About STARK

StarkWare develops STARK-based validity-proof technology with two scaling products: Starknet, a permissionless decentralized validity rollup for deploying smart-contract dApps, and StarkEx, a standalone validity-rollup service for dApps. StarkEx includes out-of-the-box support for uses such as NFT minting and trading, derivative trading, AMM, spot trading, payments, and DeFi pooling.

For developers, it provides Cairo, a language for creating STARK-provable programs for general computation, which powers Starknet and StarkEx. Its scaling solutions support a range of data availability modes.
