MUWP SDK empowers Stellar developers to build cross-chain dApps, handle multiple tokens with ease, and automatically convert them to XLM.
MUWP is a cross-chain liquidity aggregator and bridging solution that simplifies token swaps and expands interoperability across multiple blockchains. By integrating with Stellar’s DEXes, MUWP enables near-instant conversions into XLM or other Stellar-based assets, creating a more accessible route for liquidity to flow into Stellar. In addition, its advanced swap features accommodate scenarios such as merging multiple tokens into a single token or splitting one token into many, ensuring a flexible experience for users managing diverse asset portfolios.
You can already try MUWP’s mainnet solution for Stellar via the MUWP DApp or watch our demo video.
While building out these functionalities, we identified a broader need for user-friendly cross-chain integrations that can be embedded directly into DApps. Many projects want to attract more liquidity to Stellar and streamline asset swaps without forcing their users to leave the DApp environment.
Introducing the MUWP SDK
To address this, we’re developing the MUWP SDK, designed to empower any Stellar-based DApp with seamless cross-chain capabilities. By integrating the MUWP SDK, developers can tap into the multiple liquidity sources and bridging mechanisms we’ve built, turning any DApp into a cross-chain DApp.
This SCF Build Award is aimed at funding the development of that SDK. Below are the key components:

Measurable Usage Growth
We plan to reach 5,000 monthly API calls by the end of the first year, demonstrating steady, real-world usage. High interaction volumes reflect genuine traction and validate the utility of the SDK for subscription management, cross-chain swaps, and payment workflows.
Customer Satisfaction
Our target is an 80% or higher approval rating in bi-annual developer and business surveys. Positive feedback is a direct measure of SDK quality and user experience. Meeting or surpassing this threshold ensures that we continuously refine our product, remain responsive to user needs, and maintain strong retention rates.
Month 1 (after mainnet) – Launch Campaign
The initial focus is to build visibility and bring on early adopters. We will announce the SDK release via social media, Stellar forums, and targeted email campaigns, ensuring the news reaches both existing Stellar communities and broader blockchain circles. Detailed tutorials, documentation, and example code will be published on GitHub and Stellar’s developer portal to help teams get started quickly. A live launch webinar will walk participants through the SDK’s core features, providing an interactive forum for Q&A and early feedback.
Months 2–3 (after mainnet) – Developer Engagement
In this phase, the priority is to spark developer interest and gather real-world insights. We will host a hackathon with prizes for the most creative or impactful uses of the SDK, fueling experimentation and fresh ideas. Real-time support will be offered through Discord and GitHub issues to address developer questions and facilitate rapid troubleshooting. Additionally, a small grant program will reward teams that build meaningful dApps using MUWP, lowering barriers to entry and accelerating SDK adoption.
Months 4–5 (after mainnet) – Partnership Building
Next, we will cultivate partnerships throughout the Stellar ecosystem, engaging wallets, exchanges, and payment platforms to create seamless experiences that leverage MUWP’s multi-token swap and cross-chain features. We will also explore cross-chain collaborations outside Stellar to demonstrate how bridging liquidity and assets can boost project growth. By co-marketing solutions with early adopters, we will showcase tangible use cases and highlight the SDK’s potential to increase user satisfaction and unlock new revenue streams.
Month 6 (after mainnet) – Adoption Scaling
As the user base grows, the goal is to widen our reach, particularly in emerging markets where blockchain solutions can bring considerable value. We will approach SaaS and fintech providers to demonstrate how MUWP can streamline cross-border transactions and reduce operational costs. Case studies of successful integrations will be published to illustrate ROI and best practices. A referral program will provide financial or promotional incentives for developers and businesses to recommend the SDK, solidifying its position as a go-to cross-chain solution within and beyond the Stellar ecosystem.
We have built MUWP across non-EVM networks like Aptos, Partisia, Solana, and Stellar, as well as EVM-compatible blockchains such as Polygon, BSC, Avalanche, Base, Optimism, and Arbitrum. This cross-chain breadth demonstrates our capacity to develop scalable, innovative, and impactful products that capitalize on each ecosystem’s strengths, with particular expertise in interoperability and multi-token management.
A recent survey in October 2024 involving 87 developers, blockchain professionals, and businesses from the USA, France, Luxembourg, and Turkey revealed that 75% faced challenges integrating non-Stellar tokens and 80% sought a more straightforward method for multi-token management and cross-chain transactions. These insights confirm the growing need for the MUWP-Stellar Multi-Token Cross-Chain SDK.
Our existing MUWP DApp already runs on the Stellar mainnet, having garnered more than 2,100 page views in the past year and recording 37 swaps in November alone, underscoring early traction and user interest. Beyond Stellar, MUWP integrates 59 DEXs and 44 bridges, making cross-chain swaps more affordable and efficient for diverse blockchain users. This network of connections positions MUWP as a one-stop platform for streamlined transfers and enhanced liquidity.
Industry recognition further validates our approach. We were selected by 50 Partners, a French VC-led incubator offering high-level mentorship, and we also joined the Chainlink Build Program, which improves our infrastructure for decentralized oracles and cross-chain security. Within the Stellar ecosystem specifically, we have already incorporated Stellar’s DEX for optimizing liquidity flow, begun leveraging Soroban smart contracts for cross-chain transactions, and simplified token issuance and conversion for new Stellar projects.
Our successful deployments on Solana and Aptos highlight our technical depth and ability to adapt to unique blockchain architectures. On Solana, we integrated high-performance liquidity pools to accelerate transaction speeds for cross-chain swaps, and on Aptos we created custom tools and modular SDK components to streamline multi-token swaps in a parallel execution environment. These achievements underscore our commitment to crafting efficient, developer-friendly infrastructure that can likewise benefit the Stellar ecosystem.
By securing the SCF Build Award, we can enhance our SDK, reduce integration hurdles for developers, accelerate multi-token adoption on Stellar, and significantly expand cross-chain liquidity entering the network. Our track record proves our ability to deliver on these promises with technical excellence, making MUWP an asset not just to Stellar, but to the broader blockchain landscape.
