ZM builders, we’re challenging you to hack with Polygon solutions to solve real-world problems. ### **🔀 $5,000 Best use of zkEVM** The Polygon zkEVM launched earlier this year, it's grown to hold a TVL of $50 million and continues to attract major protocols. For this challenge, we want to see your most innovative use of the Polygon zkEVM, this is an open challenge that will see the most innovative and deserving protocols, with killer UX carry the day! Check out these resources to get you started. * [Documentation](https://zkevm.polygon.technology/docs/develop) * [Full Stack dApp demo](https://zkevm.polygon.technology/docs/develop) ### **❌ $5,000 LxLy Bridge zkEVM Extension** gm anon, or should we say ZM. At the heart of Polygon’s new 2.0 architecture lies the LxLy bridge. The Polygon zkEVM LxLy Bridge facilitates cross-chain communication across Polygon chains. We’re challenging you to create and extend the LxLy sample implementations and add support for different types of cross-chain messaging and assets transfer of custom ERC-20s and any other EIP/ERC you see fit such as ERC1155 etc. Check out the existing [code samples](https://github.com/0xPolygonHermez/code-examples) and open a PR with your own contribution that facilities cross-chain communication. **Cross-Chain ideas from the Polygon zkEVM team** * Claim UI: Build a Dapp to allow users to connect and see all valid messages they have that are claimable on a given LxLy chain (Polygon zkEVM etc) and claim them! * Implement an [OpenZeppelin Governor](https://docs.openzeppelin.com/contracts/4.x/governance#governor) that allows token holders to vote on Polygon zkEVM with proposals that are still on Ethereum or Polygon PoS Create a snapshot strategy that accounts for token balance on Ethereum, Polygon PoS, & Polygon zkEVM * Build a zkEVM NFT project with mint logic that depends on owning an asset on Ethereum or Polygon PoS * Permissionless Prover: A smart contract that allows Polygon Labs to put up a reward for anyone who fills in as permissionless prover for when our infra goes down essentially a contract that has a function that checks whether a given verifyBatches() call was successfully called by anyone other than our trusted address, and if so, pays out some fixed reward it holds (MATIC tokens) * Or even extend these repos to cover LxLy Bridging https://github.com/ZeframLou/universal-bridge or <https://github.com/aave/governance-crosschain-bridges/tree/master/contracts/bridges> ### ### **🆔 $5000 Best use of Polygon ID's Verifiable Credentials to preserve user privacy** Self-Sovereign Identity is the future. Use Polygon ID to represent identity-based information as [verifiable credentials](https://0xpolygonid.github.io/tutorials/#core-concepts-of-polygon-id-verifiable-credentials-identity-holder-issuer-and-verifier-triangle-of-trust) in your dapp so your users can prove access rights to dapp features without giving up their private data. Polygon ID is also excited to announce a brand new partnership with [Dock.io](http://Dock.io) that will allow you to securely extend the privacy of your Lens profile using Verifiable Credentials. Using Dock's REST API credentials can be issued a few API calls. Along with issuing credentials application developers can use the API to manage issuer profiles and create and import data schemas. Dock's tooling also supports non-developers through it's no-code solution Dock Certs which provides the same functionality via a web interface. [This demo](https://github.com/docknetwork/polygonid-demo) shows you how to set up your Dock.io account and begin to issue VCs. Your task is to now leverage VCs to provide additional layers of privacy and security to your Lens Dapp. **Polygon ID resources:** * [Polygon ID Dev Docs and tutorials](https://0xpolygonid.github.io/tutorials/) * How to run an Issuer to issue VCs: [Video](https://www.youtube.com/watch?v=19E-jLLRUO8\&feature=youtu.be) by Tony * [Fullstack VC-gated dapp template](https://github.com/oceans404/fullstack-polygon-id-vc-gated-dapp/tree/main) with everything you need for your KYCAgeCredential gated dapp by Steph * This demo shows you how to set up your Dock.io account and begin to issue VCs. Your task is to now leverage VCs to provide additional layers of privacy and security to your Lens Dapp. **Ideas from the Polygon ID team:** * **Anonymous voting** - On-chain voting exposes the choices made