Next Steps

1. Review Deliverables: Review all specifications for accuracy and completeness
2. Prioritize Tickets: Assign priorities and dependencies to engineering tickets
3. Start Implementation: Begin with P0 tickets (Frontend: FE-001, Backend: BE-001, Smart Contracts: SC-001)
4. Iterate: Use specifications as living documents, update as implementation progresses

---

Key Decisions Made

1. Hybrid Adapter System: Supports both DeFi and Fiat/DTL with unified interface
2. Optional Simulation: Toggleable feature for advanced users, not mandatory
3. Compliance Integration: Required compliance (LEI/DID/KYC/AML) with real-time validation
4. 2PC Pattern: Two-phase commit for atomicity across DLT and banking rails
5. Notary Registry: Immutable audit trail via on-chain notary registry
