The withdraw method is used to withdraw collateral that is not currently supporting an open borrow. Withdraw is also used to borrow the base asset from the protocol if the account has supplied sufficient collateral. It can also be called from an allowed manager address.
Lenen Protocol implements a minimum borrow position size which can be found as baseBorrowMin in the protocol configuration. A withdraw transaction to borrow that results in the account’s borrow size being less than the baseBorrowMin will revert.
