How is this different from other storage?

Traditional cloud storage can access your files. With WalletBox, files are encrypted before they leave your device. The encryption key is derived from your wallet signature - never stored, never transmitted. Even we can't see your files.

Client-side encryption

Files are encrypted in your browser before upload. The server only stores encrypted blobs-never your data.

Frictionless sessions

Sign once with your wallet to create a 24-hour session. Upload and download freely without constant prompts.

Wallet-based identity

Your Solana wallet is your identity. No passwords to remember, no credentials to leak, no accounts to hack.

How it works

1

Connect your wallet

Connect with Phantom, Backpack, or Solflare. Your wallet becomes your login, no signup forms, no email verification. We only read your address - no transaction permissions.

2

Sign once

Sign a message with your wallet to derive a master encryption key. This key lives in your browser memory only, never persisted or sent to any server.

3

Upload and share

Files are encrypted in your browser with a unique key per file. Upload encrypted blobs to storage. Download and decrypt seamlessly, all automatic, all secure.
