About .sui

The .sui domain extension is built around the name of the Sui public blockchain network and its native SUI token. It suits the developers, validators and builders who work on Sui, and the people who follow it.

Visitors to a .sui address can tell right away that it belongs to the Sui community. The name also ties to the Japanese reading of "sui" as water, which shows up in the network's water imagery. This top-level domain gives that community a home in the regular Domain Name System.

You might use it for websites, email, applications and other services tied to Sui. Developers can publish projects built with Move, validator operators can list their nodes, and creators can point people to their work. A shared name makes Sui-related resources easier to find.
