Strict TypeScript types for Ethereum ABIs

// ^? type FunctionNames = "symbol" | "name" | "allowance" | "balanceOf" | "decimals" | "totalSupply" type TransferInputTypes = AbiParametersToPrimitiveTypes< // ^? type TransferInputTypes = readonly [`0x${string}`, bigint] ExtractAbiFunction['inputs'] > ``` Works great for adding blazing fast [autocomplete](https://twitter.com/awkweb/status/1555678944770367493) and type checking to functions, variables, or your own types. No need to generate types with third-party tools – just use your ABI and let TypeScript do the rest! ## TL;DR ABIType might be a good option for your project if: - You want to [typecheck](https://abitype.dev/api/types) your ABIs or EIP-712 Typed Data. - You want to add type inference and autocomplete to your library based on user-provided ABIs or EIP-712 Typed Data, like [Wagmi](https://wagmi.sh) and [Viem](https://viem.sh). - You need to [convert ABI types](https://abitype.dev/api/utilities#abiparameterstoprimitivetypes) (e.g. `'string'`) to TypeScript types (e.g. `string`) or other type transformations. - You need to validate ABIs at [runtime](https://abitype.dev/api/zod) (e.g. after fetching from external resource). - You don’t want to set up a build process to generate types (e.g. TypeChain). ## Documentation For documentation and guides, visit [abitype.dev](https://abitype.dev). ## Community For help, discussion about best practices, or any other conversation that would benefit from being searchable: [Discuss ABIType on GitHub](https://github.com/wevm/abitype/discussions) For casual chit-chat with others using the library: [Join the Wevm Discord](https://discord.gg/SghfWBKexF) ## Sponsors If you find ABIType useful or use it for work, please consider supporting development on [GitHub Sponsors](https://github.com/sponsors/wevm?metadata_campaign=abitype_readme) or sending crypto to `wevm.eth`.
