I found one interesting thing about Secure Element microchip ATECC608A that is used in hardware wallets like Coldcard, Passport and Bitbox.
It can be fond and purchased online or in stores very easy for price of 1 usd (or less than 1 euro), and price goes even lower if you purchase it in a bulk.
Than you only need to found a schematic and make your own diy secure hardware wallet.

Yup, I know about this - I never thought that I pay 100+ bucks for the secure chip, that's never been on my mind to be honest, I was always like 'I pay for the R & D' Grin

But to be honest, I would need more than 10 hours to 'clone' a BitBox, which means I'd work below minimum wage to DIY it instead of just buying it. That's why it wouldn't make so much sense in my opinion.

However, it's good that they're readily available, so that at least in theory, you can have 'reproducible builds' of the hardware and not only the software / firmware.

One example from microchip.com website:
1-24 chips = $0.90
25-99 chips = $0.75
100-999 chips = $0.68
1000-4999 chips = $0.63
5000-9999 chips = $0.61
10000+ chips = $0.56

I couldn't find exact price for other secured element chips used in other wallets, but I doubt they cost more than a few bucks, so better think about that next time you want to spend money on some hardware wallet. Wink

Hey,
First of all, I would like to thank you for this great topic. It's really important to have such an overview while considering a hardware wallet.
May I ask you to add our product ?

It's called Satochip, based on a smart card, this hardware wallet is open source and build on the NXP JCOP interface.

Sure you can, Satochip is now added to the list in first page.
I don't have plan to list every single hardware wallet that exist in the world, so it is possible that some of them are still missing.

Thank you for the quick shot Wink

I can help you with that part but I'd like to request not meriting my post for a code that it's just an alteration of what you already have posted in this thread.
^{- The credit part is more than enough}

Thanks buddy for helping and for wonderful work with this table!
I checked everything, made few small corrections, updated first post and it looks much better than my old frankenstein list Cheesy

I tried making my own table but I always messed up thing when creating new lines, so maybe I will contact you in again in future for small assistance.

I am not great in making forum tables so.... is there anyone who can help me to create simple table form and improve my first post to list all hardware wallets and secure elements?
This should ideally have 5 sections, hardware wallet name, wallet Open Source YES/NO section, Secure Element YES/NO section, Type and model of secure element section, EAL Evaluation Assurance Level setion.
Anyone who help me with this task will be rewarded with some merits and he will be credited for his work.
You can write in this post or contact me with PM.

Not sure about the CC EAL 7 certification of NGRAVE.
I was not able to find the certification here: https://www.commoncriteriaportal.org/products/certified_products.csv

I don't know what kind of ''holy grail'' csv file you are showing us here, but Ngrave hardware wallet is not officially released yet, you can only pre-order it, so it's normal that secure element is not revealed and we don't know exact certification level.
Only information we have is from their website claiming they have CC EAL7 certification.

List is updated with KeyStone Hardware wallet that have EAL5+ certification and 32-bit ARM Cortex-M0 secure element, like they announced on their github page with datasheet document.
KeyStone wallet is almost identical with Cobo Vault that stopped with production of their hardware wallet, and main developer with his team created new company with same components and few improvements.
I am not sure this is the best choice for secure elements, as similar cheap Cortex-M0 STM chips are often used as regular processors and not as secure elements, and Keystone is still hiding exact model they are using.
Ledger for example is using non-secure STM32 Cortex-M processor is combination with secure element ST31H320, and other hardware wallets are doing something similar.

Quote

Keystone's Secure Element is a 32-bit security microcontroller, which is specifically targeted at low-cost and low-power fields. The Secure Element is an ARM Cortex M0 microcontroller integrated with a variety of secure cryptographic modules, including the SM1, SM2, SM3, SM4 algorithm, as well as RSA/ECC, DES/3DES, AES128, AES192/256, SHA1/256, SHA384/512 and other internationally recognized security algorithms. It supports true random number generation (TNRG). The Secure Element provides a variety of peripheral interfaces: USB2.0 full speed, SPI, UART, ISO7816, I2C, etc. built-in ROSC, and also supports crystal-free applications.

Keystone's Secure Element has a 256K byte on-chip eFlash, 16K bytes of ROM, 16K bytes of on-chip SRAM, and 4K bytes of dedicated SRAM algorithm, of which on-chip ROM provides various algorithm interface programs for developers. It improves the development efficiency and optimizes system performance.

A few days ago, Tropic Square confirmed that their chip is expected to be available somewhere in 2022 and there doesn't seem to be any major problems which could delay the release. Still, I would not expect a new Trezor hardware wallet before 2023.

Great news and they commented that goal for them is to release it in 2022 and that Secure Element will be available for everybody and not just for hardware wallets.
As Ledger collected bunch of money in their latest fundraising it would be interesting to see if they join this race of developing their own open source alternative, or they will continue to waste more time and money on supporting altcoins.
Hardware wallet wars are just getting started Cool

List is updated with two new hardware wallets HyperMate G and HyperMate Pro, both of them are using the same Infineon secure element with EAL 6+ certification but exact model is not stated on their website.
HyperMate is company from China but Infineon is German semiconductor manufacturer and their secure elements are also used in other hardware wallets like Jubiterwallet, Keevo, Secux and Hashwallet.
HyperMate is using Infineon chip in combination with Nordic BLE Chip, and interesting thing is that OLED screen of their hardware devices is directly connected with Secure Element to avoid middleman attacks.

New hardware wallet model CoolWallet Pro introduced new Secure Element J3R110 that has higher evaluation assurance level EAL6+ compared with their older model CoolWallet S, and this chip is often used in smart cards.
I don't see any big improvements or changes and this wallet still remains closed source, so I would look for other alternatives.

Any news about it? Information like what FPGA development board? what Hardware Description Language plataform etc..

Don't expect to see this new Trezor hardware wallet released before late 2022, and I listened to one podcast with Trezor team explaining that it's technically nearly impossible to make 100% open source chip so fast,
and final product will have to wait, but important thing is they have required funding of 4 million euros.
Maybe you can learn more about it from this podcast with Vlad Costea and Slush, and follow @tropicsquare twitter channel for more news:

**Trezor is working on their own fully open source Secure Element chip and they started separate project for this purpose called Tropic Square.

That sounds great, I maybe going to buy a Trezor because of it.. Grin

List of secure elements is updated with new hardware wallet OneKey with HSC32I1 secure element, they claim it's EAL 6+ certified, however on hsec website I found this chip is EAL 4+ certified.
Interesting thing about this chip is that it is made for Huawei after United States imposed a ban on their devices, so Hongsi Electronics created fully compatible clone to replace ATSHA204A chip, using same SHA-256 algorithm with few more added.
OneKey wallet is using HSC32I1 as secondary chip used for holding secrets, along with their main STM32 chip.
