WalletBox

$WB403

WalletBox is a non-custodial, end-to-end encrypted file storage app for Solana users. Files are encrypted before they leave the device; decryption keys are derived from the user’s wallet signature and are never stored on WalletBox servers. The app uses OpenKitx403 wallet authentication so users can connect read-only (no transaction permissions required) and access encrypted content without passwords or accounts. Builders can integrate WalletBox’s approach in their own apps to provide wallet-bound storage and secure file sharing. WalletBox focuses on privacy by design, simple UX, and open-source components that can be verified and self-hosted by teams that need stronger guarantees.
