The FraxBuild Hackathon has just announced its winners and we want to give a big congratulations to the 8 amazing teams that came out on top! FraxBuild hackathon drew in a total of 32 project teams, really raising awareness about building on Frax and getting more folks involved in the developer community. The winning teams were split across three different tracks: Product Expansion, Consumer Adoption, and Data Analytics. They all built some super cool products and primitives that fit perfectly with the Frax ecosystem of stablecoins and primitives. So, let's take a closer look at these projects and see what they're all about!\n\n# Track: Product Expansion\n\n### 🥇First Prize\n\n**[Fraximal](https://dorahacks.io/buidl/6498)**\n\nOptimize FraxLend Lending Yield\n\n### 🥈Second Prize\n\n**[Revest Protocol veFXS/ veFPIS](https://dorahacks.io/buidl/6616)**\n\nLiquid Staking NFT for ve-FXS/FPIS\n\n### 🥉Third Prize\n\n### **[Zaros](https://dorahacks.io/buidl/6609)**\n\nPerps powered by LSTs.

Currently, the three stablecoins issued by Frax are FRAX (dollar-pegged), frxETH (ETH-pegged), and FPI (CPI-pegged) while subprotocols include Fraxlend, Fraxswap, and Fraxferry. FRAX is one of the largest decentralized stablecoins in existence with over $1 billion in circulation, frxETH has been able to become the largest LSDs with 128k validators live today, and FPI pioneered the concept of a stablecoin that is pegged to the consumer price index that is resistant to inflation. \n\nFrax has been able to build a microcosm of DeFi within itself with a core team of devs in the single digits. Although they have been able to make great strides in development over the past few years, there is still much to be built and the Frax team cannot do it alone. That is why we are excited to announce FraxBuild, the first ever official hackathon of the Frax ecosystem. The goal for this hackathon is to:\n\n- Increase dev awareness of building on Frax and engaging with the developer community\n- Build products and primitives that compliment the Frax ecosystem of stablecoins and primitives\n- Educate developers about how they can integrate Frax into their protocols\n\nFraxBuild is co-hosted by Frax Finance, Flywheel DeFi, and DoraHacks. From May 29th to July 25th, applicants will be able to submit their applications online for a chance to win over $50k worth of prizes in $FXS. Winner of the hackathon will be interviewed and have their product demo’don Flywheel DeFi.\n\n# Chat and Get Support! \n\nBtw, don't miss out on the Idea Board tab! It's your go-to spot for valuable tips, idea sharing, team forming, advice and feedback, etc. Get inspired and inspire others as you embark on this amazing hackathon journey ✨\n*You need to click \"Register as a Hacker\" via the above button to post. \n\nIf you have any question, you can also leave it on the Idea Board page or contact DoraHacks user support account at Telegram @dorahacksofficial. \n\n# Key Dates\n\n

