Suiet Wallet Will Shut Down as Sui DeFi TVL Falls 22% in a Month

Suiet, a browser extension wallet built for the Sui blockchain, will stop all development and maintenance, with its API services ending after November 14, 2026. The Chrome extension is expected to be pulled shortly after the API cutoff. The shutdown makes Suiet the third notable infrastructure exit from the Sui ecosystem in under two months.

The closure lands against a cooling market. Sui's decentralized finance total value locked stood at approximately $416.92 million as of November 11, 2026, after dropping more than 22% over the previous month, according to the figures cited in the announcement's coverage. TVL measures the capital users have parked in a chain's lending, trading and yield protocols. A decline of more than a fifth in thirty days signals that users are withdrawing funds, that asset prices are falling, or both.

Phantom, one of the better-known multichain wallets, withdrew support for Sui on September 24, 2026 — the first clear sign that infrastructure support was thinning. On November 11, 2026, the Suiball hardware wallet project announced its own shutdown, citing heightened security concerns. Suiet is the latest in that series of exits.

What do Suiet users need to do before November 14?

User funds are not at risk from the closure itself. A wallet never actually holds coins; assets remain on the Sui chain. The Suiet team is urging users to back up their recovery phrases or private keys now, before the extension disappears.

Those credentials can be imported into a compatible wallet to restore access to balances and transaction history. The team advises users to confirm that the restored addresses in the new wallet match the old ones before deactivating the Suiet extension.

The timing matters because Suiet never offered a mobile app, so there is no phone-based fallback. The extension is the only access point, and once the Chrome listing is pulled, anyone who never wrote down a recovery phrase faces a considerably harder recovery path.

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

Why wallet shutdowns attract scammers

Shutdowns of this kind tend to attract opportunists. Users should treat any unsolicited link, "migration tool" or support message that asks for a recovery phrase as fraudulent, since no legitimate service needs one sent to it. The standard practice — import keys into a self-selected, verified wallet application — never requires sharing the phrase with a third party.

There are offsetting factors for the ecosystem. The Sui team is engaging directly with users on migration, and the named alternatives give stranded Suiet users somewhere to land. The network itself continues to run, and on-chain assets remain intact regardless of which client software reads them.

What happens next?

The operative deadline is November 14, 2026, when Suiet's API services go dark and the Chrome extension follows. For Sui's broader market structure, the question is whether TVL stabilizes near the $416.92 million mark or whether further infrastructure exits compound the withdrawal pressure that has already cut capital locked by more than a fifth in a single month.
