Volo Suffers Attack, Loses Approximately $3.5 Million

On April 22, Volo— a liquidity mining platform within the Sui ecosystem— suffered a security breach, resulting in the theft of roughly $3.5 million in assets (including WBTC, XAUm, and USDC) from three specific vaults. Following the incident, the team promptly notified the Sui Foundation and ecosystem partners, and froze all vaults to prevent further losses. The breach only impacted three vaults; the remaining vaults do not share the same attack vector, and approximately $28 million in total value locked (TVL) assets remain secure. The team will cover the losses from the incident, will not pass them on to users, and plans to release a comprehensive post-incident report and remediation plan once the investigation concludes.
