Stellar RPC API
The Stellar RPC API (formerly Soroban RPC) is a JSON-RPC interface for interacting with Soroban smart contracts deployed on the Stellar network. It supports simulating and submitting contract invocations, reading contract state and ledger entries, and streaming network events. The RPC service is the primary interface for Soroban contract developers and complements Horizon by exposing contract-specific data not available through the Horizon REST API.
