Real-World Results: Our Integration Success Stories
Challenge: Opaque Supply Chain & Inefficient Reconciliation
The client's reliance on manual, paper-based processes and siloed data within their SAP ERP system made it impossible to track components from origin to final assembly in real-time. This resulted in costly disputes with suppliers and an inability to quickly identify the source of defects.
Key Challenges:
- Inability to verify the authenticity of raw materials.
- Lengthy invoice and payment reconciliation cycles.
- Lack of real-time visibility for customs and regulatory bodies.
- High administrative costs due to manual data entry and dispute resolution.
Our Solution: SAP & Hyperledger Fabric Integration
We designed and built a middleware solution to connect their existing SAP S/4HANA system with a permissioned Hyperledger Fabric blockchain. Key events in the supply chain (e.g., shipment creation, quality inspection, customs clearance) were automatically recorded as immutable transactions on the ledger.
- Developed custom APIs to push and pull data between SAP and the blockchain.
- Created smart contracts to automate purchase order matching and invoice settlement.
- Built a web-based dashboard for all stakeholders to view the shared, real-time ledger.
- Integrated IoT sensors to automatically record shipment conditions (temperature, humidity).
Reduction in Dispute Resolution Time
Improvement in Inventory Accuracy
Traceability of High-Value Components
Challenge: High Costs and Delays in International Payments
The client's business model was constrained by the correspondent banking system, which involved multiple intermediaries, high fees (2-5% per transaction), and settlement times of 3-5 business days. This made it difficult to compete with larger players and serve their SME client base effectively.
Key Challenges:
- Unpredictable and high foreign exchange (FX) and transaction fees.
- Lack of transparency in the payment process.
- Long settlement periods tying up client capital.
- Complex compliance and reporting requirements.
Our Solution: Core Banking & Stablecoin Integration
We integrated their core banking platform with a leading stablecoin (USDC) on a low-cost blockchain network. This created a new payment rail that bypassed the traditional SWIFT system for near-instant, low-cost international transfers.
- Integrated a crypto payment gateway for seamless fiat-to-stablecoin conversion.
- Developed smart contracts for automated, multi-signature treasury management.
- Built a compliance module that integrated with Chainalysis for real-time AML checks.
- Ensured the user interface remained simple, abstracting away the blockchain complexity.
Reduction in Average Transaction Costs
Transactions Settled in Under 5 Minutes
Increase in Transaction Volume in 6 Months
Challenge: Secure and Consented Patient Data Sharing
Data sharing between institutions was slow, required complex legal agreements for each instance, and posed significant security risks. The inability to efficiently access anonymized, aggregate data was a major bottleneck for medical research and development.
Key Challenges:
- Ensuring HIPAA compliance across multiple institutions.
- Managing and tracking patient consent for data usage.
- Preventing unauthorized access to sensitive Electronic Health Records (EHR).
- Creating an auditable log of all data access requests and approvals.
Our Solution: EHR & Decentralized Identity Integration
We developed a platform that integrated with the institutions' existing EHR systems. It used a private Ethereum blockchain and Decentralized Identity (DID) to manage patient consent and data access permissions.
- Created a consent management module where patients could grant or revoke access via a secure portal.
- Used smart contracts to enforce data access rules automatically.
- Integrated with EHR systems via HL7/FHIR APIs to fetch anonymized data upon approved request.
- Recorded every data access event on the blockchain, creating a permanent, tamper-proof audit trail.
