This repository provides a simple Hardhat TypeScript script that reads the bytecode of compiled contracts and generates vanity addresses based on regex provided by the developer.
While there are more efficient and faster examples with Rust, this script is practical for simple use cases. It can still generate very unique addresses in a short amount of time, depending on the machine's worker count.
The performance of this salt generation tool heavily depends on the complexity of the regex pattern used for matching addresses. Here are some approximate benchmarks:
-
Simple regex (e.g., matching 2 characters):
- Approximately 10 salt found in 1 second.
-
More complex regex (e.g., matching 4 characters):
- Approximately 1 salt found every ~9 seconds.
Please note that these benchmarks are approximations and may vary based on the specific regex pattern, hardware specifications, and other factors.
1- Clone the repository:
git clone https://github.com/Patronum-Labs/vanity-create2.git
cd vanity-create22- Install the dependencies:
npm install3- Compile the contracts:
npm run build4- Update the script:
- Bytecode of the contract to deploy
- Regex Tester
- Find how many CPU cores do you have - Windows
- Find how many CPU cores do you have - Mac
// Constants
import { bytecode} from "../artifacts/contracts/Lock.sol/Lock.json"; // Either import or set it as a predefined const
const FROM = "0x16A2DDa7E466aE460C5ADd1fBc64dfB8B96E11fb"; // Adjust this based on the address of the create2 deployer
const ADDRESS_REGEX = /^0x*cafe/i; // Adjust this based on the pattern of the address you want to find
const WORKER_COUNT = 16; // Adjust this based on your CPU core count
const ITERATIONS_PER_WORKER = 1_000_000; // Number of random salts generated by each worker5- Run the script:
npm run vanitySalts will be written to the root in Salt.txt.
On each new run, Salt.txt will be reset with new values.
