can you tell more about how you coded the fundraiser modal? is it just checking the balances on those addresses then converting them to USD? im sure its a simple solution but i'd be happy to hear more about it - i was thinking of making a similar one for my own project, but it would be good if it displayed different addresses per visitor for better obfuscation...lets say have half of a wallet full of addresses, then also check server side whether the displayed is a valid one [edit: using something like coinbase would solve this, but how could you work it out without a 3rd party and any fees?]
