I recently read that Ethereum doesn't use the part of the BIP44 derivation path dedicated to accounts.
Ledger Live uses the account section of the BIP44 derivation path. No one else does, afaik.
I just tried generating addresses under this path m/44'/60'/1'/0/n, opened MyCrypto with my Trezor and I can access such derivation path. Also, I can see and send funds from these addresses.
The part of
m/44'/60'/1'/0/ that is the
account is this bit =>
What MyCrypto does is increment the
address portion of a derivation path to generate the keypairs that are shown on the website. Changing the
account section just means that you're changing the base derivation path that is used. The
address section is still what is being incremented on MyCrypto. As long as the derivation path that you use is valid, it'll still be processed the same way.
