aid: simba-chain name: SIMBA Chain description: >- SIMBA Chain is a South Bend, Indiana enterprise data company spun out of the University of Notre Dame under U.S. Department of Defense research funding. Its platform — marketed today as SIMBA Trace and built on the SIMBA Blocks / Build / Ensure / Insights product suite — turns products, components, assets, credentials and organizations into tamper-evident, cryptographically sealed records on permissioned blockchains (Ethereum, Hyperledger Fabric, Polygon, Quorum) for supply-chain visibility, traceability, digital thread and EU Digital Product Passport compliance. Developers deploy Solidity or Chaincode smart contracts through SIMBA Build, which auto-generates a REST API (OpenAPI + SwaggerUI) per application, plus a GraphQL query surface, event/notification subscriptions, and DID/Verifiable Credential issuance through SIMBA Ensure. Customers include the U.S. Air Force, Boeing, the Defense Logistics Agency and the Australian Defence Force. deliveryModel: model: saas open_source: false commercial: true callable_host: false label: Hosted service · you call their endpoint confidence: medium source: - pricing generated: '2026-08-28' method: derived image: https://simbachain.com/wp-content/uploads/2024/01/SIMBA-Chain-logo.svg url: https://raw.githubusercontent.com/api-evangelist/simba-chain/refs/heads/main/apis.yml x-type: company x-source: harvest:secondary-market specificationVersion: '0.20' created: '2026-08-27' modified: '2026-08-27' tags: - Company - Blockchain - Supply Chain - Traceability - Digital Product Passport - Smart Contracts - Identity - Verifiable Credentials - Defense - Government - Data Management maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io apis: - aid: simba-chain:simba-chain-member-service-api name: SIMBA Blocks Member Service API description: >- The organization, user, role, permission and API-credential control plane behind SIMBA Build.

When a smart contract is deployed into an application, Blocks auto-generates REST endpoints for every method and public variable of that contract — POST to invoke, GET to query prior invocations — under /v2/apps/{application}/contract/{contract_name}/{method_name}/, with a per-application OpenAPI definition and SwaggerUI rendered from the application's overview page. Also carries wallet/account creation, file bundles (_bundleHash), off-chain storage, transaction validation and the subscription/notification surface. Because the contract shape is generated per deployed application, there is no single tenant-independent published OpenAPI; the generated definition is reachable only inside an authenticated application.
