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](https://www.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.

Qualifications

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.

The Polygon zkEVM launched earlier this year and it has 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!

Qualifications

Be Innovative Deploy to the zkEVM Note: You can deploy to Mumbai if you're project requires another service provider that's not supported on the Polygon zkEVM

With the launch of the Polygon zkEVM, brand new rails were established that allow DeFi developers to get started with deploying on L2s. In this challenge, we are inviting participants to deploy a General DeFi application of any category to the Polygon zkEVM Testnet.

Qualifications

The requirements are dead simple: - Develop a DeFi application. - Deploy the application on Polygon zkEVM Testnet / Mainnet - Integrate an OpenZeppelin library

We know that building a dApp that queries blockchain data can be cumbersome. With the Chain Indexer Framework you can unlock the true potential of EVM blockchains by seamlessly integrating them into your data infrastructure. Whether you are building real-time analytics, decentralised applications, or any other data-driven solution, this framework assists you in developing robust and efficient event-driven data pipelines on EVM blockchains.***Some Sample Use-Cases:*** **Wallet Services**: Blockchain indexers can help wallet providers offer more features like transaction history, balance history, and real-time updates. **dApp Backend**: dApps often require real-time access to contract events, token transactions, and other on-chain activities. A data indexer can speed up this process considerably. **Analytics and Monitoring**: Firms specialising in blockchain analytics use indexers to monitor activities like fraudulent transactions, smart contract interactions, and trends in token transfers. **Cross-Chain Services**: For cross-chain swaps or interactions, indexers can offer data that facilitates more seamless integrations. **Oracles**: Data indexers can support oracles by providing them with a more efficient way to access specific data points on the blockchain. **NFT Marketplaces**: To track ownership changes, price histories, and various attributes of NFTs, data indexers are often used in the backend.

Qualifications

Deploy the Chain Indexer Framework and integrate it to a smart contract on Polygon zkEVM and provide links to your deployment and your deployed smart contract addresses.

The dApp Launchpad is a dApp and smart contract development tool tailored for the Polygon blockchain networks.
