Suiet, a browser extension wallet for the Sui blockchain, is shutting down. The development team will end all maintenance and support, with API services terminating after November 14, 2026.
The closure follows a period of declining activity in Sui's decentralized finance sector. Sui's total value locked in DeFi protocols dropped more than 22% over the previous month, reaching approximately $416.92 million as of November 11, 2026.
What Suiet Users Should Do
User assets remain on the Sui blockchain itself, as wallets do not directly hold cryptocurrencies. The Suiet team is advising users to back up their recovery phrases or private keys immediately.
These credentials can be imported into compatible wallets to restore access to balances and transaction history. Alternative wallets mentioned as options include Scallop and Slush, with the official Sui team providing guidance on migration paths.
Users should verify that restored addresses in their new wallet match those in Suiet before deactivating the extension. The Chrome extension is expected to be removed from the store shortly after API services end. Since Suiet never offered a mobile application, the browser extension was the only access point.
Users are advised to be cautious of unsolicited migration tools or messages requesting recovery phrases, as legitimate services do not require such information to be transmitted.
Broader Ecosystem Challenges
Suiet's shutdown is part of a broader pattern of infrastructure exits from the Sui ecosystem. Phantom, a multichain wallet, withdrew Sui support on September 24, 2026. On November 11, 2026, the Suiball hardware wallet project also announced its shutdown, citing heightened security concerns.
These exits suggest tightening infrastructure support as the ecosystem experiences reduced user activity and capital deployment.
