• CAP Node.js/TypeScript architecture as the backbone for all OData services
• Strict CDS entity modelling for blockchain objects (Transactions, UTxOs, Addresses, Assets, Metadata)
• SAP-ready OData V4 endpoints designed for S/4HANA, RAP, ABAP consumers and external interfaces — covering both read and write operations
• Full transaction lifecycle support: on-chain data retrieval, transaction building, external and HSM-based signing, and submission — all via typed OData V4 actions
• Blockchain data providers integrated through a modular adapter layer (Blockfrost, Koios)
• Plutus V3 smart contract interaction through schema-driven, typed contract call definitions
• Deterministic, schema-driven data contracts as the single source of truth across ingestion, normalization, signing and OData exposure
• Layered architecture with clean separation between data ingestion, transaction building, signing workflows and OData service layer
• Enterprise security patterns: HSM integration, external signing delegation, request coalescing and audit-safe key handling

ODATANO establishes a unified integration layer that enables SAP systems to:

On-Chain Data Access

• Retrieve on-chain data (transactions, UTxOs, addresses, assets, metadata) in a consistent, typed, and SAP-native format
• Query blockchain state through standard OData V4 semantics — no custom REST clients or proprietary SDKs required
• Use blockchain information directly in ERP processes: logistics, finance, supply chain, ESG reporting and automation

Transaction Building & Signing

• Build and sign Cardano transactions deterministically from within SAP processes via OData V4 actions
• Support external and HSM-based signing workflows for enterprise-grade key management
• Execute on-chain operations (ADA transfers, token transactions, smart contract interactions) triggered by SAP business events
• Leverage Plutus V3 smart contract interactions through a typed, schema-driven contract layer

Traceability & Record Anchoring (TRACE)

• Anchor business records, process steps and document hashes immutably on-chain
• Enable tamper-proof audit trails for compliance, ESG and supply chain traceability use cases
• Integrate on-chain proof-of-existence directly into SAP document and workflow processes

Monitoring & Verification (ODATANO-WATCH)

• Monitor submitted transactions deterministically and feed confirmation status back into SAP
• Verify blockchain-backed business transactions against expected on-chain state
• Close the loop between SAP process execution and on-chain finality

Privacy-Preserving Operations (NIGHTGATE)

• Execute confidential transactions on the Midnight privacy chain from SAP environments
• Access privacy-sensitive business data through a dedicated OData V4 layer with zero-knowledge guarantees
• Extend enterprise integration patterns into the privacy domain without custom tooling

Enterprise Governance & Compliance

• Build custom SAP applications on top of Cardano data using standard OData semantics
• Align all blockchain interactions with enterprise governance, auditability and compliance requirements
• Provide schema-driven data contracts as the single source of truth across all integration layers

The individual components of the organization each address a distinct integration challenge. Together they form a coherent stack:

• ODATANO handles the core data and transaction layer — read, build, sign, submit
• ODATANO-WATCH closes the feedback loop — monitoring, verification and confirmation back into SAP
• TRACE anchors enterprise records on-chain — tamper-proof, auditable, compliance-ready
• NIGHTGATE extends the stack into the privacy domain — confidential operations on the Midnight chain
• odatano.dev provides the public documentation and project surface

As the platform matures, the focus expands toward:

• End-to-end orchestration of multi-step blockchain operations within SAP workflows
• Tokenized asset management and on-chain settlement triggered by ERP events
• Automated, rule-driven payment flows based on SAP business logic
• ESG data anchoring and traceability across supply chain processes
• Confidential business process integration via Midnight, enabling privacy-preserving on-chain operations for sensitive enterprise data
• Broader Cardano ecosystem integrations exposed as SAP-consumable services

The main repository. Connects SAP systems to the Cardano blockchain via a CAP-based OData V4 API, enabling secure on-chain data access and blockchain transaction execution. Built with SAP CAP and Cardano SDKs, it provides a unified integration layer that brings Cardano into SAP processes with full enterprise-grade security and auditability.

Connects SAP systems to the Midnight privacy chain via a CAP-based OData V4 API, enabling confidential on-chain data access and privacy-preserving transaction execution. NIGHTGATE extends ODATANO's architecture into the privacy domain, acting as the gateway between SAP enterprise processes and Midnight's zero-knowledge infrastructure.

Provides deterministic monitoring and verification of blockchain-backed business transactions for enterprise systems. ODATANO-WATCH enables SAP environments to track, audit and validate the lifecycle of on-chain operations initiated through ODATANO — closing the loop between transaction submission and enterprise-grade confirmation.

Example Application: A dedicated module for anchoring business records on-chain in a tamper-proof, auditable manner. TRACE provides the foundation for traceability, compliance and ESG reporting use cases, where enterprises need verifiable, immutable proof of process steps stored on the Cardano blockchain.

The official landing page and documentation site for the ODATANO project, built with Astro. Serves as the public-facing entry point to the ecosystem, providing project context, architecture overviews, milestone updates and integration documentation at odatano.dev.

ODATANO is built with a strong focus on reliability, transparency and enterprise applicability. Demonstrating how Cardano & Midnight can be cleanly integrated into real SAP landscapes.
