Vanity ETH GPU

A fast Ethereum vanity address generator that runs entirely in your browser.

Features

• Multi-threaded - Uses Web Workers for parallel address generation
• Privacy First - All computations run locally in your browser, no server communication
• Custom Prefix/Suffix - Find addresses starting or ending with your desired characters
• Wallet + First Contract Targets - Scan either the wallet address or its first CREATE deploy address (nonce 0)
• Keystore Export - Download encrypted keystore JSON files

Requirements

• A modern browser (Chrome, Firefox, Edge, Safari)

Usage

1. Choose target: wallet address or first contract address.
2. Enter your desired prefix and/or suffix (hex characters: 0-9, a-f).
3. Click Generate and wait for a match.
4. Confirm the result shows the local verification badge.
5. Reveal the private key or download an encrypted keystore.

Contract target caveat

The contract target is specifically the first CREATE deployment address at nonce 0 for the generated deployer wallet. If that wallet sends any other transaction first, the first-contract address changes.

Security

• All scanning runs locally in your browser.
• Disconnect from the internet after the page loads for maximum security.
• Never share your private key.
• The UI re-derives the wallet/target address from the private key before display/export.
• Impossible or contradictory prefix/suffix combinations are blocked before generation starts.
