Complete Guide to
Vanity Addresses

Everything you need to know about generating, securing, and using custom Ethereum addresses

Table of Contents

1. What is a Vanity Address?

A vanity Ethereum address is a custom cryptocurrency wallet address that contains specific characters or patterns you choose. Instead of using a completely random address assigned by your wallet, you can create one that's memorable, branded, or meaningful to you.

Regular Ethereum Address:

0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb

Vanity Address Example:

0x00000035Cc6634C0532925a3b844Bc9e759

The custom part can be at the beginning (prefix) or end (suffix) of your address. While it's purely cosmetic and doesn't affect the address's functionality, it makes your address stand out and easier to remember.

Key Facts

  • ✅ Fully functional Ethereum addresses
  • ✅ Compatible with all wallets and dApps
  • ✅ Same security as regular addresses (when generated properly)
  • ✅ Can be used for smart contracts, NFTs, DeFi, etc.
  • ✅ You control the private key just like any address

2. Why Use Vanity Addresses?

🎨 Personal Branding

Create addresses that match your username, brand, or identity. Perfect for influencers and content creators.

🏢 Business Use

Companies can use addresses matching their name for easy recognition in transactions.

💰 Donations

Make your donation address memorable and easy to verify for supporters.

🎁 Gifts

Create special addresses as unique gifts with personal meaning.

🔍 Easy Verification

Quickly spot your address in transaction lists and block explorers.

💎 Collectible Value

Rare patterns can have actual market value - some sold for $1M+!

3. How Generation Works

Generating a vanity address involves repeatedly creating random Ethereum addresses until one matches your desired pattern. Here's the technical process:

1

Generate Random Private Key

Create a cryptographically secure random 256-bit number using proper entropy sources.

2

Derive Public Key

Use elliptic curve cryptography (secp256k1) to generate the corresponding public key.

3

Generate Address

Hash the public key using Keccak-256 and take the last 20 bytes to create the Ethereum address.

4

Check Pattern Match

Compare the generated address with your desired pattern. If it matches, we're done! If not, repeat from step 1.

⚡ Optimized Performance

Our service uses optimized WebAssembly (WASM) modules to speed up this process directly in your browser:

  • 🖥️ Standard: ~1000 addresses/second
  • 🚀 Optimized: ~500,000+ addresses/second
  • 📈 Speedup: 500x faster

4. Security Considerations

Critical Security Information

  • ⚠️ Always verify your private key in a trusted wallet before sending funds
  • ⚠️ Never share your private key with anyone - not even "support"
  • ⚠️ Save your private key in multiple secure locations immediately
  • ⚠️ Use only trusted, open-source vanity generators (like ours!)

All code is publicly auditable on GitHub. No hidden backdoors.

Profanity2

Uses the secure, vetted profanity2 algorithm by 1inch Network.

No Storage

Private keys are never logged, stored, or transmitted to databases.

Proper Entropy

Uses cryptographically secure random number generation.
