Encrypted Wills & Dead Man's Switch
Securely store sensitive messages or wills, anchored to Bitcoin for tamper-proof integrity. Designate beneficiaries and ensure your wishes are delivered only when the time is right.
Create Encrypted WillHow It Works
1. Encrypt Your Message
Write your will or message. Our client-side encryption ensures only you and your designated attorney can access the content.
2. Anchor to Bitcoin
A hash of your encrypted content is embedded in a Bitcoin transaction, providing immutable proof of its existence at a specific point in time.
3. Designate Recipients
Assign an attorney to manage access and beneficiaries to receive the message. Your attorney checks in every 90 days to confirm the testator is alive. After 2 missed check-ins, beneficiaries are automatically notified.
Dead Man's Switch
If the attorney fails to check in for two consecutive 90-day periods, the system automatically notifies beneficiaries with instructions to access the content. An emergency release code is also provided at creation — allowing the testator to release immediately if needed.
Secure Key Splitting
Encryption keys are split between the attorney's passphrase and on-chain data, ensuring no unauthorized party can access the content. Attorneys can transfer custody to a successor if needed.
Emergency Release
The testator receives an emergency release code at creation. Submitting this code immediately delivers the will to all beneficiaries — no attorney check-in required.
