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).

Tolam Earth is a Web3 marketplace and data utility platform engineered to enhance the efficiency, transparency, and credibility of the Voluntary Carbon Market (VCM). Launched as a joint venture with backing from the HBAR Foundation, Tata Consultancy Services (TCS), and Object Computing, Tolam directly addresses critical market challenges such as price opacity, illiquidity, and concerns over the integrity of carbon credits.
Built on the Hedera network, the platform provides a marketplace for corporate buyers and carbon project developers to transact in Digital Environmental Assets (DEAs). It leverages the Hedera Token Service (HTS) to represent carbon credits as unique tokens and the Hedera Consensus Service (HCS) to create a publicly verifiable and immutable audit trail for all transactions and credit retirements. This ensures a high degree of trust and transparency for all participants.
A core component of the platform is its "mitigation engine," which employs sophisticated matching algorithms. This engine helps corporate buyers discover and purchase carbon offsets that align precisely with their specific Environmental, Social, and Governance (ESG) goals, considering factors like project type, geographical location, and additional community or biodiversity co-benefits.
