Thinking about it some more, maybe the ideal ux is not showing the ecash as valid until it’s been auto-swapped into your mint of trust? nostr:note1gxhgmpc5k8ep0m2zyjn97q2wx32zp7dez0zlpzsvtxu8drzd3f4qrf400v
Probably
I believe so. But at least the difference is that the payment can be pending and be collected asynchronously.
Hedgehog is the other alternative but I don't know enough and it is theoretical/experimental tech for now.
If you don't know the mint, npub or any other entity really, either directly or indirectly (social graph), we have to assume it's not trustworthy. This will become more and more true as Nostr grows nostr:note1m7kskfyz4s9uwrar4swrxyy7wg6d0ufm2gyzeyklzs2dj48kn8mq9djfs5
Is there actual software that treats ecash from an untrusted mint as valid???!!! Seriously???!!!
