phoenix permit to pay on chain reducin the size of the channel, less costly than a submarine swap (but if you dont have a channel already its not woth it).

Coinos is a web based custodial service that permit to receive sats on lightning and send onchain with low fees. Probably the best option for this amount

If you have your sats in Phoenix wallet (among others) you can pay directly to an on-chain address. I believe it’s a channel splice, at least when you receive to Phoenix on-chain, so it you’ll retain one unified Lightning channel but it would decrease your total capacity some.

What I’m not certain of, and where I’ve been unpleasantly surprised in the past, is how much your Lightning capacity is reduced when you send to an on-chain address.

It may be that it only reduces your capacity by approximately the amount you send out, plus some wiggle room, or it may be that it diminishes to just accommodate your current balance plus some extra space.

So if you have a 1M sat channel with a lot of inbound capacity, and you send on-chain with a small Lightning balance (say 100K sats) remaining, it’s possible that your total channel capacity drops to ~120K sats. Or it could be that it just goes to 980K, and I’m frankly not certain.

On the plus side, with fees as low as they are, it’s not that big a deal — you can just send another 900K sats to your Phoenix address and it will splice in to reopen the full capacity.

But I did this when fees were high, and ended up paying a lot. (On-chain fee to send the sats, on-chain fee to shrink the channel, on-chain fee to send more sats to Phoenix and another on-chain fee to splice in and increase my channel capacity again). Today that probably costs a couple thousand sats at most. At the time I think it was upwards of 40K in fees.

Anyway, it works 🫡

Aqua wallet maybe? I dont know if they have a minimum

Send to Muun via lightning. Send from Muun to the onchain address you need to pay. I would only recommend trying this while fees are as low as they are right now.

Unfortunately boltz isn’t great for this

Zeus or WoS are good for crossover transactions but best is manage your own keys and liquidity and move between on and off chain as needed, instead of paying a fee to an LSP

How much is your payment on chain with fees? Maybe ask a friend?

Strike was able to send 5k sats for free on chain took 12 hours though
