OData V4 services exposing the Cardano and Midnight blockchains.
Packaged as SAP CAP plugins - install with npm, configure via
cds.requires, blockchain services register
automatically.

Anchor business data transparently on Cardano, or prove it without revealing it on Midnight. Same CAP plugin model, same OData surface.
Public, auditable, enterprise-grade. On-chain data and transactions exposed as OData entities and actions - readable by SAP Fiori, Excel, Power BI, or any OData client.
Shielded transfers, Compact smart contracts, and zero-knowledge attestations - prove compliance without revealing business data.
ODATANO is a bridge between business applications and public blockchains. Tools enterprises already use like SAP Fiori, Excel, Power BI, or any OData-aware client can read on-chain data and trigger transactions without learning complex blockchain APIs. ODATANO talks to Cardano; NIGHTGATE talks to Midnight - both take care of the hard parts like multiple data providers, caching, and safely building and submitting transactions on your behalf.

Both plugins expose their blockchain as OData V4 entities and
actions. Standard query options ($filter,
$select, $expand, $orderby)
work as in any OData service, and full service metadata is
available at $metadata.
@odatano/core
CardanoODataService: 18 entities, 16 actions.
Blocks, Transactions, Addresses, UTxOs, Pools, Accounts, DReps,
Protocol Parameters, transaction CBOR parser. Lazy on-demand
indexing with TTL refresh.
CardanoTransactionService: 13 actions. ADA
transfers, multi-asset, mint, Plutus V3 spend, CIP-20 metadata,
CIP-31 reference inputs, CIP-33 reference scripts. Buildooor is
the sole transaction-building engine.
CardanoSignService: 8 actions. External signing via
CIP-30 wallets or Cardano CLI; server-side signing via PKCS#11
HSM. Private keys never reach the server in any flow.
@odatano/nightgate
NightgateService: a built-in crawler indexes
Midnight blocks from Substrate RPC with reorg detection and
catch-up sync. Worker-thread-isolated wallet sessions - read-only
via viewing key or full signing.
Deploy and call Compact-compiled smart contracts
(deployContract, submitContractCall),
send NIGHT with auto-detected receiver ledger, async job model
with getJobStatus polling.
ZK predicate attestations prove hidden values meet thresholds
without disclosure. Document anchoring with on-chain
verification, plus shieldFunds /
unshieldFunds cross-ledger shifts.
Applications and libraries built on the ODATANO plugins - from supply-chain NFTs to zero-knowledge battery passports.
Digital battery passports anchored on Cardano as CIP-25 NFTs. Sensitive data stays encrypted off-chain - Merkle proofs disclose single fields, and Groth16 predicates prove thresholds like carbon footprint on the Cardano ledger itself.
The shielded twin of DAYPASS, running on Midnight via @odatano/nightgate. One dataset, three stakeholder views - sensitive metrics are proven with ZK attestations without ever revealing the values.
Tracks pharmaceutical batches across manufacturer, distributor, and pharmacy with NFTs minted under a Plutus V3 policy - each handoff anchors certificates and cold-chain telemetry on-chain.
On-chain settlement of B2B raw-material orders against attested inventory and Charli3 oracle price feeds. A custom Plutus V3 minting policy enforces inventory, price ceiling, payment, and deadline atomically.
Anchors balance sheets and income statements on Cardano as CIP-10 label-1447 metadata following the Cardano Foundation Reeve spec - verifiable accounting without a smart contract.
Payment-gating library for SAP CAP - gated OData endpoints return HTTP 402 until the caller proves on-chain settlement. No database, no smart contract: the UTxO model is the replay defense.
Pure-TypeScript zero-knowledge toolkit powering DAYPASS - Groth16 proving and verification plus Poseidon hashing on BLS12-381, with no native dependencies.
Deterministic monitoring and verification of blockchain-backed business transactions for enterprise systems - confirms that what your ERP recorded is what the chain settled.
Runtime and dependencies.
Two chains, one integration model. Install a plugin, add one config block, and your CAP service speaks blockchain. Run it standalone on your own server, inside SAP BTP, or inside your existing CAP application.
