Because it is a part of MetaMask, it can be easily integrated into any dapp that already supports MetaMask using our [**SDK**](https://docs.masca.io/docs/libraries/masca-connector). Masca follows the latest advancements in the decentralized identity sphere - thus, it builds upon W3C standards DID (Decentralized Identifier) and VC (Verifiable Credentials) and integrates various protocols such as Ceramic Network, Polygon ID, and OpenID Connect (OIDC). \n\nThe code is [**open-sourced**](https://github.com/blockchain-lab-um/masca), and Masca has been live on the official [**MetaMask Snaps registry**](https://snaps.metamask.io/) since day 1.\n\nMasca also comes with a [**dapp**](https://masca.io/) that provides users an easy-to-use dashboard for managing their credentials and configuring their wallets for their needs.\n\n## Problems it solves\n\n- It provides millions of MetaMask and Web3 users **easy access to decentralized identity**.\n- Masca **delegates handling of the cryptographic keys to the MetaMask**, one of the most used and secure Web3 wallets. Keys can also be backed up with a seed phrase.\n- Users can decide (if they want) which DID method to use and where to store their VCs (e.g., more private locally and public ones on Ceramic Network).\n- You can create as many DIDs as you want! It is as simple as making a new blockchain account in MetaMask.\n- **Easy integration of DIDs and VCs** into any dapp using **[the Masca Connector](https://docs.masca.io/docs/libraries/masca-connector)** library. No need to reimplement all custom logic for multiple DID methods and VC storage solutions.\n- dapps communicate with Masca in the same way as MetaMask through simple RPC calls/methods. This includes requesting DID identifiers and VCs and creating VPs (Verifiable Presentations).\n- **All decentralized identity functionalities supported**: creating VCs and VPs, managing DIDs, verifying and validating VCs and VPs, and resolving DIDs.\n\n## Features\n\n- Management of DIDs defined by different DID methods (did:pkh, did:key, did:polygonid, did:ebsi …).\n- Creating, storing (locally or on Ceramic Network), and verifying VCs and VPs.\n- Create zero-knowledge proofs (ZKPs) or selectively disclose your data to improve privacy.\n- Receiving issued VCs and sharing credentials/presentations over various identity and data exchange protocols, such as OpenID Connect (OIDC) and Polygon ID.\n- Support for mutlitple digital signature formats - JSON-LD, EIP712, JWT, JWZ.\n- Leveraging the security of the battle-tested MetaMask wallet.\n- Masca had a security audit performed in September 2023 by [Least Authority](https://leastauthority.com/blog/audits/audit-of-masca-metamask-snap/).\n\n## Architecture\n\nMasca dapp:\n![Untitled](https://i.imgur.com/dM775n7.png)\n\nMasca diagram:\n![image.png](https://i.imgur.com/VRC6yFS.png)\n\n## Integrations\n\nSupported blockchains - Ethereum, Polygon, Optimism, and Arbitrum\n\n[Polygon ID](https://www.polygonid.com/)\n\n[Ceramic Network](https://ceramic.network/)\n\n[EBSI](https://ec.europa.eu/digital-building-blocks/sites/display/EBSI/Home)\n\n## Roadmap\n\nYou can find the roadmap for Masca on the [documentation page](https://docs.masca.io/docs/roadmap).\n\n## Links\n\n[Masca website](https://masca.io/)\n\n[Masca documentation](https://docs.masca.io/)\n\n[Masca Twitter](https://twitter.com/masca_io)\n\n[Masca GitHub](https://github.com/blockchain-lab-um/masca)\n\n[Blog](https://medium.com/@blockchainlabum)\n\n[MetaMask Snaps Directory Page](https://snaps.metamask.io/snap/npm/blockchain-lab-um/masca/)\n\n[Lutra Labs website](https://lutralabs.io/)", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "blockchain-lab-um", "projectTwitter": "masca_io"}
