bug bounty android beta

Find a bug.
Earn 10,000 sats.

Cairn's in beta, and the only way it gets solid is people kicking the tyres. Break it, tell us exactly how to reproduce it, and there's 10,000 sats in it for every confirmed bug — paid straight to your Lightning address.

10,000 sats per confirmed, reproducible bug · paid over Lightning
Find it in the app under More → About. Pre-filled with the current release.
Tip: number your steps. “1. Open the price widget. 2. Rotate the phone. 3. Widget goes blank.”
Add a screenshot
Paste with Ctrl/⌘ + V, drag an image in, or click to choose
Up to 4 images · PNG, JPEG, WebP or GIF · 6 MB each. Optional, but a screenshot of the bug helps enormously.
A Lightning address (you@wallet.com) or an LNURL. This is the only thing we’ll send the sats to, so double-check it.

Report received.

Thanks for the catch. If it checks out, the 10,000 sats are on their way to .

Confirmed reports are usually paid within a few days.

Report another bug
The fine print, plainly:
  • 10,000 sats per confirmed, reproducible bug we didn’t already know about.
  • First valid report of a given bug wins it. Duplicates and already-tracked issues aren’t paid.
  • Crashes, wrong data, broken widgets, layout breakage — all fair game. “I’d prefer it differently” isn’t a bug.
  • Paid after triage, over Lightning, to the address you give. Get it right.
  • Your report and screenshots are emailed to the maintainer and nothing else. No account, no tracking.
