Bitcoin Price Bot for Nostr

This bot posts Bitcoin price information to Nostr relays at regular intervals.

Setup

1. Clone the repository:

   git clone https://github.com/araujo88/bitcoin-price-bot-nostr.git
   cd bitcoin-price-bot-nostr
   

2. Create a configuration file: Create a file named config.json in the directory /home/ubuntu/.config/bitcoin-price-bot/ with the following structure:

   {
     "relays": {
       "wss://relay1.example.com": {
         "read": true,
         "write": true,
         "search": false
       },
       "wss://relay2.example.com": {
         "read": true,
         "write": true,
         "search": false
       }
     },
     "privatekey": "your_nsec_private_key_here"
   }

   Replace the relay URLs with the Nostr relays you want to use, and add your nsec (private key) to the "privatekey" field.

3. Set up environment variables: Create a .env file in the root directory of the project and add your CoinAPI key:

   API_KEY=your_coinapi_key_here
   

Usage

To run the bot:

go run main.go

The bot will fetch Bitcoin prices for USD, EUR and BRL daily and post them to the configured Nostr relays.

Configuration

• The config.json file specifies the Nostr relays to connect to and the private key for signing messages.
• The .env file contains the API key for CoinAPI, which is used to fetch Bitcoin price data.

Features

• Fetches Bitcoin prices for multiple currencies (USD, EUR, JPY, GBP, BRL)
• Posts price information to Nostr relays hourly
• Configurable relays and private key

Dependencies

This project uses the following main dependencies:

• github.com/nbd-wtf/go-nostr: For Nostr protocol implementation
• github.com/joho/godotenv: For loading environment variables

Make sure to run go mod tidy to fetch all required dependencies.

Note

Ensure that you keep your private key (nsec) secure and do not share it publicly. The config.json file containing your private key should be kept confidential.
