As part of Voltage.cloud Nostr services, they are enabling users to create their own NIP05 identifier at their vlt.ge domain and receive Zaps to a non custodial lightning wallet

Once you’ve created your NIP05 domain on Voltage, you can connect your node to your Identifier to start receiving Zaps to your own node! This can be a node inside of Voltage or outside of Voltage.

I’ve tried this with my Voltage node, it works perfectly and it’s free.
