I am working on a project where people can contribute to the project in Bitcoin or Ethereum. For each I need a way to be able to display an active balance in each currency's wallet. Something along the lines of this:
You have elected to contribute in BTC to the project. Thank you. Your contributions are most welcome. Please send your BTC to 123abc456def. This wallet currently contains X Bitcoins, while Y have been contributed in total, and the contributed funds have been used for the purposes listed below.
And each time the person accesses the page, X and Y will reflect that wallet at that moment. I'd really prefer not to run a full copy of the blockchain for this. I already have bitcoind running with a 4GB pruned database, and I'm hoping that will be enough.
I need to do all this in PHP. Is there a good PHP toolkit/library/whatever that I can use to call the info?
