Late last week, a FODL user discovered a bug in the Polygon & BSC L2 platform that has since been fixed. The bug occured in the opening and closing of positions, where the slippage setting input by the user did not save into parameter settings. ALL FUNDS ARE SAFU.
The bug resulted in the ability for MEV arbitrages in the looping transactions when opening and closing positions. As stated, this bug has been fixed as of late UTC April 1, 2022, and position openings on Polygon & BSC are no longer affected.
The FODL user and community member who brought discovered this bug was arbitraged for approximately 13 ETH (9 ETH on the entry transaction and 4 ETH on the exit transaction).
