eClosing and eVaulting (ProvenDB)
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).

Quarter Homes is a real estate technology company that modernizes vacation home ownership through a fractional, co-ownership model. It aims to make owning a second home more accessible and affordable by allowing up to four parties to collectively purchase and own a property. Quarter Homes manages the entire lifecycle of the property, including all legal, financial, and property management complexities, to provide a seamless, hassle-free experience.
The company’s innovative model incorporates the Hedera blockchain network, which underpins its operational framework. For each property, a unique LLC is established, and the legal ownership interest is divided into fractions represented as non-fungible tokens (NFTs) on the Hedera Token Service (HTS). This provides each owner with a verifiable, digital proof of ownership.
Quarter Homes leverages the Hedera Consensus Service (HCS) to create a transparent and immutable log of all activities associated with the property. This includes governance, maintenance activities and scheduling, ensuring all parties have a trusted and shared view of the property's status and history.
