ZM builders, we’re challenging you to hack with Polygon solutions to solve real-world problems. All prizes may be split by multiple teams!

🤝 $3,000 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.

🚀 $3,000 Best, most innovative hacks deployed on 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 startup worthy hack that's got a killer UX and is deployed to Polygon zkEVM. Deploying to Polygon zkEVM is as easy as changing your RPC url. 🚀

We've got infinite zkEVM build ideas ~ here are some other technologies and eips you could build on zkEVM

• 🤔 EIP 6551 on Polygon zkEVM, which gives every NFT a smart contract account, so NFTs could hold NFTs that could hold NFTs
• 🤔 Something data driven with a Subgraph from The Graph on Polygon zkEVM
• 🤔 Decentralized video hacks with Livepeer on Polygon zkEVM
• 🤔 Encrypt data before putting it on Polygon zkEVM for max privacy with Lit Protocol
• 🤔 Paymasters aka pay users' gas with Safe SDKs on Polygon zkEVM
• 🤔 Photo sharing with images pinned on IPFS in Polygon zkEVM NFTs

Bonus points if it's 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

🆔 $2,000 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.

Polygon ID resources:

• Polygon ID Dev Docs and tutorials

• How to run an Issuer to issue VCs: Video by Tony

• Fullstack VC-gated dapp template with everything you need for your KYCAgeCredential gated dapp by Steph

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.

🏊‍♂️ $2,000 Build #onPolygon in Public Pool Prize with valid Twitter post

Deploy your smart contract on Polygon (Polygon PoS Mainnet, Polygon PoS Mumbai Testnet, Polygon zkEVM Mainnet, or the Polygon zkEVM Testnet) and provide a link to the smart contract and your tweet. All teams that satisfy these requirements will split the pool prize.

Pool prize eligibility ✅

• In your project’s README link to your deployed smart contract(s) on Polygonscan
• Link to your tweet: Use this link to Tweet out the link to your Github repo and deployed smart contract.
