About the block claiming at https://bitcore.cc/claim.php
I have literally hundreds of addresses.
And no clue which ones had balances on 2017-04-26

questions:


Do you have a fork of electrum for your coin?

or

Can electrum wallet files be imported into your wallet?
Can bitcoin private keys be imported into your wallet?

or

Do you have an API where I can quickly check a balance for an address?


Thanks
