2. Digital Signature (for Single Adresses only)
Tap on ‘Digital signature’. You will then see your wallet details. If everything is correct, tap on ‘Confirm’.
Next, we will send you an email. From here we will proceed on your computer.

Next, tap 'Sign/Verify Message' at the bottom.
Paste the message that appears in your internet browser onto your computer. In our example, 'Hello, thank you for signing with BlueWallet'.
Then tap 'Sign'.

Then click 'Add Proof' in your browser.
Congratulations! You have successfully signed your address and can use it in your 21bitcoin app to send Bitcoin.
