Setting Up the Binary for a t3rn Executor
=========================================

This guide will walk you through setting up the t3rn executor binary on your system. It includes installation steps, code snippets, and configuration details.

Prerequisites
-------------

Before proceeding, ensure you have the following:

*   A Unix-based system (Linux/MacOS) or WSL2 for Windows.
    
*   [Rust toolchain](https://www.rust-lang.org/tools/install) installed.
    
*   Basic knowledge of terminal commands.
    

* * *

Steps to Set Up the Executor Binary
-----------------------------------

### 1\. Clone the t3rn Repository

First, clone the official t3rn repository:

    # Clone the repository
    git clone https://github.com/t3rn/t3rn
    
    # Navigate into the repository folder
    cd t3rn
    

### 2\. Switch to the Correct Branch

Ensure you are working on the stable or main branch:

    # Fetch all branches
    git fetch --all
    
    # Switch to the stable branch (if not already)
    git checkout stable
    

### 3\. Build the Binary

Build the executor binary using the Rust toolchain:

    # Clean previous builds (optional)
    cargo clean
    
    # Build the executor binary
    cargo build --release -p t3rn-executor
    

Once the build completes, you will find the binary in the `./target/release/` directory.

### 4\. Set Up Configuration Files

Create or edit configuration files required by the executor:

1.  Create a `config.toml` file in the desired directory:
    
        mkdir -p ~/.t3rn-executor
        nano ~/.t3rn-executor/config.toml
        
    
2.  Add the following example configuration:
    
        [executor]
        rpc_endpoint = "ws://127.0.0.1:9944"
        keystore_path = "~/.t3rn-executor/keystore"
        network_id = "0x12345678"
        
        [logging]
        level = "info"
        
    

### 5\. Initialize Keystore

The executor requires a keystore to sign transactions. Set it up as follows:

    # Create the keystore directory
    mkdir -p ~/.t3rn-executor/keystore
    
    # Add a keypair (example with a test key)
    echo "<your-private-key>" > ~/.t3rn-executor/keystore/keyfile
    

Replace `<your-private-key>` with your actual private key.

### 6\. Run the Executor

Start the executor using the built binary:

    # Navigate to the release directory
    cd ./target/release
    
    # Run the executor binary
    ./t3rn-executor --config ~/.t3rn-executor/config.toml
    

You should see logs indicating the executor is connected to the RPC endpoint and ready to handle tasks.

Troubleshooting
---------------

*   **Dependency Issues:** If `cargo build` fails, run:
    
        rustup update
        cargo check
        
    
*   **Permission Denied:** Ensure the binary has execution permissions:
    
        chmod +x ./t3rn-executor
        
    
*   **Network Issues:** Verify the RPC endpoint is reachable using:
    
        curl ws://127.0.0.1:9944
        
    

* * *

Additional Resources
--------------------

*   [t3rn Documentation](https://docs.t3rn.io/)
    
*   [Rust Official Documentation](https://doc.rust-lang.org/)
    

With this setup, your t3rn executor binary should be ready to use!
