By Suiet, a self-custodial cryptocurrency wallet built for the Sui blockchain, is shutting down its services, with API support scheduled to end after November 14, 2026. The closure adds to a series of departures from the Sui ecosystem as decentralized finance (DeFi) liquidity and user activity decline sharply.
Sui’s total value locked (TVL) fell more than 22% over the past month to approximately $413 million on November 11, according to DefiLlama. Meanwhile, Token Terminal data indicates that average daily active users dropped to around 128,000 in October, compared with 601,000 in November 2025, a decline of nearly 79%.
The wallet’s closure follows the withdrawal of other infrastructure providers, including Suiball and Phantom, raising questions about whether Sui’s transaction growth is translating into sufficient economic activity to sustain its ecosystem.
What Happens to Suiet Users After November 14?
Suiet confirmed that it will discontinue wallet development and maintenance while keeping its API services operational through November 14 to allow users to migrate.
The company said its Chrome browser extension will also be discontinued, although it did not specify a removal date.
Because Suiet operates as a self-custodial wallet, customers retain ownership of their private keys and blockchain assets. The shutdown will not automatically transfer, freeze or delete funds held on Sui.
However, once API services are discontinued, existing installations may no longer reliably display balances, submit transactions or connect to decentralized applications.
Suiet advised customers to back up the recovery phrase or private key associated with each account and import their accounts into another compatible Sui wallet before the deadline. Users should verify their wallet addresses and access to assets, including staking positions, before removing the original extension.
The distinction between wallet infrastructure and blockchain custody is important. Users who securely retain their recovery credentials can continue accessing their on-chain assets through another compatible application, even if Suiet’s software becomes unusable.
Investor Takeaway
Suiet’s shutdown does not represent a loss of customer assets or a failure of the Sui blockchain. The immediate risk is operational: users who have not backed up their recovery credentials could lose practical access to their holdings when the wallet’s supporting services disappear.
Why Are More Projects Leaving the Sui Ecosystem?
Suiet’s departure follows the November 10 closure announcement from Suiball, a Sui-focused hardware wallet project. Suiball said it would shut down and refund pre-orders, adding another infrastructure withdrawal to the ecosystem.
FinanceFeeds previously covered Suiball’s closure alongside recent cryptocurrency security incidents, including the project’s account of concerns surrounding hardware wallet risks. That account had not been independently confirmed by the Sui Foundation.
Multi-chain wallet provider Phantom also discontinued Sui support in September, while decentralized finance project Full Sail ceased operations following a Switchboard-related security incident that reportedly resulted in approximately $91,000 in losses.
These developments have occurred alongside deteriorating activity indicators. Although Sui’s DeFi TVL has fallen substantially, the network has continued processing large transaction volumes.
Token Terminal data indicates that Sui processed approximately 324 million transactions in October, compared with 101 million in November 2025. That represents an increase of roughly 221%, despite the sharp decline in average daily active users.
The divergence matters because transaction counts alone do not measure commercial adoption. Automated transactions, repeated interactions and other high-frequency activities can increase network throughput without producing equivalent growth in users, liquidity or revenue.
Wallet providers must also maintain security infrastructure, software integrations and customer support. Weakening demand can make those costs harder to justify, particularly for smaller projects.
Nevertheless, the closures do not establish that Sui’s underlying protocol is economically unsustainable, nor has Suiet publicly identified declining network activity as the reason for its decision.
Investor Takeaway
Sui’s growing transaction volume contrasts with declining user activity and DeFi liquidity. For investors, the more meaningful indicators are whether transaction growth generates sustainable fees, attracts committed capital and supports commercially viable applications.
How Have Sui’s Network Outages Affected Reliability?
Sui’s ecosystem difficulties have also coincided with repeated technical disruptions.
The blockchain experienced four mainnet outages during 2026, including a roughly six-hour interruption in January and three separate halts on May 28 and 29.
The May incidents interrupted transaction processing for approximately 16 hours combined. In its May 31 technical review, the Sui Foundation attributed the first two failures to bugs involving transaction gas calculations following the network’s version 1.72 upgrade.
A third outage occurred when validator restarts exposed a separate bug involving the preservation of randomness-related state.
The disruptions followed earlier reliability concerns, including the repeated network stalls covered by FinanceFeeds in May.
The Sui Foundation said the identified bugs had been addressed and that no user funds were at risk during the May outages. It also reported that previously committed transactions were not reversed when the network resumed operations.
Although the technical problems are distinct from the economic pressures facing wallet providers, repeated downtime creates additional operational uncertainty for developers, exchanges and DeFi users.
What Does the Decline Mean for Sui Investors?
Sui’s near-term challenge is whether its remaining applications can retain liquidity and users while maintaining dependable infrastructure.
DefiLlama data for November 11 placed DeFi TVL at roughly $414 million, while the network’s stablecoin market capitalization stood near $540 million. These represent different measures: TVL tracks assets deposited in DeFi protocols, whereas stablecoin capitalization measures the supply of stablecoins on the blockchain.
The ecosystem has previously faced significant security challenges, including the May 2025 Cetus Protocol exploit involving more than $220 million.
However, the latest wallet closures should not automatically be attributed to that incident or to the network’s subsequent outages. The available announcements establish separate operational decisions rather than a common cause.
Investors assessing Sui’s recovery will need to monitor sustained changes in active users, DeFi deposits, transaction fees and the availability of wallet infrastructure, rather than relying exclusively on headline transaction counts.
Investor Takeaway
The principal concern for Sui is the gap between network throughput and economically meaningful adoption. Recovering liquidity, retaining developers and preventing further service withdrawals would provide stronger evidence of ecosystem stabilization than transaction growth alone.
