The SUI wallet has been rebranded to Slush wallet. That's why you might not be able to find it under the old name.

If you can’t find your Sui wallet on your devices or on the official Sui website, don’t worry—there haven’t been major changes to how Sui wallets work, but there have been a few updates and new names that might be causing confusion. The original Sui Wallet browser extension has now been renamed to "Sui Wallet by Mysten", and it may appear differently in your extensions list or app store depending on your browser. If you were using the wallet through a browser, make sure your extension is still installed and enabled, or check if it was removed during a browser update. Also, make sure you’re looking for the right app icon or name—some users confuse it with other wallets like Surf Wallet, Ethos Wallet, or Martian, which also support the Sui network but are separate tools.

If you backed up your recovery phrase (seed phrase), you can easily import your wallet into the current version of Sui Wallet by Mysten or even into compatible third-party wallets. To be safe, always double-check the extension or app is the official version from https://sui.io or directly from the Chrome Web Store.

You can get the latest download link and wallet info from the official docs here: https://docs.sui.io/wallets/sui-wallet. If your wallet was created using zkLogin, remember that it won’t have a seed phrase, and you’ll need to log back in using the same Web2 method (like Google or Discord).
