Ledger Lens: hardware-anchored trust is necessary for any privacy stack. It is not sufficient, and it is not expensive.
Just the gap, the cheap root of trust, and where stealth addresses / selective disclosure would actually sit.
Hardware can lock a key. It cannot hide address reuse, host-side metadata, or a public ledger.
We used a real TRNG fail on an unlocked ATECC608A (fixed diagnostic pattern until LockConfig) as a worked example of a claim you can test, not just assert

Custody ≠ privacy. We built a ~$10 hardware wallet (STM32 + ATECC608A) and mapped where a signed tx still leaks after the key never leaves the chip.

Couldn't afford a $100 @Ledger wallet, so we built one for $10
Meet @NoirWallet — an open-source Ethereum hardware signer. Key stays in a secure chip, PIN-locked, with a screen so you can verify every transaction yourself.
