ZM builders, we’re challenging you to hack with Polygon solutions to solve real-world problems. ### **🔀 $2,500 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) \======================================== ### **❌ $2,500 LxLy Bridge zkEVM Extension** 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> \======================================== ### **🆔 $2,500 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) \======================================== ### **🤝** $2,500 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.

**🥇Top prize - $3,000 - Best Use of Hyperlane** The grand prize will be given to the most compelling submission made during the hackathon. It can qualify under any of the categories below, so be sure to read them to get some ideas! Think of the grand prize as an extension of the category prizes. **🎼 $2,000 1st, $1,000 2nd - Best Interchain Applications** An interchain application is an application that communicates between different blockchains. It can either transfer assets or make interchain function calls. The winner of this prize will be the most impressive application that makes use of Hyperlane and benefits from its presence on multiple blockchains. Depending on the quality of submissions relative to other categories, Hyperlane may award several Interchain applications. **💸 $2,000 - Best use of Hyperlane Warp Routes** Warp Routes are Hyperlane’s unique take on token bridging. They are unique and instanced expression of bridging as opposed to the traditional omnibus token bridge design. Each Warp Route can have its own security model, using Hyperlane’s Interchain Security Modules. Perhaps most importantly, Warp Routes are completely permissionless! No one can stop you from bringing whichever asset you’d like to any chain you’d like. To win this prize, you need to use Warp Routes in your submission. However, the more creative your submission is, the better. **🚝 $2000 - Best Hyperlane Infrastructure** This category is for building infrastructure that either enhances Hyperlane or makes use of Hyperlane's capabilities. Maybe you’ll build a customized Deploy tool to bundle Hyperlane with any OP Chain deployment? Or perhaps you’d build a way to more easily connect chains with Hyperlane? Maybe you’ll build a tool to allow any chain to get access to oracle feeds from any chain? You decide! To win, your submission will have to serve a useful purpose either for Hyperlane users, or utilize Hyperlane to provide a valuable service to someone else. **🌐 $2,000 - Write new Interchain Security Modules (ISMs)** Hyperlane’s Modular Security Stack is based on a range of Interchain Security Modules that developers can use to secure the way applications communicate between chains. Some ISMs are already available, and more are being developed. The hackathon is a great chance to build new ones.

The gating can include, but is not limited to, the following 🔽 **Token Gated Group**: Implement a rule that only allows users who hold XX number of a specific token to join the group **NFT Gated Group**: Allow only users who hold a specific NFT to join the group **Multi-Chain Conditions**: Enable users to join the group if they meet token holding requirements on either Ethereum or Polygon **Message Sending Conditions**: Implement a rule that allows users to join a group with 1 token but requires 100 tokens to send a message within that group **Non-Web3 Conditions using Guild**: Implement a rule where users must follow @pushprotocol on Twitter to join the group **Game Theories with Multiple Conditions**: Create complex gating rules that combine one or more of the above conditions. For instance, a user needs 1 token on any chain to join but must hold 1000 tokens, or 1 NFT, or 20 POAPs to send messages.
