How It Works
Store your most important documents in the most secure way possible - on the Ethereum blockchain.
Upload Your Document
Drag & drop your PDF will, trust, or medical directive. Maximum file size is 5MB. We support standard PDF formatting with digital signatures.
Review & Verify
Preview your document in our secure viewer. Confirm all details are correct. Our system verifies the document hasn't been tampered with using cryptographic checksums.
Generate Cryptographic Hash
We create a SHA-256 hash - a unique digital fingerprint of your document. This hash (not your actual file) is what gets recorded on the blockchain for immutability.
Pay Gas Fee & Store
Pay a small Ethereum transaction fee (gas) or use credit card via Chainlink. We record the hash on Ethereum mainnet or a compatible L2 network like Polygon.
Receive Certificate
Download your blockchain verification certificate featuring a QR code. Share this with your executor or family members as proof of authenticity.
Set Access Controls
Designate who can access your documents after your passing. You can grant access to executors, family members, or even charitable organizations.
