When people think about hardware wallets, they usually think about securing a seed phrase.

But there is a lot more sensitive information tied to Bitcoin and your digital life.
- Recovery codes.
- Backup instructions.
- Passwords.
- Inheritance notes.

Most of this still ends up in cloud apps, password managers, or email.

Secure Notes on COLDCARD Q gives an offline way to store some of that information on an airgapped device instead.

I’ve been playing around with transferring data between two COLDCARD Qs using encrypted BBQr transfers.

No cables.
No computer connection.
Fully airgapped.

Seeds, backups, secure notes, multisig PSBTs, and more can all be transferred between devices securely.

It’s more simple than I could’ve imagined.

Put together this short clip of the full migration/clone process using microSD.
No USB.
No cloud.
Just airgapped transfer from one device to another.

Not going to lie, it was much easier than I thought it would be.

I’ve been playing with SATSCARD by Coinkite recently.

I’ve been loving how easy it is to use. Load sats onto a card → tap to verify → pass it along.

Feels like a pretty simple way to make Bitcoin more tangible.

When would be the best time to use this? I’ve heard of people using SATSCARDs as wedding gifts or graduation gifts.

I’ve been trying this out recently, PushTX on COLDCARD lets you broadcast a signed transaction with just a tap.

It’s felt like a really simple, smooth signing flow overall.

Curious if anyone else has tried it and what your thoughts are?

Hey folks, I’m a big believer that bitcoin is money and I try to use it to pay for goods and services whenever possible.

I know the importance of self custody, and have tried many wallets. I prefer ColdCard, but also don’t want to take my ColdCard with me when I’m out and about but don’t want to leave any BTC on an exchange.

The best solution I’ve found so far is the Tapsigner. It allows me to self custody on the go. The Tapsigner fits in my wallet like any other card and I can tap and sign transactions on the go.

What other solutions have you guys found to still self custody and also pay for goods and services on the go without having to leave sats on an exchange or hot wallet?

What actually gives you long-term confidence in your Bitcoin setup?

For me, it’s having my hardware wallet built on open standards, with transparent design choices that don’t rely on trust, closed systems, or “just believe us” security models. I want to be able to verify what’s going on, not just assume it’s fine.

That’s why I prefer COLDCARD.

I’d love to hear your thoughts on this. What actually gives you confidence in your setup over the long run?

Been playing around with the COLDCARD Q and wanted to see how “airgapped” signing actually works in practice.

Knowing that my private keys are fully Airgapped gives me a peace of mind. Would love to hear your guys’ thoughts on the ColdCard Q.

Hey Y’all!

When I was first getting into bitcoin a friend recommended I read this article from Nick Szabo about the origins of money. It was extremely helpful and led to me better understanding Bitcoin as money.

I’m posting it here to hopefully help someone out who is at the beginning of their Bitcoin journey.
