Technical Specification
Architecture & Proof
Settler is built on a foundation of cryptographic determinism. Every component is designed to be auditable, reproducible, and resilient to state manipulation.
Ingestion Adapter Layer
Standardized connectors for Stripe, Adyen, PostgreSQL, and custom sources.
Deterministic Match Engine
Isolated VM executing reconciliation policies with bit-perfect reproducibility.
Merkle-Tree Proof Graph
The cryptographic core ensuring every match is linked to a signed evidence root.
Multi-Region Control Plane
Global orchestration and synchronization for high-availability enterprise workloads.
Global Service Map
Orchestration across regional boundaries and data isolation protocols.

Platform overview: surfaces, control plane, and runtime boundary
Product surfaces
Operator console
Authenticated routes under src/app/app for runs, policies, proofs, and audit.
APIs + docs
Route handlers under src/app/api and OpenAPI surface.
Control plane + deterministic engine
Reconciliation + proof services
Domain + lib modules for run execution, evidence, replay, and validation.
Policy + governance
Policies, rule evaluation, approvals, and entitlement boundaries.
Observability + diagnostics
