Single fraud intelligence layer for UI and API
The same multi-agent backend powers the self-serve checker, enterprise API, and embeddable SDKs so your teams can experiment in minutes and deploy at scale without rebuilding policy logic twice. It includes risk-scoring and explainability built-in.
Unified data graph
Bring wallet behavior, contract bytecode, sanction lists, and social graphs into one investigation surface.
Score bands that matter
Low, watch, high, and block ranges tuned to capital controls, compliance, and consumer UX.
Explainable signals
Every score ships with reasoning, confidence, and remediation steps for analysts.
Auto-escalation
Push high-risk events to SOC, case management, Slack, or your own playbooks instantly.
Process
How the Monchain Check engine operates
Each step is deterministic, logged, and auditable so regulators and partners can reproduce the call. Every channel, from the free checker UI to mission-critical APIs, runs on this deterministic pipeline.
Unified data ingestion
Stream wallet intents, exchange transfers, custody instructions, and mempool data via REST, gRPC, or webhooks into one normalized schema.
Multi-agent risk scoring
Behavioral, graph, semantic, and sanctions agents collaborate in parallel, each submitting a verdict + confidence score. We normalize the vote into a 0-100 score, attach supporting evidence, and provide recommended responses.
Deterministic actions
Policies you define map scores to allow, warn, hold, or block responses which propagate back to UI kits, SDKs, or downstream systems.
Closed-loop learning
Analyst overrides, confirmed fraud, and regulator feedback retrain the models so every org benefits without sharing PII.
Converged toolkit for teams and developers
Switch between the hosted checker, SDK widgets, and raw API access without touching a different data source.
Policy enforcement
Define guardrails per desk, geography, or asset once. The same logic powers the UI checker, SDK banners, and API responses.
Agentic defense mesh
Specialized AI agents monitor behavioral baselines, sanction feeds, and consortium intel to surface only high-signal alerts.
Audit-ready explanations
Every verdict ships with traceable rationale so legal, regulators, and counterparties can replay the decision path instantly.
Integration patterns
- REST, streaming, and webhook endpoints with SDKs for TypeScript, Kotlin, and Go.
- Policy-as-code templates deployable via Terraform or GitOps pipelines.
- Real-time alerting to Slack, PagerDuty, ServiceNow, and SIEM connectors.
Deployment options
- Multi-tenant SaaS with dedicated data partitions and regional residency controls.
- Private cloud or on-prem appliance for regulated markets needing air-gapped control.

Compliance and governance ready
Travel Rule, AMLD6, MAS PSN02, NYDFS 504 reporting, and custom attestations supported out of the box.
Regulatory alignment
Exportable logs map scores to the controls regulators expect.
Data controls
Tenant-level encryption, field-level masking, and flexible retention.
Human-in-the-loop
Analyst overrides automatically document root cause analysis for audit.
