Capi v0.1.0-gamma.0 introduces a robust framework designed for seamless interactions with Substrate chains. This innovative platform comprises a development server and a user-friendly fluent API, empowering developers to engage in multichain operations with optimal performance and simplicity. Capi supports Node 20.3.1+ with built-in Web Crypto API integration, as well as Deno configuration through `import_map.json` with polkadot network compatibility. Developers can easily configure networks using `nets.ts` and leverage Capi’s CLI for efficient command-line operations. Its code generation capabilities allow for swift synchronization of chain-specific APIs, simplifying complex interactions across multiple chains. Capi effectively bridges the gap between app development and specialized, interoperable chain programs, fostering collaboration within the open-source community via its Apache licensed framework. Extensive documentation, guides, and community support are available to ensure comprehensive understanding and contribution.
