This is general used electronic hardware and it's not connected with Bitcoin in any way, and this DIY bitcoin wallets are not very popular, so I don't see any danger here.
Official shop is always the best place to purchase stuff like this.

That is that is because your not thinking like a paranoid tinfoil hat person. Also keep in mind that compromising device like this would not just be about compromising a hardware Bitcoin wallet, it would be about compromising thousands of IoT things that could be anywhere doing anything giving who knows whom access to who knows what.

Getting some Bitcoin out of the deal would just be a bonus, but how many people would buy some like the field tech I know, and then hook these devices up to whatever and have no clue that they're not original hardware. They look like it, they act like it, but they're not. So who the heck knows what is embedded deep down inside. Could be nothing and these were just cheap knockoffs that they were selling , or they could have some vicious code buried somewhere. Personally I'm going with the benign theory and people are just out to make a buck.

But why risk it, which is why I and then you pointed out that anybody getting these should only be buying them from m5stack.com or their approved suppliers.

Very nice that there is such a big scene of people modding this wallet and creating accessories for it. If I have the opportunity I will definitely try to create a high quality casing
I don't understand why would you need a high quality case for this?  Roll Eyes
It's just a cheap DIY 3d printing that is available anywhere...
People did make premium metal cases for similar DIY devices like SeedSigner, but this is not needed at all and it can only attract attention.

What would maybe be possible would be fill the case with Silikone. Does someone has experience with that?
No.
Silicone is used for isolation, not so much for cases and 3d printing.

From the paranoid tinfoil hat wearing department, be careful where you buy some of these boards from.

You always have the option to buy wallet with cash in store, or use PO box delivery with alternative name and address.
That's what I had to do when I was buying those Ledger Devices.

It’s super cheap to buy them and they end up in every kind of envoirements, scientist, government, businesses etc.. In those kind of envoirments devices like this are also very hard to track, so in my opinion the only reason to counterfeit such a device would really be some kind of malicious activity. I think otherwise the profit would be to small. Is there a good way to see if a chip is real or counterfeit?

Yes & no.
If you buy from them: https://shop.m5stack.com/ you can probably assume it's real. And I would think the ones coming out of their approved resellers are also real.

Beyond that, I don't think you can. A tech I know bought a bunch from them and when he needed more went to what he thought was a reputable site since at the time M5 had no stock. When one died and he sent it back to M5 it came back as not made by us. Looking at them side by side they were the same. Even in the same packing. Their attitude was we sell them and so do these people, getting it elsewhere you are on your own.

So, yes people will clone a $25 thing. Might not even be for evil reasons, just something cheap to make with a good profit margin.
There are even youtube videos about people selling counterfeit IC chips in the $3 range so.....   https://www.youtube.com/watch?v=12u_hBkHB88

Not necessarily anything malicious directed towards Bitcoin wallets, but even at the ridiculously low price points that you could find and online there are still a ton of counterfeits out there.

I'm assuming that they are just cheap knockoffs being passed off as the less cheap real thing. But in the end you don't have a verifiable source of where some of these chips came from or even who did what at the factory when they were assembled.

Why anyone would create a pirate / clone M5 stack is beyond me, but they are out there Sad

Very nice that there is such a big scene of people modding this wallet and creating accessories for it. If I have the opportunity I will definitely try to create a high quality casing for a wallet like this to be able to offer it at a competitive price point to other mainstream wallets. Because so far not really any hardware wallet I know does qualify what I consider a well built case. Well built will for me especially include some kind of moisture and water protection.

People may ask why this is necessary but most of those people are relatively new to the crypto world. After 10 years and many destroyed USB Sticks with wallet.dat files on them you will get more cautious  Wink

What would maybe be possible would be fill the case with Silikone. Does someone has experience with that?

This made me laugh and sad at the same time when I know what experience we had with Ledger. It's hard to break the link unless you convince someone to receive the delivery for you and they don't know what will it be. This way you put them in risk too.

For people who want to break the link there is always a way to do it Wink

Very cool project, what I kind of miss as usual with this devices is a good (3D printed) case option, since the display is nice for just 10 USD, but nothing more then a gimmick without the option to put it in a casing.
There is a bunch of STL files available online for free, so everyone can print their own case version.
I know a guy who printed two case versions, one of them is more square shaped and other with oval shape.

CryptoGuide released one more video with custom cases and added camera:

The more expensive options are nice tho, even also them I would not really consider as more as a gimmick to play around with.


You still have to trust Blockstream to keep all your personal information safe, and hope there won't be any leaks or attacks that will steal and sell your data.

You can consider to let them ship the device to some kind of parcel box like it is usually possible in most countries. With that option a thief will maybe be able to get to your name but that’s all. I think this information will not be enough for somebody really trying to Trackballes down and rob you.

CryptoGuide posted a wonderful video instructions how to do everything, with more details on his github page and this will have secure boot same as original Jade device:

On my watch list and I am still looking for a better way for my crypto to keep safe after ledger came up with this wired wallet backup concept. A multisig wallet is still the safest option for me.

Jade hardware wallet is open source and it's not very expensive, Blockstream is currently selling it for around $65 plus shipping, and there is a 10% discounts if you pay with L-USDT.

You still have to trust Blockstream to keep all your personal information safe, and hope there won't be any leaks or attacks that will steal and sell your data.

Solution for this is to make your own Jade DIY wallet, and there are several options for everyone to choose.

https://www.youtube.com/watch?v=PeqP6oVnlIs

There is one more quick and dirty solution using Blockstream Jade DIY flasher utility BUT in this case there is no secure boot and flash encryption!
This works for TTGO T-Display, M5Stack Fire, M5Stack Black/Gray and M5StickC PLUS.
https://blockstream.github.io/jadediyflasher/

TTGO (Lilygo) T-Display ~$10 USD


https://github.com/3rdIteration/Jade/blob/master/diy/readme.md

M5 StickC-Plus ~$20 USD


https://github.com/3rdIteration/Jade/blob/master/diy/readme.md

M5 Stack Basic ~$40 USD


https://github.com/3rdIteration/Jade/blob/master/diy/readme.md



All this devices are running with Open Source code so I am adding it to my list of DIY open source hardware wallets:
