description: StarkWare Industries builds STARK-proof (Scalable Transparent ARgument of Knowledge) blockchain scaling technology
  for Ethereum. Its flagship products are Starknet, a permissionless decentralized validity-rollup (ZK-Rollup) where developers
  deploy Cairo smart contracts, and StarkEx, an application-specific scaling engine for exchanges (spot, perpetual, NFT, and
  payments). The developer surface centers on the Starknet Node JSON-RPC API (read, write, trace, and WebSocket methods specified
  in OpenRPC), a Wallet JSON-RPC API, a Proving API, StarkEx REST gateways, first-party SDKs (starknet.js, starknet.py, starkex-js),
  the starkli CLI, and the Cairo programming language and prover stack (Stwo, Cairo VM). This profile catalogs those machine-readable
  specs and developer artifacts for the API Evangelist network.
