Vanity Address Generator · Sonic
Vanity Address Generator searches locally for EVM addresses with a custom hex prefix or suffix on ETH, BSC, Arbitrum. Multi-threaded; keys stay on-device.
Calculations and checks on this page run in your browser. Private keys and seed phrases are never uploaded to the server.
About this tool
Vanity Address Generator finds EVM wallet addresses whose 40 hex characters after 0x match a chosen prefix or suffix (for example 0x8888… or …6666). Vanity improves recognition and display; it does not increase cryptographic strength.
After you pick a network, the tool brute-forces random private keys locally until the address matches. EVM address format is shared across ETH, BSC, Arbitrum, Polygon and similar chains. Web Workers use available CPU cores; private keys are not sent to a server.
Difficulty grows roughly as powers of 16 with each extra character: about four hex digits often finish in seconds, six may take minutes, and eight or more can take hours.
How to use
- Select the target EVM network on the left (for example ETH or BSC).
- Enter a prefix and/or suffix using only 0–9 and a–f.
- Enable case-sensitive matching if you need an EIP-55 checksum match (much harder).
- Start the search; when a match appears, copy the private key and store it offline.
FAQ
Is an Ethereum vanity address as safe as a normal one?
Yes, if the private key comes from cryptographically secure randomness. This tool uses crypto.getRandomValues, not a predictable seed. Avoid historical tools with weak RNG (such as the 2022 Profanity incident).
Why is my vanity address taking so long to generate?
Search space grows exponentially; each extra hex digit multiplies expected attempts by about 16. Keep prefix plus suffix to six characters or fewer, or run on a stronger machine.
Can a vanity address include letters like g or o?
No. EVM addresses are hexadecimal: only 0–9 and a–f (case matters under checksum matching).
How do I avoid address-poisoning lookalikes?
Attackers craft addresses that share the first and last characters of ones you use. Verify every character before sending; do not rely on truncated history or partial copies.
