Voltage Finance
Summary
Voltage Finance (formerly FuseFi) is a decentralized finance protocol operating on the Fuse Network, offering token swapping, lending, liquidity farming, and cross-chain bridging via an automated market maker. The protocol has been the subject of two confirmed security exploits: a March 2022 reentrancy attack that drained approximately $4.67 million from its lending pools via a third-party partner (Ola Finance), and a March 2025 insider-related exploit of its Simple Staking pools resulting in approximately $322,000 in losses. No funds were recovered in either incident as of the time of this investigation.
