Dead man's switch for your cold wallet assets

What it does

Dead man's switch for your crypto cold wallet. Set it up once: add your heir's email, record where your seed phrase is stored, then check in every 30 days. Miss the window? There's a 7-day grace period. Still no response — the inheritance email sends automatically with a full cold wallet recovery guide attached. No seed phrases ever stored on our servers. One-time payment, no subscription — if you're gone, who's going to renew it?

But instead of 16 digits (53 bits of entropy), we generate 12 random words from the Monero wordlist (128 bits) and derive the account identifier+"password" using libsodium. The app is built on top of our existing Flare code and infrastructure. It uses SvelteKit, Shadcn, Tailwind CSS on the frontend, and FastAPI, SQLAlchemy, Celery on the backend. It’s hosted on Hetzner and uses Scaleway for sending…

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
