Suiet to Cease Sui Wallet Support as Ecosystem Withdrawals Mount

Self-custodial cryptocurrency wallet Suiet announced it will halt updates and customer support, scheduling the termination of its API services after Nov. 14 ¹. The shutdown marks another infrastructure departure from the Sui blockchain following wallet provider Phantom's exit in September and hardware wallet project Suiball's closure announcement on Nov. 10 ¹.

The closure coincides with declining on-chain metrics across the layer-1 network ¹. Total value locked on Sui fell by more than 22% over the trailing month to roughly $413 million, based on DefiLlama data ¹. Meanwhile, monthly figures from Token Terminal show Sui averaged approximately 128,000 daily active users in October, representing a 79% decline from 601,000 in November 2025, even as monthly transactions increased to 324 million from 101 million over the same timeframe ¹.

Infrastructure Pressures and Outages

Sui-native decentralized finance protocol Full Sail also ceased operations following an exploit involving oracle provider Switchboard that generated roughly $91,000 in losses ¹. Commenting on the departures, former Komodo Platform chief technology officer Kadan Stadelmann noted that maintaining multi-chain wallet infrastructure on Sui creates economic overhead and expanded attack surfaces relative to lower-cost ecosystems, pointing to low user volume rather than core protocol defects ¹.

Operational stability has also faced scrutiny following four network disruptions in 2026 that generated roughly 22 cumulative hours of downtime, according to Sui Foundation documentation ¹. An initial six-hour halt occurred in January, followed by three software-related outages on May 28 and 29, though the foundation stated that user funds were never compromised ¹. At the time of writing, $SUI traded at $0.8136, down 1.0% over the preceding 24 hours.
