Muun Wallet 4+

Overall a nice simple wallet. However when tapping on “Receive”, Muun automatically checks the contents of your clipboard. Don’t know why or what it’s doing with what’s in there but this is poor privacy form. Please change this behavior.

Update: developer contacted me to explain that Muun is checking for a BTC address or LN URL which is why it’s reading clipboard. This is poor privacy form. iOS provides an API to check for the existence of a URL. This is all that should be done without user action. The contents of the clipboard themselves should only be read on user action.

Hello! You mean when you tap Receive and the scan button (LNURL) right? If that's correct, this is because Muun's checking if there's a Bitcoin address / LNURL in your clipboard to offer you to use it. Same happens when tapping on "Send". Please notice that this is a client-side verification only. You can verify this in our source code: https://github.com/muun/falcon

Muun’s integration of Lightning and BTC is clean and user friendly more than any wallet I have tested! As a Lightning wallet I can understand the negative reviews for Muun’s high fees (since it uses swaps). But if you want a Lightning-only wallet there are plenty out there.

Muun excels for its efficient and inexpensive swaps from Lightning back to BTC - so much simpler and cheaper than going to Sideswap or Boltz and doing these steps manually.

Here’s a recent test I did of Muun against Breez and Aqua:
Aqua has fees to receive Lightning (or Liquid) and requires a separate swap step before sending. For sending 150k sats Aqua cost 1325 sats to bridge from Lightning to my cold storage wallet, whereas Muun saves a step, does the swap at the time of sending and only cost 575 total sats. (And Breez used Boltz for their swap/send, costing 2360!)

A couple minor drawbacks of Muun, you cannot restore the wallet to another wallet app (only to a Muun app), and you cannot have your Muun account open on two devices simultaneously (unlike Aqua and Green)

Hello Jaggner, thank you for your feedback and kind words about Muun!

We work hard to keep it simple, having a single balance that you can use to send and receive both types of payments, on-chain and off-chain. Also, we are always working to make our Lightning payments cheaper and faster!

Regarding multiple sessions, I'll add your +1 to that requirement. If you want, could you please contact us at support@muun.com and explain why this is important to you? It helps us design a better solution and product.

Lastly, indeed, Muun is not compatible with recovering funds in another wallet provider. Nevertheless, you always have a way to move your funds with your Recovery Tool - even if Muun is no longer available. That assures the self-custody of your funds.

Remember you can always contact us at support@muun.com for any questions you may have! 🚀

Great backup option. Very secure hot wallet. The support of Lightning Network is essential. My biggest complaint is that it cost the same amount of satoshis to send from the Lightning wallet as it does from the Bitcoin wallet in MUUN. If that is fixed then this would be tied for if not the best hot wallet.

Update: I greatly appreciate the response. Now I understand the submarine swap infrastructure. The fees make sense. Since you don’t collect fees I can’t see this wallet being anything but a gift to society. In that, I greatly thank you. I would love a way to add money using Lightning and then spend from that instead of L1.

Hi Manikase, thanks for reaching out and for your detailed message.

Lightning transactions pay a network fee that depends on several factors, including the size of your payment, its route, and the funds you're using.

Additionally, at Muun, some Lightning payments may carry a higher fee if your wallet needs to perform an under-the-hood Bitcoin transaction to complete it because of our submarine swap infrastructure (https://blog.muun.com/a-closer-look-at-submarine-swaps-in-the-lightning-network/). While this implementation offers rock-solid security and self-custodianship guarantees it also implies that some payments require an under-the-hood on-chain transaction with its fees.

We're always working on reducing these to make all payments cheaper and faster. Also, please notice that Muun doesn't collect any of these fees.

Let me know if this sheds some light on how Muun works.

Update: Thank you for your response! It encourages us to keep pushing Muun forward. To the Muun 🚀
