Fair enough. The minimum time for the payment is ~1/2mins since Liquid blocks are generated every minute and whatever Boltz takes to find a route.
I'm not sure what the timeout is but I can't imagine it being very long, so probably not getting into hours.
The downsides of swaps vs native LN... but comes with no inbound liquidity, FCs, and channel management nonsense + being fully insulated from onchain fee spikes 🤷♂️
