Examples

Below is a straightforward example of using createBatch to lock tokens into vouchers with Ether.js

const ethers = require('ethers');

const provider = new ethers.providers.JsonRpcProvider('https://avalanche.public-rpc.com');
const signer = new ethers.Wallet("", provider);

const VOUCHER_CONTRACT = '0xbB740E17f3c177172CaAcCef2F472DB41b9b1d19';
const LOCK_TOKEN = "";
