\n### Bounty Value\nTotal Value: $5,000 USD\n\nAwards (per bounty):\n- First Place: $1,500\n- Second Place: $1,000\n\n### Quantity of Available Bounties\n\n4\n\n### Description\n\n****Defender Tooling****\\\nOpenZeppelin Defender is a security, automation, and operation Web3 platform, designed to enable projects to code, audit, deploy, monitor, and operate blockchain applications with confidence. We want to integrate and improve developer workflow for all teams, from small startups to established organizations. We have a few ideas that we think would benefit the entire ecosystem:\n- ****Deploy from Remix using Defender Deploy API****
\nWe know a lot of people start their Solidity journey on Remix, and even experienced developers use it to quickly prototype and test. To improve the developer experience, we want to allow projects to leverage the security and functionality of [Defender Deploy](https://docs.openzeppelin.com/defender/v2/module/deploy) directly from the Remix application.\n\nThe challenge for you is to build a Remix plugin that allows you to deploy smart contracts using Defender Deploy behind the scenes.\n\n- ****Seamless Multi-chain Deployments****
\nAs Ethereum scales through its wonderful and vibrant L2 community, some projects decide to deploy to multiple chains to leverage users and liquidity. Defender already makes this process easier by allowing you to manage your deployments as a whole using [environments](https://docs.openzeppelin.com/defender/v2/module/deploy#environments) and support for deterministic deployments using CRATE2 to ensure a contract will be assigned to a specific address.\n\nBut there's still a struggle these projects face. If you want to deploy across multiple chains you have to fund the Relayer on each L2 and manage the funds yourself (besides having to run the script multiple times - one per each chain).\n\nThere are two things we would like to see you build (they are separate challenges, but bonus points if you manage to solve the two):\n\n- ****Multi-network Deploy****
\nAllow users to deploy to multiple networks with a single API request. The idea is that the user specifies the networks he wants to deploy to and that the contract is deployed across those chains on the same address.\n\n- ****Defender Relayers Advanced Funds Management****
\nUsers often prefer to use our Relayers service to easily sign and submit on-chain transactions, also when deploying a contract. However, when deploying across multiple networks, users need to create, fund, and manage a Relayer per each network.\n\nThe challenge for you is making this process more seamless by managing the deployment and gas across multiple chains transparent to users by automatically swapping funds from one Relayer to another to pay for gas. This will allow users to deposit funds to a single Relayer and then use those funds to pay for gas to deploy their contracts to any supported network.\n\nFor these you will probably need to fork the defender-sdk, you can find the code [here](https://github.com/OpenZeppelin/defender-sdk).\n\n- ****General Open Source Tooling****
\nAbove are two ideas that we strongly believe will benefit the entire community if built, but we know there are tons of other great things that can be built. So if you think you have a great idea for a plugin or other open source component that uses Defender we are looking forward to seeing it! Our only ask is that it must use Defender and preferably if it integrates with other tools they are widely adopted open source projects in the web3 ecosystem.\n\n****DeFi with Defender****\n\nUse Defender to automate or secure an existing or new DeFi application. You must highlight how you used the different Defender components inside your project. Some ideas and examples:\n\n- Monitor oracles (like TWAPs) to get alerts if they are being manipulated (for example, using deviation)\n- Create an action that automates a protocol operation per N blocks\n- Rebalance Uniswap positions automatically with Monitors and Actions\n- Create a Workflow that pauses a protocol if there's a lot of token outflows for hacks or suspicious activity\n- Arbitrage bots (like CEX/DEX arbitrage) with Monitor and Actions\n- Combine Relayers with Account Abstraction for interactions with DeFi protocols\n\n### Requirements\n\n- Use Defender and/or the Defender SDK, Defender as Code.