Usage

The below is a simple example of lending an ERC721, note that the amount is ignored, you will always lend 1 unit of ERC721 token.

If you are having any issues with the below code, go here and ensure your dependencies for ethersproject are the same as ours (in package.json).

You might be wondering what 'AZRAEL' refers to in the below import. If so, go to our docs here. Azrael, Sylvester and Whoopi are our naming conventions to refer to different versions of our contracts.

import { JsonRpcProvider } from '@ethersproject/providers';
import { Wallet } from '@ethersproject/wallet';
import { DEPLOYMENT_AZRAEL_ETHEREUM_MAINNET_V0, PaymentToken, getRenftContract } from '@renft/sdk';

// const walletMnemonic = Wallet.fromMnemonic(`<your mnemonic>`);
const provider = new JsonRpcProvider('<your provider uri>');
const privKey = '<privateKey>';
let wallet = new Wallet(privKey);
wallet = wallet.connect(provider);

const main = async () => {
  const renft = getRenftContract({
    deployment: DEPLOYMENT_AZRAEL_ETHEREUM_MAINNET_V0,
    signer: wallet,
  });

  const nftAddress = ['0xCDf60B46Fa88e74DE7e1e613325E386BFe8609ad'];
  const tokenId = ['3'];
  const lendAmount = [1]; // for ERC721, this is ignored
  const maxRentDuration = [1];  // in days (can be returned earlier)
  const dailyRentPrice = [1.1]; // this will automatically scale
  const nftPrice = [2.2]; // this will automatically scale
  const paymentToken = [PaymentToken.WETH];

  const txn = await renft.lend(
    nftAddress,
    tokenId,
    lendAmount,
    maxRentDuration,
    dailyRentPrice,
    nftPrice,
    paymentToken
  );

  const receipt = await txn.wait();
  return receipt;
};

main()
  .then(receipt => {
    console.log(receipt);
  })
  .catch(e => {
    console.warn(e);
  });
