\n\n# Polygon [$50,000]\n\n### **$20,000 🦄 The next up, STARTUP prize**\n\nWhat do [**Orb**](https://orb.ac/), [**Superfluid**](https://www.superfluid.finance/), and [**Push Protocol**](https://push.org/) have in common? All 3 of these major web3 projects started at hackathons. Polygon Labs is looking for killer apps and use cases (any type of project: infra / defi / social / privacy/app layer) built with Polygon technology. To qualify for this prize, build something useful with smart contracts on Polygon zkEVM, Polygon PoS or using Polygon ID VCs. Sell us on the use cases or problems your project solves and explain your business plan and the feature roadmap that you’ll continue to build after the hackathon on your path to becoming a startup.\n\n
\n\n### **$10,000 ↔️ Best cross chain dApp utilizing the Polygon zkEVM LxLy bridge**\n\ngm 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.\n\n**Cross-Chain ideas from the Polygon zkEVM team**\n\n- 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!\n- 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\n- Build a zkEVM NFT project with mint logic that depends on owning an asset on Ethereum or Polygon PoS.\n- 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)\n- Or even extend these repos to cover LxLy Bridging [https://github.com/ZeframLou/universal-bridge](https://github.com/ZeframLou/universal-bridge) or https://github.com/aave/governance-crosschain-bridges/tree/master/contracts/bridges\n\n
\n\n### **$10,000 👤 Best Use of Polygon ID for a privacy preserving dApp**\n\nSelf-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.\n\n**[This demo](https://github.com/docknetwork/polygonid-demo)** shows you how to set up your [**Dock.io**](http://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.\n\n
\n\n### **Polygon ID resources:**\n\n- [Polygon ID Dev Docs and tutorials](https://0xpolygonid.github.io/tutorials/)\n- How to run an Issuer to issue VCs: [Video](https://www.youtube.com/watch?v=19E-jLLRUO8&feature=youtu.be) by Tony\n- [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\n- This demo shows you how to set up your [Dock.io](http://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.\n\n**Ideas from the Polygon ID team:**\n\n- **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.\n- **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\n- **Bot protection** - Create a decentralized verification system providing individual VCs of liveliness & uniqueness that could be combined to prevent sybil attacks.\n- **VC gated Discord or telegram channels** - Create a way to gate a Discord channel or telegram chat based on a Polygon VC\n\n
\n\n### **$10,000 ⛽️ UX award for best dApp with Account Abstraction**\n\nBuild a dApp (public good, decentralized social media, dao tool, or any other type of project) on Polygon PoS or Polygon zkEVM with an app-like UX by sponsoring your users’ gas fees with a paymaster and / or bundling multiple transactions, for example approve and transfer, into a single transaction.\n\nIn your project’s README, explain the UX optimization strategies you chose and why. Link to relevant sections of code with your account abstraction implementation (paymaster or bundler).\n\nLearn more about AA by reading up on [ERC-4337: Account Abstraction](https://eips.ethereum.org/EIPS/eip-4337) and gasless transactions.\n\n
\n\n### **Account Abstraction SDKs:**\n\n- [Alchemy’s Account Abstraction SDK](https://docs.alchemy.com/reference/account-abstraction-sdk) supports Polygon PoS Mainnet, Polygon PoS Mumbai Testnet, Polygon zkEVM Mainnet, and Polygon zkEVM Testnet\n- [Biconomy’s Gasless Transactions SDKs](https://biconomy.gitbook.io/sdk/introduction/overview) support Polygon PoS Mumbai Testnet and Polygon zkEVM Testnet\n\n[Safe{Core} SDKs](https://docs.safe.global/learn/safe-core/safe-core-account-abstraction-sdk)\n\nsupport Polygon PoS Mumbai Testnet\n\n\n\n# Trust Wallet [$10,000]\n\n- **Visualization ($5,000)**\n\n - Support\n - Add visualization support for both [1inch fusion](https://github.com/trustwallet/wizard-sdk/issues/9) and [rarible](https://github.com/trustwallet/wizard-sdk/issues/8)\n\n - Community\n - create a registry smart contract that route to various [EIP-6865](https://github.com/ethereum/EIPs/pull/6865) implementation of different protocols\n - create a smart contract that is compliant with [EIP-6865](https://github.com/ethereum/EIPs/pull/6865) for 1inch fusion\n\n - Innovation\n - now as you are more familiar with wizard-sdk and the EIP-712 visualization concept, propose the best way to solve this widespread issue (it can be one of the 2 already existing ones, the SDK or on-chain visualization EIP, just make sure to defend your idea)\n\n- **Simulation ($5,000)**\n\n - Support\n - add more debug node providers factories, at least Alchemy and Tenderly\n\n - Security\n - extract slippage AMM calls (uniswap, 1inch,..etc), calculate the min amount and add it to amounts array, note that you can’t rely on the calldata only as someone can use a bundler to bundle multiple transaction (use the simulation internal calls to identify the AMM call, decode it and extract the slippage/minOut)\n\n - Innovation\n - Currently, slippage is a significant issue in decentralized finance (DeFi) because each protocol uses a different data format. It is challenging and not scalable to add custom implementations for each protocol, decode the data, and extract the slippage value.\n\nTo address this problem, a scalable solution is needed that would allow wallets to protect users from miner-extractable value (MEV) attacks targeting transactions with unset slippage (or set to 100%). One potential solution is to create an Ethereum Improvement Proposal (EIP) that standardizes the way slippage is encoded and decoded across all DeFi protocols. This would enable wallets to easily extract the slippage value from any transaction data and alert users if the slippage is unset or set to 100%, providing an additional layer of protection against MEV attacks. Alternative implementations that achieve the same goal are also worth considering.\n\n# Circle [$10,000]\n\n**Total bounty size : 10K**\n\n**Build the Best Use Case for Circle’s Programmable Wallets**\n\n**About Programmable Wallets**\n\nProgrammable Wallets enable developers to create and embed secure Web3 wallets at scale in minutes.

Here is the user story. User when entering the app, logs in with his gmail account for seamless web2-like onboarding. After onboarding, user can choose to purchase USDC or EURC using CirlceMint feature. Users can invite his colleagues or friends to connect or join a shared expense group. The users in the group can add their crypto expenses in USDC, EURC or any crypto on all chains that are supported by Circle. Users can settle the expenses of different cryptos using a single currency. CircleCut smart contract powered by Phala Network will be used to fetch price conversion real time when the user is settling his expenses. The user first calls the “getSettlement” function to get the realtime price conversion for all the currencies he need to settle with the currency he chooses to settle with. For example, if he settles with USDC and he owes EURC, ETH, MATIC to 5 different users. He gets the total amount to be paid on-chain using the Phala Network Oracle so that the price conversion is verified and transparent. And then he calls the “settle” function with the amount of USDC he owes. This sends out the respective value of USDC each person is owed in the same chain. If the user wishes to transfer the USDC or EURC from one chain to another, he can do it seamlessly in the app using the Cross-chain swaps feature provided by CircleCCTP. User can also withdraw and deposit funds anytime from and to anyone’s wallet.\n\n# Flow Diagram ⚙️\n\n![circlecut-bg.png](https://cdn.dorahacks.io/static/files/18bfdc81e8f65948ed94d8e48f4a20e4.png)\n\n# Bottom Line\n\nWe have well documented our development process from the Day 1 of the hackathon constantly staying in touch with the development team, attending technical workshops in the Circle Discord Channel.
