If you still reach Sui assets through Suiet, the holding question is whether you can open those accounts after the wallet software goes away. This is not a report of missing coins.
On November 11, 2026, TechFlow reported that Sui’s official account had reminded users the Sui ecosystem wallet Suiet would stop support after November 14. Sui’s advice, as relayed in that report, was to back up the mnemonic phrase or private key of every account immediately and not to disclose those secrets to anyone. Assets remain on the Sui chain. Importing an account into another Sui wallet was described as the way to keep access.
The same report said Sui also forwarded a migration guide from the Slush wallet and said that, after the switch, the address and the assets stay the same. That statement is about the on-chain account continuing, not a claim that a different wallet removes every custody risk.
TechFlow also noted an earlier announcement from the Suiet team: it had decided to stop developing and maintaining Suiet, with API service kept until November 14, 2026 so users could migrate. Suiet had no mobile app, and its Chrome Web Store extension was expected to be removed soon. No removal date beyond “soon” was given.
A backup has to serve three different jobs at once:
- Accessibility. The phrase or private key is what lets you import that account elsewhere. The reported notice asked users to back up each account, not only one.
- Confidentiality. Anyone who obtains the mnemonic or private key can move the assets. The reminder was not to give it to anyone, including people offering to “help” with the move.
- Redundancy. The report did not prescribe how many copies to keep or which storage product to use. A copy only helps if it stays under your control. Sharing one for convenience weakens confidentiality.
Checks that follow from the reported notice:
- List the Suiet accounts you actually use and back up the mnemonic or private key for each one before support ends.
- Keep those secrets to yourself. Do not paste them into chats, forms, or support requests.
- After importing into another Sui wallet, confirm the address is the one you already use. The Slush guide forwarded by Sui said the address and assets remain unchanged after the switch.
- Treat the expected Chrome Web Store removal, and the lack of a Suiet mobile app, as reasons not to wait. They are not signs that balances left the chain.
The report did not quantify losses, describe an exploit, or say user funds had been taken. What it described was a planned end of Suiet’s development, maintenance, API support through November 14, 2026, and store listing.
