A Haskell library implementing API clients for Ethereum and other Web3 platforms.
hs-web3 is a Haskell library that implements API clients for Ethereum and other Web3 platforms. It provides a type-safe interface for interacting with blockchain networks, enabling developers to query data, send transactions, and integrate with services like ENS. The library solves the problem of building reliable, maintainable decentralized applications in Haskell.
Haskell developers building decentralized applications, blockchain tools, or backend services that need to interact with Ethereum or other Web3 platforms.
Developers choose hs-web3 because it leverages Haskell's strong type system and functional programming features to create safer, more predictable blockchain interactions with compile-time validation and clear error handling.
Web3 API for Haskell
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Leverages Haskell's strong type system for compile-time validation of blockchain operations, as seen in the code with typed parameters like `Latest` for block references.
Provides built-in functions for resolving Ethereum Name Service addresses, simplifying human-readable interactions using `Ens.resolve` as shown in the usage example.
Uses clear result types (e.g., `Left`/`Right`) for Web3 operations, reducing runtime errors and improving debuggability, demonstrated in the error handling snippet.
Includes utilities for converting between Wei and Ether, making value management straightforward with functions like `fromWei` in the example code.
Has a smaller community and fewer third-party plugins compared to mainstream Web3 libraries like web3.js, which can limit extensibility and support.
Requires proficiency in Haskell and functional programming concepts, such as monads and type classes, which may deter developers from imperative backgrounds.
Installation and configuration via Stack or Cabal can be more involved than package managers like npm, potentially slowing initial development and onboarding.