by different public addresses. Create a hack that proves DAO membership with a VC while making sure members don’t double vote. * **Social proof of influence or activity** - Create a proof of influence issuer that issues VCs based on numbers of followers or number of posts across social platforms * **Bot protection** - Create a decentralized verification system providing individual VCs of liveliness & uniqueness that could be combined to prevent sybil attacks. **Lens Ideas:** * **KYC:** Imagine if you can securely add KYC to your Lens dapp and be able to rely on the authenticity of that data * “**Lenster badges” from Polygon ID credentials:** Import a Polygon ID credential and create a [Lenster badge](https://www.notion.so/Lenster-badge-5bf35b1a253c4c2c9231932908c21658?pvs=21) from it (Proof of Hacker, Proof of Human, Polygon Activist,). You could combine these with any of the credentials from WIW or any of the [free credential issuers that use Polygon ID](https://www.notion.so/Polygon-ID-Public-Credentials-Issuers-98a1a0d8ae19414ca160e84506b357d6?pvs=21). [Lenster badge](https://www.notion.so/Lenster-badge-5bf35b1a253c4c2c9231932908c21658?pvs=21) ### **🤝** $5,000 Best Public Good with Account Abstraction or Gasless transactions on Polygon Create a permissionless public good dapp with an app-like UX by sponsoring your users’ gas fees using gasless transactions or by batching transactions into a single transaction. Learn more by reading up on [ERC-4337: Account Abstraction](https://eips.ethereum.org/EIPS/eip-4337) and Gasless transactions. **Account Abstraction SDKs** * [Safe{Core} Account Abstraction SDKs](https://docs.safe.global/learn/safe-core/safe-core-account-abstraction-sdk) support Polygon PoS Mainnet and Polygon PoS Mumbai Testnet. * Biconomy’s [Gasless Transactions SDKs](https://biconomy.gitbook.io/sdk/introduction/overview) support Polygon PoS Mumbai Testnet with Mainnet and zkEVM networks coming soon. In your project’s README, explain the UX optimization strategies you chose and link to relevant sections of code with your account abstraction implementation.

**1. Main Bounty: Total of 9,400 USD** **Best Use of RelationService - Develop the Next-Gen Application with a Portable Universal Profile** **Prize Pool** 1st prize (max 1): $3k USD 2nd prize (max 2): $2k USD 3rd prize (max 3): $800 USD **Description** Utilize the RelationService API (**https://docs.next.id/relation-service/rs-graphql**) to develop a use case that addresses market needs. Strive to be as innovative as possible. **Recommended Use Cases (but not limited to):** **Cross-Platform Profile Search and Recommendations** Get an understanding of what this involves and why it's useful by visiting [**web3.bio**](http://web3.bio/) first. For instance, consider linking a Twitter account with Mastodon using a DID. **Sybil Attack Resistance by Wallet History Verification** For instance, in a significant airdrop event, bot accounts controlled by a small group of people need to be filtered out, ensuring that each user claiming the airdrop is a legitimate individual user. **DAO (Decentralized Autonomous Organizations) Tooling** For instance, a DAO member's credentials can be made portable across different blockchain ecosystems. For instance, when a new member joins, their existing social credentials can be immediately displayed, and different access levels can be provided based on their existing profile data. **Growth and Personalization** For instance, utilize a universal profile(Similar to this one: https://web3.bio/vitalik.eth) to identify potential user personas. Track social identities using wallet addresses and use this information to create look-alike audiences. For instance, use a universal profile(Similar to this one: https://web3.bio/vitalik.eth) to solve the cold-start problem for apps. Allow users to invite their connections on Web2 by examining the wallet addresses they interact with. **Acceptance Criteria** **Proof of Work**: Submit either an open-source project published on GitHub for the judges to review, or if its business value necessitates confidentiality, share a private project repo address with us. **Relevance**: Your use case should be pertinent and demonstrate a practical application of the RelationService feature within the DID protocol. **Protocol Compliance**: Your use case must fully adhere to the DID protocol's specifications and accurately