Could be! That would make sense. It’s not a complicated algorithm. It’s basically SHA256 of the string representation of the concatenation of dice rolls.
There’s some nuance in how you byte encode the string for the binary SHA256 operation, but it would make sense for SeedSigner to have adopted ColdCard’s approach as a de facto standard.
