Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).
First truly fiat-native, regulator-grade audit trail on Cardano + Midnight
No existing product (inside or outside Cardano) records ordinary fiat sales orders – credit-card, PayPal, Klarna, etc. – as cryptographically verifiable, immutable events. Verified Ledger turns every Web2 sale into a regulator-exportable, tamper-proof receipt without forcing merchants to accept crypto payments. This removes the single biggest adoption barrier for real businesses while still leveraging Cardano’s settlement layer and Midnight’s privacy layer.
Midnight shielded parent-child NFTs + selective disclosure = privacy-first compliance
We are the first project worldwide to use Midnight’s shielded, parent-child NFTs and Compact contracts to store full PII-rich sales records (customer name, address, exact totals, tax lines) completely off any public ledger.
Dual-ledger hybrid architecture (Midnight privacy + Cardano public anchor)
First Adobe Commerce & Magento 2 extensions for on-chain transactional sales data verification
Zero integrations exist today that turn standard Adobe Commerce & Magento 2 Open Source transactional sales data into verifiable blockchain events. Our solutions will be the first publicly available, production-grade implementation of it's kind.
Platform-agnostic API layer
A single REST/OData API enables an endless amount of platforms, such as SAP, NetSuite, Shopify, BigCommerce, Agentforce Commerce, etc., to push sales events into the same shielded + public proof pipeline, creating the first universal "audit-shield-as-a-service" for enterprise retail.
Built on proven innovative solutions from the same team
Veralidity has already successfully delivered "Verified Coupons" (Fund 12) – a Cardano-native, and the world's first verifiable coupon system with production-ready Adobe Commerce & Magento 2 Open Source integrations – proving we can ship merchant-facing, seamless products that deliver real world solutions at scale.
Our solution is not another traceability pilot or crypto-only payment gateway. It's the first solution ever that provides traditional retailers using eCommerce &/or ERP platforms an immutable, regulatory compliant, privacy-preserving audit shield for every fiat and blockchain based transactional sales data event – in a way no other launched product has done before.
Describe what your prototype or MVP will demonstrate, and where it can be accessed.
Current Status – Working Proof-of-Concept (already delivered & live)
We have a fully functional, publicly accessible proof-of-concept built and shipped with Catalyst Fund 12 funding: Verified Coupons – a production extension for Adobe Commerce & Magento 2 Open Source that tokenizes promotional coupons on Cardano, and verified by Charli3 Oracles.
Live website with two examples including links to check oracle validation, last checked, etc. (Close out video includes a demo too):

Local Oracle Demo (optional supporting asset to showcase oracle innovation):
https://drive.google.com/file/d/11hS-d6XW4gwG8KauYccd_MOBKkbPhSDf/view?usp=sharing
This PoC proves our team can reliably capture real transactional sales events from Adobe Commerce & Magento 2 Open Source, batch them, and mint verifiable NFTs on Cardano mainnet – the exact same technical foundation used in this proposal.
Final MVP – What will be delivered with Fund 15 funding
Within 8 months of funding (target: aligned with Midnight mainnet):
Production Adobe Commerce / Magento 2 Open Source extensions
Merchant dashboard & one-click audit exports
Universal REST/OData API
Live demo stores & public verification (to be made available at final milestone completion)
Community Engagement & Early Access
After final milestone is approved and signed off we will open a public beta program: The first 10 merchants who onboard will receive integration for free and a monthly SaaS discount for life of the product service (% to be determined at a later date) via community waitlist.
The Fund 12 PoC already proves we ship merchant-facing tools that work with seamlessly with traditional eCommerce platforms.
Fund 15 funding upgrades this foundation to deliver the world’s first privacy-preserving, regulator-trusted sales audit shield – live on Midnight + Cardano mainnet within 8 months.
Describe realistic measures of success, ideally with on-chain metrics.
Realistic Measures of Success – Post launch 12 month projection - (all figures are optimistic projections with transparent sources & calculation logic)
Live merchants using the system
Shielded transactional sales data events minted
Shielded data volume on Midnight
Public proof NFTs on Cardano
Merchant-generated audit exports
Community Engagement
Important disclaimer
These are optimistic but fully achievable projections derived from:
Actual outcomes may vary (lower or significantly higher) depending on Midnight mainnet timing, market conditions, and regulatory tailwinds.
Every primary metric (merchants, records, NFTs, data volume) will remain 100% publicly verifiable on-chain via published Midnight contract addresses and Cardano policy IDs from day one of final milestone completion..
