Discord bot that tracks cryptocurrency and asset prices using Pyth Network and posts updates to Discord channels.

How It Works

1. Price Service fetches prices from Pyth Network every 30 seconds
2. Prices are written to shared JSON file and SQLite database
3. Each bot instance reads prices and updates its Discord nickname
4. Multiple bot instances run in parallel, one per token

Each bot is independent - add more by adding tokens to .env.

Prerequisites

• Docker and Docker Compose
• A Discord application with bot tokens

Setup

1. Copy the example environment file:

   cp .env.example .env
   

2. Edit .env and add your Discord bot tokens. Get tokens from https://discord.com/developers/applications

3. In the Discord developer portal for each bot:

   • Enable "Public Bot"
   • Enable "Server Members Intent"
   • Enable "Message Content Intent"

4. Invite each bot to your server using the OAuth2 URL in the Discord developer portal

5. The CRYPTO_FEEDS variable controls which assets to track:

   CRYPTO_FEEDS=BTC:feed_id,ETH:feed_id,...
   

   Get feed IDs from https://insights.pyth.network/price-feeds?search=btc

Running

Start

docker-compose up -d --build

Check Status

docker-compose ps
docker-compose logs -f

Stop

docker-compose down

Check Bot Status in Discord

!status

Health Check

The health endpoint is available at localhost:8080/health

curl http://localhost:8080/health

Configuration

Update Interval

Edit .env and change UPDATE_INTERVAL_SECONDS (default 12 seconds):

UPDATE_INTERVAL_SECONDS=30

Adding New Assets

1. Add a new bot token in .env: DISCORD_TOKEN_ASSETNAME=your_token
2. Add the Pyth Network feed ID in CRYPTO_FEEDS: ASSETNAME:feed_id
3. Rebuild: docker-compose up -d --build

Adding More Bots

Simply add more tokens to .env:

DISCORD_TOKEN_BTC=your_btc_token
DISCORD_TOKEN_ETH=your_eth_token
DISCORD_TOKEN_NEWTICKER=your_new_token

The bot will automatically spawn new instances for each token.

Bot Commands
