PAC Finance, a lending protocol on $Blast Network and an $Aave fork, experienced $26 million in 'unnecessary liquidations' on April 11 due to a sudden decrease in the liquidation threshold for user positions. The change was made without prior announcement or a timelock, leading to large liquidations. $AAVE's creator, Stani Kulechov, highlighted the issue, noting the fundamental problem with forking code is the lack of in-depth knowledge of the software and parameters. A single address profited about 244 $ETH from the event, which accounted for 93% of the liquidations. PAC Finance acknowledged the issue and is developing a plan to mitigate it, including setting up a governance contract/timelock and forum for future upgrades.
