Oddbean new post about login | logout Ha in the background it is, but luckily for the regular user you won't see any of the tricky bits - it will just work!
How are fees with this approach? I feel like this kind of methods are easily more expensinve than visa/mastercard (just a comparison, I am not criticizing here)
Depends how you use it. I don’t think any Cashu mints charge any fees for Cashu payments. There is rug risk, but that why it’s a great choice only for small payment amounts.
Don't forget Visa/Mastercard fees can be 1-2%, with American Express being even higher... On lightning I pay a lot less fees, the only thing is that in fiat the fees are hidden within the retail prices so they don't feel as bad 😅
With the architecture described for Blitz, you’ll have to pay Boltz swap fees or possibly channel opening fees. Also, sometimes swaps fail and sometimes your channels get forced closed. Custodial lightning is cheap for users. Self-custodial lightning isn’t, but I think that’s okay as long as it’s not hella expensive 😂.
