# Borrow

Borrows an Ethereum asset from the Aquarius Loan for the user. The user's address must first have supplied collateral and entered a corresponding market.

* `asset` (string) A string of the asset to borrow (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.
* `[options]` (CallOptions) Call options and Ethers.js overrides for the transaction.
* `RETURN` (object) Returns an Ethers.js transaction object of the borrow transaction.
