Summary

Sirio Finance is a DeFAI lending and borrowing protocol built on the Hedera blockchain that launched on January 27, 2025 and suffered a flashloan exploit on February 1, 2025, resulting in an estimated $2–3 million in stolen funds. The exploit occurred within five days of mainnet launch, with post-incident analysis indicating the vulnerability was introduced when the team followed an audit directive from QuillAudits to remove a reentrancy guard from the protocol's smart contracts. The protocol's TVL collapsed to near zero following the hack, and no confirmed recovery of stolen funds or full user compensation has been publicly documented.
