Frequently Asked Questions

A vanity Ethereum address is a custom cryptocurrency wallet address that contains specific characters or patterns you choose. For example, instead of a random address like 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb, you could have 0x000000dead or 0xABCdef123. It's purely cosmetic but makes your address memorable and personalized.

Our generator uses optimized client-side code (WebAssembly) to rapidly generate and test Ethereum addresses directly in your browser until it finds one matching your desired pattern. The process is completely safe - you receive both the address and its corresponding private key without it ever leaving your device.

Yes! Our vanity address generator is completely free for all supported patterns. Since it runs on your own device, there are no server costs for us to pass on to you.

Generation time depends on your pattern length and device speed: 1-5 characters are usually instant, while 6-7 characters might take a few minutes. Each additional character increases difficulty by 16x.

Yes, when generated correctly. Our tool uses profanity2, which is specifically designed to be cryptographically secure. Unlike the original profanity tool (which had a critical vulnerability), profanity2 uses proper entropy and is considered safe by security researchers. Your private key is generated securely and only you have access to it.

Absolutely. The private keys are generated using cryptographically secure methods and are never stored on our servers. They're displayed only once to you, and we have no way to access them after generation. Always verify your address in a wallet before sending funds, as with any address.

Profanity (original) had a critical security flaw in its random number generation that allowed attackers to recover private keys. Profanity2 was created by 1inch Network to fix this vulnerability. It uses a seed-based approach where you provide initial entropy, making it impossible to reverse-engineer private keys. Our tool uses profanity2 exclusively.

Yes! Always import your private key into a trusted wallet (like MetaMask or Ledger) and verify that it generates the same address before sending any funds. This is a best practice for any wallet, not just vanity addresses.

Ethereum addresses use hexadecimal characters: 0-9 and a-f (or A-F). You can create patterns with any combination of these 16 characters. Note that addresses are case-insensitive by default, but you can enable case-sensitive mode for more specific patterns (which takes longer to generate).

Currently, our generator supports either a prefix OR a suffix per generation, not both simultaneously. This is because generating both would increase difficulty exponentially. You can choose prefix mode or suffix mode before generating.

We support patterns up to 7 characters. Longer patterns become exponentially harder to generate - an 8-character pattern could take hours or days even with powerful GPUs. If you need longer patterns, consider using multiple shorter patterns or contact us for custom enterprise solutions.

Our optimized client-side generator uses your browser's capabilities to check millions of addresses per second. It is significantly faster than standard CPU-based tools thanks to WebAssembly optimization.

Vanity addresses are useful for: 1) Personal branding - making your address memorable, 2) Business use - addresses matching your company name, 3) Donations - easier for people to recognize and remember, 4) Gift addresses - creating special addresses as gifts, 5) Marketing - addresses that stand out in transaction lists.

Yes! Vanity addresses work just like regular Ethereum addresses. You can deploy smart contracts from them, receive NFTs, interact with DeFi protocols, or use them as multisig wallets. There's no functional difference from random addresses.

Common patterns include: Numbers (0x000000, 0x111111, 0x123456), Words (0xdead, 0xbeef, 0xcafe), Names (0xalice, 0xbob42), Brands (0xdeFi, 0xNFT), Dates (0x2024, 0x0101), and Emoji-like (0xface, 0xc0de). The most expensive vanity address ever sold was reportedly worth over $1 million!

Yes, by transferring the private key. However, this is generally NOT recommended for security reasons. Once someone else has your private key, they have full control of the address forever. It's better to generate a new vanity address for the recipient.

Generation time is probabilistic - you might get lucky and find a match quickly, or it might take longer. The estimated times are averages. Also, during high traffic periods, there might be a short queue. If it's taking significantly longer than estimated, try refreshing the page or contact support.

Unfortunately, if you lose your private key, there's no way to recover access to that address. Ethereum addresses are secured by cryptography - no one, including us, can help you recover a lost private key. Always save your private key securely in multiple locations (password manager, encrypted backup, etc.).

We use Cloudflare Turnstile to prevent bot abuse and protect our GPU resources. Simply wait a moment for the invisible verification to complete, then try again. If the issue persists, try refreshing the page or clearing your browser cache.

Yes! Our generator works on all devices including smartphones and tablets. The generation happens locally in your browser. Just make sure to safely save your private key after generation.

No, never. Private keys are generated on-demand and displayed only to you. They're never logged, stored, or transmitted to our databases. Once you close the page, the key is gone from our systems forever.

We collect minimal analytics: generation patterns (e.g., '5 characters'), generation times, and general location (country level) for service optimization. We never collect private keys, addresses generated, or personally identifiable information unless you voluntarily contact us.

Yes! Our entire codebase is open source and available on GitHub. You can review the code, verify the security measures, and even run your own instance if desired. We believe in transparency for security-critical tools.
