Pythnet Watcher

This project is a Rust-based utility for listening to messages on Pythnet, processing, and signing them.

🚀 Getting Started

🛠️ Build the Project

cargo build --release

Or for development:

cargo build

---

▶️ Run the Project

You can run the project using cargo run by passing the required flags: Make sure to set RUST_LOG=INFO to enable logs from tracing:

RUST_LOG=INFO cargo run -- run \
  --pythnet-url wss://api2.pythnet.pyth.network \
  --server-url https://watcher.pyth.network \
  --secret-key /path/to/secret.key \
  --wormhole-pid H3fxXJ86ADW2PNuDDmZJg6mzTtPxkYCpNuQUTgmJ7AjU

---

🌱 Environment Variables (Optional)

Instead of CLI flags, you can also set environment variables:

export PYTHNET_URL=wss://api2.pythnet.pyth.network
export SERVER_URL=https://watcher.pyth.network
export SECRET_KEY=/path/to/secret.key
export WORMHOLE_PID=H3fxXJ86ADW2PNuDDmZJg6mzTtPxkYCpNuQUTgmJ7AjU
export RUST_LOG=INFO

cargo run

---

🔑 Generate a Secret Key

To generate a new secp256k1 secret key and write it to a file:

RUST_LOG=INFO cargo run -- generate-key --output-file .secret

This will save the key in raw byte format to the file named .secret.

🧪 Testing Locally

To test in a non-production environment (e.g. with devnet or a local Pythnet fork), just provide a different --pythnet-url, and --server-url, and optionally use custom --wormhole-pid.
