# Borrow

Borrows an Ethereum asset from the Agile Protocol 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.

```
const agile = new Agile(window.ethereum);

(async function() {

  const usdtScaledUp = '32000000000000000000';
  const trxOptions = { mantissa: true };

  console.log('Borrowing 32 Usdt...');
  const trx = await agile.borrow(Agile.USDT, usdtScaledUp, trxOptions);

  console.log('Ethers.js transaction object', trx);

})().catch(console.error);
