<p>I'm creating an exchange like service, I need some for showing all transaction to user like deposit and withdrawal but I'm not using core wallets of any coin, using paper wallets for wallet creation and I want to show balance of user and transaction. So, is there any API available for so that I can fetch such details of user? Please give such API for Altcoins also or provide me name of any wallet through which my task can be completed.</p>

I'm creating an exchange like service, I need some for showing all transaction to user like deposit and withdrawal but I'm not using core wallets of any coin, using paper wallets for wallet creation and I want to show balance of user and transaction. So, is there any API available for so that I can fetch such details of user? Please give such API for Altcoins also or provide me name of any wallet through which my task can be completed.

You may wonder how it is possible to check the balance of an 'offline' paper wallet. It comes down to how Bitcoin (and other Bitcoin-like blockchains) work. At the most basic level, you have a private key. You can generate a public key from the private key and then an address from the public key. Bitcoins are sent to this address.
