USEWhat it is used for
Representative use cases for the Clearing Operations service domain within a BIAN-aligned core-banking landscape.
- Accept, validate, and route Clearing Cycle instructions to the correct rail
- Execute transfers with debit/credit atomicity and compensation on failure
- Provide payment status tracking to channels and corporate clients (gpi-style)
- Screen instructions against sanctions lists before release

RUNRun it yourself
Each service domain is its own standalone Spring Boot repository — clone and run in seconds, or deploy onto Kubernetes with the bundled Helm chart behind the Cilium mesh.
# run this service domain standalone
git clone https://github.com/Sreenivas-Sadhu-Prabhakara/sd-clearing-operations
mvn -f sd-clearing-operations spring-boot:run
curl localhost:8080/v1/service-domain
# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-clearing-operations ./helm -n bian-operations
FAQQuestions
What is the BIAN “Operate” functional pattern?
An Operate service domain keeps a piece of operational or technical capability running day to day. Clearing Operations applies it to the Clearing Cycle.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Clearing Operations is the service domain for Payments; it manages the Clearing Cycle Operating Session and exposes it through standard BIAN action terms.
What business area does Clearing Operations belong to?
Clearing Operations sits in the Operations and Execution business area — the operational core that executes payments, positions, settlements and transactions. It runs in the bian-operations namespace as one independent Spring Boot microservice.
Is Clearing Operations production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
