Generate a NANO address with a prefix of your choice. The longer the prefix, the longer it'll take to compute.
First, setup Rust. The best way to do this is with rustup.
nano-vanity from crates.io:
cargo install nano-vanity
nano-vanity from source:
If you want to enable GPU support, install OpenCL and add
--features gpu to the install command.

nano-vanity options, use
nano-vanity generates private keys instead of seeds.
You can use these in the desktop wallet (they're refered to as adhoc keys),
however, most other wallets do not yet support them.
You can generate seeds instead of private keys with
Note that doing so is a bit slower.
To explain the difference between seeds and private keys:
- Seeds plus an index (1st key, 2nd key, etc) generate a private key. Currently, this project will always use the first index (index 0).
- A private key generates a public key.
- Addresses are another way of writing public keys.
You can leave a character up to chance by using
You can specify that a character must be a number with
Using your GPU
This project supports using your GPU to compute the address. This utilizes OpenCL, so you'll need OpenCL installed and working.
To build this project with GPU support, pass cargo
To enable GPU use, use the
-g) option. To disable
use of your CPU, use
--threads 0 (or
Intel GPUs are not supported, as in most cases running the code on the integrated GPU is no faster than running it on the CPU.
To change your GPU device, use
--gpu-device [index], where
is the index of your GPU starting at 0.
To change your GPU platform, use
To test the randomness of seeds from this program, you can use dieharder (here's an article on it).
Dieharder should not be taken as proof that this program is secure, however, it should be used as evidence, in combination with an examination of the program's source code.
Here's an example of how to run this with dieharder:
nano-vanity --threads 1 --no-progress --limit 0 --simple-output xrb_1 | cut -d' ' -f1 | xxd -r -p | dieharder -a -g stdin_input_raw
If you get a weak or failed test, run that test again by passing dieharder
While it's statistically unlikely that a test would fail despite nothing being wrong, it can happen,
especially given the number of tests dieharder runs.
To be even more careful, you can modify nano-vanity's parameters.
The important ones are
--simple-output, which makes the output format easily parseable,
-l 0, which generates infinite keys instead of just one.
