The Suiet wallet, one of the longer-running self-custodial wallets on the Sui blockchain, is shutting down and will switch off its API services after Nov. 14, leaving users until the end of the week to back up their accounts and move to another wallet. The team said in a notice on its website that it has decided to “sunset Suiet and bring development and maintenance of the wallet to an end.” It is the second Sui wallet project to close this week.
What Suiet said
The notice gives no reason for the decision. It says the team will keep the API running through Nov. 14 “to give you time to transition to another wallet,” and that the Suiet extension on the Chrome Web Store “will also be sunset soon.” Suiet has no mobile apps.
Funds are not at risk from the shutdown itself, because Suiet never held them. “Your assets exist on the Sui blockchain, and discontinuing Suiet will not move or delete them,” the team wrote. The problem is access. Once the API goes offline, the wallet “may no longer reliably display balances, send transactions, or connect to applications,” and the team said users should not rely on it after the transition period.
The Sui account itself amplified the warning. Sui said on Wednesday that support for Suiet ends after Nov. 14 and told users to “back up each account’s recovery phrase or private key now,” adding that their assets remain on Sui and can be imported into another wallet.
What users need to do
The steps in Suiet’s notice are straightforward but easy to get wrong under time pressure:
- Save the recovery phrase or private key for every account. Accounts imported into Suiet separately may need their own backups.
- Restore those accounts in another Sui wallet through its official import flow, or create a new wallet and transfer assets to it, which incurs normal network fees.
- Check that the restored address matches and that balances, staking positions and assets held in apps are visible before uninstalling Suiet or clearing its data.
Suiet also warned users never to share a recovery phrase with anyone claiming to represent the team. Wallet shutdowns tend to draw phishing attempts that pose as migration help, so the deadline is a good moment to be suspicious of any message offering to “restore” funds.
A run of exits from Sui
The closure follows hardware wallet project Suiball, which said early Wednesday that it was shutting down before shipping a single device. Suiball said the Sui Foundation had decided the risk of backing a hardware wallet was too high. Earlier, Phantom ended support for Sui on Sept. 24, telling users their assets stayed on chain and could be moved to another wallet.
Cointelegraph, which reported the Suiet closure on Wednesday, also pointed to the shutdown of DeFi project Full Sail and to Token Terminal data showing Sui averaged about 128,000 daily active users in October, down from 601,000 in November 2025.
The money on the network has been shrinking too. Sui’s total value locked was about $412 million on Thursday, according to DefiLlama, down roughly 22% from $532 million a month earlier and around 71% below the $1.44 billion it held a year ago. Transactions tell a different story: Token Terminal counted 324 million in October, more than three times the November 2025 figure, Cointelegraph reported, though more transactions do not necessarily mean more users.
Why it matters
For a chain competing for users, wallets are the front door. Each one that closes pushes holders toward a smaller set of options, and for Sui that increasingly means Slush. Phantom’s help page describes it as the Sui Foundation’s recommended wallet, and Sui shared a Slush switching guide alongside its Suiet warning. The wallet closures so far have come with notice periods and clear instructions, and because these wallets are self-custodial, users keep control of their assets as long as they hold their keys.
The question for the next few weeks is whether more Sui projects follow, and whether the Sui Foundation says anything about support for the builders who remain. Neither Suiet nor the foundation had responded to Cointelegraph’s requests for comment at the time of its report.
FAQ
Will I lose my coins when Suiet shuts down?
No. Suiet is self-custodial, so assets stay on the Sui blockchain. You need your recovery phrase or private key to reach them from another wallet.
What happens after Nov. 14?
Suiet’s API services stop. The extension may stay installed, but the team said balances, transactions and app connections may no longer work reliably.
Is the Sui network affected?
No. The shutdown concerns one wallet app. The Sui blockchain and other Sui wallets continue to operate.
