Cryptoart is a wallet. It safely stores digital currency, like Bitcoin, in an expressive and collectible form.
The QR code on the front is your public address (works like a bank account number). It can be shared with others. Send Bitcoin to the address using your favorite mobile Bitcoin wallet app.
Once on the art piece, your Bitcoin is safe from hackers and hardware malfunction. As long as the Bitcoin network exists, you can redeem it!
Advanced users that wish to store more than a nominal amount are suggested to exchange the private key and QR code. This can be done without damaging the art piece.
On the back of the art piece is a security sticker. Use the code (called a private key) under the sticker to retrieve the funds with your favorite Bitcoin wallet software.
