Aztec Validator Registration Tool

A Rust application that registers a validator in the Aztec network on Sepolia testnet.

Overview

This tool allows you to register as a validator in the Aztec network by:

1. Calculating the forwarder address for your wallet
2. Submitting a transaction to the Staking contract
3. Monitoring the transaction status until it's included in a block

Prerequisites

• Rust (latest stable version)
• Cargo (comes with Rust)
• An Ethereum private key with funds on Sepolia testnet

Installation

1. Clone this repository:

   git clone https://github.com/codeesura/aztec-validator-register.git
   cd aztec-validator-register

2. Create a .env file in the root directory with your private key:

   PRIVATE_KEY=your_private_key_here
   

   (⚠️ Never commit your .env file or share your private key!)

Usage

Build and run the application:

cargo build --release
cargo run --release

The application will:

• Calculate your forwarder address
• Listen for new blocks on Sepolia
• Submit a transaction to register as a validator
• Report on the status of the transaction

Configuration

The application uses the following configuration:

• RPC URL: wss://ethereum-sepolia-rpc.publicnode.com/
• Staking Contract Address: 0xF739D03e98e23A7B65940848aBA8921fF3bAc4b2

You can modify these settings in the src/config.rs file.

Important: Gas Price Configuration

To successfully compete with bots for validator registration, you need to adjust the gas price in src/main.rs:

let gas_price = 1_000_000_000_000; // 1k gwei

This value (currently set to 1,000 GWEI) should be adjusted based on current network conditions. Higher values give your transaction priority but cost more. Modify this value according to your needs and the current gas prices on Sepolia.
