nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq offers swap from onchain to lightning for 0.5%..
Is there a service with better offer?
You could peg in from onchain to liquid which is free, except the single onchain tx fee, with TDex or elements core. Then swap l-btc to lightning on Boltz for 0.1% fee. So overall slightly more than 0.1%.

Or just open a lightning channel directly, maybe with Blixt wallet on the phone if you don't want a dedicated machine running a lightning node
What is the simplest way to do this peg from onchain to liquid (and vice versa if needed)?
Peg in: tdex app or elements core on desktop, both are ways to peg in for free but you have to wait 100 confirmations. If you want it fast its possible to peg in on sideswap for 0.1%.
Peg out: boltz (to lightning), sideswap, or tdex (not sure), bisq
Yes, its a simple app, download from app store, set up, should behave like a normal wallet but there is a peg in option somewhere.