implement the RelationService feature. **Security**: Your use case must prioritize data privacy and security. It should not introduce any security vulnerabilities. **Innovation**: Creative or innovative applications of the RelationService feature are highly valued, even though not strictly required. **License Compliance**: All submissions must be in accordance with the licensing terms of the open-source project. **2. Side Bounty: 600 USD** **ProofService: Continue validation API** **Description** ProofService is a zero-trust identity relationship creation/query protocol. We have a reference implementation called [proof\_server](https://github.com/nextdotid/proof_server). The binding relationship between a web2 identity and ProofService's web3 identity (named `Avatar`) is done through cryptography signing and "Proof Post" mechanism. Currently, if a user encounters a problem (e.g., client crashed / closed) submitting their proof post to the NextID server after posting it on target platform, NextID's process doesn’t allow the user to continue the process from this proof post with zero additional info. We would like to add an API to allow users to restart the verification process from an existing proof post, without other info fetched from `POST /v1/proof/payload`. From now, all info needed for restart validation procedure is included in the proof post itself (incl. signature, UUID, `created_at` timestamp, previous proof’s signature). You need to create an API except only the proof post’s location, and recover the “site” only from proof post’s content, then continue validation and saving procedure just like a normal one. **Acceptance Criteria** An API (named by you), request with proof post’s location, platform and identity, response like [POST /v1/proof](https://docs.next.id/rest-api/proofservice-api#proof-add) . Modify `type IValidator interface` , add a new function: `Continue() (err error)` for your core logic. You can always use your own code structure design if you feel something is wrong. Only one `platform` implemented is OK. Starting with `validator/twitter` is recommended. Write test for your `Continue()` function and API. **Winner setting** Will accept only 1 winner, judged by code quality and function completeness The sole winner will be rewarded with 600 USD

💰 **$2500 - most useful onboarding site for Flashbots Protect with MEV-Share** Flashbots Protect aims to be the best place to send transactions on Ethereum. It’s a transaction service that offers frontrunning protection, transaction reverts protection, configurable privacy and execution, and the ability to internalize MEV for everyday users when sending transactions on Ethereum, as simple as adding the Flashbots Protect RPC to their wallets. Since its inception in Oct 2021, Flashbots Protect RPC had protected thousands of Ethereum users from the [dark forest](https://www.paradigm.xyz/2020/08/ethereum-is-a-dark-forest). Earlier this year, Flashbots Protect went through a major upgrade via [MEV-Share beta](https://collective.flashbots.net/t/announcing-mev-share-beta/1650), which provides [configurable privacy](https://docs.flashbots.net/flashbots-protect/rpc/mev-share) and the ability for users to receive MEV refunds for the MEV they created in sending transactions. Last week, Flashbots Protect is [turbocharged with a 4x speed improvement](https://twitter.com/hasufl/status/1679152469518045186) - users can opt-in to share their transactions with additional block builders that account for 80% of the market. However, most resources on Flashbots Protect and MEV-Share are dense with information and difficult to digest for everyday users who could have benefited from using Flashbots Protect. Build a creative and intuitive onboarding site for Flashbots Protect. **Some elements you can incorporate on the website** * A tool that shows the user the history of the wallet address’ interactions with Flashbots Protect * Statuses of user's Protected txs * User's MEV-Share refund total **Submission requirements** * A functional and complete onboarding site * The website must have a one click button to use Flashbots Protect as RPC for the user’s wallet. * The code should be open sourced **Nice to haves for bonus points** * A viral marketing hack **Judging criteria** * Creativity and innovation in the project idea and implementation * User experience and ease of use * Compliance