Stellar Development Foundation released the second preview of Soroban, its smart contracts platform, featuring built-in contracts, expanded metering, a new Auth SDK, and significant SDK/CLI improvements including new commands for local development and contract inspection.
The Stellar Development Foundation announced the second preview release of Soroban, a smart contracts platform designed for scalability and developer experience. Key additions include built-in contracts (starting with a standard token contract), expanded metering to cover most contract environment functionality with abstract cost-models, and a new Auth SDK (soroban-auth) for contract authentication compatible with Stellar accounts and Ed25519 signatures. The Soroban-SDK v0.0.4 introduces the contractimport! macro for contract integration testing, generated client interfaces, event emission functions, factory contract deployment capabilities, and new macros for BigInts and Symbols. The Soroban-CLI v0.0.4 adds a local RPC server (serve command), contract state inspection (read command), client code generation (gen command), and shell auto-completion, with contributions from community members.
