# Repay Borrow

Repays a borrowed Ethereum asset for the user or on behalf of another Ethereum address.

* `asset` (string) A string of the asset that was borrowed (must be a supported underlying asset).
* `amount` (number | string | BigNumber) A string, number, or BigNumber object of the amount of an asset to borrow. Use the `mantissa` boolean in the `options` parameter to indicate if this value is scaled up (so there are no decimals) or in its natural scale.
* `[borrower]` (string | null) The Ethereum address of the borrower to repay an open borrow for. Set this to `null` if the user is repaying their own borrow.
* `noApprove` (boolean) Explicitly prevent this method from attempting an ERC-20 `approve` transaction prior to sending the subsequent repayment transaction.
* `[options]` (CallOptions) Call options and Ethers.js overrides for the transaction. A passed `gasLimit` will be used in both the `approve` (if not supressed) and `repayBorrow` or `repayBorrowBehalf` transactions.
* `RETURN` (object) Returns an Ethers.js transaction object of the repayBorrow or repayBorrowBehalf transaction.
