Stellar is all about interoperability between financial systems. Our work at the Stellar Development Foundation (SDF) strives to support solutions building system-to-system interplay, while also making those solutions as accessible as possible. Although decentralized finance ecosystems are fertile ground for financial innovation, there is still a gap between the conceptual and the capable. In the urgency of bringing the future of Web3 and DeFi closer to the financial rails of the present, we launched the Stellar Bridge Bounty Program, which endeavors to transform these challenges into changes.

Recently, we’ve seen exciting developments in the space of blockchain interoperability. And we wanted to support projects tackling this important issue, because it's through their work that we’ll make a truly global, interoperable financial system a reality.

That’s why earlier this year we announced the creation of this Bridge Bounty Program. It awards five teams up to $1,000,000 worth of XLM each for incorporating Stellar in a cross-chain solution. That's right — SDF has committed $5,000,000 worth of XLM in total to support projects building interoperability between Stellar and one or more DeFi ecosystems. We believe that supporting builders with programs like this is critical to creating a thriving Web3 ecosystem. By providing developers with the resources they need, SDF is driving towards our mission of creating equitable access to the financial system.

Traditionally, Stellar bridges between payment systems using the network’s on- and off-ramps, a.k.a. Stellar’s anchor network. With the Stellar Bridge Bounty program, we are supporting projects doing the hard work of building bridges between Stellar and the rest of the world. These interoperability solutions may also provide a reference point for how other chains can launch integrations with Stellar in the future.

‍And the winners are…

The number of applications was overwhelming and the decision was hard. Over the past few months, projects from around the world have told us about their business, their mission, and areas of focus. After a healthy deliberation, we are confident these trailblazers are on their way to empowering Stellar as the leading interoperability gateway, providing users of the global financial system with equitable access to innovative DeFi solutions.

The winners are diverse. They vary in terms of technology, product, and team size. Yet they all share three things in common: clear deliverables, concrete timelines, and qualified teams. SDF evaluated each of these applicants' products, services, and code repositories, and we're pleased to present the finalists to you here today.
