A classy Nostr keystore, NIP-07 signer, and Lightning wallet that lives in your browser sidebar. πΈ
Open source and private by design.
Install the extension for Chrome (and Chromium browsers) at: https://sidecar.top
Sidecar 1.3.0 is live in the Chrome Web Store. π©
This one is all about keeping your keys safe and knowing exactly what you're signing.
π§³ Full vault backup. Export every account and wallet connection into a single password-encrypted file, and restore it on another device. Your whole setup travels with you.
π Smarter backups for single keys too: NIP-49 (ncryptsec) import and export, plus scannable QR codes that hide themselves on a countdown.
π· A clearer signing prompt. Events are labeled in plain language, and anything unusual gets a heads-up before you approve it.
π€Ό Multi-account safety. On sites where you've signed in with more than one account, every post confirms who's posting. No client can silently sign as the wrong key.
πͺ Spend limits for the wallet: a rolling daily cap on auto-zaps, so a connected site can't drain anything, even one small zap at a time.
π And a built-in Help & Guides page, one click from the top bar, if you're new to any of this.
Update rolls out automatically. Your keys, your identity. π
Stay classy, Nostr. πΈ


A Classy Nostr Signer β Sidecar
A NIP-07 Nostr signer with a built-in Lightning wallet, in your browser's side panel.
Where do your keys actually live when you use Sidecar? π
Sidecar never sends your keys anywhere. They're stored on your device, encrypted, and the key that unlocks them is derived from the PIN you chose. We couldn't recover it if we wanted to, and that's the point: nothing to breach and no one between you and your identity.
The elegant part of that design is also the honest part: it means the responsibility is genuinely yours.
Two small habits make it effortless:
Back up your keys. Export your nsec, an ncryptsec, or a full encrypted vault, and keep it somewhere outside your browser. A backed-up key can rebuild everything, anywhere.
Keep your PIN somewhere private. A password manager or a piece of paper in a safe place. There is no "forgot my PIN" feature, by design.
Self-custody isn't a feature we added. It's the whole idea.
Stay classy, Nostr. πΈ
