Vanity Contract Address about vanity-eth

[0xjluis]

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.

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

[9-9-9-9]

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

@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.

[9-9-9-9]

@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?

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"

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

Great !!! Thanks
