Write an Ethereum smart contract

README.md

• Install Truffle

    npm install -g truffle

• Install Ganache

To install ganache globally as cli tool:

    npm install ganache --global

or install Ganache UI https://trufflesuite.com/ganache/

• Creating a Truffle project

    truffle init new_project

• Pick a contract name (for example Test)

    truffle create contract Test

• To run test in Truffle

    truffle test

• Compile the contracts

    truffle compile

Deploying the contract

• To deploy our contract in a testing environment, we use ganache cli tool (or use Ganache UI)

    ganache

It will start a RPC server. After running ganache it will provide you and endpoint to connect with (for example http://127.0.0.1:8545)

• To connect to this endpoint, modify the truffle-config.js

    networks: {
        ganacheLocal: {
            host: "127.0.0.1",
            port: 8545,
            network_id: "*"
        }

• Deploy contract

    truffle deploy --network ganacheLocal
