Ethereum Address Generator

Description

This Rust application generates a new address for the Ethereum network. It creates a private-public key pair and then derives an Ethereum address from this pair. If the generated address starts with a specific prefix (e.g., "0x123456"), the address and the keys are saved into a file named addresses.json.

Dependencies

• anyhow
• secp256k1
• tiny_keccak
• web3
• serde_json
• tokio
• std

Installation

First, clone the project:

git clone https://github.com/codeesura/Ethereum-address-generator-rust.git
cd Ethereum-address-generator-rust

Then, install the dependencies:

cargo build && cargo run

Usage

While in the project's main directory, run the application with:

How It Works

1. Key Pair Generation and Address Calculation:

   • A new secp256k1 object is instantiated with Secp256k1::new().
   • A timestamp function is defined to create a Random Number Generator (RNG).
   • A key pair (secret_key and pub_key) is generated using this RNG.
   • The public_key_address function derives an Ethereum address from the given PublicKey object.

2. Filtering Part:

   • The generated Ethereum address is checked to see if it starts with a specific prefix (e.g., "0x123456").
   • If this condition is met, the address and the associated keys are converted into a JSON object.

3. Reading and Writing to File:

   • The addresses.json file is read, and the existing data is fetched.
   • The newly created JSON object is appended to this data.
   • The updated data is written back into the addresses.json file.
