Please view the third-party content disclaimer [here](https://github.com/0xPolygon/polygon-docs/blob/main/CONTENT_DISCLAIMER.md). [Crust Network](https://crust.network) is a decentralized storage network that supports IPFS and provides onchain storage functions. It works across multiple smart contract platforms, including Polygon, via a cross-chain solution. Crust matches users who need storage with network participants who have available disk space. Files are stored via IPFS and persisted using Crust's decentralized storage market. For background on how Crust's storage mechanisms work, see: * [Decentralized Storage Market](https://wiki.crust.network/docs/en/DSM) * [Cross-chain Storage Solution](https://wiki.crust.network/docs/en/buildCrossChainSolution#ii-native-ipfs-integration) * [Crust Build-101](https://wiki.crust.network/docs/en/build101) ## Storage helper tools Use these tools to upload and pin content to IPFS with Crust: * [Crust Files](https://crustfiles.io): A personal cloud storage interface for Web3 that supports multi-wallet login and fully decentralized storage. * [IPFS W3Auth Gateway](https://docs.ipfs.tech/concepts/ipfs-gateway/#authenticated-gateways): A Web3-authenticated IPFS gateway supporting all IPFS write operations. Upload files or host content after completing W3Auth verification. * [IPFS W3Auth Pinning Service](https://wiki.crust.network/docs/en/buildIPFSW3AuthPin): A standard IPFS pinning service with Web3 authentication. Access Crust storage without interacting directly with the Crust blockchain. * [Crust GitHub Action](https://github.com/marketplace/actions/crust-ipfs-pin): A GitHub Action for decentralized CI/CD hosting via Crust IPFS pinning.
