Self-custodial wallet Suiet is ending updates and technical support as of November 14, 2026. On that date, all official wallet application programming interface (API) access will be discontinued. The decision extends a growing list of infrastructure providers exiting the Sui ecosystem.
Prior to Suiet’s shutdown announcement, hardware wallet project Suiball shuttered operations on November 10, 2026. Wallet provider Phantom also withdrew its support for the Sui network in September 2026. In the application sector, decentralized finance protocol Full Sail halted operations following a hack on the Switchboard oracle that resulted in a $91,000 loss.
Why Are Developers Choosing to Exit?
Tech observers note that the high maintenance costs of custom network architectures are weighing heavily on multi-chain wallet developers struggling to monetize their user bases. This comes despite a recent surge in network activity: Sui’s monthly transaction volume climbed from 101 million to 324 million transactions over the same period.
Sui’s average daily active users in October 2026 fell to around 128,000, according to Token Terminal data. This represents a 79% decline from 601,000 daily users in November 2025. The drop in user engagement coincided with capital contraction. Data from DefiLlama shows that Total Value Locked (TVL) across Sui’s DeFi ecosystem dropped by more than 22% over the past month to around $413 million by mid-November 2026.
Four Network Outages on Record
System reliability has also come under scrutiny throughout 2026. The Sui network recorded four total outages with cumulative downtime reaching roughly 22 hours. These included a 6-hour outage in January alongside three consecutive incidents on May 28 and 29, 2026, triggered by a software update bug.
By comparison, rival blockchain Solana has not recorded a system outage since February 2024. Meanwhile, Aptos last experienced a mainnet outage in October 2023. These contrasting operational track records serve as a key consideration for developers assessing the efficiency of their technical resource allocation.
For asset holders relying on Suiet, the API service termination on November 14, 2026, requires transferring private keys and balances to another wallet before system access is cut off. While closing a self-custodial wallet does not erase on-chain balances, users will lose their primary interface for directly managing their crypto assets.
