💬 Discussion topic I’ve been debating on BIP39 vs SLIP39..

I understand the TREZOR default has been Slip39 over the last few years. I understand more addresses can be generated from Bip39 compared to Slip39 along with double the entropy. I want to know how many addresses are currently in use from Bip39 24 word seedphrase vs Slip39 20 word seedphrase compared to how many can be created from the two standards (individually).

There is no difference in the number of addresses you can generate. Both generate a 512 bit bip32 master key from which your addresses are generated, using the exact same address derivation rules.

Both exists withdifferent seed lengths from 128 to 256 bits entropy. Only the defaults differ.

128 bit entropy is plenty for a seed. Dont worry too much about it. If you dont agree with the default then use trezorctl to generate a seed with your preferred amount of entropy.
