Utility
Generate an Ethereum address, private key, and 12-word mnemonic locally in the browser, then back them up with QR and JSON.
Generation runs inside the browser only. Use it to create quick demo, learning, or development wallets and export only the data you actually need.
Sensitive data notice
Anyone who sees the private key or mnemonic can move assets. If you plan to hold real funds, pair this with offline storage and your own verification workflow.
Click Generate to reveal the address, private key, mnemonic, and QR backup options.
A compact checklist so first-time users can back up the account without missing the important steps.
01
Generate the address, private key, and mnemonic as one bundle and verify that the values look correct.
02
Download the private-key-free JSON backup, and scan either the address or secret QR only when needed.
03
Move sensitive data to an offline location before leaving the page, then hide or regenerate if you no longer need it visible.
The default download contains recovery metadata only and deliberately excludes the private key.
The JSON stores the address, mnemonic, derivation path, and creation time. Keep the private key outside of this file in a safer storage method if you truly need it.
