GSN Helpers ethers.js version

Problem

Recently I was in need to deploy my own GSN relayer on a custom network. I downloaded the official package @openzeppelin/gsn-helpers, after a few attempts I realised that setting up a custom GSN infrastructure is pain in the ass because of web3. I have rewritten the fragments of code responsible for setting up a relayer to ethers to make it as simple as possible and support custom deployments.

To start using simply install this package using yarn add https://github.com/marcellobardus/gsn-helpers-ethers.git

and then

import { startGSNInfrastructure } from "gsn-helpers-ethers";

const privKey = "0x...";
const ethereumNodeUrl = "http://localhost:8545";

const gsnRelayerUrl = "https://mydomain.com";
const relayerStakeEther = 1;
const relayerUnstakeDelaySecond = 604800; // 1 week
const relayerFundsEther = 5;
const relayerQuiet = true; // turns off relayer logs

const gsnRecipientContractAddress = "0x...";
const gsnRecipientFundsEther = 0.5;

startGsnInfrastructure(
  privKey,
  ethereumNodeUrl,
  {
    url: gsnRelayerUrl,
    stakeEther: relayerStakeEther,
    unstakeDelaySecond: relayerUnstakeDelaySecond,
    fundsEther: relayerFundsEther,
    quiet: relayerQuiet,
  },
  {
    address: gsnRecipientContractAddress,
    fundsEther: gsnRecipientFundsEther,
  }
);

Have fun.
