🔀 Cross-chain / LxLy Bridge implementation ⸺ $5,000

Up to 2 teams will receive $2,500

gm anon, 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 and open a PR with your own contribution that facilities cross-chain communication.

Qualification Requirements

- Display links to both versions of smart contracts deployed on Goerli/Ethereum and zkEVM Testnet / zkEVM Mainnet in your README - Submit transactions of cross-chain communications from L1 to the zkEVM rollup and/or vice versa in your README 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! - 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 Universal Bridge

🆔 Best use of Polygon ID to preserve user privacy ⸺ $2,500

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 is also excited to announce a brand new partnership with 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 in 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.

Qualification Requirements

Build a full stack dApp that utilizes Polygon ID to issue decentralized identifiers and verifiable credentials. Your application should cover the full lifecycle of verifiable credentials, issuance, holding using the Polygon ID wallet and verification from your dApp.
