'How does online cryptocurrency wallets get full balance of mnemonic phrase?
What am I talking about? Let's imagine that any of cryptowallet's is a just function that have only one argument - mnemonic phrase like 12/24 words. I can get new mnemonic on a blockchain.com and paste in, for example, in Binance's Trust - and after that all of them will correctly count my balance.
Referring to some BIP's which are saying much info about derivation pathes - them are just human readable string like m/0/0/0/1, where '1' is id of, for example, bitcoin address.
m/44h/0h/0h/0/0: 1AZnveys2k5taGCCF743RtrWGwc58UMeq
m/44h/0h/0h/0/1: 1AMYJTJyV4o1hwNACJtfdXBW6BiD1f5FXb
m/44h/0h/0h/0/2: 1NPFFtSiFRatoeUf35rwYb8j8C1u7sVhGa
m/44h/0h/0h/0/3: 1L44VTYEzWesp8cxnXcPGbUzuwTYoSW9at
How in this situation another wallet should know how much of indexes I used in first wallet to count all balance from all addresses? Is it real that they are just counting all indexes from first to last?
P.S. talking exactly about b-n.com and Trust - they are using different "accounts" (last '0h' in the DP) so if I have some coins on b-n.com I won't see them in Trust. But, for example, Trezor or Ledger works somewhy and count really full balance of mnemonic?
