Using Bitcoin SV is like using email — you send funds “from:” your wallet “to:” another wallet. Nobl makes it easy. To access your wallet, you will need to set a PIN and use it each time you open your wallet. This way, you can be sure your funds are safe, even if your phone gets into the wrong hands.
In the wallet settings is a backup button. Write down the 12 words displayed and keep them in a safe place. As long as you have that backup phrase, you can always access your funds.
