ODATANO Brings Cardano Into SAP Environments Through Enterprise OData Integration

Cardano Gets an SAP Integration Gateway

Cardano developers now have a dedicated gateway for bringing blockchain functionality into SAP environments after developer Max Weber presented ODATANO, a Catalyst funded project built around OData and SAP CAP.

The project exposes Cardano read operations, transaction building and external signing flows through enterprise tools already used by SAP developers.

Weber, who has worked with SAP systems since 2015, presented ODATANO as a way to reduce the complexity of direct blockchain integration by placing Cardano functions behind familiar SAP and OData standards.

That matters in the enterprise context because SAP systems sit inside purchasing, finance, supply chain, logistics and other core business processes. In the presentation, Weber noted that SAP has around 440,000 customers worldwide and that a large share of global transactions touches an SAP system at some point.

OData as an Enterprise Layer for Cardano

OData is an open protocol used across SAP and Microsoft enterprise environments. It allows services to expose metadata, models, entities and actions in a format that enterprise tools can read, bind and use automatically.

ODATANO applies that model to Cardano. The project includes three main services, read operations, transaction building and external signing flows. According to Weber’s presentation, the solution supports multiple backend providers, failover logic, caching, CSL and builder implementations for transaction construction, as well as several signing options, including browser wallets, CLI keys and hardware security module integration.

During the demo, Weber showed a Fiori application that can connect a wallet, build an ADA transaction, display inputs, outputs, fee breakdown and transaction hash, then submit the signed transaction to the Cardano network. The same architecture can be used inside SAP BTP environments, Fiori applications and other CAP applications.

Catalyst Delivery and Enterprise Use Cases

The project was delivered through Catalyst milestones. Weber listed 29 Cardano related entities, 23 OData endpoints, three backends, more than 1,200 tests and over 10 documentation guides available through the project’s GitHub repositories.

The next plans include additional use cases, a publicly hosted audit or demo environment and further exploration of agentic workflows, including possible use of the x402 standard in ERP processes. During the discussion, participants also raised potential enterprise use cases such as payment settlement, audit processes, AI workflows and future integrations with real business systems.

Weber also named real business process integration and presentations at SAP events or conferences as future goals. With the Catalyst delivery completed, ODATANO moves from proposal to working developer infrastructure. Its next test is whether SAP developers and enterprise teams begin using Cardano functionality inside real operational workflows.
