Muun alternative

Hi,

From on of my previous post and after some research, I chose to use Kraken and muun for my DCA with minimum fees.

Kraken to muun lightning and muun to cold wallet on chain.

But here is my problem: I tried transfering funds from moon to my cold wallet with 9sat/vB and after 2weeks it's still not confirmed. So I think I will wait for the transaction to be dropped or failed so I can send it again with a good amount of fees.

So now I'm searching of a muun alternative with the same system of instant lightning/on chain swap but with RBF so I can resend a transaction of I still make this type of mistake.

Thanks for your help !
