Wallet2QR

Honey-encrypted QR backup for your seed phrase

Encrypt your BIP-39 mnemonic into a QR code protected by honey encryption. Every password produces a valid mnemonic — attackers can never tell which one is real.

Honey Encryption

Every password produces a valid mnemonic. Attackers who steal your QR cannot brute-force the correct one — they drown in plausible decoys.

Client-Side Only

Encryption and decryption run entirely in your browser using WebAssembly (Argon2id). Nothing is sent to any server.

QR + File Backup

Save your encrypted backup as a QR code (PNG/SVG) or payload file (JSON/text). Restore your mnemonic anytime.

Use as a Virtual Hardware Wallet

Your encrypted QR can also serve as an external signer for crypto wallets — like a Ledger or Trezor, but without the USB device. Scan the QR, enter your password, and sign transactions.

Nothing Stored

No mnemonic on disk. No seed in a browser extension. The encrypted QR is your only backup — and it's honey-encrypted.

Argon2id KDF

64 MB memory, 3 iterations (OWASP recommended). Memory-hard key derivation makes GPU/ASIC attacks impractical.

All Formats

Supports V1 (legacy), V2 (social-bound), V3 (Argon2id + AES-GCM), and V4 (honey encryption) QR formats.
