Plan demo Prototype

Set up a check-in plan the way the real service is meant to work: who your heirs are, how often you check in, how the warnings escalate, and a locked letter whose passphrase is split so that no single person can open it. It all happens in this browser tab. Nothing is sent, saved on a server, or emailed.

Do NOT type a seed phrase, private key, or wallet password anywhere on this page.That is good practice on any web page. This site never holds, moves or sees your crypto, keys or seed phrase, and this demo only shows how the flow works, so use made-up text. It has not had an independent security review.

1. Your heirs

Heir names (one per line, up to 8)

2. Check-ins and escalation

Check in every (days)

Second reminder (days after a miss)

Trusted-contact notice (days after a miss)

Grace period before release (days after a miss)

Order of events after a missed check-in: reminder on day 0, second reminder, a trusted person is asked to confirm you're okay, and only at the end of the grace period is the locked letter released. You can cancel at every step before release.

3. Your letter of instruction

Letter (where things are and what to do. No secrets.)

4. Lock it and split the key

Passphrase for the locked letter Make a strong random passphrase for me (recommended) I'll choose my own

Shares needed to open (k)

Total shares (n)

The passphrase is never given to anyone whole. It is cut into n shares, and any k of them put it back together. Fewer than k reveal nothing.

Your plan settings (not the letter or shares) are passed to the simulator in the page link and kept in this tab only. Nothing is stored on a server.

What the real service would add

Real email and text reminders, one-tap check-ins, trusted-contact confirmation, and the actual delivery of the locked letter to your heirs. None of that exists yet. See Trust the code for exactly what this prototype does.
