Could you clarify a bit - specifically how does using Strike with Robosats work for you? You say "when payment fails"...do you mean you're buying btc, and your invoice, that you submitted to robosats, has failed?

If you're buying btc, and your lightning invoice fails repeated, that can be a huge hassle.

However, using boltz.exchange works really well to get the funds directly into btc. You submit a lightning invoice from robosats to boltz.exchange, and it just works. Every single time, no delay, no resubmitting.
