[Music] hey everyone welcome to 2025 hecaton season my name is Elton T and I'm a death r at Circle today I'm excited to introduce you to Circus hackaton bounties at Eve Global and show you how you can build and win prizes this year before we dive into the bounties let's talk about circle circle is a Global Financial technological company that issues us CC the world's largest regulated staple coin Circle also provides stable coin infrastructure and developer tooling to enable businesses and developers to build real world blockchain applications circus Suite of apis sdks and smart contracts makes it faster easier and safer to bring blockchain benefits to your applications whether you're working on payments defy wallets or security Now let's talk about what you came for the Heaton bounties this year we're introducing four bounties designed to challenge you to push the boundaries of what's possible with uscc and circus stable coin infrastructure the first heon Bounty is to build a multi-chain usdc payments system cross chain payments are the future seamless fast and efficient transactions across multiple blockchains will unlock new possibilities for businesses and users that's where you come in we want you to build an application that enables cross chain uscc payments using the newly released cctp V2 show us how payments should work in a truly interconnected ecosystem this track will have two winners each receiving $2,000 the second hecaton Bounty is to enable end users to pay for gas using usdc let's face it gas fees are huge barrier for mainstream adoption but what if users could pay for gas directly with uscc skipping the need for Native tokens that's exactly what Circle pay Master enables your challenge is to integrate Circle pay Master into an application that makes transactions smoother with usdc if you can show us a creative way to eliminate friction you can walk away with $2,000 the third hackaton Bounty is to build a smart w wet with Dynamic security controls security is a must have not an afterthought with modular wallets and circus compliance engine you can build a smart wallet that adapts to your security needs think multiactor authentication pass keys or transaction monitoring all buil directly into your wallet experience design a wallet that puts security and usability first and you could be our next Bounty winner of $2,000 the last hecon Bounty is Implement hooks for cctp v2 transfers imagine a world where cross chain in transactions trigger automated actions without manual intervention with cctp hooks you can program workflows that activate once a cross chain uscc transfer has been completed we are looking for automation that makes cross chain Finance smarter and the best solution will walk away with $2,000 to qualify for any of these bounties your submission must meet the following requirements first a functional MVP and architecture diagram so your project must demonstrate working front end back end and be accompanied with a clear architecture diagram number two a video demonstration and presentation please come to us and present your work explain clearly your project how integrate circus developer tooling and include your supporting documentation number three GitHub or repli repository provide a publicly accessible repository with clean and well documented code so these are the three main requirements that you should meet additionally be sure to clearly state which Bounty you submitting for as part of your submission so that's it whether you're hacking Solo or with a team we can't wait to see what you build push limits be creative and make an impact wishing you all the best and most importantly happy hacking [Music]
