Stellar Smart Contract
Smart contracts to build better apps
Stellar Smart Contracts, formerly known as Soroban, provide a powerful tooling for products that bring everyday financial services on-chain.

Ecosystem
Explore the diverse ecosystem building on Stellar
From infrastructure providers and bridges, to protocols and wallets, join projects big and small building the future of DeFi on Stellar.
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.
Scale
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
Leverage Stellar's powerful interoperability by accessing its diverse on-chain assets and global on and off-ramps. Benefit from 5-second smart contract finality on a mature network with 150 real-time 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. Launch 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 $150,000 worth of XLM at a time. SCF rounds run every 4 weeks.
