you just made a hard choice. thinking about what happens "after" isn't exactly fun. but the fact that you're here means you deeply care about someone and you want to protect them no matter what. that’s a powerful thing, and it deserves more than a form letter.
-
-
in a digital world that's getting colder by the second, i wanted to give you something "handmade." since my actual drawing skills stopped improving in kindergarten, i used a specialized ai to help me create a "photo" of a crayon drawing i made while thinking about this project. it’s imperfect, it's a bit silly, but it’s real to me.

-

i want you to know that on the other side of this complex math is a real person who understands the weight of what you're setting up. i don't take that trust lightly.

take a breath. your family is safe now. there’s no rush to do anything else right now. just keep your shard a safe, and make sure your beneficiary has shard b.

one critical thing: to make sure you're still with us, we need a "heartbeat." click the link below once just to verify you can access it. it resets your 90-day timer.
-
-
verify my heartbeat & reset timer
-
-
pro tip: set a reminder so you don't forget. add a reminder to my google calendar (for 30 days from now).

this is my personal email. if you have a question, a fear, or just want to tell me how your setup went, just reply. i read them. i answer them.

deeply grateful you're here,

hey,
- it's been 30 days since we last heard from you. i'm just checking in to make sure everything is okay.
- could you click the link below? it just tells our system you're still with us and resets your timer. it takes two seconds.
-
- i'm still here
-
- pro tip: if you're busy now, add a reminder to your calendar for tomorrow so you don't forget.
- add reminder for tomorrow
-
- if you don't click it, no big deal for now. i'll check in again in another 30 days. but after 90 days of silence, we'll have to send shard c to your beneficiary.

- a message from Deadhand.
-
- hello,
- i'm writing to you because 90 days ago, {user.email} entrusted our system to reach out to you if we stopped hearing from them.
-
- we haven't received a heartbeat check-in from them in three months. as per their explicit instructions, i am now releasing the final piece of their digital legacy to you.
-
- this is shard c. it's one of three pieces needed to access their crypto assets. if they followed our setup guide, you should already have shard b (likely a printed document or a digital file they gave you).
-
-
- shard c value:
- {shard_c_value}
-
-
-
-
how to use this:
-
- - locate shard b (the one they gave you).
- - go to deadhandprotocol.com/recover.
- - enter both shard b and shard c into the tool.
- - the tool will reconstruct their original seed phrase for you.
-
-
my deepest condolences for whatever situation has led to this email. i built Deadhand specifically so that people wouldn't have to worry about their loved ones being locked out of their hard-earned assets during difficult times.
-
- i hope this tool helps you in some small way.
-
- with respect,
- deadhand protocol

protect your own legacy

you've just seen how Deadhand works. if you have crypto, don't leave your family in the dark. set up your own trustless switch in 5 minutes.
