The Sui ecosystem has faced another painful reminder of the fragility of DeFi infrastructure. The Full Sail protocol, operating on this network, has officially announced the winding down of its operations following an incident related to a vulnerability in the Switchboard oracle. As a result of the attack, the malicious actor withdrew approximately $91,000 from three of the project's vaults, which proved to be a fatal blow to its operational model.
Incident Details and Team Response
Immediately after detecting the breach, Full Sail's administration took emergency measures: new deposits and reward accruals were suspended. This is a standard protocol of action in the face of such threats, but in this case, it did not save the project from closure. The team stated that it would direct its own liquidity to cover user losses and, if necessary, compensate for the shortfall. The priority is the full return of assets to affected depositors.
It is worth emphasizing that the sum of $91,000 is not catastrophic for a major player, but for a mid-sized DeFi protocol, it can prove critical. The complete shutdown after a relatively small hack suggests that Full Sail likely lacked a sufficient safety margin or insurance fund. This is a signal for the entire industry: even secondary components, such as oracles, can become points of failure.
Analytical Perspective
In my practice, such cases are not uncommon. Oracles remain one of the most vulnerable links in the DeFi chain because they rely on external data sources. The attack on Switchboard was likely related to the manipulation of price feeds, which allowed the hacker to deceive the logic of the vaults. Full Sail's complete exit from the market is not just the loss of a single project, but a wake-up call for developers on Sui, who should reconsider their security strategies before launching new products.
