On March 31, 2022, the protocol's deployment on the Fuse Network was exploited via a reentrancy vulnerability in ERC677 token logic, resulting in approximately $4.67 million in stolen assets. The attacker used Tornado Cash to obscure initial funding, laundered proceeds through Ethereum and BNB Chain wallets, and was never publicly identified; a partial compensation plan was offered but fell materially short of full victim restitution.","timeline":[{"date":"2021-05-26","event":"Fuse Lending Network powered by Ola Finance goes live on Fuse Network, initially supporting FUSE, WETH, WBTC, and USDC.","source":""},{"date":"2022-03-31","event":"Ola Finance's Fuse Network deployment exploited via ERC677 reentrancy vulnerability.
