Interface

The interface is defined here.

Common Interface

A single common interface:

1. Initialise with a valid BIP39 phrase and specified network (testnet/mainnet)
2. Get the address, with support for BIP44 path derivations (default is Index 0)
3. Get the balance (UTXO or account-based)
4. Get transaction history for that address
5. Make a simple transfer
6. Get blockchain fee information (standard, fast, fastest)
