OneSpan is a Web3 platform that offers a dedicated eClosing solution designed to digitize and secure the entire lifecycle of high-value digital agreements, particularly in the mortgage and lending industries. The platform streamlines the closing process by enabling remote online notarization (RON), electronic signatures, and identity verification, all within a secure and compliant digital environment. A central component of this solution is the OneSpan eVault, a specialized repository for managing the authoritative copy of critical digital documents, such as promissory notes (eNotes).
To provide an unparalleled level of trust and auditability, OneSpan has integrated its platform with ProvenDB, a data integrity service built on the Hedera network. When a document is signed or a key milestone is reached in the eClosing process, a cryptographic fingerprint (hash) of the agreement is anchored to the Hedera public ledger. This action, facilitated by ProvenDB, creates a permanent and immutable timestamped record on the Hedera Consensus Service (HCS).