with submission requirements and guidelines * Open source availability of the project code **Resources** * [MEV Blocker](https://mevblocker.io/)’s official website is a good reference * Docs page for [Flashbots Protect](https://docs.flashbots.net/flashbots-protect/overview) and [MEV Share](https://docs.flashbots.net/flashbots-mev-share/overview) * Flashbots Protect’s [public beta announcement](https://writings.flashbots.net/announcing-protect) and [one year review at Merge](https://writings.flashbots.net/flashbots-protect-merge-and-beyond) * Bert’s post on the [design of MEV Share](https://collective.flashbots.net/t/mev-share-programmably-private-orderflow-to-share-mev-with-users/1264) and [announcement of MEV Share beta](https://collective.flashbots.net/t/announcing-mev-share-beta/1650) * Fastlane’s awesome [Searcher Explorer App](https://twitter.com/0xPFL/status/1666768931082715138) 💸 **$1500 - building the coolest bot searching on MEV-Share** MEV-share presents searchers with a new challenge of competing for and executing against transactions of users with configurable privacy. We want to see what kind of cool bots you can build with such transactions! **Submission requirements** * A functional bot that can search on MEV-Share * Present the bot to other hackers without code **Nice to haves for bonus points** * Make the bot open sourced and continue running it after hackathon **Judging criteria** * Creativity and innovation in both the project idea and its implementation * Effective utilization of MEV-Share's new order type and programmable privacy features * Adherence to all submission requirements and guidelines * Availability of the project code as open source **Resources** * Same resource from the previous challenges * [Protocol specs](https://github.com/flashbots/mev-share) * [Node implementation](https://github.com/flashbots/mev-share-node) * [Typescript client library](https://github.com/flashbots/matchmaker-ts) * [Simple blind arbitrage bot repo](https://github.com/flashbots/simple-blind-arbitrage) * Limit Order Bot [tutorial](https://docs.flashbots.net/flashbots-mev-share/searchers/tutorials/limit-order/introduction) and [repo](https://github.com/flashbots/simple-limit-order-bot). Very beginner friendly! Check out [Shea’s twitter thread](https://twitter.com/sheaketsdever/status/1679872463520366592) for even more context. **🏆 $1000 - best design for using MEV-Share and programmable privacy in another application** The [programmable privacy](https://collective.flashbots.net/t/mev-share-programmably-private-orderflow-to-share-mev-with-users/1264) design in MEV-Share presents a new paradigm that allows users to programmatically share information with searchers to bargain for the MEV they create in a permissionless fashion. This also creates the challenge of how to best program the privacy for different use cases. We would like to invite you to brainstorm how to leverage programmable privacy in applications like NFT, oracle updates, DEXe… **Candidate ideas** * New default [hint configuration](https://docs.flashbots.net/flashbots-protect/rpc/mev-share) for a certain use case like NFTs * A specification for using MEV-Share in a dapp **Submission requirements** * A functional and complete design for using MEV-Share and programmable privacy in another application * The design must be detailed and explain how it will work in practice * The solution should be novel and innovative * The code should be open sourced **Judging criteria** * Novelty and innovation of the design * Feasibility and practicality of the design * Compliance with submission requirements and guidelines * Open source availability of the project code **Resources** * Same resource from the previous challenges * [Programmable privacy specs](https://collective.flashbots.net/t/mev-share-programmably-private-orderflow-to-share-mev-with-users/1264) * [Docs page for MEV Share](https://docs.flashbots.net/flashbots-mev-share/overview) * [Flashbots Protect RPC docs](https://docs.flashbots.net/flashbots-protect/rpc/mev-share)

