Soroban Smart Contracts

A developer-friendly, Rust-based smart contracts platform designed for scale and sensibility.


Designed For


Builders With tools such as plug-and-play SDKs, Soroban CLI, RPC server, and local sandbox, Soroban provides a user-friendly experience that gets developers up and running quickly. Start building with flexible, reusable functions and ready-to-use contracts.


Soroban is designed with scalability in mind. Boost performance with multi-core scaling, an optimized fee model, and without pesky serialization loops. Soroban also tackles the elephant in the room head-on by addressing the problem of state bloat.

Real-World Utility

Connect to Stellar’s exceptional interoperability by accessing its wide variety of on-chain assets and worldwide on and off-ramps. Also, benefit from five-second contract finality on a proven and mature network boasting 150 TPS.


Protocol 20 Release Schedule

Protocol 20 marks the most transformative upgrade to the Stellar network to date. And to preserve the network's performance, security, and stability during this time, the ecosystem has agreed that a slow and steady process makes a lot of sense. So, following the upgrade vote, validators will deploy a phased approach to gradually and responsibly increase capacity for Soroban transactions to monitor the impact of smart contract functionality on the network.


Install & Learn

Install the Rust toolchain and Soroban CLI to begin writing your first Soroban smart contract. Learn more and continue building by going to the Soroban documentation. Or check out all available Soroban-related learning materials, programs, and more in Sorobanland.
