Simba Chain

Simba Chain handles trusted data exchange for governments and large enterprises, registering parts, assets, credentials and organisations as verifiable on-chain records for supply-chain traceability, digital threads and compliance filings. Its customers are institutions that reconcile across organisational boundaries rather than retail users, with the US Air Force, Boeing, the Defense Logistics Agency and the Australian Defence Force appearing among its case studies.

Once a smart contract is deployed, the platform generates matching REST endpoints and a GraphQL query surface, so developers call contract methods without writing a backend, and each application gets its own interface documentation. Data can live on public or permissioned chains as needed, with decentralised identifiers and verifiable credentials supporting third-party checks. The product line spans build, assure and insights, covering deployment, on-chain event notifications and audit queries. Incubated at the University of Notre Dame in 2017 with defense research funding, it became known for auto-generated contract APIs and was later applied to additive-manufacturing part records and coffee supply-chain traceability.
