This is great, this take the "hardware wallets are expensive" argument away.

This is super cool! I never knew the Jade was this open.

This is gold! I've been looking for a tutorial for the game wallet a lot

Very cool DIY, just ordered the T-Display with the case!

Thank you so much for doing it manually and not using the crutch that is Docker.

Looking forward to the camera version of this tut. Subscribed

Awesome thanks for the video!! I just happen to have purchased one 10usd ESP32 for other purpose no longer in use. Will see how it goes.

Amazing work!

really do enjoy video's like this .. i wonder if its possible to to make the same device but using the onekey firmware .. i like the onekey touch .. but $250 to just see an nft is alittle over price in imo .. i think that the more hands on with a product the better you will understand how to protect yourself in the long run.. most underrated channel on youtube ..

playing with LILYGO display at the moment (10usd the 4mbit with shell option, delivered already in a case) : I had some strange button behavior especially with greenwalet on android. I switched to the official git repo, it is fine now. I have seen they accepted your PR, good job :-)

This is absolutely amazing! one question: If I build it using Ubuntu, will the HW work in windows or only on ubuntu? And why are you using fresh installs for Win and Ubuntu? Is that for security reasons? Thanks!

I updated to the latest version of Jade (1.0.31). Everything was going fine but once it went to the "Update Successful" screen, it just froze on "Update Successful." Now the Jade will not turn on, the device is on, the Green app recognizes the Jade - it says unlock jade to continue. But the LCD 1.1.4 screen is not showing anything.

This is great, thank you!!

Thank you!

Hi, I am stuck at the "idf.py flash monitor" command. I get the "/usr/bin/env: ‘python’: Not a directory" error. Have poked around the internet to get some hints, but none worked. Any suggestion? I'm using Ubuntu (through UTM virtual machine) on my MacOS. Trying to write Jade software on TTGO (Liligo) T-display.

Love the video! I could only get my hands on the regular mstickc for now, and took a stab with that just following the instructions directly. I am running into what looks to be a dependency error on idf version 5.0.2 when flashing. I guess, do you know if it would be ultimately be pretty difficult project to get this up and running on the OG mstickC? I could be wrong, but I do believe the only difference may be the resolution of the screen. All i can find online says its larger, not necessarily higher resolution.

Hi, does this setup with the ttgo display allows a connection with blockstream's blind oracle even if it doesn't has a camera?

thanks was looking at jade. Where did you get the neon sign?

It is low cost but needs an remote server on the internet as an virtual secure element.

is there a really basic instruction sheet somewhere? Do I install ubuntu directly to the TTGO or does that occur with some commands that I saw you use in the video? Does it need a memory card?

How do I upgrade without having secure boot? Just do the same procedure? Or every time I need to update the firmware will I need to reset the wallet and reinsert the seed words?

Amazing stuff, many thanks for this in the name of the whole bitcoin community! I tried to pull your github repo and flash it onto a TTGO, but the Blockstream Green app never worked with any of my phones (bluetooth or usb) so I decided to try to flash the original Jade repo. This worked without any issues, the Green app is now fully working. The only thing I would ask is: 1, Is it enough if I just make these two changes (Disabling Developer & Debug Options) in Jade's original sdkconfig file? At 18:06 I was confused when you showed the difference between sdkconfig files, so I am not sure if I have to make more changes to the original sdkconfig file. I have also managed to enable secureboot, acutally CHATGPT worked brilliantly and managed to get that sorted, so it is no longer recognized as a "DEV" device in BlockStream green. I guess that is enough confirmation. Thanks again!

This is an amazing guide!!!!! I just have one question, should I expect Bluetooth to work? I have an M5 Stack but if I enable Bluetooth and try to pair it to my iOs device using the Green app from Blockstream I get a connection error.

I am stuck at the "idf.py flash monitor" command, getting the "/usr/bin/env: ‘python’: Not a directory" error. I'm trying to download the Jade software onto the TTGO (Liligo) T-Display using Ubuntu on UTM (virtual machine) on a Mac. Have looked around Internet for solution, but no success. Any suggestions?

Got mine working on the T-Display. Good to know I have a backup if my official Jade hardware ever fails. BTW I could not get the "sdkconfig.ttgo_tdisplay_secureboot_noradio.defaults" config to build. It is giving me a linker error. The non-"noradio" version compiled just fine. Not sure if it's and error on my end. Another issue I'm running into is Button 2 (on GPIO 0) does not seem to work when the device has a active serial usb connection. It makes navigating though the menus impossible when the ESP monitor is running or if it's connected to Green via USB. If I close Green it works again. When connected to the phone app over bluetooth it works fine. Not sure if you ran into this. Anyway, thank you for this!

Well, I flashed the secure bootloader and it just came back to a black screen. Assuming I missed a step. How long is a reasonable amount of time for it to generate the encryption keys (using the ttgo t-display)? Its too late now as its powered off but just trying to figure out where I went wrong.

For the ttgo, 4mb flash is plenty enough or would you to the 16mB version?

Which version of the TTGO did you use for this? I see a few different ones in the link you provided. Thanks!

is there any advise how to create a 3D print case for the ESP32?

thank you very much for your videos and explanations about this hardwallet. But my english is not very good. Unable to add *cam to the Lilygo T-display? and it is also not possible to add battery? Am I right?

Is Jade capable of exporting the Seedqr to an offline printer via cable or Bluetooth, so that way I don’t have to be drawing a new seedQR by hand? Or will I have to add in this feature somehow In the code?

