Udun Cold T1
Our wallet review process
We examine wallets starting at the code level and continue all the way up to the finished app that lives on your device. Provided below is an outline of each of these steps along with security tips for you and general test results.
Application build test result
We found that this product looks to be very similar to. Like Ellipal, it resembles a mobile phone with a screen display and button.
From the website’s English alternative in the hardware wallet’s page:
Integrated and sealed all-metal body, a cold wallet that safely isolates the network.
We found another page concerning this product on the orginal website.
The hardware wallet is physically isolated, and the private key encryption never touches the Internet. Physical isolation, tamper-proof and tamper-proof, does not require any trust.
It also claims that the wallet supports “33 public chains and thousands of tokens.”
The site asks you to sign in or create an account before you can access the shop page.
Here is a video showcasing this product. At 0:30, the video shows the user making a transaction on the app and then confirming the transaction on the wallet. This is done by scanning the QR code generated by the hardware wallet.
UDUN has a Github account although none of the repositories held any relevant results for the wallet’s firmware. With no information concerning this from the providers, we have to assume that the wallet’s source code is not up for review.

Do your own research
In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
