We recently welcomed two new members to the Specter Association.

Marco, who has been working for months on a new UI and UX that has not yet been released.

and

Tadeu, who has neatly implemented the M3Y scanners and improved the QR scan workflow.

Auf dem Specter Desktop Vortrag von @k9ert wurde ebenfalls der Specter DIY thematisiert.

Locktime and nSequence on a DIY hardware wallet?
Oren from Ritrek showed exactly how Specter DIY handles them properly at the Freedom Tech Summit.
Most hardware wallets tap out here. Specter just keeps going. 💪🧡

There is a manipulated Specter Wallet app in the App Store.

That is NOT FROM US.

It tries to hack your Bitcoin.

We DO NOT have a mobile version of Specter! Do not install it.

Only install Specter Desktop on PC from our official site:

🚀 Embit v0.8.1 is now released!
This is a major security and stability upgrade to the core Bitcoin library that powers Specter DIY, Krux, and SeedSigner.
Big step forward for the whole DIY Bitcoin hardware community. 👇

What is embit? Embit is a lightweight, pure Python Bitcoin library that runs on both CPython and MicroPython. It handles key derivation, PSBT signing, Descriptors, Miniscript, Taproot, and much more.
It serves as the foundation for:
- Specter DIY
- Krux
- SeedSigner

Key improvements in v0.8.1:- Enhanced Taproot support (Key Spend signatures in PSBTs)
- Major fixes in the Descriptor parser (tr(), sh(wsh()), etc.)
- Miniscript improvements
- Stronger security — no more bundled native binaries (reduced supply-chain risk)
- Professional release process with SBOM, CodeQL, and more


For Specter DIY this brings:- More stable handling of complex wallets (Multisig + Taproot + Miniscript)
- Better error messages
- Stronger overall firmware security

We’ll integrate v0.8.1 into the next firmware releases.

Krux and SeedSigner also benefit directly from this update — improved stability, better Taproot functionality, and a more secure base for all DIY builders in the ecosystem.
Huge thanks to everyone involved!

Specter does not have a shitcoin version.

Specter Desktop is only Bitcoin only Companion App that you can use as localhost just in the browser.

In this video we are going to speak about what changed in the new Specter DIY v1.10.3 Firmware update.

🔒 𝗦𝗽𝗲𝗰𝘁𝗲𝗿-𝗗𝗜𝗬 𝘃𝟭.𝟭𝟬.𝟯 𝗶𝘀 𝗵𝗲𝗿𝗲.
The headline feature: full transaction transparency when signing — Version, Locktime, sequences and RBF status. Something most hardware wallets still don't show you.
Plus better scanning and expanded multisig support.

𝗡𝗼 𝗺𝗼𝗿𝗲 𝗯𝗹𝗶𝗻𝗱 𝘀𝗶𝗴𝗻𝗶𝗻𝗴.
Transaction Version, Locktime and input sequences (incl. RBF status) are now shown when signing. Particularly useful for timelock recovery flows.
Most other hardware wallets still hide these fields. Thanks to Oren for this one.

𝗠𝟯𝗬 𝘀𝗰𝗮𝗻𝗻𝗲𝗿 𝘀𝘂𝗽𝗽𝗼𝗿𝘁 𝗵𝗮𝘀 𝗹𝗮𝗻𝗱𝗲𝗱.
Smoother scanning experience — no reprogramming necessary, settings work out of the box.

𝗧𝗵𝗲 𝗚𝗠𝟲𝟱 𝘀𝗰𝗮𝗻𝗻𝗲𝗿 𝗷𝘂𝘀𝘁 𝗴𝗼𝘁 𝗮 𝘀𝗲𝗿𝗶𝗼𝘂𝘀 𝘂𝗽𝗴𝗿𝗮𝗱𝗲.
Faster scanning, support for more QR codes, and a fix for newer GM65 units reading CompactSeedQR.

𝗠𝘂𝗹𝘁𝗶𝘀𝗶𝗴 𝘀𝗲𝘁𝘂𝗽𝘀, 𝗻𝗼𝘄 𝘀𝗺𝗮𝗿𝘁𝗲𝗿.
Expanded descriptor detection — more formats recognized automatically when importing.

𝗔 𝗳𝗲𝘄 𝗺𝗼𝗿𝗲 𝗽𝗼𝗹𝗶𝘀𝗵 𝗶𝘁𝗲𝗺𝘀:
New "About" screen.
Button text changed: "Enter BIP-39 password" → "Enter passphrase" (correct terminology).

𝗢𝗻𝗲 𝗶𝗺𝗽𝗼𝗿𝘁𝗮𝗻𝘁 𝗻𝗼𝘁𝗲: 𝘁𝗵𝗶𝘀 𝗶𝘀 𝗮 𝗺𝗮𝗻𝗱𝗮𝘁𝗼𝗿𝘆 𝘂𝗽𝗴𝗿𝗮𝗱𝗲.
We're rotating the signing keys (Ben removed, k9ert added) and shipping an updated bootloader with the new key set.
Skip this release and your device gets stranded on v1.9.0 — no further SD-card upgrades, only JTAG re-flashing.

Feedback welcome via GitHub issues. Thanks to everyone who contributed and tested.

Nobody needs to know that you own a bitcoin hardware Wallet.

🚀We have a clear winner for our challenge!

Standard Specter Shield Lite is 26.15 mm thick.
Motorbrot built a fully functional version only 14.83 mm thin.

Likely reveal how in next Specter DIY Builder Call. After that he can sell his Specter for 1M sats.


Only motorbrot participated in this challenge so we don't have the chance to see another build.

Here is the orginal post of him:

Today is Proof of Keys Day! 🎉

17 years ago, the first Bitcoin block was created

Today, call on the community and new investors to take your Bitcoin off the exchanges and put it into cold storage.
