Suiet Wallet to Shut Down as API Services End After Nov. 14

Another Sui wallet is heading for the exit. Suiet, a self-custodial browser extension wallet built for the Sui blockchain, said in a notice that it will stop updating and supporting the wallet, and its API services end after Nov. 14.

User funds are not at risk. Assets sit on the Sui chain, not in the extension, so the job for holders is simple: back up the recovery phrase or private key and import it into another compatible wallet. The Chrome extension is expected to be pulled shortly after the API services go dark, and Suiet never offered a mobile app. There is no phone fallback. If you never wrote down your seed, now is the time.

What users should do

Scallop and Slush are the named alternatives, and the official Sui team has been walking users through migration paths. Confirm that restored addresses match the old ones before you deactivate the extension.

Also expect scammers. Treat any unsolicited "migration tool" link, or any support message asking for a recovery phrase, as hostile.

Another exit from Sui

Suiet is the latest in a run of departures. The Suiball hardware wallet project announced its closure this week, with heightened security concerns cited. Phantom ended Sui support in September. DeFi project Full Sail shut down after a Switchboard-related security incident that caused about $91,000 in losses, as we reported in our coverage of the Full Sail shutdown.

The numbers behind the chain are mixed. Sui DeFi TVL sat at roughly $413 million to $417 million on Wednesday, depending on the data source, down more than 22% over the past month. Token Terminal data shows Sui averaged about 128,000 daily active users in October, down about 79% from 601,000 in November 2025. Transactions, though, rose to 324 million from 101 million over the same stretch. More transactions do not necessarily mean more users.

Reliability has been a drag too. Sui has had four network outages in 2026, about 22 hours of combined downtime, including roughly six hours in January and three more on May 28 and 29, tied to software bugs including problems from a network update. The Sui Foundation said no user funds were at risk in the May disruptions. For comparison, Solana has had no network-wide outage since February 2024, and Aptos last reported a mainnet outage in October 2023.

Economics, not a protocol flaw

Kadan Stadelmann, former CTO of Komodo Platform, argues the exits are about money rather than code:

"Sui's problems seem to mostly be of an economic nature resulting from expensive engineering costs and low user volume rather than protocol failures"

He added that "Multi-chain wallets have expansive attack surfaces, and Sui's approach adds costs for vendors who can take their business to less capital intensive chains."

Stadelmann says no flaw in Sui's core design has been found. That framing matters for traders. The risk here is attrition: fewer wallets, fewer integrations and thinner user activity. Not a threat to coins already on chain, but not a great look for liquidity either.
