SuiNS review
A Sui-focused naming service for wallet resolution, reverse lookup, and subnames.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SuiNS is a decentralized naming service for people and applications on the Sui blockchain. It lets users register human-readable .sui names, resolve them to wallet addresses, and use names for on-chain transfers. Names are represented as NFTs and can carry identity settings such as a default name and an associated NFT avatar. Its focus is useful for Sui users who want a recognizable name rather than relying only on a wallet address, but it is not a multi-chain naming service.
Its feature set covers both directions of lookup: a name can resolve to a wallet address, and an address can be reverse-resolved to a name. Owners can link a name to a target wallet address, set a default name for an address, associate an NFT avatar, or link to an IPFS-hosted website. Developers can use documentation for on-chain and off-chain resolution, reverse lookup, and application-specific subnames. That makes SuiNS relevant not only to individual identity but also to applications that need namespaced subnames. The tradeoff is ecosystem breadth: the service supports one blockchain and one extension, so users seeking names across several chains should look elsewhere.
SuiNS is a paid service without a free plan. According to its user guide, registration prices are displayed dynamically in SUI for each searched name, and registrations run for one to five years. That structure means buyers should check the specific name and term before deciding; there is no single static price to use as a general estimate. SuiNS is open source and available on web and through an API, with cloud and browser-extension deployment options. Documentation is the listed support channel. Choose it for Sui-specific name resolution and identity features; it is a narrower fit for buyers who need broader chain coverage or a different support channel.
