BTCPay Server typically requires running a full node, which is a prohibitive exercise for many online merchants w/ shared hosting. I understand why it needs one for lightning, but for on-chain payments using xpub keys, in theory, could it not just generate keys and verify transactions using a remote node or block explorer? Is there any hard, technical reason why it needs a full node aside from "that's how it's coded"?
