About Bitcoiner Chat
Bitcoiner Chat is a free web service that issues NIP-05 identifiers for Nostr users. You submit your Nostr name and public key on the page. Once the identifier is accepted, you enter it as your NIP-05 identifier in a Nostr client. The identifier takes the form [email protected].
The service states that it is free of charge and asks users who find it useful to consider a small donation toward server maintenance. Donations can be sent by Lightning Address, BTCPay (on-chain or Lightning), or PayNym. The source does not state any geographic eligibility or usage limits. Questions can be sent to the operator via Nostr.
