- One less secure element [or rather an MCU] chip on the Keystone 3 [2 vs 3 on the Pro version].
- No biometric authentication feature on the Keystone 3.
SourceCorrect.
It should be noted that few days ago they released new version of firmware 1.2.4 with open-source code verification of firmware.
However, I didn't see any confirmation for this on WalletScrutiny website so far, but their code was audited by
Slowmist.
few weeks ago
https://github.com/KeystoneHQ/keystone3-firmware/releasesFirmware Checksum Verification can easily be done:
https://guide.keyst.one/docs/firmware-checksumAnd they posted Comprehensive Guide to Building and Verifying Keystone3 Firmware:
https://github.com/KeystoneHQ/keystone3-firmware/blob/release/v1.2.4/docs/verify.mdYeah, $160 is the hell of price for Keystone 3. For Russian people the better and at the same time more affordable opt would be to spend $ 74.90 for
AirGap Knox , download free AirGap Vault&AirGap Wallet and turn their Android +10 smartphone into airgapped device with the security which at least is not worse than security held out promises by Keystone 3 HW.
I see they are sponsored by Tezos and bunch of other shitcoin companies.
Doesn't look good to me, and android phones can never be safe enough, unless you physically remove antennas and modes.
"E4pizor is a hardware wallet assembled by the e4pool.com crypto team, which is a complete analogue of the original Trezor One wallet, which initially has open source firmware distributed along with layouts of printed circuit boards, cases, etc. by the company itself, the creator of the Trezor wallet - SatoshiLabs under free licenses."
First time I see this, but I saw many other trezor one clones.
You can easily make your own Seedsigner and Krux wallets.
They are one of the best available DIY airgapped devices available right now.
