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
Cairo 1.0 is the upgraded Rust-inspired version of Cairo, allowing developers to write Starknet smart contracts in a safe and convenient manner.
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
