Fact Check
The claim is strongly supported. The official Volo source, x post 2046715584201511351, confirms a security incident affecting vaults and says Volo will absorb losses. Odaily's report, which explicitly cites that Volo post, provides the specific details in the claim: about $3.5 million lost, the assets WBTC/XAUm/USDC, notification to Sui Foundation and partners, a freeze/suspension of vaults, and that roughly $28 million in other TVL remained secure because the issue was isolated to three vaults. The Block Co's post independently corroborates the $3.5 million exploit and affected assets. I found no contradictory evidence in the gathered sources.
