大量にウォレットアドレス用意するマン

index.js

const ethers = require("ethers");
const fs = require("fs");

const createCount = 150;
let createdAddress = [];

for (let i = 0; i < createCount; i++) {
  const wallet = new ethers.Wallet.createRandom();
  createdAddress.push(wallet.address);
}

console.log(createdAddress);

try {
  fs.writeFileSync("address.json", JSON.stringify(createdAddress));
  console.log("write end");
} catch (e) {
  console.log(e);
}

const createCount = 1000;

こうすると1000件作れます
