Vanity contract address using CREATE2?

Support
1

I would like to get a vanity contract address.

Just like 1INCH: https://etherscan.io/token/0x111111111117dc0aa78b770fa6a738034120c302

Just like TORN: https://etherscan.io/address/0x77777feddddffc19ff86db637967013e6c6a116c

I would like to deploy to multiple chains: ETH mainnent, xDAI, BSC (Binance Smart Chain).

(I’m not religious about particular chain, some of them have fees that make use prohibitively expensive)

I think that in order to accomplish the same address on multiple chains, I will have to use CREATE2: https://blog.openzeppelin.com/getting-the-most-out-of-create2/

  1. Same contract address on multiple chains (EVM comparible) possible?
  2. Maybe you have a piece of code handy to generate a salt and find such cool addresses?

Thank you for suggestions

Does that helps ?

Hi @marsxr,

The problem appears to be in two parts. How to create a vanity address (trial and error) and how to create the same address on multiple chains.

OpenZeppelin Contracts includes a utility for Create2: https://docs.openzeppelin.com/contracts/3.x/api/utils#Create2

You could look at how EIP1820 registry uses the same address on every network (it also has a vanity address):

There are two parts to this question.

Here is another example: https://github.com/gnosis/safe-contract-deployment-replay

Replaying the deployment, same account, same nonce, same gas price, everything the same.

The reason why I prefer CREATE2 and salt is less private key to manage, I could reuse one of the private keys that I already have in place.

I guess I'll need to figure it out, my use case is not typical :sunglasses:

Hello @marsxr,

I run into that issue a few months ago, and came up with this factory:

It is available on most networks, and there is a package to help you deploy on additional networks, or even on local test chains. It uses create2, so you just have to give it the bytecode and a salt.

I do not have a vanity address generator that, given a bytecode and a regexp would “mine” a salt for you, but it might not be very hard to write one.

Realizing some troubles related to oracle (Chainlink).

BSC and XDAI do not have native oracle system yet.

Some of the DeFi functionality is ETH only.

I may still want to deploy a token on multiple chains, using the same address, using CREATE2

Then the contracts using that token can be a little bit different.

At this point I’m reaching a conclusion that I’m overthinking, paralysis analysis, done is better than perfect.

Hi from 2025! :waving_hand: @marsxr

I stumbled upon this thread while researching CREATE2 vanity addresses.

In case anyone else lands here looking for a solution: I just built a browser-native vanity miner specifically for Safe (Gnosis) that runs entirely on WebGPU.

Unlike older Python/CLI tools, this runs locally in your browser with zero setup/installation and is significantly faster.

It is fully open source (MIT) and the logic can be easily ported to other CREATE2 factories:

I also have a deployed site and a demo video available—let me know if you'd like to see them!
