Vanity Contract Address

[0xjluis]

It would be great if you can add this feature.

• Get the wallet private key that in a requested nonce will generate a custom vanity address. I.e. Contract starting with 0xbad..... in the wallet nonce 2

Thanks.

This project is kinda brute-force so it is unable to do it with contract since you must deploy millions/billions contracts to fit your need. Nowadays, deploy a contract into ETH main net costs around $800 each

Wut? @9-9-9-9 The addresses in this project are also calculated via brute force. The only two factors to consider in calculating the contract address are the deployer wallet address and the wallet nonce. And you don't have to deploy to calculate the address, you can do it locally.

@Siul293 idk about this, thanks man

I currently don't have enough knowledge about contracts and contracts addresses, but I might work on it someday if I find enough free time.

@Siul293 I see, so the target is to generate an address with ability to deploy a vanity contract at nonce 2

Or better if can generate a vanity address with ability to deploy a vanity contract at nonce 2

Is that right?

@9-9-9-9 the target is generating an address with the ability to deploy a vanity contract in a given nonce.

hey man @bokub , it's good to go now

const rlp = require('rlp');
const util = require('ethereumjs-util');

const addr = '0x6ac7ea33f8831ea9dcc53393aaa88b25a785dbf0'
const addressAsBytes = util.toBuffer(addr);

for (let nonce = 0; nonce <= 3; nonce++) {
    let calculatedAddressAsBytes = util.keccak256(util.arrToBufArr(rlp.encode([addressAsBytes, nonce]))).slice(12);
    console.log(`nonce${nonce}= "0x${calculatedAddressAsBytes.toString('hex')}"`);
}

/* Output:
nonce0= "0xcd234a471b72ba2f1ccf0a70fcaba648a5eecd8d"
nonce1= "0x343c43a37d37dff08ae8c4a11544c718abb4fcf8"
nonce2= "0xf778b86fa74e846c4f0a1fbd1335fe81c00a0c91"
nonce3= "0xfffd933a0bc612844eaf0c6fe3e5b8e9b6c1d19c"

@Siul293 hey, it's here https://github.com/9-9-9-9/Vanity-ERC20-Contract-Address-Generator

If you don't mind using a command-line tool, MyEtherWallet's VanityEth also supports contract addresses.

Great !!! Thanks
