Sidecar
Creator of Sidecar — a classy Nostr signer with a built-in Lightning wallet, in your browser's side panel.
Sidecar is a NIP-07 Nostr signing extension that lives in your browser's side panel. It holds your keys locally, encrypted behind a PIN, and provides window.nostr to the web apps you use, so you can sign in and sign events across Nostr clients without ever pasting your nsec into a website. It also has a built-in Lightning wallet (Nostr Wallet Connect) and a composer for posting notes directly from the panel.
