Suiet, a browser extension wallet built for the Sui blockchain, is closing. The team will stop all development and maintenance, and its API services end after November 14, 2026.

Sui’s DeFi total value locked has dropped more than 22% over the past month, and Suiet is the latest in a series of service providers heading for the exits.

What Suiet users need to do

User funds are not going anywhere. Assets stay on the Sui chain, because a wallet never actually holds coins.

The Suiet team is urging users to back up their recovery phrases or private keys now. Those credentials can then be imported into a compatible wallet to restore access to balances and transaction history.

The Chrome extension is expected to be pulled shortly after the API services go dark. Once that happens, anyone who never wrote down their recovery phrase may find the process considerably less relaxing.

Suiet never offered a mobile app, so there is no phone-based fallback. The extension is the only door, and it is closing.

Users should confirm that the restored addresses in their new wallet match the old ones before deactivating the Suiet extension.

Alternatives named as options include Scallop and Slush. The Sui official team has been actively informing users about migration paths and compatible wallets.

A pattern of exits across the Sui ecosystem

Phantom, one of the better-known multichain wallets, withdrew support for Sui on September 24, 2026. For users who held Sui assets there, that was the first notable signal that infrastructure support was thinning.

Then on November 11, 2026, the Suiball hardware wallet project announced its own shutdown, citing heightened security concerns.

Meanwhile, as of November 11, 2026, Sui’s DeFi TVL stood at approximately $416.92 million, after falling more than 22% from the previous month.

TVL measures how much capital users have parked in a chain’s lending, trading, and yield protocols. When it falls by more than a fifth in a month, it suggests users are withdrawing funds, asset prices are falling, or both.

What this means for Sui users and investors

For current users, the immediate priority is practical. Anyone holding assets in Suiet should secure their recovery phrase or private key and move to a supported wallet before November 14, 2026.

Shutdowns also tend to attract opportunists. Users should be careful with any unsolicited link, “migration tool,” or support message asking for a recovery phrase, since no legitimate service needs one sent to it.

There are some offsetting factors. The official Sui team is engaging directly with users on migration, and alternatives like Scallop and Slush give stranded Suiet users somewhere to land.

For now, the network is running, the assets are safe, and the deadline is November 14. Users who back up their keys will be fine.
