Nostr Ynstant Messenger

A lightweight ephemeral chat client built on Nostr protocol, bridging with Bitchat for anonymous, temporary messaging.

Overview

NYM is a Progressive Web App (PWA) chat messenger that uses Nostr's ephemeral events (kinds 20000 and 23333) for public channels and NIP-04 encrypted events (kind 4) for private messages. No registration, no accounts, no persistence - just pick a nym and start chatting. Or, connect using Nostr Extension for persistent identity.

Features

• Ephemeral Identity - Generate temporary keypairs and pseudonym per session or use Nostr extension
• Multiple Channels - Standard channels and geohash-based location channels
• Reactions - React to messages
• Themes - Pick a desired theme from settings
• Private Messaging - Encrypted DMs using NIP-04
• Bitchat Bridge - Compatible with Jack Dorsey's Bitchat

Protocol Implementation

• Ephemeral geohash event kind 20000 and standard channel event kind 23333
• Tags: ['n', nym] for nickname, ['d', channel] for standard channel, ['g', geohash] for geohash channel
