Soroban Platform

Smart Contracts to Build Better Apps

Powerful tooling for products that bring everyday financial services on-chain


Designed For


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.

Grants & Funding

$100M Adoption Fund

The Stellar Development Foundation launched the $100M Soroban adoption fund to encourage and support developers as they learn, experiment, build, and scale projects on Soroban. Kickstart your project with supporting programs like the Stellar Community Fund (SCF), an open-application awards program to support developers and startups building on the Stellar network and Soroban. Qualified submissions may receive awards of up to $100,000 worth of XLM at a time. SCF rounds run every 4 weeks.


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.

use soroban_sdk::{contract, contractimpl, symbol_short, vec, Env, Symbol, Vec};

pub struct HelloContract;

impl HelloContract {
    pub fn hello(env: Env, to: Symbol) -> Vec<Symbol> {
        vec![&env, symbol_short!("Hello"), to]

mod test;
