Mysten Labs is the web3 infrastructure company that created Sui, a Layer 1 blockchain and smart-contract platform built on the Move programming language, and Walrus, a decentralized blob-storage network coordinated on Sui. Mysten Labs publishes the Sui developer platform: a JSON-RPC (OpenRPC) API, a GraphQL RPC API, and a gRPC (Protobuf) API for reading chain state, querying objects and events, and executing transactions, together with first-party TypeScript, Rust, and Move SDKs, the `sui` command-line interface, dApp Kit, and zkLogin/Enoki authentication tooling. The public full-node RPC endpoints are open (no API key), and the platform is fully open source under Apache 2.0.
