.sui
Is .sui a real TLD? Who’s applying to run it?
.sui is not contested. One application for it is on ICANN’s Reveal Day list, as of 7 October 2026. It is Red Rock (Cayman) Foundation.
A web address ending for the Sui crypto community: meaningful to people building and trading there, with little pull beyond it.
sui ecosystem builders, wallets, dapps, and crypto-native users who already hold .sui identities on-chain and want a matching public web address
Announced via the applicant's official X account (@suinsdapp). Sui Naming Limited operates SuiNS, the Sui blockchain's name service, whose on-chain identities already use the .sui ending.
The 2012 applications making the most similar bet. Chosen by AI from every string in that round, without being told what happened to any of them.
Same bet as .sui: a coined platform name owned by the entity that built the platform, where the string only pays off if a third-party ecosystem of builders and users adopts it as their own primary identity rather than the owner using it as a marketing channel.
A single-steward, non-descriptive platform/runtime name pitched as the namespace for a developer community that exists independently of the steward's consumer brand — the same 'protocol-as-namespace' wager .sui makes, minus the token-holder governance layer.
Shares the narrow slice where a platform's end users hold handles inside the platform owner's namespace (gamertag ≈ wallet name), but it is a closed consumer product brand rather than an open network others build businesses on, so the identity is granted rather than owned.
What a .sui domain is
.sui is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, filed under Crypto. One application for it is on ICANN’s Reveal Day list.
Is the .sui domain extension real yet?
.sui is not yet a domain extension you can register: nothing resolves under it, and no registrar sells names in it. It is a string applicants have put forward in the ICANN 2026 new gTLD round, the process that decides whether it becomes one.
When can you buy a .sui domain?
You can’t yet. A .sui name can only be registered once the string is delegated (added to the DNS root) and its registry opens. Last round's closest parallel to .sui was .android, delegated on 12 November 2014.
Is .sui a real TLD?
Not yet. .sui is not in the DNS root, so nothing resolves under it. It’s here because .sui is on ICANN’s Reveal Day list of applied-for strings. Every entry on this page links to its source.

- Band chosen: 30-49, usable but limited. Not in the band below (10-29) because demand is not merely event-driven: SuiNS is the primary name service on the Sui blockchain and its on-chain identities already use the .sui ending, so a real user base with genuine identity use predates the DNS application, and the applicant, Sui Naming Limited, is the company behind that service, which supports adoption likelihood. Not in the band above (50-69) because the demand is confined to a single chain's ecosystem: outside it the string reads as a brand-tied crypto label whose adoption needs explaining, and sustained DNS-side demand is unknown. By analogy (flagged as analogy), blockchain naming systems have tended to see registration surges that track the host chain's momentum and cool when it fades, and single-ecosystem endings have historically shown thin aftermarkets relative to broad crypto or tech namespaces; scale figures for Sui or SuiNS are unknown and I assert none. Serious use as a primary identity is plausible for Sui-native projects but unlikely to extend to general tech or commerce buyers within 5 years. Main market uncertainty: whether the Sui chain retains developer and user momentum over the next 5 years, and whether existing on-chain .sui holders convert into paying DNS registrants rather than staying purely on-chain.
