Cipherwill

People hold their entire lives in digital form (crypto wallets, password managers, cloud storage, accounts) but have no plan for what happens to that access when they die or become incapacitated. Paper wills have no real-time triggers and cannot click through 2FA, while password managers lock everything behind a master passcode that grieving families do not know. The page cites $140+ billion in stranded crypto assets, 2.4 million accounts permanently locked annually, and families spending 15-30 hours dealing with platforms and lawyers to retrieve keys. Without a plan, families face locked devices, interrupted subscriptions, lost memories, and unreachable assets.

Cipherwill is a zero-custody, end-to-end encrypted dead man's switch that stores passwords, seed phrases, private keys, documents, notes, and financial credentials, encrypting everything client-side in the browser with AES-256-GCM before upload so the company itself cannot read the contents. It uses a cascade of encryption layers: symmetric AES-256-GCM sealing, asymmetric ECDH (SECP256K1) key exchange targeted to a specific beneficiary, and a time-release gate, all of which must clear sequentially before data unlocks. A multi-channel heartbeat system monitors login activity on a chosen interval (default 3 months), sending check-in notices and heightened alerts over a roughly 100-day silence window before releasing pre-sharded decryption keys to beneficiaries. Users can tailor setups for passwords, finances, memories, business operations, or creator assets, and the company states its cryptographic protocols and client-side libraries are open source and independently audited.
