CrowdFunding

🧪 An open-source, up-to-date toolkit for building decentralized applications (dapps) on Starknet blockchain. It’s designed to make it easier for developers to create and deploy smart contracts and build user interfaces that interact with those contracts.

⚙️ Built using NextJS, Starknet.js, Scarb, Starknet-React, Starknet Foundry and Typescript.

  • ✅ Contract Fast Reload: Your frontend auto-adapts to your smart contracts as you deploy them.
  • 🪝 Custom hooks: Collection of React hooks wrapper around starknet-react to simplify interactions with smart contracts with typescript autocompletion.
  • 🧱 Components: Collection of common web3 components to quickly build your frontend.
  • 🔥 Burner Wallet & Prefunded Account: Quickly test your application with a burner wallet and prefunded accounts.
  • 🔐 Integration with Wallet Providers: Connect to different wallet providers and interact with Starknet network.

Requirements

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

Starknet-devnet version

To ensure the proper functioning of scaffold-stark, your local starknet-devnet version must be 0.2.0. To accomplish this, first check your local starknet-devnet version:

starknet-devnet --version
 

If your local starknet-devnet version is not 0.2.0, you need to install it.

Scarb version

To ensure the proper functioning of scaffold-stark, your local Scarb version must be 2.8.3. To accomplish this, first check your local Scarb version:

scarb --version
 

If your local Scarb version is not 2.8.3, you need to install it.

Starknet Foundry version

To ensure the proper functioning of the tests on scaffold-stark, your Starknet Foundry version must be 0.31.0. To accomplish this, first check your Starknet Foundry version:

snforge --version
 

If your Starknet Foundry version is not 0.31.0, you need to install it.

  • Install Starknet Foundry 0.31.0 via asdf (instructions).

Compatible versions

  • Starknet-devnet – v0.2.0
  • Scarb – v2.8.3
  • Snforge – v0.31.0
  • Cairo – v2.8.2
  • Rpc – v0.7.1

Quickstart with Starknet-Devnet

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

  1. Clone this repo and install dependencies
git clone https://github.com/Scaffold-Stark/scaffold-stark-2.git
cd scaffold-stark-2
yarn install
 
  1. Run a local network in the first terminal.
yarn chain
 

To run a fork : yarn chain --fork-network <URL> [--fork-block <BLOCK_NUMBER>]

This command starts a local Starknet network using Devnet. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in scaffold.config.ts for your nextjs app.

  1. On a second terminal, deploy the sample contract:
yarn deploy
 

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

By default Scaffold-Stark takes the first prefunded account from starknet-devnet as a deployer address,

  1. 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 Debug Contracts page. You can tweak the app config in packages/nextjs/scaffold.config.ts.

  1. Check your environment variables. We have a yarn postinstall script that helps to fill in your environment variables. If the environment variable does not exist, you can fill them it manually to get the app running!

What’s next

  • Edit your smart contract YourContract.cairo in packages/snfoundry/contracts/src
  • Edit your frontend homepage at packages/nextjs/app/page.tsx. For guidance on routing and configuring pages/layouts checkout the Next.js documentation.
  • Edit your deployment scripts in packages/snfoundry/script-ts/deploy.ts
  • Edit your smart contract tests in packages/snfoundry/contracts/src/test. To run tests use yarn test
  • You can write unit tests for your Next.js app! Run them with one the following scripts below.
    • yarn test:nextjs to run regular tests with watch mode
    • yarn test:nextjs run to run regular tests without watch mode
    • yarn test:nextjs run --coverage to run regular tests without watch mode with coverage

Conclusion

Scaffold-Stark is a powerful open-source toolkit that simplifies the development of decentralized applications (dApps) on the Starknet blockchain. It offers seamless integration with tools like Next.js, Starknet.js, and TypeScript, enabling easy smart contract deployment, fast front-end updates, and wallet provider connections. With a user-friendly setup and comprehensive resources, it streamlines the development process for creating robust dApps on Starknet.
