Lisk

Scaffold-Lisk is a fork of Scaffold-OP with minimal differences, providing additional dApp examples, native support for Superchain testnets, and more low-level instructions. We highly recommend the Scaffold-ETH2 docs as the primary guideline.

🧪 An open-source, up-to-date toolkit for building decentralized applications (dapps) on the Ethereum 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, RainbowKit, Hardhat, Wagmi, Viem, and Typescript.

  • Contract Hot Reload: Your frontend auto-adapts to your smart contract as you edit it.
  • 🪝 Custom hooks: Collection of React hooks wrapper around wagmi to simplify interactions with smart contracts with typescript autocompletion.
  • 🧱 Components: Collection of common web3 components to quickly build your frontend.
  • 🔥 Burner Wallet & Local Faucet: Quickly test your application with a burner wallet and local faucet.
  • 🔐 Integration with Wallet Providers: Connect to different wallet providers and interact with the Ethereum network.
App demo

Requirements

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

Quickstart

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

  1. Clone this repo & install dependencies
git clone https://github.com/LiskHQ/scaffold-lisk.git
cd scaffold-lisk
yarn install
  1. 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.

  1. 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.

  1. On the same 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.

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

Deploy Contracts to Superchain Testnet(s)

To deploy contracts to a remote testnet (e.g. Optimism Sepolia), follow the steps below:

  1. Get Superchain Sepolia ETH from the Superchain Faucet

  2. Inside the packages/hardhat directory, copy .env.example to .env.

    cd packages/hardhat && cp .env.example .env
  3. Edit your .env to specify the environment variables. Only specifying the DEPLOYER_PRIVATE_KEY is necessary here. The contract will be deployed from the address associated with this private key, so make sure it has enough Sepolia ETH.

    DEPLOYER_PRIVATE_KEY = "your_private_key_with_sepolia_ETH";
  4. Inside scaffold-lisk, run

    yarn deploy --network-options

    Use spacebar to make your selection(s). This command deploys all smart contracts in packages/hardhat/contracts to the selected network(s). Alternatively, you can try

    yarn deploy --network networkName

    Network names are found in hardhat.config.js. Please ensure you have enough Sepolia ETH on all these Superchains. If the deployments are successful, you will see the deployment tx hash on the terminal.

Adding Foundry

Hardhat's NodeJS stack and cleaner deployment management makes it a better default for Scaffold-Lisk.

To add Foundry to Scaffold-Lisk, follow this simple tutorial by Hardhat. We recommend users who want more robust and faster testing to add Foundry.
