Seed XOR is a security feature of the #Coldcard #hardwarewallet that allows you to split your backup seed phrase into multiple parts, each of which looks and functions like a complete #24-word seed phrase. This makes it more difficult for an attacker to steal your funds, even if they have physical access to one of the parts.
To use #SeedXOR, you will need to create two or more #Seedplates. A Seedplate is a metal sheet that contains a 24-word seed phrase. You can create your own Seedplates or purchase them from #Coinkite.
Once you have created your Seedplates, you can split your original seed phrase into two or more parts by XORing them together. XOR is a #mathematical operation that combines two values to produce a third value. In the case of Seed XOR, the third value is a new 24-word seed phrase that is the XOR of the two original seed phrases.
Each of the split seed phrases can be used to recover your Bitcoin funds. However, you will need all of the split seed phrases in order to do so. This means that if an attacker has physical access to one of the split seed phrases, they will not be able to steal your funds without also having the other split seed phrases.
Seed XOR is a #powerful security feature that can help to protect your Bitcoin funds from theft. However, it is important to note that it is not a perfect security measure. If an attacker has physical access to all of your split seed phrases, they will still be able to steal your funds.
Here are some of the benefits of using Seed XOR:
* It makes it more difficult for an attacker to steal your funds, even if they have physical access to one of the split seed phrases.
* It can be used to create #plausible #deniability, meaning that you can create a split seed phrase that contains only a small amount of funds, while keeping the rest of your funds in a separate split seed phrase.
* It can be used to create a duress seed phrase, which is a split seed phrase that contains only a small amount of funds that you can give to an attacker if you are being coerced.
If you are looking for a way to improve the security of your Bitcoin funds, Seed XOR is a good option to consider. However, it is important to understand the limitations of this security feature before you use it.
