Repay Borrow

The repay function transfers an asset into the protocol, reducing the user's borrow balance.

FBep20

function repayBorrow(uint repayAmount) returns (uint)

• msg.sender: The account which borrowed the asset, and shall repay the borrow.

• borrowAmount: The amount of the underlying borrowed asset to be repaid. A value of -1 (i.e. 2256 - 1) can be used to repay the full amount.

• RETURN: 0 on success, otherwise an Error Code.

Before repaying an asset, users must first approve the fToken to access their token balance.

FBnb
