Could you build this?
Partial The file-sharing UI, upload flow, and Stellar payment and notarization hooks are vibe-codeable, but getting client-side encryption, key management, and access control right is security-critical work that needs expert review.
What it would actually take: Use a client-side encryption layer (for example, AES-GCM with keys derived from the user's wallet or passphrase), an object store such as S3 or IPFS for ciphertext, and the Stellar SDK for payments and hashing file digests onto the ledger. The hard parts are key management, safe sharing without exposing keys to the server, and a cryptography review. This needs security engineering experience and an audit before real users rely on it.
