🧪 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, and Typescript.
- ✅ Contract Hot Reload: Your frontend auto-adapts to your smart contract as you edit it.
- 🔥 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.
Before you begin, you need to install the following tools:
To get started with Scaffold-ETH 2, follow the steps below:
- Clone this repo & install dependencies
git clone https://github.com/Float-Capital/scaffold-eth-2-envio.git
cd scaffold-eth-2-envio
pnpm install
- Run a local network in the first terminal:
pnpm 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.
- On a second terminal, deploy the test contract:
pnpm hardhat: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 pnpm hardhat: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.
- Ensure docker is running and then on a third terminal, start-up indexer:
pnpm envio:codegen
and then:
pnpm envio:dev
This will run a codegen for your configured envio indexer, it will install all required packages, handle db-migrations and graphql server, and begin indexing your smart contract events.
Visit the hasura console on: http://localhost:8080. You can see the realtime indexing of data in the "data" tab and use the graphql explorer to build queries.
For more info on writing/updating an indexer visit docs.envio.dev/docs.
- On a fourth terminal, start your NextJS app:
pnpm 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 pnpm hardhat:test
- Edit your smart contract
YourContract.solinpackages/hardhat/contracts - Edit your frontend in
packages/nextjs/pages - Edit your deployment scripts in
packages/hardhat/deploy - Edit your envio indexer config.yaml, schema.graphql and EventHandlers.ts in
packages/envio-indexer
