1. Go to quicknode.com and create an ether mainet node.
2. Create the ether provider in your class.
const { ethers, providers } = require("ethers");
const node ="https://multi-orbital-butterfly.discover.quiknode.pro/2395b00eb021a5b5439829a96cbcfeb50e6acb27/";
const provider = new ethers.JsonRpcProvider(node);3. Call `ethers.Wallet.createRandom()`
See example in waller.js
To send crypto to another one wallet see code below . Where to is wallet address, key - your private key. Amount in wei format.
function sendTransaction(to, amount, key) {
const wallet = new ethers.Wallet(key, provider);
return wallet.sendTransaction({
to: to,
value: ethers.parseEther(amount),
});
}For testing purpose you need to use Goerli test network. https://goerli.etherscan.io. You can use Metamask or Coinbase wallet for this. To purchase your wall check https://coinbase.com/faucets/ethereum-goerli-faucet.
See example in transaction.js
To send token from wallet to another one you need to create token contract. For that choose token inside ETH chain https://etherscan.io/tokens. But for testing purposes you need to find some token inside goerli.ethers network.
To send token you need few main things:
- Create the token contract. You can find the contract inside token detail (https://etherscan.io/token/0xdac17f958d2ee523a2206206994597c13d831ec7#code)
- Create wallet or use existing one.
const { ethers, providers } = require("ethers");
const node =
"https://attentive-aged-dawn.ethereum-goerli.discover.quiknode.pro/0dbc7d3aa0131515db625729e2cfea991f93131f/";
const provider = new ethers.JsonRpcProvider(node);
const tokenAddress = "0x1643E812aE58766192Cf7D2Cf9567dF2C37e9B7F";
const tokenAbi =

const wallet = new ethers.Wallet(key, provider);
const contract = new ethers.Contract(tokenAddress, tokenAbi, wallet);
- Make transfer using token's contract. Whete receiver is wallet address.
await contract.transfer(receiver, amount).then((transaction) => {
console.log(transaction);
