Vanity-ETH is an open source tool using your web browser to generate Ethereum vanity addresses.
Enter a short prefix/suffix of your choice, and click ‘generate’ to start.

Random Ethereum Private Keys Random Bitcoin, Ethereum, Litecoin, Dogecoin private key generator. Generate a random private keys in WIF, hex or decimal formats. To create a binary seed from the mnemonic, we use the PBKDF2 function with a mnemonic sentence (in UTF-8 NFKD) used as the password and the string 'mnemonic' + passphrase (again in UTF-8 NFKD) used as the salt. The iteration count is set to 2048 and HMAC-SHA512 is used as the pseudo-random function. The seed phrase is able to generate private keys for every address you have, so you’ll be able to back up all your accounts with one seed. How to store mnemonic seed and private keys Good Practice. Store private keys and seed offline to avoid the risk of hacking, information leakage or equipment fault. BIP 39 describes the implementation of a mnemonic code or mnemonic sentence - a group of easy to remember words - for the generation of deterministic wallets. Bitcoin private key is not stored in this way, rather seed to prng which generated the private and public key pair is converted into mnemonic so that its easy for human to type or remember.

What's a vanity address?

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

How it works

Enter the prefix/suffix of your choice, and click ‘generate’ to start. Your browser will generate lots of random addresses until one matches your input.
Once an address is found, you can reveal the private key, or click the 'save' button to download a password-encrypted keystore file.
You can increase the number of working threads to reach higher speeds, or decrease it if you computer struggles.

Security

As explained above, everything is computed only in your browser. Nothing ever leaves your machine, or even your browser tab. There is no database, no server-side code. Everything vanishes when you close your tab.
Vanity-ETH cannot and will never store your private key, and if you don't trust it, you have 3 ways to ensure your key remains private:
- Once the web page is loaded, you can turn off the internet and continue playing, it will work seamlessly
- You can also download the latest build of Vanity-ETH here and use it on a completely offline computer
- The code is 100% open source and available on Github. You can review it as much as you want before using it
Vanity-ETH uses a cryptographically secure pseudorandom number generator (CSPRNG) to generate Ethereum addresses.
The keystore file is encrypted with a AES-128-CTR cipher using the BKDF2-SHA256 derivation function with 65536 hashing rounds.

Performance

For some reason, the performance of Vanity-ETH can vary a lot from a browser to another. Currently, Chrome provides the best results.
Using Vanity-ETH on your phone or tablet will work, but don't expect to reach the speed of a good old computer.

Compatibility

Any address generated with Vanity-ETH is ERC-20 compatible, which means you can use it for an ICO, an airdrop, or just to withdraw your funds from an exchange.
The keystore file is 100% compatible with MyEtherWallet, MetaMask, Mist, and geth.
