The bridge between enterprise applications and blockchain

Immutable records. Trustless verification. Full auditability across organizational boundaries. The Cardano Blockchain provides them by design. ODATANO makes them accessible to enterprise applications via OData V4. No deep protocol expertise required. No infrastructure or development overhead. Deployable as a standalone CAP Service or as a plugin data layer for full-stack applications.

Mainnet Preview Preprod

A unified OData surface for the Cardano blockchain

ODATANO maps Cardano onto OData V4 — structured entities, standard query conventions, full metadata. Chain interactions become predictable API operations that can integrate directly with existing enterprise tooling.

Read Operations

18 OData entities, 15 actions — query Blocks, Transactions, Addresses, UTxOs, Pools, Accounts, DReps and more via standard $filter, $select, $expand, $orderby operations.

Transaction Building

End-to-end Build → Sign → Submit flow. Simple ADA or native Token transfers, minting, CIP-20 metadata, Plutus V3 smart contracts interactions. All covered with ready-to-use Preview testnet examples.

External Signing

Supports signing with CIP-30 browser wallets, Cardano CLI or HSM integration. Flexible signing from local development to enterprise-grade security.

Built on proven technology

Enterprise-grade components end to end — from CAP framework to Cardano node.