Launching in late 2020, Frax pioneered several concepts in DeFi including the hybrid stablecoin model and Automated Market Operations as well as ideas The DeFi Trinity and Stablecoin Maximalism. With a positive sum mentality, Frax Finance has been able to grow into one of the premier DeFi ecosystems with billions of dollars worth of stablecoins issued and hundreds of millions of dollars in TVL locked in its family of subprotocols.\n\n# Links\nhttps://frax.finance/\nhttps://docs.frax.finance/\nhttps://github.com/FraxFinance/frax-solidity\nhttps://t.me/fraxfinance","onboardingCompleted":false,"registerFormUrl":null,"preRegisterTime":0,"publicContactHackerHandle":null,"hackersCount":123,"winnerAnnounced":false,"teamCount":0,"title":"FraxBuild Hackathon","uname":"fraxbuild","imageUrl":"https://cdn.dorahacks.io/static/files/1894f991b13b9d8e28e36a846ca9f628.png","originUrl":null,"startTime":1685343600,"endTime":1691038800,"timezone":"420","city":null,"visible":true,"approvalStatus":6,"state":0,"voteUrl":null,"voteMechanism":null,"bonusPrice":50000,"bonusMechanism":null,"followersCount":0,"ecosystem":"Frax","applyGuide":null,"weight":0,"participationForm":"Virtual","field":"Stablecoins,DeFi","email":"dave@flywheeldefi.com","contacts":"Telegram,defidave222","externalContacts":null,"telegram":null,"discord":null,"whatsapp":null,"wechat":null,"prizeFundingEscrowed":0,"token":"USD","prizeSafeForm":0,"prizeSafeNetwork":null,"prizeSafeOwner":null,"prizeSafeWallet":null,"prizeSafePublishDate":null,"hasOnboarding":false,"isPublicTrackJudging":false,"isEndedTrackJudging":false,"question":null,"countryId":null,"cityId":null,"venueName":null,"venueAddress":null,"category":0,"isEnableBounty":true,"isBountyRequired":false,"isEndedBountyJudging":false,"bountiesLimitForBuidl":10,"isPublicBountyJudging":false,"isMultiTracksAllowed":false,"tracksLimitForBuidl":0,"showIdeaTab":true,"showQuestionTab":true,"showTeamTab":false,"bonusDescription":[],"askHackers":[],"isEnabledQuestions":false,"isEnabledAskHackers":false,"isBuidlsPrivate":false,"trackJudgingMaxScore":100,"bountyJudgingMaxScore":100,"isExtended":false,"oldEndTime":null,"status":2},"status":4,"bounty":null,"track":null,"table":"0","trackObj":{"id":229,"name":"Consumer Adoption","judgingCriteria":"","weight":0},"bountyObjs":[]}],"chain":[],"chainList":[],"appliedGrant":false,"acceptRewards":false,"owner":47102,"ownerInfo":{"nickname":"junhoyeo","username":"junhoyeo","avatar":"https://cdn.dorahacks.io/static/files/194697b9dd5e6652d2865f14c14ac092.png"},"visible":true,"deleted":false,"continuousSponsoring":false,"pageView":0,"sponsoredCount":0,"starCount":0,"sponsoredAmount":"0.00","sponsoredPersons":0,"followers":0,"voteCount":0,"projectMembers":[],"bnbRound":null,"doraGrantDaoTags":[],"techTrees":[0],"infrastructureTags":[42,81,84,85],"otherInfrastructures":[],"lastEditor":{"id":47102,"username":"junhoyeo","date":1723749151000},"upvoted":false,"followed":false,"upvoters":{"count":1,"list":[{"id":3692,"hacker":{"username":"junhoyeo","avatarUrl":"https://cdn.dorahacks.io/static/files/194697b9dd5e6652d2865f14c14ac092.png","nickName":"junhoyeo","introduction":"Generalist hacker, designer, and dreamer"},"createdAt":"2023-07-27T16:55:30.470338+08:00","upvotes":"0.00","followed":false}]},"kycStatus":0,"ideas":[],"name":"¤ FraxPay by Inevitable","techniqueField":"","source":"-","vision":"FraxPay enables merchants and content creators to accept payments in Frax Stablecoins seamlessly.","projectDescription":"# ¤ FraxPay by Inevitable\n\n**FraxPay** was built during the **Hackathon [FraxBuild 2023](https://dorahacks.io/hackathon/fraxbuild/track) under the Consumer Adoption Track**, enabling merchants and content creators to accept payments in Frax Stablecoins seamlessly.

