Important info about our project's security model.
TLDR: Releases are only published in our official repo, and make sure to verify your downloads as authentic.
You are the software authenticity assurance.
The foundation of @SeedSigner's security model relies on users taking on the responsibility to ensure they are running valid software -- because we use off-the-shelf parts, the hardware will run any code that you load on it.
Instructions on downloading and cryptographically validating that you have our released software can be found at:
github.com/SeedSigner/seedsi…
The ONLY place where we release binaries is in our Github repo:
github.com/SeedSigner/seedsi…
The project's PGP key that has been published on multiple platforms can be found at:
keybase.io/seedsigner
Our software releases are deterministic and can also be built from source to validate our released binaries. Building from source is not as difficult as you would think, instructions can be found at:
github.com/SeedSigner/seedsi…
We also have an awesome community in our Telegram channel where you can find earnest help should you need it with any of the above:
t.me/joinchat/GHNuc_nhNQjLPW…
Note that Telegram is not perfect and impostors may DM you offering help -- any technical help from Telegram should happen **out in the open** within the main community chat.

BULL Wallet version 6.14 is out!
Here’s what’s new:
• Lightning payments and L-BTC to on-chain Bitcoin transfers are back.
• Auto-buy and Limit Orders are now available in the wallet’s Exchange section.
• New built-in secure keyboard for entering your recovery phrase.
• Rebuilt Tor integration.
• Smoother @SeedSigner workflow.

Ever since we took down the blockclock. Citadel coffee lacks a dedicated block clock.
So with a soare pi and an e ink screen (13") we created an automatically updating hourly newspaper showing blockheight and clock.
Now to print a good looking frame for it.

Yowza, reading dice rolls w/@SeedSigner camera!
What a formula:
* Go to @tabconf (moar, please @miketwenty1).
* Demo proposed feature to us in person.
* Attend my workshop, get esp32-P4 hardware.
* Build an even better version!
I'm super impressed, @onedigitmoney!
Scan all 99 dice into your @SeedSigner in one second. The new hardware (ESP32-P4 series) -- built-in touchscreen -- much easier to read and use than the Pi Zero.
You can buy a pack of 100 8mm dice from Amazon for $6, so the only constraints are waiting for them to arrive and not losing more than one. 🙂

@seedsigner @KeithMukai 开创了私钥编码的新纪元。
第一次亲手把 CompactSeedQR 一格一格涂出来,像远古先民结绳记事,像古代僧人抄写经卷,又像石匠在碑上刻字。
只是这一次,刻下的不是故事,而是一个人对自己财富的主权。
25×25 个格子,容纳一整个自我托管的世界。

2 years ago I was tinkering with the first prototype of the “Plus” board.
The goal was to upgrade the physical experience of using a @SeedSigner — larger screen for easier reading and better QR xfer, drop the stabby nub for a DPAD, swap microUSB for USBC and get the cord out of the way, and make interfacing with the microSD slot easier. And then bringing the pill shape back was a bonus win.
Myself, @KeithMukai and a Noderunner called “MadBo” (who was also the co-creator of the BTClock) agonized over the specs, sizing and layout for the board. We must have gotten some of the details right because thousands of them have been deployed to bitcoiners around the world, and I think I can safely say that the majority of them have not been produced or sold by me. The design has also been forked to accommodate smart cards, batteries, and in one case, both.
Although open sourcing both the board design as well as the reference enclosure wasn’t the most lucrative path, it was the best one because it’s allowed the magic of the SeedSigner project to make it into the hands of many more people than it might have otherwise, while also materially upgrading their experience of using a signer.
We have much more in store wrt open software AND hardware development with the planned support for microcontroller architectures, but every once in a while it’s fun to glance in the rear view mirror and reflect a little on how far we’ve come. 🧡

It's exciting to see more SeedSigner posts coming from Chinese users over the last few weeks -- that is one of the parts of the world where I think the project has the most potential to make an impact.
爱是会感染的。一个人被感动，就会去感动下一个人。DIY 也一样。
又有人做出了自己的 @SeedSigner。他是看了别人的分享，一块一块零件买来，一步一步组装，最后点亮屏幕。这份喜悦会传给下一个人。
自我保管，不只是掌握私钥，也是掌握自己的硬件：用通用零件，不留下"我买了一台钱包"的痕迹。

In this video, I demonstrate how someone can establish control over a given Bitcoin address using @SeedSigner and @Trezor. @SparrowWallet is of course the wallet coordinator of choice.
Bitcoin message signing provides independently verifiable evidence without moving a single sat.
Showing a Bitcoin balance doesn't prove you control the keys.
This is super relevant for SMSF custody, auditors and proof-of-reserves work.

Also: The esp32-P4 is just the first microcontroller. We'll be able to expand across other esp32 offerings and laterally to other microcontroller ecosystems (e.g. stm32, rp2350, etc).
In the next ~2-3 years: @SeedSigner will run on almost any hardware (within reason).

What's the big deal about the @SeedSigner MicroPython port?
The most important aspect: we'd go from ONE must-have piece of hardware (Pi Zero) to eventually an almost unlimited world of possibilities.
This list is just the beginning.

今天收到一位bitcoin holder发来的照片：他看了我的视频，成功组装了自己的 SeedSigner。
能帮到更多比特币持有者，亲手掌握自己的钥匙，是我做这些分享最开心的事。
每多一个人自己保管私钥，比特币网络就多一分韧性。
你我都是中本聪。 @SeedSigner

All you ever needed is a @SeedSigner
Starless signer was and is the way a sovereign individuals manages and broadcasts his UTXOs.

I totally get the offline laptop thing, I did exactly that for my earliest cold storage. But with what is coming to SeedSigner, SpecterDIY, Krux and Kern, these microcontroller projects are going to offer increasingly decisive advantages over the offline laptop approach. With support for dozens of development boards any association with bitcoin goes away so you sidestep all of the supply chain risk; you lose the attack surface of an entire microprocessor OS + app; you get better assurances wrt wireless comms being truly disabled; you can get something brand new still at a very low cost; the form factor is much easier to use and store; and the UX becomes much more intuitive and specialized like a HWW rather than a general purpose computer/OS. The advantages of FOSS + DIY are going to become undeniable.

From our independent self custody guide (aka the @SeedSigner manifesto), published in early 2022:
. The importance of multisig
. An increasing separation between protocol ops and PK ops
. The opportunity of statelessness
. The importance of DIY for minimizing trust
Still highly relevant and worth checking out:

Pretty cool: @RichLassiterMD got one of the @SeedSigner dev boards and then took it to @ALewin's @tabconf AI hackathon.
Rich created a smart home controller app that's a decoy on top of the SeedSigner MicroPython port!
He is NOT a programmer. But did this in 1hr!
The @SeedSigner workshop at @tabconf was a success!
About 25 people showed up, received their free esp32-P4 dev board, and nearly everyone had flashed my work-in-progress MicroPython port to their board by the end of the hour!
Excited to see what they build!!

The @tabconf @SeedSigner workshop fundraiser is now OVER funded!
Thank you, everyone!
Workshop attendees will go home with this hardware. It'll help seed the next round of new devs for SeedSigner, #Kern, @selfcustodykrux, @SpecterDIY, and probably many new projects as well!
