Proved Borrowing Base: zero-knowledge checks of fintech loan-tape reports

I found no company offering zero-knowledge borrowing-base certificates or ZK checks of fintech loan tapes for private-credit warehouse lenders. The ZK lending work I found is mostly consumer credit scores, DeFi collateral and hackathon projects (Midnight, zkVerify/Stormbit, ETHGlobal showcases), plus crypto-native borrower reporting like Credora and Accountable. None of it targets institutional warehouse lines. The real competition is the current setup. Cascade, dv01, Arcesium, ABLSoft, Situs and Street Solutions already automate borrowing-base calculations, with either the lender or a trusted platform seeing the full tape. Cascade's contract library of eligibility definitions is the closest thing to the criteria compiler. The biggest risk is demand, not competitors. Warehouse lenders usually have a contractual right to the full loan tape and want it for audits, haircuts and enforcement. They may not pay to see less data. The privacy argument may matter more to borrowers, who want to keep borrower PII or strategy away from lenders, especially lenders who also compete with them. A proof also only shows that the code ran on the committed tape. It does not show that the tape matches reality: servicer records, bank cash and the loans themselves. That attestation link is where dv01 already sells "real consumer" checks. A new entrant has the best chance in two cases. The first is anchoring the commitment to servicer or bank data (for example via zkTLS), so the proof covers whether the tape is real, which today's tools only handle by trusting a third party. The second is building the criteria compiler as a neutral, jointly signed spec that both sides use, and selling it first as something that cuts disputes and reconciliation time, with ZK as an optional privacy mode. Partnering with or selling to Cascade or dv01 as a verification layer looks more realistic than replacing them.

• Cascade Debt

  Warehouse-line and borrowing-base software for fintech lenders and their capital partners. Its engine applies eligibility criteria and concentration limits, and its structuring product keeps a contract library of standard eligibility and borrowing-base definitions. That is close to the criteria-compiler idea, but nothing I found uses cryptographic proofs. The lender or the platform still sees the tape.

• dv01 Credit Facility Reporting

  Automates borrowing reports, concentration limits and triggers. It checks loan-level data and says it verifies that pledged loans correspond to real consumers. It is a trusted third party that sees the full tape, so it is the incumbent answer to the same trust problem, without zero-knowledge.

• Arcesium loan tape tooling

  Ingests and validates loan tapes for asset-based finance and automates validations. It is aimed at lenders and funds and has no privacy-preserving proof layer.

• ABLSoft

  Borrowing-base certificate automation with borrower-calculated and lender-calculated workflows and a variance tool for reconciling discrepancies. It shows that the reconciliation pain is real, but it relies on sharing the data, not proving the calculation.

• Situs ProMerit

  SaaS platform for managing, funding and tracking warehouse lines, integrated with loan origination systems. It is mainly mortgage-focused and has no cryptographic verification.

• Street Solutions (SSI)

  Recalculates the borrowing base on each transaction and reconciles against custodian loan schedules, for residential whole-loan warehouse lines. It is a conventional, data-sharing incumbent.

• Credora

  The closest conceptual precedent. Borrowers share real-time portfolio risk metrics with lenders without revealing positions, using secure enclaves plus ZK proofs of computation integrity. The sources I found are from 2022 and 2023 and focus on crypto trading firms and DeFi lending pools, not fintech loan tapes or warehouse facilities. I did not confirm its current status.

• Accountable

  Borrower-to-lender reporting where lenders check signed Merkle roots and ZK proofs of solvency and concentration. It targets crypto trading-firm borrowers and admits it still needs trusted third parties. I could not confirm whether it has shipped a product.

• DIA ZK

  Threshold proofs over authenticated data where the threshold is public and the value stays private. The lending use case is collateral safety in DeFi. It is a generic building block, not a borrowing-base product.

• Orochi Network zkDatabase

  A verifiable data layer for real-world assets that pitches privacy for NAV and portfolio data. It is adjacent infrastructure aimed at tokenized RWA, not off-chain warehouse facilities.
