Key Generation

A Bitcoin private key is just 256 random bits. Everything else — the public key, the address — is derived deterministically. Watch it happen, in your browser.

⚠ Educational demo

Do NOT send real Bitcoin to any address generated here. The private key was generated in your browser and never transmitted, but it's also displayed openly on the page. Anyone looking over your shoulder, screen-recording, or reading your browser history can take ownership of any funds at this address. This page exists to show you what a Bitcoin key actually is — not to be a wallet.