## $1500 Wildcard: Best use of Lit Protocol ## $3500 Best Use of Lit Actions and Programmable Key Pairs Utilize programmatic signing in a novel way. We're looking for creative uses of programmatic signing that enhance web3 usability. That might look like abstracting away signing from an end user or automating signing based on different conditions. Some ideas: * ActivityPub integration with PKPs * Unity x PKPs * web3 private social, powered by Lit Actions

**Bounty #1: 🛠 Use Aragon OSx to solve a problem in your local community \[$2,500]** **👀 Description** * Like many other projects in the ecosystem, Aragon came out of the need to solve some of the world's largest issues. * Corruption, climate change, terrorism - these are threats the world must solve together. And yet building together often requires trust among strangers and can lead to centralization of power. * To solve this, Aragon OSx is a DAO framework, enabling communities to manage their assets in a decentralized and trustless way. * Through its modular architecture, organizations can easily install and uninstall plugins into their DAOs, enabling greater transparency and equity within communities. * Through this prize, we want to see teams use crypto to solve a pressing issue within your communities - be it the oversight of a property or public good (like a park or a school), the incentive of certain collective behaviors (like using tokens for rewards and voting power), the management of assets for a specific mission, or any other idea that comes to mind! * Whether you decide to build your own plugin, dApp or custom DAO - we’re looking for fun, creative projects who want to leverage the power of on-chain governance to solve a problem in their local community and make the world a better place. **✅ Requirements** * a) Must be a solution to a local problem or need (wherever local is to you) - i.e. park management, neighborhood elections, university clubs, etc. * b) Submission can be a dApp, an Aragon OSx plugin, or any other prototype. * c) Submission needs to leverage Aragon in some way ([App](https://app.aragon.org/), [OSx](https://github.com/aragon/osx), CLI, [SDK](https://github.com/aragon/sdk)). * d) Must submit a project description, a pitch including a demo, a Github repository with a README on how to run the project, as well as a working prototype. * e) Bonus points for creativity and innovation! **👩🏽‍⚖️ Judging Criteria** * a) Having an innovative solution to a local problem * b) Understanding and usage of Aragon OSx * c) Meeting of the requirements * d) Bonus points for a user-friendly UX and good docs **Bounty #2: 💰Build a plugin that helps DAOs raise funds \[$2,500]** **👀 Description** During the last bull run, DAOs proved to be a great mechanism for raising funds. Projects like ConstitutionDAO, for example, were able to show the world how raising funds in crypto could lead to “real-world” actions and impact. Some examples of characteristics that have made this possible: * a) DAO tokens added to liquidity pools. This enables DAO tokens to be instantly exchanged with other assets, granting them liquidity and value. * b) [Bonding curves](https://outlierventures.io/bonding-curves-and-a-prelude-to-sptokens/) as a way of ossifying the relationship between token price and supply. * c) Rage quit functionality, meaning a person can leave the DAO and take a representative share of the treasury’s value based on how many DAO tokens they own. * d) Among other non-technical characteristics like good marketing, relatable mission, good roadmap, trusted team, etc.. With this bounty, we want to see an [Aragon OSx Plugin](https://aragon.org/how-to/build-a-dao-plugin-using-aragon-osx) that enables DAOs to raise funds easily - be it through facilitating any of the above mentioned examples, or through crafting your own strategy! All ideas are valid. **✅ Requirements** * a) The submission should facilitate Aragon DAOs to raise funds * b) The submission should leverage Aragon OSx * c) The submission should be at least deployed to a testnet chain * d) Submission should include a demo and documentation on how to get the project up and running locally **👩🏽‍⚖️ Judging Criteria** * a) Effectiveness of the solution to raise funds for DAOs. * b) Understanding and usage of Aragon OSx * c) Meeting of the requirements. * d) Bonus points for a user-friendly UX and great docs. **📚Resources** * a) [Liquidity pools](https://mixbytes.io/blog/how-to-add-new-pool-uniswap-v3) * b) [Bonding curves](https://outlierventures.io/bonding-curves-and-a-prelude-to-sptokens/) * c) [Rage quit](https://coinmarketcap.com/alexandria/glossary/rage-quit) * d) [DAO Legal Frameworks](https://mirror.xyz/fortunata.eth/hZOOn5rrQ3Kyq81iSEKXjUJmN281PBOgJByIn9dveU8)
