# GreeksHub: Federated Cross-Venue Greeks MVP
Architecture overview
- Local primitives: LocalHedgeProblem, SharedGreeks, DualVariables, PlanDelta, AuditLog, PrivacyBudget.
- Graph-of-Contracts (GoC): lightweight in-process registry to version adapters and data contracts.
- Adapters: two starter adapters (price/vol feed, broker/execution) with TLS transport concept.
- ADMM-lite coordinator: edge-friendly coordinator that aggregates locally computed signals with secure summaries.
- Deterministic replay: plan deltas and signals are replayable for backtests and audits.
- Governance ledger: signed events, lightweight DID-based identity, policy checks.
Scope and testing
- Language: Python (production-ready, strong typing, tests).
- Testing: pytest with a small test suite; test.sh orchestrates tests and packaging sanity checks.
Development workflow
- Add small, composable components first; extend registry and adapters later.
- Run tests locally; ensure packaging metadata compiles (python build) as part of test.sh.
Contribution rules
- Follow minimal, well-documented changes; preserve existing contracts.
- Write tests for any new public API surface.
Checklist for publishing (to be checked by the final phase):
- README.md with marketing and usage detail.
- AGENTS.md present.
- test.sh runs pytest and python -m build for packaging sanity.
- READY_TO_PUBLISH present (empty file to signal completion).

# idea147-greekshub-federated-cross
GreeksHub: Federated Cross-Venue Options Greeks Aggregation for Hedge Optimization
Source logic for Idea #147
Overview
- A production-ready, Python-based MVP that demonstrates canonical primitives for local hedge problems, aggregated signals, and incremental hedge actions across multiple venues.
- Core primitives mirror CatOpt-like representations: LocalHedge, SharedGreeks, PlanDelta, with Governance via AuditLog and PrivacyBudget.
- A Graph-of-Contracts (GoC) skeleton registry to version adapters and data contracts; two toy adapters to bootstrap interoperability.
- An ADMM-lite coordinator enabling edge/cloud cross-venue aggregation with deterministic replay semantics.
What's included
- Core primitives (src/idea147_greekshub_federated_cross/core.py)
- GoC registry skeleton (src/idea147_greekshub_federated_cross/registry.py)
- Adapters (price/vol feed, broker) under src/idea147_greekshub_federated_cross/adapters/
- Lightweight coordinator (src/idea147_greekshub_federated_cross/coordinator.py)
- Minimal tests (tests/test_greeks_hub.py)
- Packaging metadata (pyproject.toml) and test script (test.sh)
Usage
- Run tests: ./test.sh
- For local experimentation, import modules from idea147_greekshub_federated_cross.*
Note
- This is an MVP scaffold intended to evolve into a production-ready architecture as per the project spec.
