Soroban

Soroban is the smart-contract platform on the Stellar network, letting developers write on-chain programs in Rust. Soroban brings DeFi primitives like lending, AMMs, and yield tokenization to Stellar, and it is the environment Spield’s contracts run in.

Soroban is Stellar’s smart-contract engine. Contracts are written in Rust, compiled to WebAssembly, and run with a resource model and storage system designed for predictable fees and safety.

Soroban is what makes protocols like Blend and Spield possible on Stellar — before it, Stellar had payments and a built-in DEX but not general programmable DeFi.
