Wallet Generator

Generate private keys or BIP-39 mnemonics and derive HD accounts — never leaves your browser.

works offline handles secrets
You are online
Keys and mnemonics are generated and processed only in this browser tab; nothing is sent anywhere, nothing is stored, and the page has no analytics. You may want to turn off the internet before using this tool: the site caches itself on first visit, so this page keeps working offline. For wallets that will hold real funds: go offline, generate, write the secret down on paper, then close the tab. Prefer a hardware wallet for anything serious. Anything you copy can be read by other apps with clipboard access.

Entropy comes from crypto.getRandomValues (the browser's CSPRNG). Mnemonics are BIP-39 (English); accounts are derived with BIP-32/44 exactly like MetaMask, Ledger and every other standard wallet.
