Volo said it identified a security issue on the Sui network that impacted its BTCFi and LST protocol, leading to the theft of about $3.5 million in assets from three Vaults. The stolen funds included WBTC, XAUm and USDC. The team has alerted the Sui Foundation and other ecosystem partners and has frozen all Vaults. Volo added that only the three Vaults were affected and that the remaining $28 million in total value locked (TVL) is secure. Volo said it will make users whole and will publish a post-incident report along with a remediation plan.

Odaily Planet Daily reported that on-chain analyst Aunt Ai said the Venus attacker sent 2,301 ETH—about $5.32 million—to address 0xa21…23A7f roughly 11 hours ago, then routed the funds in batches into Tornado Cash in an apparent laundering attempt. Around $17.45 million in ETH remains on-chain.

USDT supply on Tron has climbed to a new all-time high of about $86.7 billion, according to CryptoQuant. The milestone comes as Tether's new wallet product does not support the network.

Volo, a liquid staking platform in the Sui ecosystem, said on April 22 that it suffered a security breach that resulted in the theft of about $3.5 million from three Vaults. The stolen assets included WBTC, XAUm and USDC. The team said it immediately alerted the Sui Foundation and ecosystem partners and froze all Vaults to prevent additional losses. Volo added that the vulnerability was limited to the three affected Vaults, with no other Vaults exposed to the same attack vector. Roughly $28 million in TVL remains secure. Volo said it will cover the losses and will not pass costs on to users. A full incident report and remediation plan will be released once the investigation is completed.

Odaily Planet Daily cited on-chain analyst Yujin as saying the KelpDAO attacker began laundering funds yesterday afternoon and has likely moved 34,500 ETH (about $80 million) so far. The bulk of the ETH was swapped cross-chain into BTC via THORChain, generating sizable "toll" fees for the protocol. Over the past 24 hours, THORChain trading volume jumped to $360 million, versus a prior daily average of around $20 million. Fee revenue on the platform also climbed to $420,000 in the same period, up from roughly $5,000 per day previously.
