Sui DeFi protocol Full Sail to wind down after Switchboard incident

Full Sail, a decentralized finance (DeFi) protocol on the Sui blockchain, plans to shut down after a security incident involving oracle provider Switchboard resulted in user losses.

Full Sail took to X on Tuesday to announce that the protocol is winding down, immediately disabling new deposits and liquidity provider (LP) reward claims. Regular pools will move to withdrawal-only mode after final security checks, with compensating users the protocol’s top priority, Full Sail said.

The decision follows a security incident last week that affected Full Sail’s automated vaults following a suspected compromise of Switchboard’s oracle infrastructure.

Full Sail first disclosed the incident on Saturday, saying it had confirmed a loss of funds and paused deposits and withdrawals while it investigated. Switchboard said in an X post on Saturday that it was investigating a potential compromise of its Move-based implementations and had halted its network on Aptos, Sui, IOTA and Movement.

Full Sail later said an attacker removed about $91,000 from three of its vaults. Virtue, a stablecoin lending protocol based on IOTA (IOTA), separately reported about $455,000 in losses and said the backing of its VUSD stablecoin had been impaired.