\n- Your source code must be public on a GitHub repository\n\n### Judging Criteria\n\n****Technical Complexity and Innovation****\\\nHow complex is the problem being addressed, and how sophisticated is the approach to solving it? How innovatively has Defender been used? How well did the team overcome technical challenges?\n\n****Originality and Creativity****\\\nIs the project tackling a new or unsolved problem, or does it create a unique and creative solution to an existing problem? How well did the team think outside the box and develop an original concept with Defender?\n\n****Functionality and Completeness****\\\nHow complete and functional is the project within the given timeframe? Are the core features implemented and working as intended?\n\n****UX/DX/UI****\\\nIs the project intuitive and easy to use? How much effort did the team put into creating a user-friendly interface and removing friction points?\n\n****Impact and Potential****\\\nWhat is the project's potential to make a positive impact on the developer ecosystem on Scroll and Defender? How scalable and viable is the solution in the long-term? How effectively does it solve the identified problem?\n\n### Helpful Links\n[Defender Docs](https://docs.openzeppelin.com/defender/v2/)\\\n[Defender Deploy](https://docs.openzeppelin.com/defender/v2/module/deploy)\\\n[Hardhat](https://github.com/OpenZeppelin/openzeppelin-upgrades)\\\n[Foundry](https://github.com/OpenZeppelin/openzeppelin-foundry-upgrades)\\\n[Defender Relayers](https://docs.openzeppelin.com/defender/v2/manage/relayers)\\\n[Defender SDK](https://github.com/OpenZeppelin/defender-sdk)\\\n[Defender API](https://www.api-docs.defender.openzeppelin.com)\\\n[Defender as Code](https://docs.openzeppelin.com/defender/v2/dac)\\\n[Remix Plugins](https://github.com/ethereum/remix-plugin)\n\n\n# Sindri\n\n### Title\nMost unique uses of Sindri\n\n### Bounty Value\nTotal Value: $6,000 + Sindri Credits\n\nAwards:\n- Top 3: $2K USD each + 10 hours of Sindri Credits\n- Teams 4 through 10: 5 hours of Sindri Credit for submissions\n\n### Quantity of Available Bounties\n\n10\n\n### Description\n\nSindri is the ZK Developer Cloud providing builders with accessible, streamlined infrastructure often required for developing, deploying and scaling ZK. With the rise of zkML, offchain applications, rollups, and Layer 2s, teams are confronted with increasingly difficult infrastructure requirements, storage, and cloud configuration for building and deploying with ZK. Sindri abstracts away these complexities and overhead and turns your cloud builds into a few API calls.\n\nBuilders will find engaging with Sindri is very much like a Web2.0 developer experience. Similar to how a developer might interface with Infura or Stripe, Sindri is also integrated via API. This means you can build ZK infrastructure right into application or protocol logic or the browser front end. To make iteration even easier, we've integrated Sindri into Remix IDE.\n\nThe Sindri API offers out-of-the-box, serverless proving deployments, adaptable support for your favorite proving systems with minimal refactoring required, built-in acceleration, and SDK/CLI tooling to deliver a phenomenal developer experience mirroring to the CI/CD workflows you're already accustom to. Develop and deploy amazing ZK applications in minutes instead of weeks or months without the hassle of having to spin up, configure and maintain generic cloud resources.\n\nWe've built Sindri from a place that respects the builders and coders who need accessible, reliable infrastructure solutions to share their life work. We're excited to share it with you.