Suiet wallet to end API services after Nov. 14 as Sui DeFi TVL drops

Suiet, a browser-extension wallet built for the Sui blockchain, is closing: its team will stop all development and maintenance, and API services end after Nov. 14, 2026, according to Crypto Briefing. The wallet’s exit lands as Sui’s decentralized finance activity cools, with the chain’s DeFi total value locked down more than 22% over the past month.

Suiet is a self-custodial wallet, and its team is telling users to back up recovery phrases or private keys now so the credentials can be imported into a compatible wallet, Crypto Briefing reported. The Chrome extension is expected to be withdrawn shortly after the API services go dark, and because Suiet never offered a mobile app, there is no phone-based fallback. Cointelegraph reported the notice and said the API services would keep running through Nov. 14.

Key facts

• Suiet will stop developing and supporting its wallet, with API services ending after Nov. 14, 2026.
• Sui’s DeFi TVL stood at about $416.92 million on Nov. 11, 2026, down more than 22% from the prior month, per Crypto Briefing; Cointelegraph put the figure at about $413 million on Wednesday, citing DefiLlama.
• Phantom ended support for Sui on Sept. 24, 2026, and the Suiball hardware wallet project announced its own shutdown on Nov. 10, according to Cointelegraph.
• Sui averaged about 128,000 daily active users in October, down from 601,000 in November 2025, while transactions rose to 324 million from 101 million over the same comparison, Cointelegraph reported, citing Token Terminal.
• Scallop and Slush were named as alternative wallets, and the official Sui team has been guiding users on migration paths.

A pattern of departures

Suiet is not the first infrastructure provider to leave. Phantom, a widely used multichain wallet, dropped Sui support on Sept. 24, 2026. The Suiball hardware wallet project announced its closure on Nov. 10, 2026, citing heightened security concerns, per Cointelegraph. Cointelegraph also reported that the DeFi project Full Sail shut down after a security incident involving Switchboard that caused about $91,000 in losses.

Kadan Stadelmann, former chief technology officer of Komodo Platform, told Cointelegraph that Sui’s problems appear mostly economic, driven by costly engineering and low user volume rather than failures in the protocol itself, and that no flaw in the system’s core design had been found. He also said multichain wallets carry expansive attack surfaces and that Sui’s approach adds costs for vendors who can operate on less capital-intensive chains. Cointelegraph said it sought comment from the Sui Foundation and Suiet but had not received responses by publication.

Users’ immediate priority

Since a wallet never actually holds coins, Suiet users’ balances remain on the Sui chain. The practical task is to secure the recovery phrase or private key and import it elsewhere before Nov. 14. Crypto Briefing advised confirming that restored addresses in the new wallet match the old ones before deactivating the Suiet extension.

Shutdowns tend to draw opportunists. Users should treat unsolicited links, “migration tools,” or support messages that ask for a recovery phrase with suspicion, because no legitimate service needs a phrase sent to it. There are some offsets: the Sui team is engaging directly on migration, and alternatives like Scallop and Slush give stranded users somewhere to land.

Why it matters

Wallet support is the front door to a chain, and each departure narrows the routes users have for holding and moving assets. Sui’s fall in TVL suggests capital is leaving its lending, trading and yield protocols, or that asset prices have dropped, or both. Cointelegraph also noted that Sui has suffered four network outages in 2026 totaling about 22 hours of downtime, while transaction counts have climbed even as active users have fallen.

What to watch

The immediate marker is Nov. 14, 2026, when Suiet’s API services stop and the extension is expected to follow. Also watch whether the Sui Foundation responds to requests for comment and whether the pace of exits among wallet and DeFi providers slows.
