How can I display amount ETH funded and ICO Tokens received on a webpage in a crowdsale ICO campaign?
The webpage is the personalised customer page after login.
I will display the ethereum adress. When transaction is completed, I want that the customer can see the amount he funded and the amount of the new tokens he received.
I understand, that I can use APIs on etherscan.io, for exemple to get balance of an address. But how do I provide the adress on first login and how can the address stay the same and be displayed for acounts on every login?
Is there a tutorial or template for this?
