Setting Up the Binary for a t3rn ExecutorThis guide will walk you through setting up the t3rn executor binary on your system. It includes installation steps, code snippets, and configuration details.PrerequisitesBefore proceeding, ensure you have the following:A Unix-based system (Linux/MacOS) or WSL2 for Windows.Rust toolchain installed.Basic knowledge of terminal commands.Steps to Set Up the Executor Binary1. Clone the t3rn RepositoryFirst, 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 BranchEnsure 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 BinaryBuild 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 FilesCreate or edit configuration files required by the executor:Create a config.toml file in the desired directory:mkdir -p ~/.t3rn-executor nano ~/.t3rn-executor/config.toml 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 KeystoreThe 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 "&#x3C;your-private-key>" > ~/.t3rn-executor/keystore/keyfile Replace <your-private-key> with your actual private key.6. Run the ExecutorStart 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.TroubleshootingDependency 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 Resourcest3rn DocumentationRust Official DocumentationWith this setup, your t3rn executor binary should be ready to use!
