Assuming speed of 5.8million keys a second

GUI Usage

After finding an address, create a new Monero wallet: Input the address, private view key, and private spend key: And verify your new wallet address is correct:

CLI Usage

```bash Usage: monero-vanity [--OPTIONS]

Options: -t, --threads How many threads to use [default: HALF_THREADS] -p, --pattern Address regex pattern to look for -f, --first Start from 1st character instead of: ^4.PATTERN.*$ -r, --refresh How many milliseconds in-between output refreshes [default: 500] -v, --version Print version -h, --help Print help (see more with '--help') Example 1 - Basic pattern using half threads: bash ./monero-vanity --pattern hinto

44hinto... ```

Example 2 - Advanced regex pattern using half threads: ```bash ./monero-vanity --first --pattern "^4(4|8)h(i|1)nto.*$"

48hinto... ```

After finding the private spend key: ./monero-wallet-cli --generate-from-spend-key YOUR_WALLET_NAME Enter the private key and the generated wallet will have the address found.

Notes: - Rust regex is allowed in any mode - All characters must be ASCII, Unicode, or a regex pattern - I, O, l, 0, +, / are invalid characters in Monero addresses - Using slightly less than max threads might be faster

monero-vanity automatically prefixes your input with ^4. and suffixes it with .*$ so that your PATTERN starts from the 3rd character until the 43rd character of the address.

Example input: hinto
Actual regex used: ^4.hinto.*$

To disable this, use --first.

Warning: this puts you in full control of the regex, you can input any value, even an impossible one.

Install

Download here.

Cargo

If you have cargo, you can install with: bash cargo install monero-vanity

Arch

If you're using Arch Linux, you can install with: bash paru monero-vanity

Implementation

1. Random [u8; 64] is generated (512 bits/64 bytes)
2. Scalar is created from above bytes
3. EdwardsPoint's base58 encoding is checked (4...) with regex
4. If match, create full address and return to user, else...
5. Increment EdwardsPoint by 1 and continue

Notes: - Each thread seeds its own RNG - The (optional) private view key is also created with 512 random bits

Build

cargo build --release Optimized for your specific CPU (up to 15%~ speed increase): RUSTFLAGS="-C target-cpu=native" cargo build --release

Thanks

Big thanks to kayabaNerve for helping me with ECC cryptography and Rust (he's the reason why it's fast).
