Used my COLDCARD from nostr:npub1wu4aye7ll0lnrrg638e90sehzsgpzx5t39t3mwl05aa0d0ap08esdz3vw0 today to sign a Partially Signed Bitcoin Transaction generated from Specter.

Build the transaction, save the PSBT to a MicroSD card on my desktop, plug that card into my COLDCARD, sign the transaction, plug that card back into my desktop and copy the transaction data to Specter, and then hit "Send".

My private keys never hit a live internet connection.

This always amazes me and takes less time than depositing a check at a branch bank.

It does feel magical, I agree

This is the way

QR scans feel even more magical.

I haven't even tried the QR code yet. I forgot all about it.

I’m definitely an airgap transaction maxi

Is this possible using ipad and micro SD connector? 🫂⚡️

Thanks brother. Will check out. Operating atm without pc but feeling to air gap due to ledger 🤣

I avoid every wallet that caters to shitcoins.

Yeah dude you guys educated me on this 💕

Atm I am keeping #pepe in my #ledger wearing it as necklace 🐸

🤣🤣🤣 just to feel the memes better 🫡

Kinda expensive to pay 180$ for the device to make #pepe somewhat physical experience

(Ofc while compromising your #pepe keys)

Have you tried Sparrow?

I have it but haven’t really used it yet.

I tried Specter Desktop briefly, but prefer Sparrow, mainly because of Electrum server support.

If you only every use either with brand new wallets, then I suspect they’re similarly fast. The difference is when you’re recovering.

I haven’t kept up with Specter development, but when I tried it, it connected directly to your Bitcoin core node. It didn’t support connecting to Electrum server. So that meant that recovering a wallet meant having to scan the block chain, which could take several minutes or longer, depending on the CPU and hard disk speed of the Bitcoin node.

If you use Sparrow with an Electrum server backend, recovery is significantly faster because it uses the Electrum server’s index rather than scanning the Bitcoin core historical data block-by-block.

Now, if Specter has implemented Electrum server connection support, my point is moot. But in any case, recovery speed was a big part of my reason for picking Sparrow.

If you haven’t tested wallet recovery, I recommend it. It’s good practice. 😅

I prefer sparrow because recovery is easier.

I pip installed Specter a couple years ago and tried to teach my wife how to run it.

That was a mistake.

It sounds like a lot, but when you get down to it it's really all pretty straight-forward.

This is the Way.
