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.

How it works
Each thread picks a random 256-bit private key k and walks k, k+1, k+2…, adding the generator point each step (much cheaper than a fresh scalar multiplication). The starting key comes from the browser CSPRNG, so the result is as random as any other key. Nothing leaves the page.
