So zapping will now require me to tab out to a different app to approve a spend?
Not necessarily, many wallet connections either require no approval or allow to set a budget within which payments are automatically approved.
So zapping will now incur lightning fees?
Yes, you pay for the route to our node. We pay the network fees for the route to the recipient from the 30% we take for rewards and territory revenue.
For small zaps, it can be a high percentage due to base fees (1 sat fee for 1 sat payments). If you want zero fees, open a channel to SN.
If the recipient is offline (say a mobile wallet), the zap will fail?
Yes. If your wallet fails too much, we might disable it and you'll receive cowboy credits instead until you fixed your wallet and want to try it again.
Why are some wallets send only (like Blink)? I like Blink as an intermediary because it obfuscates my identity (I don't reveal my main LND node, which I may want to associate with a different identity).
You can use Blink for receiving via its lightning address.
If a wallet does not support sending receiving, it's either because we haven't implemented it yet or because they don't support running on the server (like WebLN).
