Financial INformation Chain Anchoring: A Reeve-compatible SAP CAP service for cryptographically verifiable anchoring of accounting and financial-report data on the Cardano blockchain. Powered by @odatano/core.
FINCA manages organisations, journal-style transactions, and financial reports (Balance Sheet, Income Statement); serialises them into the CIP-10 label-1447 metadata format (Reeve spec); builds unsigned Cardano transactions via ODATANO; has them signed by a CIP-30 browser wallet; and polls confirmation status.
