Coldcard Q + Tapsigner Bundle

A ready-made multisig starter: a Coldcard Q signer plus a Tapsigner card as a second key.

Overview

This bundle pairs two Coinkite devices — a Coldcard Q air-gapped signer and a Tapsigner NFC card — as a ready-made starting point for multisignature Bitcoin custody. The idea is to give you two independent signing keys from day one, so you can set up a multisig wallet (for example, requiring 2 of 3 keys to move funds) without sourcing devices separately. The Coldcard Q is a full-featured power-user signer with a keyboard and QR air-gap; the Tapsigner is a slim, tap-to-sign card that acts as a convenient second key.

The strength is convenience and coherence: both devices come from the same reputable maker, work well together, and cover two very different form factors. Buying them together at around $260 is tidy and usually cheaper than separately. The honest caveats are real: multisig is more robust but also more complex than a single-signature wallet, and getting it wrong — losing track of keys, descriptors or backups — can lock you out of your own coins. Sourcing two keys from one vendor also means a shared supply-chain trust assumption.

Buy it if you're ready to run multisig and want a curated, two-device starting kit. If you're new to self-custody, get comfortable with a single hardware wallet first before taking on multisig's added complexity.

Who it’s for

People starting a 2-key multisig who want both devices at once.

Coldcard Q + Tapsigner Bundle: frequently asked questions

Is this a complete multisig wallet?

It provides two of the keys and the hardware. You still set up the multisig quorum, save the wallet descriptor, and back everything up in compatible software.

Is multisig right for a beginner?

Multisig is powerful but more complex. If you're new, learn single-signature custody first — mismanaging keys or descriptors in multisig can lock you out.

Why two keys from one vendor?

It's convenient and interoperable, but some advanced users prefer diversifying vendors to avoid a shared supply-chain trust assumption.

What's the Tapsigner's role?

It serves as a portable second signing key you tap via NFC, complementing the more capable, stationary Coldcard Q.
