Welcome to Cairo
A Language for Scaling dApps Using STARKs
A Turing-complete language making it possible for all blockchain developers to harness the power of STARKs
Turing Complete
Cairo is the first Turing-complete language for creating provable programs for general computation.
Efficient
Builtins and field elements enable efficient generation of proofs.
Production Ready
Cairo-based systems are already in production on Ethereum mainnet
