Congratulations on your TAPSIGNER!
The TAPSIGNER is incredibly versatile. For starters, it can be used as the only key in a single-signature wallet. For intermediate and advanced users, it can be paired with other hardware signing devices to create a multisig quorum.
Furthermore, the TAPSIGNER can also be used with our subscription plans, which provide many features beyond basic multisig such as inheritance planning, emergency lockdown, encrypted cloud backups, scheduled payments, and much more.
Regardless of your choice, we are certain you will enjoy using TAPSIGNER with Nunchuk. Bitcoin self-custody has never been this easy.
