BAM- nabbed it.
I was trying to explain ecash via cashu to a friend. i found it more difficult to explain than I anticipated but the example nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg used for blind signatures helped a lot. think I left out the mint part actually. shame on me
