Dockerized Ethereum Private Testing Environment Compatible with MetaMask and Remix

Reading Time: 2 minutes

The purpose of this configuration is to generate a Docker environment of 2 nodes connected together running on Geth and monitor them using Ethstat (at localhost:3000). Then we can use MetaMask as well as Remix to connect to the first node (localhost:8545) to send simple transtractions, like sending Ether, or complex transactions like the creation or call of a smart contract.

Using the CardContact SmartCard USB HSM in an Ethereum PoA Chain
