Full Sail Becomes 2026's Latest Protocol to Close After a Hack

Full Sail, a decentralized exchange, is winding down on Sui (SUI) after an attacker drained roughly $91,000 from three of its vaults on August 29.  The closure makes the DeFi protocol the latest 2026 casualty of a security failure rather than weak demand.

Our immediate priority is returning what affected users lost and completing an orderly wind down.— Full Sail ⛵ (@FullSailFi) September 1, 2026 Full Sail Winds Down After $91,000 Exploit Full Sail said the attacker exploited Switchboard production code that governs who can sign oracle price updates.

The attacker then added a key they controlled to a live oracle. Once the network accepted that key, false prices appeared valid. The attacker pushed prices to roughly 100 times below market and deposited into the affected vaults.
