Yes I saw where someone posted they had recently used and was a low fee as well. But based on what if seen, MUUN is performing submarine swaps in the backend with is basically onchain fees. I’m not proficient in this technology and only regurgitating what I’ve read, so I could be completely wrong 🤙🏻

Yes, submarine swaps are used. I was under the impression it was LN at times but would use submarine swaps to move funds from on-chain to LN when needed. If that is correct, then it would depend on how much you have in LN channel vs on-chain.
