COLDCARD HAS TWO DICE MODES.

ONE USES COLDCARD ENTROPY AND THEN ADDS USER PROVIDED DICE RANDOMNESS ON TOP. THIS MODE GENERATES A SECURE SEED REGARDLESS OF DICE ROLLS.

THE OTHER IS USER PROVIDED DICE ROLL ENTROPY ONLY. IF A USER DOES NOT BRING ENOUGH RANDOMNESS TO SEED GENERATION IN THIS MODE - RECOMMENDED TO PROVIDE GREATER THAN 100 GOOD DICE ROLLS - THEY CAN GENERATE AN INSECURE SEED. THIS MODE ENABLES AN ADVANCED USER TO GENERATE A SEED IN A REPRODUCIBLE WAY WITHOUT TRUSTING COLDCARD.

seed phrases seem to me a very thin layer for securing my life's wealth... wonder if there are other solutions to this problem.

what do you think about the 3-signature method used by BitKey?

For a small amount of money a seed phrase is usually be secure enough if you make sure nobody has access to it. For a larger amount you can add a passphrase on top which makes the seedphrase useless if someone has accees to the list of words but not the passphrase. For even larger amounts multi-sig wallets such as 3 of 5 or 5 of 7 work but with the added security comes added complexity.

My wallet of choice is the Coldcard paired with Sparrow wallet on my laptop for transactions. I think most decent hardware wallets will allow a passphrase but imo Coldcard is the best.
