Soroban
Soroban (XLM) is Stellar’s smart contract platform, finalized through the Stellar Consensus Protocol’s federated Byzantine agreement, with smart contracts activated on mainnet by Protocol 20 on February 20, 2024. Contracts are written in Rust and compiled to WebAssembly, while persistent contract data is stored in Stellar ledger entries that Core nodes replicate alongside accounts, balances, offers, and other state. Because Soroban extends the existing Stellar ledger rather than creating a separate chain, its contract interface shares transaction and ledger primitives with the wider Stellar network.
Soroban API Methods and Endpoints
NOWNodes exposes Soroban's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions.
Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
