About vanity address
A vanity address is found by generating keys at random until one starts or ends with the characters you want. Each additional character multiplies the work by sixteen, so four is quick, five is slow, and six is impractical in a browser tab. Everything here happens locally using the operating system's secure random generator, and the key is never transmitted. The cautionary tale is Profanity, a popular desktop generator whose randomness was weak enough that every address it produced could be reverse-engineered — millions were drained from wallets that appeared entirely safe.
Common questions
How do vanity Ethereum addresses work?
By grinding private keys until the derived address matches a hex prefix you chose. Harder prefixes take exponentially longer. This page runs that search in your browser so the key never has to leave the tab.
Are keys generated here uploaded anywhere?
No. Generation and matching happen in this tab. Closing the tab discards anything you did not copy yourself. If a page asks you to paste a seed phrase to save a vanity address, treat that page as hostile.
Why is a long prefix so slow?
Each extra hex character multiplies the search space by sixteen. A two-character prefix is quick; six or more can take a long time on a laptop. That cost is mathematical, not a setting this page can waive.
