Suiet Ends Support, API Services to Run Through Mid-November
Suiet, a self-custodial wallet purpose-built for the Sui blockchain, has announced it will discontinue all updates and ongoing support for its product. The wallet's API services will remain operational until November 14 before being fully terminated. The decision places Suiet among a growing list of projects that have exited or withdrawn from the Sui ecosystem in recent weeks, underscoring mounting pressure on the network's surrounding tooling and developer landscape.
The timing of the shutdown coincides with a pronounced contraction in decentralized finance activity on Sui. According to data tracked by DefiLlama, the network's total value locked (TVL) stood at roughly $413 million as of Wednesday, representing a decline of more than 22% over the preceding 30-day period. User engagement metrics tell a steeper story: Token Terminal data shows Sui averaged approximately 128,000 daily active users in October, a figure that sits well below the 601,000 recorded in November 2025 — an approximate 79% drop in active participation within about a year.
A Pattern of Closures and Support Withdrawals
Suiet's exit does not stand alone. Earlier on November 10, Suiball, a hardware wallet project built around the Sui chain, announced its own closure. In September, major multi-chain wallet provider Phantom dropped support for Sui entirely. DeFi protocol Full Sail also ceased operations following a security incident tied to the Switchboard oracle that resulted in approximately $91,000 in losses.
Taken together, these departures have prompted observers to question whether the cost structure of maintaining services on Sui remains sustainable for smaller teams. Kadan Stadelmann, former chief technology officer at Komodo Platform, described the situation to Cointelegraph as fundamentally an economic challenge rather than a technical one. He noted that expensive engineering requirements combined with relatively low user volumes are the primary drivers, while emphasizing that no structural flaw in the protocol's core architecture has been identified.
The publication reached out to both the Sui Foundation and Suiet for comment but had not received a reply by the time of writing.
Transaction Volume Rises Even as Active Users Fall
A counterpoint to the user decline is a sharp increase in raw transaction counts. Token Terminal data indicates that Sui processed 324 million transactions in October, up substantially from 101 million in November 2025. However, Stadelmann cautioned that a higher transaction count does not automatically translate into a larger or more engaged user base. Wallet providers and other service vendors still face the practical question of whether supporting the network justifies the ongoing resource investment, particularly when they can redirect their efforts toward chains with lower capital requirements.
He also highlighted the security considerations inherent in multi-chain wallet design, pointing out that each additional chain expands the potential attack surface. In his view, an individual failure in a multi-chain wallet reflects the broader risk profile of that architecture rather than indicting any single protocol. He added that vendors are free to migrate their operations to less capital-intensive chains, a flexibility that Sui's cost structure may not always accommodate.
Network Reliability and Competitive Context
Sui has also dealt with a series of infrastructure disruptions. According to reports published by the Sui Foundation, the network experienced four outages in 2026, amounting to roughly 22 hours of combined downtime. The first incident occurred in January and lasted approximately six hours, during which the chain halted transaction processing. Three additional outages followed on May 28 and 29, which the Foundation attributed to software bugs, including issues introduced by a network update at the time.
The Sui Foundation stated that no user funds were placed at risk during the May disruptions, though the outages nonetheless prevented DeFi participants from trading, transferring assets, or managing open positions. For context, rival high-throughput chain Solana has not logged a network-wide outage since February 2024, when it went offline for nearly five hours. Aptos, which shares Sui's underlying smart contract programming language, last recorded a mainnet outage in October 2023.
The convergence of declining active users, rising transaction costs for service providers, recurring outages, and a cascade of project closures paints a picture of an ecosystem under significant economic and operational strain — even as its underlying protocol design has not been called into question by industry analysts.
