Yeah, but I don't think that completely solves the problem. The main problem isn't "can a creator accept crypto paymemts", it's "can we make the payer's experience tome with no friction like it is on nostr" Basically it needs to be a one or two click thing. Not "go to your desktop, find the link to your crypto wallet, open it, etc"
Ithink this can be accomplished with a combo of a wordpress plugin for the payee/creator and the accompanying browser plugin for the payee. You know how you can set your wallet info in a nostr client to zap with? Same thing in the browser. The wordpress plugin would put the zap button on every bpog post. You click/tap it, the browser plugin sends the payment.
