Thanks for your answer! Unfortunately, I've already tested that case and I still get Failure event even though. I'll show you transactions with that kind of case: 1/ where I set the currentAmount variable to 0,8 USDT (800000 wei) -5e62243e46c5f8d641a8733b9829dbdd8cab10b15e6a7ff7322e88a05edcf36a 2/ where I try to borrow 0,672 USDT (by formula it is like 0,8 * 84%) 2489786df7cbbcf5d30fa6637f28e305f71f6cd140cd2e20ce243a2e7df1ead1 I was thinking about maybe smth wrong with decimals or with entering to Market transaction (make USDD token as collateral).. but I have not found any issues except "staked event" that does not appear in mine transaction d20e9f5b55c5d71471e2b00f8380491372904766d1623ec11a69f3b03a39ddc5)
