This template is no longer under active maintenance, it's out-of-date with the state of the ethereum ecosystem. Some reccomendations for replacing this would be to use the Next.js + TypeScript + ConnectKit example from Family, using wagmi directly or web3modal.
This is a default Next.js project bootstrapped with create-next-app, customized as the default boilerplate for new Web3 projects.
- Separate packages from ethers.js for improved tree-shaking, often only ethers Contracts
- Hooks-first approach to fetching and caching data from Contracts and memoization for performance with SWR
- web3-react for ease of connecting to Web3 providers with a solid API
- Auto-generates types for the contract ABIs in the
/contractsfolder via TypeChain
Note: After adding in your new contract ABIs (in JSON format) to the /contracts folder, run yarn compile-contract-types to generate the types.
You can import these types when declaring a new Contract hook. The types generated show the function params and return types of your functions, among other helpful types.
import MY_CONTRACT_ABI from "../contracts/MY_CONTRACT.json";
import type { MY_CONTRACT } from "../contracts/types";
import useContract from "./useContract";
export default function useMyContract() {
return useContract<MY_CONTRACT>(CONTRACT_ADDRESS, MY_CONTRACT_ABI);
}First, run the development server:
npm run dev
# or
yarn devOpen http://localhost:3000 with your browser to see the result.
You can start editing the page by modifying pages/index.js. The page auto-updates as you edit the file.
To learn more about Next.js, take a look at the following resources:
- Next.js Documentation - learn about Next.js features and API.
- Learn Next.js - an interactive Next.js tutorial.
You can check out the Next.js GitHub repository - your feedback and contributions are welcome!
The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.
