There can be many addresses in a Dash wallet. How can I get all utxos and the sum of balance from all addresses by bitcore API? For example, I have a wallet contains 100 addresses, each address has 1 DASH. I want to send 10 DASH to an address with 1 transaction. Actually in bitcore documentation I don't see any wallet-related API, is there any other lib or something to handle this? Thanks.
