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

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.
