Seedflow

An interactive, source-linked technical graph of how COLDCARD combines device randomness, required user entropy, BIP39, and BIP32 to generate wallet keys. The graph covers Mk4/Mk5 firmware 5.6.1 and later and Q firmware 1.5.1Q and later.

Every node opens its implementation source. Nodes expose the relevant expression, byte width, and repository path directly in the graph.