Where did you get the B sign? It looks great!

for information, you need a usb-a to usb-c cable for flashing, usb-c to usb-c cable was not working for me

What if we use Tails without connecting it to internet and for sending, just use PSBT? Did you think is it safe enough? Thanks for your great channel

And can we use this DIY hardware gadgets as perfect and secure substitutes of the retail Blockstream Jade sold in the web page? I mean, it has the same entropy and security when it comes to generate secure seed phrases?

Great stuff, but this is only compatible with Bitcoin, right? Is there a good DIY hardware wallet for Bitcoin, Ethereum, Litecoin etc all in one device? And my second question, when I go with the Lilygo TTGO Display, there are two versions available, a 4MB and a 16MB, which one do I have to buy (don't know if they are compatible with each other)?

Hi! The issue I'm having is with the flashing process. I am using my MacBook Pro 2019 to do this and was wondering if there are other options other than Ubuntu and Windows? Both are unable to download onto my computer. I am going to flash onto a Freenove ESP32-Wrover CAM. (I just completed your Trezor video, which was awesome and very helpful thanks!)

thanks very helpful. Is it possible to use TTGO as a temporary signature? or with existing seed? I can't write the words

is this the same level of security as the original jade? i really have to understand.. because it seems as it doesnt connect the pin to jade's servers as with the original one.. and i know theres no secure element either..

thank you! but how to create udev rules for lilygo ttgo t-display

I'm looking to try this, however I'm not too familiar with ubuntu ? Is it possible to make it run through Apple M1 ? Or I need to get a Windows ?

Can you do tutorial on macos terminal? Or does linux tutorial works on macos terminal as well?

Assuming you haven't done the secure boot part of this tutorial, how would you go about factory resetting the M5Stack so that it has the stock firmware again?

great video!! my question: now that m5stack fire is eol, is this project compatible with m5stack core2 which is currently available? they even have a core2 aws version with a secure element, not sure if that's useful since i think the jade doesn't have one in the first place

Are there any downsides to this rather than just buying the blockstream Jade itself? Kind of spooked with the whole Ledger issue.

Do you know if the process is the same for the T-Display S3 board? Thanks for this. I'm going to give it a try.

Hi, I have another question: I flashed a m5stickc successfully and it works rather fine by bt, on the contrary it is not recognised by usb; I would like to know if in your experience it would work by usb (desktop app only supports usb so far)

after running idf.py flash monitor command i get this error: ERROR: The hash sum of the component "espressif/esp32-camera(2.0.3)" does not match the one recorded in your dependencies.lock file. This could be due to a potential spoofing of the download server, or your lock file may have become corrupted. Please review the lock file and verify the download server's authenticity to ensure the component's security and integrity. what should i do?

How to enable bluetooth on TTGO T-Display after Jade is installed?

There are 5 models on the site with ttgo to choose from, which ones are suitable?

May I ask, now that I have Blockstream Jade, can I flashing Blockstream Jade and install Pi Trezor?

can I use T-Display RP2040 if I don't want to use bluetooth?

Hi, again! passing by to say thank you. because I managed to install and activate secure boot. Can you tell me if the version for the M5stickC Plus works on the M5stickC Plus 2?

My TTGO has stopped working after secure boot, I have tried everything possible, but it's no longer receiving data, I only get a "No serial data received" message, and I have tried on several computers, on windows, linux, nothing works. Can you think of a way to fix this? I haven't lost the encryption keys, but it just doesn't receive data anymore.

You didn't mention the fact that ttfo has wifi and Bluetooth built in...

tried lilygo display with electrum, seems there is no way to input the 24 words in an random way like trezor setup. The integrated keyboard is cumbersome... you have a better way ?

I'm trying to install jade on m5stack and I have this problem that I can't solve, during the run of the build it doesn't find jade.elf do you know how to do it?

Will TTGO T-Display S3 work?

Amazing. :)

This is not DIY hardware :c , this is buying hardware and installing DIY (FOSS) software. DIY hardware would be buying components and putting the device together then adding the software on top...

Bro would you suggest me to pick ledger or trezor model T? If trezor because of public code... then what steps would you suggest to do on trezor itself to secure it and not let hackers break it even if they physically access it

My ellipal Titan mini keeps falling out even when is on charge have you ever had that?

its possible install m5stick plus2?

I would never dare to use windows for any of this, randomGenerator has cost untold millions in crypto losses and broken security elsewhere, unix or nothing

Eu fiz a minha seguindo seus passos, ela funciona os aplicativos da green reconhecem a jade em securboot, mas ao criar a carteira quando pede para conectar tanto via bluetooth ou usb quando normalmente seria criado o PIN ela reinicia e não chega a pedir para criar o PIN. Tem algo que eu possa fazer?

Will this work with ESP32 CH9102F?

Thanks its great. If you could go slower I'd appreciate it. Id rather spend another 30 minutes understand everything then feeling insecure about my Bitcoin wallet;)

Hi thank you for this diy tutorial, so I tried enabling the secure boot and got into an issue. I generate the ".pem" but I skipped the "idf.py bootloader" and proceed to "idf.py build" instead. The code finished running without any errors, but the ttgo screen is no longer showing a display. now I tried re flashing the ttgo but I always get the error "Connecting...................................... /dev/cu.usbserial-023883A6 failed to connect: Failed to connect to ESP32: No serial data received. For troubleshooting steps visit: docs.espressif.com/projects/esptool/en/latest/troubleshooting.html A fatal error occurred: Could not connect to an Espressif device on any of the 2 available serial ports." Am I looking at a bricked device? Thanks in advance.

one question: which one of these the most closest alternative to retail jade?
