Questions and answers related to all Yoseyomo® products.
What is the difference between one Yoseyomo and another?
All our models share the same dimensions: 50 mm in diameter and 3 mm thick, as well as encryption and concealment capabilities. The only difference is the material they are made of, and in the case of the YSYM2048, which also includes the Crypto Security Fundamental Course for free.
How does Yoseyomo work?
You can find more information, including videos, on our Getting Started page.
To summarize the concept, all crypto wallets worldwide are created following the BIP39 industry standard. This standard consists of a set of 2048 words, from which each wallet randomly selects between 15 and 24 words to generate the seed phrase.
What Yoseyomo allows you to do is use a punch to mark each word in a coded manner on the dot matrix. The 2048 words are arranged alphabetically and assigned a position number. For example, if your first word is "amazing", it corresponds to position 63.
To store it in your Yoseyomo, you simply punch the holes corresponding to the values marked on the metal plate: 32+16+8+4+3+2+1, which add up to 63. This represents the word you want to store and protect.
This way, you encode and store your seed phrase in a highly durable metal plate (in the case of the YSYM2048, made of titanium) to ensure its long-term preservation.
This method prevents you from storing your seed phrase on paper, in a computer notepad, or other mediums that do not guarantee indestructibility or protection against hacking, ensuring the security of all your crypto funds.
Is the marking punch included with the purchase of Yoseyomo?
Yes, each Yoseyomo includes an automatic punch that facilitates metal marking without the need for a hammer.
Is it possible that the BIP39 list will be incompatible or disappear in the future?
Since BIP39 has been a widely adopted standard since 2013, it is unlikely to disappear. However, we are prepared to adapt to new standards if they emerge.
Is it compatible with the SLIP39 list?
Yes, it is fully compatible. Simply visit the SLIP39 page on our website and follow that guide instead of the BIP39 list.
Does Yoseyomo trigger the security alarm at airports?
No, we have tested passing through various security controls at different airports with Yoseyomo in all three available materials, and it has not triggered the alarm in any of them. So, you can safely carry it in your pocket if you need to travel with your Yoseyomo.

Frequently asked questions about shipping, returns and exchanges.
Is there any kind of guarantee for Yoseyomo?

What should I do if my Yoseyomo is damaged or broken?
Use the lifetime warranty by sending an email to support@yoseyomo.com with details and pictures of the damage.
What steps can I take if I lose my Yoseyomo?
The best advice is to withdraw the funds from your wallet as soon as possible to prevent anyone from accessing them if a Yoseyomo is found and deciphered.
After that, create a new wallet from scratch, transfer the funds, and secure your seed phrase with new Yoseyomo devices.
