VaultMask for ETHforAll'23

I am working on a project called VaultMask, which is based on Metamask Snaps. This project enables users to store, sync, share, and broadcast files of any type with ease. By utilizing a distributed file storage network, Filecoin, VaultMask provides secure and redundant file storage solution for users. However, users can also choose to keep their files private and local while also benefitting from reduced transaction fees by storing them with Snap. Additionally, once a file is stored on Snap, users can access it from any device.

To achieve this, we rely on the Push Protocol. When a user stores a file using Metamask Snap, a push notification is triggered, targeted only to the user. This notification contains the file's metadata (file name, CID, etc.) which can be accessed from any device that has the Metamask wallet associated with that specific user. Through push notifications, we not only notify the user about a file upload, but also help to synchronize files across all of the user's devices.
