@SpecterDIY und Specter Shield: Buy the Hardware Wallet for Bitcoiner
Schnuartz @SchnuartzI was the last one a the @cypher_tank pitch Contest in a special format afterwards I showed the judges @SpecterDIY and @ClavaStack
KAVSEC.AGENCY by TosGe ⛓️👨🏼💻 @TosGe995🔥 I ranked 21 Bitcoin signers. 5 years in the shadows: testing hardware wallets, watching Bitcoin Twitter, following every hack, every bug, every vendor drama. This is where I landed, & some of you won't like it. My criteria: 🔓 Open code you can verify 📵 Air-gap: QR or microSD over USB, Bluetooth or NFC 🧱 Security model: secure element, stateless or smartcard 📜 Track record, and how the vendor reacts when things break 🔁 Standard backups (BIP39, PSBT, descriptors): no lock-in 🟥 S TIER Open code, minimal trust in a vendor, and for most of them you can build or flash it yourself. The less you have to trust, the higher it goes. 🟧 A TIER Serious, Bitcoin-focused tools. You trust the vendor more than in S, and you get polish in return. Yes, Coldcard stays in A after July's entropy bug. The transparent fix and migration guide count too. 🟨 B TIER Good tools, each with a trade-off: a server in the security model, a newer approach still proving itself, a phone in the loop, or multi-coin roots. 🟩 C TIER Multi-coin first, Bitcoin second. ⬜ D TIER Closed code, or recovery models where a company holds part of the keys to your castle. Now the twist: no signer is the best in the absolute. The right one depends on YOUR threat model. A ranking expires. A method doesn't. That's the whole idea behind chapter 23 of Bitcoin Hodler: Choosing Your Signer. 📖 Where would you move one device? 👇
Coinjoined Chris ⚡ @coinjoinedNow @_polto_ from the Specter Association makes @Schnuartz case for air-gapped signing He highlights why separating communication channels matters for hardware wallet security. Using microSD cards for firmware updates and QR codes for signing keeps these processes isolated, reducing shared attack surfaces. Combined with open standards and interoperability, air-gapped devices may aleo reduce dependence on manufacturer-controlled companion apps, avoiding another potential single point of failure.