\n\n### Requirements\n\nTrack agnostic, so long as the team meets the requirements outlined below:\n\n- A submission that leverages ZK and Sindri's API and versatility. Your project should utilize one of Sindri's supported proving systems, including Gnark, Noir, Halo2 (Axiom), and Circom, to build something truly unique. zkML, coprocessors, AI agents, interoperability solutions, payment gateways, DePIN, and more have all leveraged Sindri.\n- Our Python, Javascript, and Typescript SDKs and tooling allow you to build proving logic directly into the application layer, streamlining access to Sindri's scalable, accelerated infrastructure stack. In turn, developers can build with large circuit structures and unexpected, high-volume request spikes, which are often challenging in ZK applications.\n- Looking for a starting point? Browse the How-To Guides in our docs for examples of (links in the \"Helpful links\" section).\n- Circom + Python + Sudoku\n- Gnark + Javascript + String Compression\n- Halo2 + Rust + Floating Point Arithmetic\n- Noir + Javascript + PageRank\n\n### Judging Criteria\n\n- New projects only, please (one submission per prize category; it's okay to use pre-written open-source components, but specify what is original to this project)\n- Must have Sindri integrated into the submission\n- Must leverage Sindri for proof generation\n- Ability to support multiple or concurrent proof request environments preferred (e.g., end users requesting proofs at scale, scheduled proof generation, etc)\n\n### Helpful Links\n[Quickstart](https://sindri.app/docs/quick-start)\\\n[CLI tutorial](https://sindri.app/docs/getting-started/cli)\\\n[Python SDK](https://sindri.app/docs/reference/sdk/python)\\\n[Typescript SDK](https://sindri.app/docs/reference/sdk/ts)\\\n[Smart Contract Generation](https://sindri.app/docs/reference/sdk/python/#function-get_smart_contract_verifier)\\\n[Supported Proving Systems](https://sindri.app/docs/how-to-guides/frameworks)\\\n[Example Use Cases](https://github.com/Sindri-Labs/sindri-resources/tree/main/circuit_tutorials)\\\n[Remix Integration](https://sindri.app/docs/external-resources/remix)\n\n\n# The Graph\n\n### Titles\n- Best New Subgraph(s)\n- Best Use of Existing Subgraph(s)\n\n### Bounty Value\nTotal Value: $5,000\n\nAwards:\\\nBest New Subgraph(s)\n- 1st Prize $1.6k\n- 2nd Prize $1.1k\n\nBest Use of Existing Subgraph(s)\n- 1st Prize $1.4k\n- 2nd Prize $900\n\n### Quantity of Available Bounties\n\n4\n\n### Description\n\n****Best New Subgraph(s)****\\\nBuild and deploy a custom subgraph that indexes data from a smart contract to query blockchain data for your dapp.\n\n****Best use of Existing Subgraph(s)****\\\nQuery an existing subgraph on the Graph Explorer or hosted service using the public query URL from the subgraph dashboard.\n\n### Requirements\n\nBest New Subgraph(s):\n- Link to the deployed subgraph\n- Link to the subgraph source code\n- The project should be using data indexed and queried using the subgraph\n\nBest Use of Existing Subgraph(s):\n- The project should be using data from an existing subgraph\n\n### Judging Criteria\n\n****Technical Implementation****\\\nThis criteria evaluates the skilful execution of The Graph protocol within the project.

Verifying their identities on Iris-I allows users to generate zk proofs of their identities that they can submit and use on services that use Iris-I as a documents and identity verification tool. Iris-I develops on decentralised identities (DID) where it allows users the flexibility of not having to identify themselves repeatedly on every new platform that they sign up to.\n\n[BUIDL](https://dorahacks.io/buidl/11662)\n\nBUIDL link: https://dorahacks.io/buidl/11662\n\nCrypto Battlefield it a crypto game based on your skills, ZK proofs and the price of tokens.\n\n[BUIDL](https://dorahacks.io/buidl/11840)\n\nBUIDL link: https://dorahacks.io/buidl/11840\n\nPocket is an application designed to help parents manage their children's pocket money.

