For self-custodial spending specifically you’ll need an NWC enabled Lightning wallet. I use my Lightning node with @npub1get…0nfm and its AlbyHub.
1. Create and verify your account on @npub1wvs…33pu (card is available for Europeans)
2. Order your virtual or physical card. Virtual can be added on mobile wallets for contactless payments
3. Set up an NWC connection between your LN wallet and your wavespace account
4. Choose the minimum single transaction you want to be able to pay with the card. This amount will be held custodially for payment authorizations. Can be as low as you want - this is your de facto custodial risk.
5. Each time you pay with the card, the exact same amount of BTC is pulled from your connected LN wallet
No need to touch anything after setup. Sats flow from self-custody automatically, as per your set permissions on NWC

Paying with self-custodial BTC has never been easier. @npub1wvs…33pu solved it for Europeans with the wavecard 🤝

I don’t hold ANY fiat, because I know I can liquidate my BTC in seconds, on demand via @nprofile…7vez
Here’s what happens when I need to pay for utilities and make a bank transfer:

2fiat card is a prepaid fiat card that you need to manually sell your BTC into. Huge top up fees as well.

Yes, because it’s a proper VISA debit card that allows me to live on Bitcoin and buy groceries anywhere BTC is not accepted without having to hold any fiat.
The main benefit is that I can spend from-self-custody automatically, so I retain control of my capital.

McDonald’s doesn’t even know that I bought McFlurry with sats straight from my @npub1get…0nfm LN node, thanks to @npub1wvs…33pu ⚡️
You don’t need any permission to live on a Bitcoin standard today!

Connection to self-custody and 1% fees against custodial scam cards that charge 3x more? This is epic 💥
