Suiet Wallet Shuts Down Amid Sui Ecosystem Exodus

Suiet, a self-custodial wallet built for the Sui blockchain, is shutting down, according to Cointelegraph. The project said in a notice that it will stop updating and supporting its wallet, with API services set to run only through Nov. 14. The closure adds Suiet to a growing list of infrastructure providers withdrawing from the Sui network at a moment when the chain's core usage metrics are moving in opposite directions: transaction counts are climbing while user activity and deposited capital are shrinking.

Event: Another Wallet Exits Sui

Suiet's shutdown immediately follows Sui-based hardware wallet project Suiball announcing its own closure on Nov. 10, Cointelegraph reported. The pattern extends further back: wallet provider Phantom ended support for Sui in September, and DeFi project Full Sail shut down following a security incident involving Switchboard that caused about $91,000 in losses, per Cointelegraph's reporting. Cointelegraph said it reached out to the Sui Foundation and Suiet for comment but had not received responses by publication.

The timing coincides with a measurable pullback in Sui's decentralized finance activity. Sui's total value locked stood at about $413 million on Wednesday, down more than 22% over the past month, according to DefiLlama data cited by Cointelegraph. Token Terminal data referenced in the report shows Sui averaged about 128,000 daily active users in October, down from 601,000 in November 2025 — a roughly 79% drop.

Implications: Economics, Not Protocol Failure

Kadan Stadelmann, former chief technology officer of Komodo Platform, told Cointelegraph that "Sui's problems seem to mostly be of an economic nature resulting from expensive engineering costs and low user volume rather than protocol failures," adding that "no flaw in the system's core design has been found." Stadelmann also framed the wallet exits as a broader cost calculation facing vendors who support multiple chains: "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." He added that "any individual failure of a multi-chain wallet is more a reflection of the risks rather than an indictment of any given protocol."

That framing matters because it separates two distinct possible explanations for the exodus — a technical defect in Sui itself versus a business-economics problem where the cost of maintaining integrations outweighs the user base supporting them. Stadelmann's comments point to the latter. Neither Suiet nor the Sui Foundation had responded to Cointelegraph by publication, so the wallet's own reasons have not been stated.

Notably, the activity picture is not uniformly negative. Transactions on Sui have actually increased, reaching 324 million in October, up from 101 million in November 2025, according to Token Terminal data cited in the report. However, more transactions do not necessarily mean more users, and wallet providers must still decide whether supporting the network is worth the cost, according to Stadelmann.

Network Reliability: Outage History in Focus

The wallet closures land against a backdrop of recorded network instability. Sui has experienced four network outages in 2026, resulting in around 22 hours of combined downtime, according to reports published by the Sui Foundation and cited by Cointelegraph. The network stopped processing transactions for about six hours in January, followed by three additional outages on May 28 and 29. Cointelegraph reported that the May disruptions were linked to software bugs, including problems introduced by a network update, according to the Sui Foundation's own account at the time.

Cointelegraph placed these figures in comparative context: Solana has not recorded a network-wide outage since February 2024, when it went offline for nearly five hours, while Aptos — which uses the same underlying smart contract programming language as Sui — last reported a mainnet outage in October 2023. Network outages carry real consequences for DeFi participants because they can prevent users from trading, transferring funds or managing open positions. The Sui Foundation said no user funds were at risk during the May disruptions, per Cointelegraph's reporting.

CoinHours analysis: reading the wallet exits against usage data

CoinHours analysis: The central puzzle is that Sui's transactions rose from 101 million in November 2025 to 324 million in October, while daily active users fell from 601,000 to about 128,000 over the same period, according to Token Terminal. Taken together, those figures mean more transactions are coming from far fewer users. The source does not break down who is generating that activity, so the numbers alone do not show whether demand is healthy.

The TVL figure is a separate signal. Sui's DeFi total value locked fell more than 22% in a month to about $413 million, per DefiLlama, and Cointelegraph does not attribute that decline to a single cause. The outage record adds another factor wallet vendors may weigh: four outages and about 22 hours of combined downtime in 2026, against no network-wide Solana outage since February 2024 and no Aptos mainnet outage since October 2023.

What to Watch

The near-term marker is Nov. 14, when Suiet's API services are scheduled to stop entirely per the company's notice. Beyond that date, the more consequential signals will be whether Sui's TVL and daily active user figures stabilize or continue their current trajectories, and whether additional wallet or infrastructure providers follow Suiet, Suiball, Phantom and Full Sail out of the ecosystem. A response from the Sui Foundation, which had not replied to Cointelegraph's request for comment by publication, would also clarify how it views the closures.
