Title is misleading. This is not Muun's issue, but lntxbot. This is a telegram bot problem.

Nope. lntxbot sent out correctly the funds. Muun didn't give the user the total funds.

lntxbot isn't respecting the (turned off) MPP flag in the Muun invoice, and making MPP payments anyway.
Muun will add code to detect lntxbot's error, but make no mistake, this is not Muun's problem. They are just improving their wallet in response to the bad code on lntxbot's side.
The missing funds are returned to the sending node because of the problem.

MPP was used for years by all wallet apps. Muun is only now considering to "implement" it? MPP should be used by default for all LN apps. LOL why this shit app is still named as "LN wallet" anyways?

MPP is supported in Muun, and has been. Muun gives control to the invoice creator to DISABLE MPP payments for a particular invoice. This is part of the standard that lntxbot is ignoring.

It looks like the sender (lntxbot) isn't respecting the (turned off) MPP flag in the invoice, and making MPP payments anyway.
We are adding code to detect and reject those payments instead of accepting a single part of the payment.
Thanks again for reporting this!

FUD.. They have fixed the issue at 08/17/2022..
And the remaining fund will return to the sender node.. so there is no losing sats.
Why are you posting with misleading title today?
Even though muun wallet has some problems, it is still the best lightning wallet for beginner.
Please don't be so mean.

Lets play out a scenario so I can choose the right LN wallet.
I only want to consider self-custody options.
Lets say I'd like to load a LN wallet up with 4m sats to prepare for an upcoming month long visit to El Salvador.
Here are the options I'm aware of (suggest a different one if I've missed anything!)
    Option 1: Send an on-chain deposit of 4m sats to Phoenix wallet to "swap-in" and create LN liquidity (150-200 sats to send this). Phoenix charges 1% (40,000 sats) to do this action with a rough cost of $10 at today's bitcoin price. All transactions after that will be very cheap.
    Option 2: Send 4m sats to Muun wallet (150-200sats). Inbound LN transactions have no cost (I have screenshots), and future outbound LN transactions cost about .01% or less of the transaction (again, lots of screenshots).
    Option 3: Run a full node, and connect to it with the Zeus wallet. This allows you to open your own channels, and use tools like https://lightningnetwork.plus/ to get in/outbound liquidity. This has the lowest ongoing fees overall, but requires the person to be more technical, and is out of reach for most of the folks I talk to.
It feels like option 2 is the most attractive from an overall cost perspective. What am I missing? Is there a lower cost option for a self-custody LN wallet?

SBW and Blixt = much better options than Muun.

Look at the responses from the original Twitter thread. This is @lntxbot’s problem not Muun.

Is still Muun's fault: why do you accept partial payment anyways. Could just reject a MPP payment and that's it.

Yes, in the thread Muun said they would make the modification. fiatjaf was on spot saying apps should not expect nor trust other apps to behave correctly. That is the whole idea of btc ethos. Crystal clear for me.

I don’t understand your crusade against Muun … When the community get a better wallet will migrate not because you say so.

I have nothing against any bitcoin app that respect its users. Muun guys are good guys, but they have to get their shit together and do the right things. Bitcoin new users deserve to be warned about all aspects of any bitcoin app and as an old bitcoiner, it is my duty to warn them when something is not good. Of course they can choose to use whatever they like, is not my business to tell them what to choose.

You can repeat 100 times what do you think is better for the others. But until they download other apps, and they get fuck with 3000/2000 sats per channel open or even more for onchain-ln swaps, nobody will take it seriously as an option.

At least, both parties should implement some warnings. I see no users considered from either side. It’s a peril of UX from the brim of hood.
One more suggestion to MUUN, please let users to name their wallets and indicate it’s risks and caveats.

I appreciate your effort. But we need to be vocal about all custodial Lightning Wallets in general. We don't know to which degree they only hold fractional reserves and a lot of people (not your keys, not your coins) could get burned.

No. They get only some shity codes, not actual privkey, not actual seed words. And you cannot import/restore that wallet into another app. Users are fooled.

You can send your funds from Muun into any on-chain address you want using your Recovery Code and the Emergency Kit PDF:

Yes, but it is not bip39 standard, so all the morons in this thread think it’s custodial.
