If you have minibits, either choose the autogenerated minibits address or pay for a custom name.

Paste the minibits address (yourname@minibits.cash ) into the LN Adress box in your Amethyst profile.

When you or your note gets zapped it will be converted to ecash in your minibits wallet.

When you want to zap, just hit the zap button on a note like normal. Choose the amount and minibits will open for you to hit send. Three taps.

Whenever you open minibits and it connects to nostr relays all your zaps will appear in the wallet.

This is a custodial solution that bridges LN payments to ecash and vice versa.
