fork Mainnet with ganache-cli

To fork off Mainnet, simply invoke the -f flag on ganache-cli. The -i flag indicates a network ID of 1. npx ganache-cli -f https://mainnet.infura.io/v3/{key} -i 1

This will spawn a Ganache instance at http://localhost:8545. This Infura API key is obtained publicly from https://infura.io.

NOTE:Unfortunately have to restart ganache-cli every 128 blocks (~30 minutes), otherwise you may be greeted with the following message from Infura:Returned error: project ID does not have access to archive state
