Architecture

OpenTRMS is a modular Spring application. Each Maven module owns one slice of the trade lifecycle and depends only on the contracts it needs.

Module	Responsibility
trms-api	REST surface, Swagger UI, request validation
trms-domain	Deal model, lifecycle state machine
trms-event-store	Append-only, hash-chained event log
trms-settlement	Netting, settlement instructions
trms-closeout	End-of-day cut-off, curves, accruals
trms-credit	Counterparty lines and exposure
trms-auth	Scopes, entitlements, approval chains
trms-ai	Spring AI ChatClient agents and the MCP server

A deeper architecture walkthrough is in progress.
