With Cashu 402 the merchant / receiver decides which mints are used to pay. So you choose mints that you have some trust in.

Yes true in that case . Is that any way for Proof of Trust the mint issuer ? If so how ..
isn’t this terrible for the users who tries to pay and it fails? seems like you would only want to do this in the offline case, but accept any + redeem to lightning for everything else
It’s very transparent.

All of this can be automated. If the user does not have a matching token, the wallet will do an automatic mint->mint swap. It’s pretty seamless

Ah nice thats the key bit that makes this work. If the wallet can support this swap automatically then great! very cool.
