This is Nostr’s main web client with Monero zaps (also supports BTC Lightning). Optimized for web browsers, it uses QR codes to pay from your mobile wallet. The Monero address is stored via NIP-78 on the relays. You can also bundle up to 20 zaps into a single transaction to avoid the 10-block lockup.

Web-only (no native desktop or dedicated mobile app)
