# Supply

Supplies the user's Ethereum asset to the Aquarius Loan.

* `asset` (string) A string of the asset to supply.
* `amount` (number | string | BigNumber) A string, number, or BigNumber object of the amount of an asset to supply. 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.
* `noApprove` (boolean) Explicitly prevent this method from attempting an ERC-20 `approve` transaction prior to sending the `mint` 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 `mint` transactions.
* `RETURN` (object) Returns an Ethers.js transaction object of the supply transaction.

```
const aquarius = new Aquarius(window.ethereum);

// Ethers.js overrides are an optional 3rd parameter for `supply`
// const trxOptions = { gasLimit: 250000, mantissa: false };

(async function() {

  console.log('Supplying ETH to the Aquarius Loan...');
  const trx = await aquarius.supply(Aquarius.ETH, 1);
  console.log('Ethers.js transaction object', trx);

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