Are you asking if you should have a second node to do zaps? Then, no, don't.

Install #lnbits on your node and you'll be able to create sandboxed wallets on your node. You can have a sub-wallet on your nose just for zaps. And then, you can add a second wallet you can use for #Cashu. That's what I do. I even have another wallet setup for selling stuff using #btcpayserver.
