❌ $5,000 Best Cross-Chain Hacks with Polygon zkEVM

gm anon, or should we say ZM. We’ve officially entered the zkVerse with the launch of Polygon zkEVM Mainnet Beta. We’re challenging you to create a cross-chain or x-chain hack connecting Polygon zkEVM with Ethereum or Polygon PoS. Check out the universal bridge repo, a unified interface for sending messages from Ethereum to other chains and rollups to get started.

Cross-Chain ideas from the Polygon zkEVM team Implement an OpenZeppelin 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

May be split by multiple teams!

🆔 $5,000 Best use of Polygon ID's Verifiable Credentials

Self Sovereign Identity is the future. Use Polygon ID to represent identity-based information as verifiable credentials in your dapp so your users can prove access rights to dapp features without giving up their private data.

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.

🤝 $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 and Gasless transactions. **Account Abstraction SDKs **Safe{Core} Account Abstraction SDKs support Polygon PoS Mainnet and Polygon PoS Mumbai Testnet. Biconomy’s Gasless Transactions SDKs 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.
