A self-custody dead-man's switch designed so the people operating it cannot read your secret.
ENCRYPTED ON YOUR DEVICE · VERIFIED BY ARCHITECTURE, NOT PROMISES
The problem
Every year, holders die with their keys and the assets behind them become permanently unreachable. No court order, no support ticket, no recovery phrase can reopen them.
Traditional solutions all share one flaw: someone else must hold the secret. A lawyer, a company, a safe-deposit box. Every custodian is a point of failure — and a temptation.
ProofOfLife is designed around the opposite principle: the operator is technically unable to read your secret. Not unwilling. Unable.
How it works
You write down what matters — a seed phrase, a private key, instructions. It never leaves your device unencrypted.
Your browser encrypts the secret and wraps the key for a hardware-attested enclave. The backend receives ciphertext only.
Prove you're here with one tap, or let routine wallet activity speak for you. The clock resets.
If silence stretches past your threshold, a grace window opens. Your heirs are nudged to reach you first.
Only when every condition is verified does the enclave release the secret to your heir — with a signed receipt.
Security
Not a promise — an architecture. Your secret is encrypted before leaving your device. The backend stores ciphertext. The watcher operates inside confidential computing. Release requires the configured conditions, and every release produces a verifiable receipt.
XChaCha20-Poly1305 with a fresh key per vault, sealed to the enclave's public key. Plaintext exists only in your browser's memory, briefly.
The database holds encrypted blobs and wrapped keys. A compromised server yields nothing readable — demonstrated by test, not claimed.
Decryption happens only inside hardware-attested confidential compute, only when the event chain proves the conditions were met.
Trust model
Plaintext exists in exactly two places. Everywhere else, it is ciphertext.
