This repository offers a collection of example smart contracts specifically designed for ink!, a language utilized for developing Substrate-based smart contracts. It provides a hands-on guide to leveraging ink! by including multiple examples, aiding developers in crafting their own innovative contracts. Contributions to the repository are encouraged via Pull Requests to the integration-tests/public folder, which synchronizes with the repository upon new releases. To build these examples, developers must install and update `cargo-contract` using the `–force` flag for the latest version, enabling efficient contract building and metadata generation through the `cargo contract build` command. The resulting files—a Wasm, metadata.json, and .contract file—are streamlined for instantiation. Furthermore, the repository includes interactive front-end dApp examples facilitated through `pnpm`, allowing developers to run and interact with various contract examples (e.g., ERC20, ERC721), which are all crafted using `useink`, a React hooks library. These examples, released into the public domain, serve as a resource to inspire and empower developers to explore and expand the capabilities of ink!-based contracts.
