Support several Accounts of the same CoinType in StoredKey

[grachyov]

I would like to have several accounts of the same CoinType derived from mnemonic.

Would it be ok to extend StoredKey and Wallet functions taking CoinType as a parameter with a new parameter: account's index, while keeping current functions' signatures for backward compatibility?

There is a method on HDWallet to derive a key with custom derivation path, can this be used for your use case?

struct TWPrivateKey *_Nonnull TWHDWalletGetKey(struct TWHDWallet *_Nonnull wallet, enum TWCoinType coin, TWString *_Nonnull derivationPath);

This way I won’t be able to get these accounts later from StoredKey.

That's true. However, in Trust Wallet / Wallet Core we have no plans to support multiple accounts (of the same coin) in a wallet, so if this is a feature request, it is rejected.

Could we discuss how can I add multiple accounts support into WalletCore for wallets needing this feature?

@catenocrypt

Is this backward compatible feature?
What is the complexity for having multiple accounts in one wallet
