Behind the scenes, your documents are hashed and recorded on Polygon — a public, energy-efficient network with permanent, read-only records. We don't move your funds, we don't see your documents, and your private key is protected on your device. PRIVACY BY DESIGN Document hashing happens on your device Wallet keys are stored & protected in iOS Keychain. External wallets supported via WalletConnect (Rabby, MetaMask & more) WHY BLOCKCHAIN? Traditional records depend on filing cabinets and the companies maintaining them. E-signature platforms depend on a single vendor staying in business. Blockchain doesn't depend on either. Your record lives on a public, immutable ledger — verifiable by anyone, forever, even if chainSign itself disappears tomorrow. IMPORTANT chainSign is a blockchain timestamping and document-verification tool. It is not a notary public service and does not perform legally recognized notarization. chainSign records do not constitute legal proof, legal authentication, or admissible evidence in any jurisdiction. Users requiring notarization or formal legal authentication should consult a licensed professional in their jurisdiction. — Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period.
