Feature Description

Add Nostr as an alternative verification code delivery method for customer compliance flows, replacing or supplementing SMS verification.

Motivation

  • SMS verification has costs and privacy concerns
  • Nostr provides a decentralized, censorship-resistant communication channel
  • Aligns with Bitcoin/Lightning ecosystem philosophy
  • No dependency on telecom providers

Implementation Considerations

  • Customer provides their Nostr npub during verification flow
  • Server sends verification code as encrypted DM (NIP-04 or NIP-44)
  • Customer confirms code received via Nostr
  • Configure relay(s) to use for sending messages
  • Handle cases where customer doesn't receive message (relay issues)
  • Admin UI configuration for enabling Nostr verification

Technical Notes

  • Could leverage existing nostrclient/nostrrelay infrastructure
  • Need to consider UX for customers unfamiliar with Nostr
  • May want to offer as option alongside SMS rather than full replacement initially
