🏗 Scaffold-ETH 2 powered smart contract portfolio

This repository contains all the implementation contracts of various use cases that I have built or experimented with. Navigate to the different branches to check the contract implementation and play with the contracts using Scaffold Eth UI

Note: Few of the contracts implemented here are only for learning purposes and might not be production ready. For those contracts, all the security best practices may or may not be followed due to time constraints.

(In progress - Many smart contracts are yet to be added soon)

Requirements to play with the contracts

Before you begin, you need to install the following tools:

• Node (v18 LTS)
• Yarn (v1 or v2+)
• Git

Quickstart

To get started with Scaffold-ETH 2, follow the steps below:

1. Clone this repo & install dependencies

git clone https://github.com/scaffold-eth/scaffold-eth-2.git
cd scaffold-eth-2
yarn install

2. Run a local network in the first terminal:

yarn chain

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in hardhat.config.ts.

3. On a second terminal, deploy the test contract:

yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/hardhat/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/hardhat/deploy to deploy the contract to the network. You can also customize the deploy script.

4. On a third terminal, start your NextJS app:

yarn start

Visit your app on: http://localhost:3000. You can interact with your smart contract using the contract component or the example ui in the frontend. You can tweak the app config in packages/nextjs/scaffold.config.ts.

Run smart contract test with yarn hardhat:test

• Edit your smart contract YourContract.sol in packages/hardhat/contracts
• Edit your frontend in packages/nextjs/pages
• Edit your deployment scripts in packages/hardhat/deploy
