Nostr is an open protocol for simple social posts and messaging. Your identity is a cryptographic key pair: a public key (npub) others see, and a secret key (nsec) that proves it is you.
This site never sees your secret key when you use an extension or mobile signer. With this option we generate a key pair locally and keep the secret only in your browser so you can boost and publish without installing anything.
- Next you will receive an nsec. Save it somewhere safe (password manager or offline). Treat it like a password.
- Anyone with your nsec can post as you. Never share it or paste it into untrusted sites.
- You can import the same nsec into Damus, Amethyst, Iris, or any other Nostr app—your identity moves with you.
