Contract bytecode

Paste the contract's Deployment bytecode (creation code, not runtime code): 0x-prefixed hex. If it takes constructor arguments, append them to the end.

Vanity rules

You can use a prefix and a suffix together. "Contains" only requires the string to appear somewhere — much faster to hit, but the address isn't unique. This rule needs about 65,536 attempts on average.

Addresses are derived from this site's token factory: BNB Chain is 0x5dA02b46A87111AddBfcAd2729458622B96035DE, i.e. keccak256(0xff ++ factory address ++ salt ++ keccak256(bytecode))。
