Show HN: Lockbridge-Secure File Transfers with Multi-Cloud Support&Audit Trails

1 points by audreymplatta1 9 hours ago

Hi! I built Lockbridge because encrypted file sharing and management are still too complicated in 2025.

Core features: - Bridges – shareable links for encrypted uploads/downloads with auto-expiration - Cloud federation – unified dashboard for S3, Azure, GCP, Google Drive, Dropbox and more… - Blockchain audit trails – immutable compliance logs on Polygon for HIPAA/SOX (optional) - Zero-knowledge encryption – client side end-to-end encryption, we can't decrypt your files

Example use case: Create a bridge, send the link to a client, they upload files directly to your Google Drive/S3/Dropbox. Bridge expires after 24 hours (could be 1 week or 1 months depending on user input). For regulated industries, every transfer gets logged to the blockchain with a Polygon Scan receipt.

We're currently in beta looking for feedback on the bridge UX, cloud federation interface,and whether blockchain compliance is useful beyond regulated industries.

All feedback is welcome!
