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.

I spent months complaining that someone should build this... and eventually realized that someone had to be me. So here we are.

I also leaned heavily on AI during the process — it’s never been easier (or more fun) to create apps for open platforms like Nostr. If you have an idea, you really can just build it. No gatekeepers, no permission needed. Just ship it.

Peace

Calle can lock his payment token to all three of us, requiring 2-of-3 signatures to redeem... and specify a time limit for performance.

The token can be sent up front, and all parties can see the lock using Cashu Witness.

If the deal goes through, I can witness the token and send it on to HeidE, who can then sign and swap it for an unlocked token she can spend (again using Cashu Witness).

If the deal falls through, I witness the token and send it back to Calle to cash in.

if I get hit by a bus or the deal isn't done in time, Calle can cash in the token when the the token lock expires.
