Lost bitcoin and assets
Your crypto savings, exchange accounts and digital investments become out of reach for your family if they don't know the seed phrases and passwords. Neither banks nor blockchains return assets without the keys.
01The risk
Digital death is a real risk to your assets
The modern world runs on passwords and keys. Every year, millions of dollars in crypto and priceless digital archives vanish forever along with their owners.
Unsaid words and secrets
We often put off difficult conversations or avoid talking about death with the people we love. But leaving them in the dark, with a pile of unresolved digital obligations, is a burden they don't need.
02How it works
A Dead Man's Switch with safeguards
No daily check-ins: while your payment goes through, the system stays quiet. A single failure triggers nothing.
01
Encrypted in your browser
You write a separate message for each recipient (up to 5). Your browser encrypts the text (AES-256) before sending — the server only ever receives ciphertext.
02
Payment as a signal
Your monthly payment ($2) is your “I'm here” signal. As long as it goes through, the system does nothing.
03
Check-in and delivery
If payment stops, we email you on day 3, 7 and 25 — and from day 25, your trusted person too. No response within 30 days — after a manual review, each recipient gets their own secure link.
What happens if payment stops
- Day 0
A payment fails. Nothing happens — the card may simply have expired.
- Day 3 · 7 · 25
Three emails with an “I'm here” button. One click and everything stops.
- Day 25 · 28
We write to your trusted person and, if they don't reply, we call. They can confirm you're okay.
- Day 30
No response — after a manual review, each recipient gets their own link and opens their message.
