This is the time of year when bitcoin hardware wallets (signing devices) cannibalize each other over of which is the most open source, adheres to true bitcoin ethos, etc. 🍿🍿🍿

#COLDCARD Firmware Release 1.3.4Q & 5.4.4Mk4 🍄⏫



Read the complete release and upgrade here 📁 https://blog.coinkite.com/spending-policy

🔐 Single-Sig Spending Policies & 📱2FA!

You can now reconfigure your existing COLDCARD with a policy📑, so it will refuse to sign transactions that are too large, too frequent, or sent to an address not on your whitelist

We have also found a way to support **2FA authentication** using the usual phone apps (RFC 6238). If that's enabled, you will not be able to spend using your #COLDCARD unless you also have your phone and provide the correct #GoogleAuthenticator 6-digit numeric code.

Added file rename, Explorer is now offered for transactions of all sizes, NFC improvement, Added @BullBitcoin_, and many other fixes and improvements!

This is amazing! Makes me feel much more comfortable using my Q as a single sig and not using multisig. Unfortunately I guess an attacker who got their hands on the Q would be able to see my entire balance, even if it can't be transferred because of these policies. Very cool update nonetheless!

Sats card/ Tap signer would fit in my wallets, not the Q though!! She a bit too big.

Think twice about recommending google for authentication ( weakest link.. ) April 2023 brought cloud backup where auth codes can be compromised. Google has never had privacy protection foremost…

Spending policies is a great feature! I was wondering if you are planning to support XOR + passphrase in the future to benefit from a passphrase-modified main seed and XOR it with the spending policy seed? I think it could be a great mix!!
