1.0.0

First release. A small NIP-07 Nostr signer for Safari, Chrome, Brave, Edge and Arc.

No analytics, no accounts, no network requests of any kind. Your key is encrypted at
rest as a NIP-49 ncryptsec — a standard format, so the same string works with nak and
other NIP-49 tools.

Install

Safari (macOS): download mineracks-signer-1.0.0-safari-macos.zip, unzip, drag the app
to /Applications, launch it once, fully quit Safari (⌘Q) and reopen, then
Safari → Settings → Extensions → enable mineracks signer → set website access to Allow.
The app is signed with a Developer ID and notarized by Apple — Safari will not list an
extension whose containing app isn't.

Chrome / Brave / Edge / Arc: download mineracks-signer-1.0.0-chrome.zip, unzip, then
Extensions → Manage Extensions → Developer mode → Load unpacked → select the folder.

Verify what you downloaded against SHA256SUMS.txt.

Then

Click the ⚡ icon, paste your nsec (or a hex key, or an existing ncryptsec), set a
password. Check the npub it shows is the one you expect.

Notes

Tested end to end on Chromium by an automated suite (16 checks) and by hand on Safari 26.
No independent security audit — it's deliberately small enough to read yourself, and
you should before trusting it with a key that holds value.

The README documents eight gotchas that cost us real time; most apply to any Safari web
extension, not just this one.
