Core gaming backend SDK for play-to-earn games on Stellar.

AirGap

AirGap allows users to turn a spare smartphone into a fully offline cold wallet using a two-device architecture: AirGap Vault (offline) for key generation and transaction signing, and AirGap Wallet (online) for transaction creation and broadcasting. Communication between the two devices happens exclusively via QR codes, ensuring that private keys never touch an internet-connected device. And, there's much more to it. Check out our docs to know all about AirGap and it's security features - support.airgap.it.

Cubist

Cubist is a developer toolkit for building cross-chain and multi-chain Web3 applications, automating bridge code generation for seamless blockchain interactions. It supports popular blockchains like Ethereum and offers secure transaction signing with CubeSigner.

WebSoroban IDE

Browser-based IDE for Soroban smart contract development, enabling writing, compiling, and deploying contracts without local toolchain setup.

Stellar Unity Developer Kit

Stellar Unity Developer Kit is a Unity SDK for building blockchain games on Stellar, with wallet management, token interactions and NFT support so game studios can integrate Soroban into video games. SCF-awarded gaming developer tooling for on-chain / GameFi and play-to-earn titles on Stellar.

Stellar Router SDK

A set of "meta contracts" developers can use to avoid uploading contracts just to do complex calls from their dApps.

SorobanMath

Fixed-Point Math Library for soroban smart contracts with advanced math and high precision.

SocketFi

SocketFi is a smart wallet dApp built on Soroban and the Stellar ecosystem, designed to seamlessly connect millions of users to Web3. It provides a non-custodial alternative to traditional wallets, enabling smart wallet creation through passkey sign-in with social profile binding. This removes the complexity of private key management and simplifies blockchain adoption for everyday users. By leveraging passkeys, SocketFi significantly reduces onboarding friction, allowing social media users unfamiliar with blockchain to securely access Soroban and Stellar. Key features include passkey authentication with social account binding and gas abstraction, enabling limited gas-less transactions and flexible fee payment in supported tokens rather than only XLM. Recognizing that most internet users are mobile-first, SocketFi is also developing a mobile application tailored to millions of smartphone users. The mobile app will provide the same core features already available on the web platform, ensuring seamless and secure access to Soroban dApps directly from mobile devices.

Sentinel

Sentinel Protocol is a parametric insurance framework built on the Soroban blockchain, enabling trustless, automated coverage through smart contracts and decentralized oracles. It can support insurance in any vertical with a reliable data source. The first vertical we are building is flight delay insurance, which offers travelers automatic payouts if a flight is delayed beyond a set threshold, with no claims process or approvals.
