ODD SDK
An SDK for building apps with decentralized identity and storage
...Your users’ data is kept secure by default by the ODD SDK's encrypted-at-rest file storage protocol. Users have control over who has access to their private data thanks to the Privacy and Encryption features of the ODD Filesystem. ODD apps are local-first and include the ability to work offline and collaborate across multiple devices, while also improving the security, privacy, long-term preservation, and user control of data.
