Local Node Project

This project use Hardhat to run local Ethereum node.

Docker setup

Requirements

• Docker
• Git

If you run it before, please remove the old container with docker rm hardhat

Setup

1. Clone this repository

2. Run

docker build -t local-node . &&  docker run -e MAINNET_URL={MAINNET_URL} -p {PORT}:8545 -i -t --name hardhat --rm local-node`

For MAINNET_URL, you can use Infura, Alchemy, or Tenderly. If you want to fork a network other than Ethereum mainnet, simply provide a RPC endpoint to the desired chain. For CHAIN_ID, use your preferred number. The default is 2137, which is our legacy number for the Ethereum mainnet fork. If you want to fork a different network, use a different CHAIN_ID. For the PORT, use the port you want for the local node. We use 8545 in our other repositories. However, if you need to have multiple RPC nodes for multiple networks, use different ports.

Local setup

Please add .env file to the root directory with the following content:

BLOCK_NUMBER=1
MAINNET_URL={YOUR_MAINNET_URL}
CHAIN_ID={YOUR_CHAIN_ID}

MAINNET_URL and CHAIN_ID are explained earlier.

Then run the following commands:

yarn 
yarn run start
