How does an offline user generate an ecash token when internet is required to communicate with the mint?

yes, it would display a price in sats

Of course the user would know the price of the TollGate they are communicating with. But at that point, they are offline and unable to generate another ecash token if there is a price mismatch.
I'm asking about when the user is online and preparing to go offline. How does the user know what size ecash token to make beforehand? Are all TollGates the same price? Is that price fixed?
reply
you can generate an offline token, offline, for any amount using most cashu wallets (eg minibits)
an early version of tollgate did require old style tokens (amount is a factor of 2), pretty sure that's resolved now
operator sets the price. amount you pay is the amount you get

Did not know this. TIL, thanks.

I just tried this with the latest release of minibits. I was able to generate an ecash token offline, but still only in powers of 2. Pretty cool feature with a weird limitation. Is it possible to get trustless change?
