dedicated marketplace, and manage ownership, records, primary names and renewals. It supports 23 blockchains and two-way resolution: names can resolve to cryptocurrency addresses, and addresses can resolve to primary domain names. Identity features are included, but web3 website hosting is not, so buyers seeking a hosting service alongside domain management should look elsewhere.
For developers, SPACE ID offers a Web3 Name SDK and HTTP API for integrations. Registration fees vary according to domain length, registration duration and network gas, so costs depend on the name and transaction rather than a fixed published starting price. Documentation is the listed support channel. SPACE ID is a fit for buyers who value multi-chain name search, management and resolution, or need programmatic access; it is less suited to those prioritizing bundled website hosting or support beyond documentation.
