Factflew Reviews & Product Details

Factflew is a digital file certification SaaS built on the Polygon blockchain. It introduces a unique "Unknow Your Customer" (UYC) architecture to secure digital timestamps completely anonymously. All SHA-256 cryptographic hashes are computed locally on the user's device via the Web Crypto API, ensuring that sensitive documents and raw files never leave their possession. Factflew issues instant digital certificates via a Progressive Web App (PWA) with zero collection of names, emails, or phone numbers. Device authorization is handled entirely through a technical FF-code system, creating a new standard for decentralized data integrity and absolute user privacy.
