I'm using Hardhat with the waffle plugin to test my smart contract.

To get Signers (ether.js) I'm using :

await ethers.getSigners();

This return an array with 20 signers. If I call again, I get the same 20 signers, but how do I get a new one ?

Using ethers.Wallet.createRandom() from François Guyot this is how I managed to get many Signers for my tests.

ctx is your contract instance and addr1 is one of the Signer you got by calling await ethers.getSigners();

            for( let i=0; i < nb; i++){
                // Get a new wallet
                wallet = ethers.Wallet.createRandom();
                // add the provider from Hardhat
                wallet =  wallet.connect(ethers.provider);
                // send ETH to the new wallet so it can perform a tx
                await addr1.sendTransaction({to: wallet.address, value: ethers.utils.parseEther("1")});
                await ctx.connect(wallet).CallYouContract())

You could generate a bunch of random signers by doing this:

import { ethers } from 'ethers'

export const randomSigners = (amount: number): Signer[] => {
  const signers: Signer[] = []
  for (let i = 0; i < amount; i++) {
  return signers

    Thank you François for your help. To make it work with Hardhat and Waffle I had to add a provider but this helped me to go in the right direction. Commented Mar 10, 2022 at 15:51

If you're using hardhat, the default number of account (20) can be changed in the config:


networks: {
        hardhat: {
            accounts: {
                count: 60,
                // accountsBalance: 10000000000000000000000, // default value is 10000ETH in wei

The getSigners function will retrieve all the accounts.

More parameters for the accounts are defined in the hardhat documentation