In this track you’re building anything related to DeFi. As a suggestion, we challenge you to build a project that makes DeFi accessible to a mass audience, especially those who are new to web3 and non-technical. Some ideas include, but not limited to:\n\n- Decentralized Options AMM with deep liquidity and innovative incentives\n- Perps DEXs with superior UX thanks to account abstraction smart wallets (social login)\n- Decentralized exchanges with enhanced features (Uniswap hooks, other ideas)\n- Yield farming platforms with ZK-proofs for secure yield calculations\n- Just something nerdy, build with cool tech and might not even be useful\n\n**Gaming**\\\nGames built on-chain are now possible with vanilla Solidity or Solidity-based game engines. Game development is no joke, and you don’t have to spend your time building a full-scale game. Your goal is to showcase the unique benefits that blockchain and ZK offer to the world of gaming in innovative and creative ways. Some ideas include:\n\n- On-chain games with provably fair reward distribution and verifiable randomness/verifiable computation\n- On-chain games with privacy-enriched gameplay (eg. private attributes on a character that will only be revealed after battle. eg games like [Dark Forest](https://zkga.me/))\n- Games powered by ZK-proofs\n- Or just a simple card game where you embarrass your friends\n\nHere are some examples of games built at a hackathon:\n\n1. https://github.com/razacodespython/ethseoul\n2. https://github.com/razacodespython/ethgloballondon2024/tree/main/diginouns\n3. https://ethglobal.com/showcase/shadow-warfare-gxvty\n\n**Privacy**\\\nZK allows for a new level of privacy, and we encourage you to think of innovative use cases that emphasize the unique benefits that zero-knowledge unlocks. Some ideas include, but not limited to:\n\n- Privacy-preserving identity and credential management systems\n- Anonymous voting and governance platforms\n- Private data sharing and computation protocols\n- Privacy-enhancing communication and messaging applications\n- Privacy-focused decentralized storage and cloud computing solutions\n\n**General**\\\nSurprise us. If you have a cool idea and you don’t think it fits in any of the above tracks. Build it anyhow. The sky's the limit!\n\nGet inspired by our compilation of [past Scroll hackathon winners & submissions](https://github.com/dghelm/scroll-hackathon-builds/tree/update/projects_2023-11-15_00-06).\n\n# **Sponsor Partners**\n\n- **Ankr**\n- **Aztec**\n- **Chainlink**\n- **Covalent**\n- **Cyfrin**\n- **The Graph**\n- **OpenZepplin**\n- **Sindri**\n\n# **About Scroll**\n\nScroll is a zero-knowledge rollup built to scale Ethereum. We're committed to Ethereum's ethos, and like to call ourselves the community-first zkEVM.If you’re experienced in building on Ethereum, your code, dependencies, and tooling work with Scroll out of the box. This is possible because our network is compatible with EVM bytecode and designed to feel just like developing on Ethereum.\n\n# **Developer resources**\n\n- **[Developer Quickstart](https://guide.scroll.io/developers/developer-quickstart)**\n- **[Smart Contract Verification](https://guide.scroll.io/developers/verifying-smart-contracts)**\n- **[Developer Documentation](https://guide.scroll.io/developers/)**\n- **[Scroll Alpha Testnet Portal](https://scroll.io/alpha)**\n- **[Scroll Architecture](https://scroll.io/blog/architecture)**","onboardingCompleted":false,"registerFormUrl":null,"preRegisterTime":0,"publicContactHackerHandle":null,"hackersCount":792,"winnerAnnounced":true,"teamCount":0,"title":"V0RTEx 01 | A Scroll Hackathon","uname":"v0rtex-01","imageUrl":"https://cdn.dorahacks.io/static/files/18ecd7473042f58840879464102a841e.png","originUrl":null,"startTime":1713888000,"endTime":1714449540,"timezone":"240","city":null,"visible":true,"approvalStatus":6,"state":0,"voteUrl":null,"voteMechanism":null,"bonusPrice":85000,"bonusMechanism":null,"followersCount":0,"ecosystem":"ethereum, scroll","applyGuide":null,"weight":0,"participationForm":"Virtual","field":"Blockchain,Zero-knowledge,evm,DeFi,Gaming,privacy","email":"ayoung@scroll.io","contacts":"Email,ayoung@scroll.io","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":1,"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":1023,"name":"Noir prize pool","judgingCriteria":"","weight":0},"bountyObjs":[]}],"chain":[],"chainList":[],"appliedGrant":false,"acceptRewards":false,"owner":132353,"ownerInfo":{"nickname":"LorenzoTomaz","username":"lorenzotomaz","avatar":"https://cdn.dorahacks.io/static/files/18ebea847a225634d9f31144f33a97e2.jpeg"},"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":[],"infrastructureTags":[],"otherInfrastructures":["category:security"],"lastEditor":{"id":132353,"username":"lorenzotomaz","date":1736412698000},"upvoted":false,"followed":false,"upvoters":{"count":0,"list":[]},"kycStatus":0,"ideas":[],"name":"zkPaper","techniqueField":"","source":"-","vision":"zkPaper an anonymous document editor with proof of authorship and document sharing features","projectDescription":"zkPaper is a project that aims to bridge blockchain and security solutions for creating and editing private documents.
