In response to the ColdCard incident, a new system has been developed to enhance security measures for generating seed words. This innovative approach utilizes ordinary dice and playing cards to create seed words through a simple process. By rolling three dice or dealing three shuffled cards, users can independently generate their own entropy. This method ensures that the entropy generation is offline and free from any potential biases associated with digital processes.

The procedure is straightforward yet effective, catering specifically to those who prefer a more tangible, hands-on method in their security practices. The entire process and its implementation details are available on GitHub, where the system can be freely accessed and reviewed by anyone interested in employing this technique for securing their digital assets. For further information and to explore the repository, visit analog-seed-entropy. This open-source platform not only enhances user autonomy in managing security but also promotes transparency in the methodology used for entropy generation.
