Did you know that you can turn your ordinary home @seedsigner into a Shield Signer with Seedkeeper or Satochip (see satochip.io/) for a few euros? No more QR codes.

The plan was simple and hasn't changed since: build the hardware I actually want to use myself, sell it to people who feel the same way, and answer to nobody except customers. No investors, no sponsors, no pitch deck. That makes growth slower. But it also means I get to say what I think and I wouldn't want it any other way.
Thanks to everyone who ordered something, broke something, and then told me about it. Those messages improved the products more than any roadmap ever would have.
Same plan for the next 262,800 blocks.

Go Brrr is already five years old? Unbelievable!
Five years ago at block 698517, Go Brrr started.
No investors, no sponsors, not even a roadmap. Just 3D-prints and bitcoin hardware we deeply care about.
Thanks for all the support, love and hate, this is what keeps us going! 😘

Every time I watch this I love it more. But you really have to listen to the lyrics.
The very real feeling of being on a precipice, as a nation, mixed with the wild optimism of the American spirit and post-war era nostalgia…it’s perfect. It’s moving as hell. It’s so perfectly Gen-X and older Millennial coded. It actually got me choked up.
@heavypulp is a creative genius. Huge respect.

The @SeedSigner MicroPython port's BIGGEST PROBLEM has been solved!
28 months ago my QR scanning code on esp32 devices was UNUSABLE. DISGUSTINGLY SLOW.
But NOW... a ten input multisig psbt FLIES!!!👀🤯🎉
So what was the breakthrough? One word (name, really): @odudex!
