hardhat-deploy multi-chain

Problem Statement

The idea was to explore how to modify my existing tool : https://github.com/wighawag/hardhat-deploy/ to support multiple network deployment.My tool relies on hardhat which itself do not support multiple network deploymentI explored the idea a bit but did not have time to get something fully working.

Solution

It is made in typescript reusing the existing code at https://github.com/wighawag/hardhat-deployIt allow you to use one deploy script that perform transaction on multiple network and get access of the result.This has been tested with optimism and the deployment of a simple ERC20 and its gateway
