Use bitcoinguide/seed and iancoleman to check that the dice entropy you generate on the coldcard gives you the same 24 words. Maplebitcoin has a YouTube video explaining it very well, it's called something like "how to generate your own entropy using dice", he uses a coldcard q in the video

That is my understanding as well.

But that was just a theory...

a 24 word bip39 seed is 256 bits of entropy not 300-400, and the coldcard xors your dice with its own TRNG so weighted dice can't hurt you. just verify the checksum on export. nostr:nprofile1qy2hwumn8ghj7etyv4hzumn0wd68ytnvv9hxgqgcwaehxw309akxjemgw3hxjmn8wfjkccte9e3k7mgqypvu4mlnfxkslg6ztjwu8j9zwqwdf...

Were you able to wipe the old seed? Mine (mk4) wouldn't do it despite multiple attempts.

I would add a strong passphrase as well as a minimum. I’m going multivendor multisig after this.

I have been thinking about this all day
