In this project, I was able to deployed a contract to Goerli Blockchain using code. I used technologies like Solidity, Javascript, Ethers.js, Ganache, Prettier - Code formatter, Alchemy

Ethers Simple Storage

Getting Started

Requirements

• git
  • You'll know you did it right if you can run git --version and you see a response like git version x.x.x
• Nodejs
  • You'll know you've installed nodejs right if you can run:
    • node --version and get an ouput like: vx.x.x
• Yarn instead of npm
  • You'll know you've installed yarn right if you can run:
    • yarn --version and get an output like: x.x.x
    • You might need to install it with npm
• ganache
  • You'll know you did it right if you can run the application and see:
    
  • You can alternatively use ganache-cli or hardhat

Setup

Clone this repo

git clone https://github.com/DevSammy22/ethers-simple-storage-smart-contract-project.git
cd ethers-simple-storage-smart-contract-project

Then install dependencies

yarn

Usage

1. Run your ganache local chain, by hitting quickstart on your ganache application

Save the workspace. This way, next time you open ganache you can start the workspace you've created, otherwise you'll have to redo all the steps below.

2. Copy the RPC SERVER sting in your ganache CLI, and place it into your .env file.

.env Example:

RPC_URL=http://0.0.0.0:8545

3. Hit the key on one of the accounts, and copy the key you see and place it into your .env file, similar to what you see in .env.example.

.env Example:

PRIVATE_KEY=11ee3108a03081fe260ecdc106554d09d9d1209bcafd46942b10e02943effc4a

4. Compile your code

Run

yarn compile

You'll see files SimpleStorage_sol_SimpleStorage.abi and SimpleStorage_sol_SimpleStorage.bin be created.

5. Run your application

node deploy.js

For WSL users

1. Run

yarn add ganache

2. Change Server settings in Ganache

Settings > Server > Host Name

Change Host Name to vEthernet (WSL)

3. Run your application

node deploy.js

Deploying to a testnet

Make sure you have a metamask or other wallet, and export the private key.

IMPORTANT

USE A METAMASK THAT DOESNT HAVE ANY REAL FUNDS IN IT. Just in case you accidentally push your private key to a public place. I highly recommend you use a different metamask or wallet when developing.

1. Export your private key and place it in your .env file, as done above.

2. Go to Alchemy and create a new project on the testnet of choice (ie, Goerli)

3. Grab your URL associated with the testnet, and place it into your .env file.

4. Make sure you have testnet ETH in your account. You can get some here. You should get testnet ETH for the same testnet that you made a project in Alchemy (ie, Goerli)

5. Run

node deploy.js
