Is it possible that an Ethereum Address starts with a 0 on the first place after the hex prefix?

For example: 0x0c01a1da70b4109be8789af5fd678183145dbe55

    Yes, it is possible. – goodvibration Apr 10 '20 at 9:13
  • It's not only possible, it is true by the definition of an Ethereum Address, which yields the set of all hexadecimal strings of 40 characters (except for the string which is all zeros). – goodvibration Apr 10 '20 at 9:33
  • So technically speaking, you can have as many leading zeros as you want, up to 39 of them. You might have a hard time finding the private key of each one of them, nevertheless, they will all be valid Ethereum addresses. – goodvibration Apr 10 '20 at 9:34



YOu can choose the prefix or suffix and they are called vanity addresses

A vanity address is an address which part of it is chosen by yourself, making it look less random. Examples: 0xc0ffee254729296a45a3885639AC7E10F9d54979, or 0x999999cf1046e68e36E1aA2E0E07105eDDD1f08E
