There are 2 ways you can do to add a wallet address to Addressbook.
Here’s how:
1. Save a wallet address after you send crypto asset.
2. Add a wallet address manually via Addressbook settings. On Pintu app, tap the Account menu at the right bottom of the screen → Tap My Address Book menu → Tap Add New Address button. You can either add addresses of fellow Pintu users or other wallets/exchanges.
