To add additional protection against typos or transcription errors, Base58Check is a Base58 with built — in error checking code.
Bitcoin vanity address starts from 1 and your desired part. Other parts consist of random digits, uppercase, and lowercase letters. The exception are the uppercase letter "O", the number "0", uppercase letter "I"(i), lowercase letter "l"(L), are never used to prevent visual ambiguity.
Security is our top priority. After the address generation is complete we send it to you with the chosen delivery method. Our automatic process deletes every trace of generation.
Most Bitcoin vanity addresses are 34 characters. Some Bitcoin addresses can be shorter than 34 characters (as few as 27 in theory) and still be valid. A significant percentage of Bitcoin addresses are only 33 characters, and some addresses may be even shorter. These shorter addresses are valid simply because they stand for numbers that happen to start with zeroes, and when the zeroes are omitted, the encoded address gets shorter.
