Built on OpenKitx403 wallet authentication
Your files.
Your control.
Store files with true end-to-end encryption. Only your Solana wallet can decrypt them. No servers. No passwords. No trust required.
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
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.
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.
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.
