The transaction tokenizes institutional residential mortgage loans as NFTs and is set to seed a dedicated NUVA.finance vault aimed at bringing mortgage credit into DeFi at scale.
Black Lake Digital Markets and Nuva Labs said they completed the onchain minting and transfer of $25 million in institutional mortgage loans on Provenance Blockchain, describing it as the first transaction of its kind and a step toward moving originated mortgage credit into decentralized finance. The tranche is expected to seed a dedicated Black Lake vault on NUVA.finance in the coming month. Under the structure, each mortgage loan is minted as a non-fungible token on Provenance using Nuva Labs' infrastructure, while loan data is kept in a permissioned DataRoom that limits review to authorized partners. The tokenized loans are then pooled and used as collateral through NUVA's cross-chain vault system, giving depositors access to private credit yield in a permissionless, composable format while allowing holders to retain ownership of the underlying loans. Black Lake CEO and co-founder Al Qureshi said the setup uses a patent-pending verification framework with policy-hash-locked attestation and a verification toolkit for every loan token. He said investors can confirm onchain that each loan is present, eligible, and originated in compliance with the rules without viewing borrower data. Qureshi said the model addresses the opacity of traditional mortgage credit review by applying quality control across every loan in the pool rather than relying on sample-based checks. Nuva Labs CEO Anthony Moro said the structure targets inefficiencies in a U.S. residential mortgage market with more than $13 trillion in outstanding debt, where mortgage assets have been difficult to access or finance efficiently. Nuva Labs will provide the SaaS infrastructure to tokenize and manage the assets, Black Lake will act as reporting agent and initial transfer agent, and NUVA.finance will handle distribution to connect tokenized mortgage credit with onchain liquidity. June Ou, executive director of the Provenance Blockchain Foundation, said the onboarding shows the network's ability to support real assets at institutional scale. Provenance Blockchain, a Cosmos SDK-based Layer 1 (base blockchain for applications) built for financial services, has onboarded more than $23 billion in real-world assets according to Nuva Labs, while The Block's data shows more than $19 billion in the RWA (real-world asset) market domiciled on Provenance as of June 24. The chain already supports Figure Technologies' home equity loan origination business and the YLDS yield-bearing stablecoin, which the article described as the first SEC-registered instrument of its kind in the U.S. The Black Lake vault will be the first on NUVA to offer exposure to originated residential mortgage loans.
