Supply

Supplies the user's Ethereum asset to the Belugas Protocol.

  • 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 belugas = new Belugas(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 Belugas Loan...');
  const trx = await belugas.supply(Belugas.ETH, 1);
  console.log('Ethers.js transaction object', trx);

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