Tezos Vanity Address with Seed Phrase

TezosVanity.md

WARNING: Vanity addresses generated with this tool may not be widely supported in various wallets anymore. They may consider the addresses generated with this tool to be "legacy" wallets. Therefore I no longer recommended generating vanity addresses using this method.

After seeing the recently posted How To Generate A Tezos Vanity Address, I thought I'd share a method I've used to generate a vanity address that has the benefit of being able to easily be restored or transferred to another wallet from a seed phrase backup.

Most of the credit goes to Stephen Andrews. I've just slightly modified some of the code he wrote to get it to work the way I want.

Everything below assumes you are working from the Linux command line (tested in Debian/Ubuntu distributions):

First, clone Stephen Andrews' eztz repository from github:

git clone -b vanity https://github.com/stephenandrews/eztz

Then enter the newly created directory and the vanity subdirectory:

cd eztz/vanity

Next, install the needed dependencies with npm (use apt install npm if you don't have npm installed):

npm install

Grab my customized index.js which I called vanity.js here:

wget https://gist.github.com/baketzforme/e27d46d70e949ea9953b11902c2fa4fe/raw/vanity.js

Finally you're ready to generate your vanity address. The below example will search for an address that starts with tz1TERM.

node vanity.js TERM

Example output:

node vanity.js Tz  
Searching for tz1Tz  
Checked 119 hashes  
Found match:  
tz1TzrmTBSuiVHV2VfMnGRMYvTEPCP42oSM8  
giant grunt jewel suit scatter surface chaos tumble radar fortune rifle frost essence motion worry  

You can also optionally include a password. This adds a little more security because the seed words without the password will not import the same address.

node vanity.js TERM PASSWORD

Example output:

node vanity.js Tz secretPassword  
Searching for tz1Tz  
Checked 630 hashes  
Found match:  
tz1TzijVFZT1QmohdSfsBnVAQQa48eWL2xfH  
ramp sea drama balance scale mixed chapter dream hundred sweet language chuckle reform alert clock  

The above seed phrase without the password generates the following address: tz1aBFAMsDGHqnmrhgGhjx9kowjFLJMXEbsC

Just make sure to backup your seed phrase and your password if you use one, or else any funds stored on the generated account could be lost forever.

Enjoy!

vanity.js

#!/usr/bin/env node
const _sodium = require('libsodium-wrappers');
(async() => {
    if (process.argv.length <= 2){
        console.log("Please enter a term to find, with an optional password, e.g. node vanity.js test [password]");
        return;
    }
    var match = process.argv[2];
    var ALPHABET = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'
    for(var i = 0; i < match.length; i++){
        if (ALPHABET.indexOf(match[i]) < 0){
            console.log("Your search term is not valid - please ensure search term only includes b58 valid characters: " + ALPHABET);
            return;
        }
    }
    await _sodium.ready;
    var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
    var ee = require("./main.js");
    var eztz = ee.eztz;
    eztz.library.sodium = _sodium;
    var keys, fmatch = "tz1" + match;
    console.log("Searching for " + fmatch);
    var cc = 0;
    function tick() {
        m = eztz.crypto.generateMnemonic();
        if (process.argv.length > 2) {
          keys = eztz.crypto.generateKeys(m, process.argv[3]);
        } else {
          keys = eztz.crypto.generateKeys(m);
        }
        if (keys.pkh.substr(0, fmatch.length) == fmatch){
            console.log("\nFound match:");
            console.log(keys.pkh);
            console.log(m);
        } else {
            printProgress("Checked " + cc++ + " hashes");
            setImmediate(tick);
        }
    }
    tick();
})();

function printProgress(progress){
    process.stdout.clearLine();
    process.stdout.cursorTo(0);
    process.stdout.write(progress);
}

I no longer recommend using this tool to generate a vanity address, due to the difficulty of importing the address into modern wallets.

We were wondering how to adjust resources to be used in generation?

Sorry, I don't know how to adjust resources used. As far as I know, it will use a single thread and work as fast as it can on that thread. You can run the command multiple times simultaneously if you want it to use multiple threads (one thread per command).

After 2.5 days of generating 4 instances, We received a 5 character address. When importing to Temple wallet it gave Us a different address. Only then did we see your above comment. Do How exactly do we run that? along with the other code?

octez-client can be built from Octez source code, or you can download static binaries. Both of which can be found in the official repository: https://gitlab.com/tezos/tezos/-/releases

Thank you very much for your work, your help, and your quick reply and update.
You are awesome, please take it easy!
