PHSM 8 enters mass production this September. Pre-sale opens in August alongside Sovrency.

Built by the best.

Foxconn manufactures your PHSM 8. TSMC fabricates the chip inside it.

Here's what that actually means for the device in your hands (THREAD INCOMING)🧵

Why does this matter for a hardware wallet specifically?

A security device with a manufacturing defect isn't an inconvenience. It's a risk to everything it protects.

Verifiable design + world-class execution.

Our silicon, board, and software are open source, so you can inspect the design.
Built by the best, so you can trust it for generations.

[CrossBar Inc. @crossbar_inc]

@defikadic @wallet Great list. One thing missing: the chip underneath all of them.

@crossbar_inc builds the open-source silicon that makes hardware wallets actually verifiable. Different category, but if you're ranking the stack — we belong on it 🔒

[CrossBar Inc. @crossbar_inc]

Daric is open silicon. Full RTL on GitHub. Open development kit.

Security that can be inspected is security that can be trusted.

This is what the hardware layer of sovereign tech actually looks like 👇

Crypto wallets are built on borrowed silicon. Chips designed for something else, asked to secure everything. That ends now (THREAD POST)🧵

The problem with today's wallets: you need two chips to do the job.

A microcontroller (MCU) for compute. A secure element (SE) for tamper resistance. But bolt them together and you inherit the weaknesses of both.

The private key gets reconstituted on the less-protected MCU. The display showing your address runs outside the secure boundary.

That's not self-custody. That's a long list of attack surfaces.

[CrossBar Inc. @crossbar_inc]

Why ReRAM matters.

Conventional chips store data as trapped electric charge that leaks over time and can be observed through physical attacks.

ReRAM stores information by changing material resistance. Harder to extract. Harder to attack. Built into the chip itself🧱

The crypto engine is a self-contained subsystem isolated from the application processors.

Keys never leave the protected subsystem. Operations chain inside the engine without exposing intermediate secrets to software.

And because CrossBar makes its own silicon, attestation keys and certificates get programmed directly on the factory floor.

The recording is live 👀

CrossBar CEO Mark Davis on CROPS in semiconductors and hardware at BREW Privacy Matters Berlin. If you missed it or want to revisit, here is the hardware security conversation the space needs to be having.

Great to be in that room with @sudo_ml @zmanian @sovright_ ! The hardware layer can't be the blind spot when everything else is being built to last 🔒

Verifiable silicon made the list🔒

Roots of Trust: sovereign tech as the last bastion against AI totalitarianism

A wide ranging discussion in Berlin on the tools and mindsets that prevent AI from turning you into its slave:
- paranoia
- verifiable silicon
- supply chain hygiene
- private internet money
- surveillance with accountability
- farming skillzzz

Will post recording when it’s up

@JphFritsche @zmanian @crossbar_inc @sovright_ @JoinBrewBerlin

[CrossBar Inc. @crossbar_inc]

If decentralization is going all the way down the stack, hardware can't be the blind spot.

Trust should come from transparency and verification.

Why Your Wallet's Hardware Is the Weakest Link Nobody Is Talking About (THREAD POST)🧵

Blockchain protocols are open, verifiable, trustless.

The hardware storing your keys and signing your transactions usually isn't.

Wallets. Phones. Secure elements. Most of it is built on semiconductors that were never designed for secure wallet applications and are largely opaque to the people depending on them.

The real question is what can be verified.

That's what CrossBar is building with Daric, our Secure Processing Unit. Open-source RISC-V core. RTL available wherever third-party IP permits. A platform for hardware verification through IRIS imaging🔬

[CrossBar Inc. @crossbar_inc]

Every privacy guarantee traces back to one question: do you trust the chip?

CrossBar CEO Mark Davis took the stage at BREW Privacy Matters (@JoinBrewBerlin) on June 20th with two sessions: a technical deep-dive into "CROPS" in semiconductors and hardware, then joined @zmanian @sudo_ml @sovright_ on the panel on roots of trust as the last bastion against AI totalitarianism.

"CROPS" is the physical countermeasure layer that determines whether your silicon can be trusted at all. Without it, every layer above is assumption.

That's what CrossBar is building: open, verifiable silicon where the security guarantees go all the way down🔒

Elaine Wang, CBO of CrossBar, took the stage at Sovereign AI Day (@JoinFutura) on June 16 🇩🇪

She broke down exactly how CrossBar is building the hardware layer that Web3 has been missing — open-source silicon, ReRAM-powered security, and on-chip MPC that puts users in full control of their digital assets.

Sovereign AI starts with sovereign hardware. This is what that looks like in practice.
