You can run the script with tailor made command-line arguments to outline your desired prefix, suffix, and other parameters for building vanity Ethereum addresses.
eth two 3 Pro idea: When testing the address to be sure it definitely functions, It can be sufficient to send out ETH with a testnet, such as Ropsten. No must send out serious ETH in these occasions of large gasoline selling prices.

The general public vital could be represented possibly in compressed format totaling 33 bytes in duration, or uncompressed as 64 bytes, and typically is denoted by a number one prefix 0x02 for compressed community keys, though the size with the string is a far better indicator since the prefix is not also noticeable or present dependant upon the stage and implementation.
Substitute dependencies: In combination with the open-ssl library referenced while in the article that @tayvano famous, other libraries that could be used to determine elliptic curve community addresses include the ecdsa Python library, and Bitcoin's secp256k1 library prepared in C although the latter will comprise resources for formatting bitcoin addresses that happen to be fully different than ethereum addresses as a result of formatting methods and unique hash algorithms and encoding solutions, even if the underlying private important and public crucial are the exact same, for instance. Take note: At last, it's important to get exams in position to make sure that an address generated is not only valid, but that the fundamental private critical Employed in the procedure might be legitimate to indicator transactions (i.
