W2QR is an encryption and backup tool for seed phrases. It does not manage keys, sign transactions, or connect to blockchains. Your encrypted QR is a portable backup that works independently of any wallet software.

However, W2QR includes a built-in wallet viewer that lets you check balances, view addresses, and perform basic operations directly in your browser after decrypting your seed phrase — no additional app needed.

You can use W2QR entirely as a "QR code app" without ever installing a wallet like MetaMask or Coinomi. The workflow:

1. 1. Create or import your seed phrase on W2QR
2. 2. Encrypt it into a QR code
3. 3. Use the built-in W2QR wallet to view addresses, check balances, and manage assets
4. 4. When done, close the page — your seed phrase is cleared from memory

Your QR code is your wallet access point. Scan it anytime on any device with a browser.

W2QR encrypts the seed phrase itself, which is blockchain-agnostic. The same encrypted QR works for Ethereum, Bitcoin, Solana, and any other blockchain that uses BIP-39 mnemonics.

The built-in W2QR wallet currently supports viewing addresses and balances for EVM-compatible chains (Ethereum, Polygon, BSC, Arbitrum, etc.). For other chains, decrypt your seed phrase and import it into a chain-specific wallet.

W2QR Cards produce standard BIP-39 seed phrases when activated. The mnemonic derived from a card is identical to one created from scratch — fully compatible with all wallets listed above.

A pre-printed W2QR plastic card contains a honey-encrypted QR. It decrypts to a standard BIP-39 seed phrase compatible with all wallets listed above. Print both your wallet QR and password QR on plastic cards — no wallet compatibility difference between cards and digital QR codes.
