Haskell is a declarative, statically-typed, general-purpose programming language used for Cardano smart contract development.
Open-source
What is Haskell?
Haskell is a purely functional programming language that serves as the main smart contract language for the Cardano blockchain. It features referential transparency, immutability, and lazy evaluation. Developers can take advantage of the concurrency features of Haskell to build Cardano smart contracts that perform faster than alternative chain languages. The strong type system and declarative style help catch mistakes before they reach production and keep codebases maintainable as requirements evolve.
