The existing ones — <a href="https://github.com/alpyxn/aeterna">Aeterna</a>, <a href="https://github.com/giovantenne/lastsignal">LastSignal</a> — require periodic manual check-ins. That works. But Nostr already has a better signal: every post, reaction, zap, and repost is a cryptographically signed event tied to your public key. Your normal usage is proof of life.</p> <p>I built <a href="https://github.com/AusDavo/nostr-dead-man-switch">nostr-dead-man-switch</a> to use that signal. It subscribes to relays, watches for any event from my npub, and resets its timer on activity. If I go quiet for long enough and don&rsquo;t respond to warning DMs, it fires off emails, webhooks, or Nostr notes to the people who need to know.</p>
