# TradeSeal: Federated Compliance & Audit Fabric for Multi-Venue HFT

TradeSeal provides a production-ready, privacy-preserving federation layer to coordinates local order data and risk signals across venues with central policy engines. This repository implements a minimal yet production-conscious MVP that captures core primitives, a lightweight federation/admm-like reconciler, a governance ledger with attestations, and pluggable adapters for FIX/WebSocket/REST feeds.

Highlights
- Canonical primitives: LocalOrder, SharedSignals, DualVariables, PlanDelta, AuditLog, and Policy block
- Federated optimization: asynchronous, ADMM-lite reconciliation with delta-sync and auditable logs
- Attested governance: cryptographic attestations and a tamper-evident ledger (with optional ZK-proof stubs)
- Adapters: registry for FIX and REST adapters; transport layer with basic role-based access
- Privacy by design: secure aggregation and optional data leakage budgets

Project structure
- tradeseal/core.py: primitives and data models
- tradeseal/federation.py: asynchronous ADMM-lite reconciler and delta-sync
- tradeseal/governance.py: governance ledger and attestations
- tradeseal/adapter_registry.py: starter adapters for FIX and REST feeds
- tests/: basic unit tests for core components and delta-sync
- tradeseal/contract_registry.py: graph-of-contracts registry with versioned contracts and attestation helpers

How to run tests
1) Install dependencies (if any): plain Python standard library is used for core parts
2) Run tests: ./test.sh

This repository is designed as a foundation for a full production-ready system. It intentionally includes hooks and extensibility points for future work.
