Awesome, thx
For which of these do I need an account or an app or some bullshit like this?
I know Boltz simply worked without it last time
The ones that require an account are:
- coinos
- hodlhodl
- blink: requires a phone number
- breeze: not to use, but the only way to backup the channels is with a Google account
- deezy: requires an access token which has to be requested by email or telegram so you do need an account

Thanks for this, a couple of nits:
- It's Breez, not Breeze
- You're not differentiating between submarine swaps (trustless) and trusted swaps (there are trusted solutions on the list).
- Breez fee is the same as Boltz for reverse, 0.4%. For swap-in, it's actually channel opening fee, but it's not always required.

Thanks for the feedback! I'm sorry for the typo and for not making the point clear with the fees (rn I'm not sure where I got that Breez charged 0.1 more, perhaps I counted the miner fee as well by mistake).
Regarding trusted and trustless swaps differentiation, you are right. I limited the post to cover the functionality of non-custodial swaps as those are the ones tools like Loop and Boltz use (robosats isn't even a swap service but a P2P exchange that uses HODL invoices for example).
I didn't have enough time to review all the implementations and some of them are closed source, but I included them in the list anyway so everyone has got a picture of how much the market is charging.
reply
Makes sense! Closed source should consider trusted or at least provide a way to validate that the swap is trustless imo.
