Holy shit it's working! Paid a 100k sats Lightning invoice from two different Cashu mints at the same time.
Enter atomic multinut payments.

All Cashu wallets let you use multiple mints. To reduce rug risk, we encourage users to leave only small amounts on each mint. This introduces a big UX challenge which forces users to distribute funds on different mints in a smart way. It's particularly problematic when you're trying to pay a bigger Lightning invoice from your small balances. Who has time for that?
The Lightning protocol allows nodes to split a single payment HTLC into multiple parts to increase the chance of reaching the destination, called Multi-Path Payments (MPP). Typically, that's done from one sender to one receiver. What if... you can just break the rules?
A multinut payment originates from multiple Lightning nodes to pay a single invoice, atomically. Even if none of your mint balances can cover an invoice, as long as your total balance is large enough, you can pay the invoice.
I don't think anyone was crazy enough to do this before. Pretty sure what you see here is the first invoice being paid using a CLN and an LND node at the same time. Amazing work by the team, special thanks to nostr:nprofile1qqsw8lr88lzln8x92ng073m4v72kglf9edhxvk8eztg3ftny98f46dgpz4mhxue69uhkummnw3ezummcw3ezuer9wchsz9mhwden5te0wfjkccte9ehx7um5wghxyctwvshsz9mhwden5te0wfjkccte9ec8y6tdv9kzumn9wshsk9y93w.