Payments to the merchant occur in real-time within the function, based on the verified amount in the backend.\n\n![FraxPay - Input Shipping Info](https://github.com/0xinevitable/FraxPay/raw/main/.github/assets/shipping-connect-1.png?v=2)\n\n> Input Shipping Information. _Supported values: Name, Email, Address(Country, City, Street Address and ZIP/Postal Code), Phone Number_\n\n![FraxPay - Connect Wallet(Example: Coinbase Wallet Provider)](https://github.com/0xinevitable/FraxPay/raw/main/.github/assets/shipping-connect-2.png?v=2)\n\n> Connect Wallet (Example: Coinbase Wallet Provider)\n\n![FraxPay - Wallet Connected](https://github.com/0xinevitable/FraxPay/raw/main/.github/assets/connect-wallet.png?v=2)\n\n> Wallet Connected View: We display the same avatar as MetaMask for easy distinction, ensuring user safety. 😆\n\n![FraxPay - Insufficient Balance: Swap with `FraxSwapRouterV2`](https://github.com/0xinevitable/FraxPay/raw/main/.github/assets/insufficient-amount-swap.png?v=2)\n\n> Insufficient Balance: Swap with `FraxSwapRouterV2`\n\n![FraxPay - Insufficient Balance: Onramp](https://github.com/0xinevitable/FraxPay/raw/main/.github/assets/insufficient-amount-onramp.png?v=2)\n\n> Insufficient Balance: Onramp. \\_Options: [Stably](https://stably.io/) and [Transak](https://transak.com/).\\_\n\n![FraxPay - Done](https://github.com/0xinevitable/FraxPay/raw/main/.github/assets/done.png?v=2)\n\n> Done! 🎉\n\n## 🔴 Deployments\n\n### FraxPay\n\n- Optimism(`FraxPayCore`): `0x986ec2aeE73E21B28b29A2E040DDFfd839F6F07d`\n- Optimism(`FraxPayPeriphery`): WIP\n\n### Ecosystem\n\n- Optimism(`Frax Token`): `0x2E3D870790dC77A83DD1d18184Acc7439A53f475`\n- Optimism(`FraxSwapRouterV2`): `0xB9A55F455e46e8D717eEA5E47D2c449416A0437F`\n\n## 🛠️ Contributing\n\n### Setup Environment Variables\n\n```conf\n# contracts/.env\nPRIVATE_KEY=\n```\n\n```conf\n# interface/.env\nJWT_SECRET=\nNEXT_AUTH_SECRET=\nUPSTASH_URL=\nUPSTASH_TOKEN=\nNEXT_PUBLIC_SIGNIN_MESSAGE=\"Sign In to FraxPay\"\nNEXT_PUBLIC_OPTIMISM_ALCHEMY_API_KEY=\n```\n\n### Run!\n\n```bash\n# install dependencies\nyarn\n```\n\n```bash\n# start frontend dev server\nyarn workspace interface dev\n```","images":["https://cdn.dorahacks.io/static/files/189908bbcdeeb351aac2cac45dd8a22f.png"],"team":"Junho Yeo is a developer/designer who mostly code 24/7 and just like to hack, build, and ship mind-breaking things, such as [the first unofficial, reverse-engineered client for Meta(Instagram)'s Threads](https://github.com/junhoyeo/threads-api), or crafted frontends like [my personal website with an iPhone on the web](https://junho.io/about), some crypto stuff like an [open-source DeFi dashboard](https://github.com/inevitable-dao/bento), or [regularly scraping the NIKE Draw Calendar to get my hands laid on a brand new Jordan 1 Retro Low OG SP Fragment x Travis Scott](https://github.com/junhoyeo/NIKE-THE-DRAW-Calendar).\nHe's leading Inevitable, a team of builders which aims to fail fast & fail forward.","github":"https://github.com/0xinevitable/FraxPay","demo":"https://fraxpay.vercel.app","video":null,"socialTwitter":"0xinevitable","socialFacebook":null,"socialInstagram":null,"nftId":null,"haxonBuidls":[{"id":6567,"projectId":6835,"name":"¤ FraxPay by Inevitable","track":"Consumer Adoption","bounties":[],"haxonId":127,"haxonName":"FraxBuild Hackathon","status":2,"haxonCreateAt":"2023/05/29 07:00:00 UTC"}],"kudoData":null,"bountyObjs":[],"tracks":[],"badges":["{\"schema\":\"BADGE\",\"d\":{\"index\":\"b5567\",\"badgeType\":\"buidl\",\"path\":\"/buidl/6835/achievement/b5567\",\"ownerId\":6835,\"iconName\":\"b0\",\"updatedDate\":\"2023/07/26\",\"title\":\"FraxBuild Hackathon\",\"detail\":\"Participation\",\"tag\":\"Hackathon\",\"imageUrl\":\"https://cdn.dorahacks.io/static/badge/b0_FraxBuild~c32Hackathon.webp\",\"shareImageUrl\":\"https://cdn.dorahacks.io/static/badge/b0_FraxBuild~c32Hackathon.jpg\",\"id\":5567,\"metaInfo\":{\"type\":\"HACKATHON_PARTICIPATION\",\"hackathonId\":127,\"title\":\"FraxBuild Hackathon\"},\"createdAt\":1690347340,\"updatedAt\":1690347340,\"type\":0,\"subjectId\":127,\"metadata\":{},\"buidl\":6835}}"]}}
