dApp Starter Kit

Welcome!

This is a starter kit for building decentralized applications (dApps) using Solidity smart contracts and React.js frontend.

It provides a basic setup for building, testing, and deploying your dApp.

The starter kit includes a sample smart contract written in Solidity, a React.js frontend, and a Hardhat configuration for deploying to the Ethereum test networks (The sample contract is deployed in mumbai testnet).

It also includes scripts for compiling, deploying, and testing your dApp.

Whether you're a beginner or an experienced developer, this starter kit provides a solid foundation for building your next dApp. Get started quickly with our easy-to-use setup, or customize it to fit your specific needs.

Happy coding!

Getting started:

There are 2 branches:

1. multi-wallet-support
2. metamask-only

multi-wallet-support : recommended when building large scalable dApps. Supports a number of wallets from coinbase, trust wallet, walletconnect, metamask e.t.c

metamask-only: recommended when doing smaller projects, only supports Metamask wallet

Installation:

Clone the repository:

git clone https://github.com/Stephen-Kimoi/dApp-starter-kit.git

Depending on the type of project you are doing, checkout to the branch you'll be using

git checkout metamask-only - for smaller projects

git checkout multi-wallet-support - for large scalable dApps

npm install

cd frontend & npm install

Once dependencies are installed run the following command:

cp .env.example .env;

Now add your alchemy api key i.e ALCHEMY_API_KEY and private key i.e PRIVATE_KEY

You can get your alchemy api key over here You can see how to get your private key over here

Finally run:

npm run dev

This is the UI you'l see:

Sample contract is found in contracts/Counter.sol

The deploy script is found in scripts/deploy.js

NB: You do not need to manualy copy paste the contract ABI and address when you run the deploy script, the saveFrontendFiles function inside the deploy.js script automatically creates a folder named contracts inside the frontend/src directory which contains:

├── contracts/ 
    ├── contract-address.json - contains contract address 
    ├── Contract.json - contains contract ABI

The command for running the deploy script is: npm run deployTestnet (check out package.json in the main directory)

This command deploys the contract to mumbai testnet

If you want to test the smart contract locally without having to deploy it:

1. Run npx hardhat node for starting the hardhat node network.
2. Run npm run deployLocal deploys contract to local hardhat network that you've just started.

Site description

When you run npm run dev this is the site that you'll see:

Click on the connect wallet button and this pop-up will appear:

For metamask-only branch:

For mutli wallet branch:

Once you connet your wallet succesfully this is what you'll see (For both branches):

You can now start editing it to suit the project you're doing

NB: The contract is deployed in mumbai testnet, therefore ensure you've switched to mumbai testnet and have some mumbai matic to prevent any errors.
