> Multi path payments is optional for every wallet I've tried that even has it available

Which wallets have you tried? It's built into LND and turned on by default. So any wallets based on LND should just do it.

E.g. most custodial wallets as well as most nodes-in-a-box (Umbrel, Start9, etc.), plus many mobile phones like Breez, Zeus, Blixt, Bitkit, and ShockWallet.

Multipath payments are also turned on in electrum by default and I suspect they are turned on in the other implementations by default too

I checked the Core Lightning github and multipath payments are "on" by default there too. See, for example, this issue: https://github.com/ElementsProject/lightning/issues/3926

It involved an error report where a user encountered this entry too many times in their error logs:

"Detected large payment, splitting into 100 sub-payments"

I checked the Eclair github too and multipath payments are "on" by default whenever trampoline routing is used (which is the case in Phoenix, which always uses Acinq as a trampoline node)

Thanks for the info. Appreciate you bringing the receipts.

I mostly use Zeus now when I use Lightning (which isnt very often), and Atomic Multi Path is optional on it. I just realized I was confusing AMP with MPP. They do similar things but seems like AMP is an improvement over MPP. I haven't checked other LN wallets in quite awhile. Good to be proven wrong and see MPP is on by default more than I previously thought 🔥
