Did you know bitcoin wallets can have fallback keys that only become active after some time? How that works, other use cases, and more are explained in the new Custom spending conditions page. Big thanks to @npub1aa0j...6zud for putting it all together. Next on Michael's to-do list is a follow-up page that dives into UX best practices for this functionality. Stay tuned. For now, we'd love to get your feedback on the new page.