Please describe your proposed solution and how it addresses the problem
Audits and accounting overhead is a multi-million dollar pain point for hundreds of thousands of businesses worldwide. Veralidity's innovative solution solves the $10B+ global problem of tax audits, chargebacks, and compliance penalties for merchants using eCommerce &/or ERP type platforms by turning every fiat and crypto transactional sales event data into a traceable and verifiable sequence of events on-chain, which are an immutable, regulator-trusted, and privacy-preserving proof of truth — without forcing merchants to accept and use cryptocurrency.
Crypto & Fiat-Native Capture
Zero trust. Zero merchant crypto. Maximum audit strength. Adobe Commerce & Magento 2 Open Source extensions + universal REST/OData API capture every sales order, invoice, refund, credit memo, and tax line items— regardless of payment method (Visa, PayPal, Klarna, bank transfer, Net-terms, cryptocurrencies, etc.).
Midnight Shielded Ledger (Privacy Layer)
Cardano Public Proof (Transparency Layer)
Daily/weekly batches create a single public proof NFT on Cardano mainnet containing only necessary public data, the Merkle root + timestamp of all shielded records. This gives regulators an immutable, publicly verifiable anchor while keeping personal data hidden.
Selective Disclosure for Auditors & Tax Authorities
Retailers generate ZK selective-disclosure proofs in one click (e.g.: "prove total VAT collected = €48,291 in Germany Q4 2025" or "prove net revenue after refunds = $1.27 M") — without ever revealing individual customers or orders.
Verified transactional sales data exports are accountant and regulator-ready PDFs/CSVs with embedded Midnight proofs + Cardano NFT proofs.
GDPR/ESPR Ready
No personal data on public chain. Full 2026 DPP compliance.
Universal API for Enterprise
Retailers using SAP, NetSuite, Shopify, BigCommerce, Agentforce Commerce, and many other platforms can integrate via a single API. — one audit shield for the entire digital commerce stack.
This foundation will allow for further real world adoption in the realm of on-chain financial reporting, and data compliance as a value add for large enterprise adoption.
Protocol Data Flow
Key Paths:
This protocol is not a concept. It's the only production ready system that gives traditional retailers court-admissible, privacy-preserving, immutable proof for every fiat sale. We're not asking for funding to explore. We're asking for funding to launch the future of regulatory compliance today.
Please define the positive impact your project will have on the wider Cardano community
Our project will produce a product that will drive measurable adoption of Cardano and Midnight by solving a painful real-world problem for traditional businesses.
Seamless Retail-to-Cardano onboarding
Regulatory compliance credibility
Our project delivers ZK-verified audit evidence accepted by courts, IRS, EU tax authorities, and positions Cardano & Midnight as the gold standard for compliant enterprise blockchain, accelerating institutional adoption.
Developer ecosystem expansion
Our project which offers open-source extensions + Midnight contracts (Apache 2.0) will become the reference implementation for shielded transactional sales data by creating a reusable design pattern (parent-child sales NFTs + Cardano public anchor) that every Cardano developer can fork for supply chain, healthcare records, insurance claims, etc.
Network effects & TVL flywheel
Each merchant can potentially bring thousands of daily transactions onto Cardano & Midnight. Our solution turns compliance cost into a competitive advantage where merchants can save $10k–$100k+ yearly on audits/chargebacks, and fraud.
Adobe Commerce & Magento 2 Open Source at a Glance
This project is the on-ramp that brings traditional retail onto Cardano at scale, proves Midnight's privacy tech in production, and creates the reusable open-source foundation for the next wave of enterprise use cases — all while giving the Cardano brand unprecedented real-world legitimacy with governments, regulators and Fortune 1000 companies.
What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?
As an Adobe Solutions Partner, Veralidity has a proven track record in developing seamless Cardano integrations natively with Adobe Commerce &Magento 2 Open Source. Veralidity has also delivered in the Fund12 project "CHARLI3 Oracles - Verified discount/coupon codes for Adobe Commerce & Magento 2 Open Source eCommerce platforms", receiving 67.9 million ADA in votes, with the initiative now live on the Cardano mainnet. This solution allows merchants to create verifiable coupons on Cardano to combat fraud, while also guaranteeing that the coupon code a customer searches for and uses will work every time while shopping at their favorite retailer.
Our approach has already been validated as undeniably feasible. We've already completed a proof-of-concept with the completion of the worlds-first verifiable promotional coupons platform with coupon data verified by Charli3 Oracles. This proof-of-concept can be adapted for sales data instead of promotional coupons.
