Is it possible to get the initial balances for all those accounts who bought ERC20 tokens? If that’s possible, how that can be achieved?
I’m wondering if there is any way of getting that information for each ERC20 token contract via for example the neon rpc from my get client. I know there is the method eth_call that I can use against each token contract’s balance_of function. But for that I needed to know before all accounts who invested in the specific token as well as the block when the token contract was created, assuming that was the initial time.
Am I missing any piece of information that I should consider in order to get initial balances for all tokens investors/accounts for a given erc20 token? Should I consider get that information from the token ico contract? It comes to that, I’m assuming there is no pattern on how to get that information as ico contracts doesn’t follow any spec.
