Software modules

What Sentinel Ledger builds

Four purpose-built MiCA compliance software modules that together cover the complete technical obligation surface for EU CASPs: AML transaction monitoring, Travel Rule messaging, wallet and sanctions screening and an ongoing managed compliance service.

Module 01

TransactIQ Monitor

Real-time AML transaction monitoring for CASPs, engineered to meet the detection obligations of the EU Anti-Money Laundering Regulation and MiCA Article 83. TransactIQ Monitor runs a configurable rule engine across all on-chain and off-chain transfers, applies cross-chain graph traversal to detect structuring patterns that span multiple blockchains and provides an alert triage dashboard with case management and STOR workflow. Dynamic threshold calibration reduces false-positive rates by an average of 61 percent compared to static rule sets, based on telemetry from 28 live CASP deployments covering 2.1 billion monthly transactions. Cross-chain graph traversal catches 94 percent of structuring patterns missed by single-chain monitors.

EUR 32,000 fixed-price build

Module 02

TravelSync Protocol

Travel Rule compliance software that automates the collection and transmission of originator and beneficiary data for every crypto transfer above EUR 1,000 under the Transfer of Funds Regulation (EU) 2023/1113, the regulation that implements the FATF Travel Rule for EU CASPs under MiCA Article 83. TravelSync Protocol integrates simultaneously with Notabene, OpenVASP and TRP, structures all messages in IVMS101 JSON format, handles counterparty VASP lookup across the GLEIF LEI registry and provides real-time transfer-status tracking with a complete audit trail exportable for regulatory review. Covers 11 supported blockchain networks for both inbound and outbound transfers.

EUR 58,000 fixed-price build (includes ScreenShield)

Module 03

ScreenShield

Wallet screening and PEP/sanctions scoring engine that integrates Chainalysis, Elliptic and TRM Labs simultaneously through a unified API layer. Risk scores from each blockchain-analytics provider are normalised and weighted according to the CASP's internal policy, delivering a single consolidated risk signal per address without the operational overhead of three separate vendor integrations. ScreenShield supports real-time address screening at the point of transaction submission, batch API screening for existing portfolio reviews and continuous background monitoring that raises alerts when a previously low-risk address subsequently appears on a UN, OFAC, EU or national sanctions list. All screening decisions are logged with provider response payloads for use as evidence in authorisation dossiers under MiCA.

Included in Travel Rule Edition at EUR 58k

Module 04

Managed Compliance Service

An ongoing MiCA compliance service for CASPs that want continuous expert coverage without building an internal compliance engineering team. Each month Sentinel Ledger delivers rule-engine tuning based on emerging typologies, a written compliance health report formatted for regulatory review, incident response support for alerts that escalate toward a potential STOR filing and regulator liaison documentation when the national competent authority requests evidence of monitoring effectiveness. The Managed Compliance Service also covers updates required by new EBA and ESMA guidance on MiCA AML obligations as the regulatory framework continues to develop through 2026 and beyond. Clients on this service have maintained zero enforcement actions across all deployments since 2020.

Client Case Studies

Three production deployments illustrate how Sentinel Ledger's MiCA compliance software performs at scale, under regulatory scrutiny, across different CASP types.

VaultEx Netherlands

Dutch centralised exchange · Engaged Q3 2023

Challenge

Manual alert review across 14 blockchains was producing thousands of false-positive flags per week, overwhelming the compliance team and delaying legitimate withdrawal processing.

Solution

Deployed TransactIQ Monitor with dynamic threshold calibration and cross-chain graph traversal across all 14 chains, replacing static rule sets with probability-weighted triage.

68% reduction in false-positive alerts within 90 days of go-live

PayEuropa

Pan-EU payment platform · Engaged Q1 2024

Challenge

No automated Travel Rule messaging flow existed. Every outbound transfer above EUR 1,000 required manual counterparty data exchange, creating operational bottlenecks and Travel Rule non-compliance exposure.

Solution

Integrated TravelSync Protocol via Notabene and OpenVASP, achieving full IVMS101-compliant counterparty data exchange with automated message routing and acknowledgement handling.

100% of outbound transfers above EUR 1,000 Travel Rule compliant from day one of go-live

DeltaOTC Amsterdam

OTC crypto desk · Engaged Q2 2022

Challenge

No unified wallet screening or PEP/sanctions scoring was in place. Exposure across 11 analytics providers was unmanaged, creating inconsistent risk assessments across the desk's transaction flow.

Solution

Deployed ScreenShield integrating Chainalysis, Elliptic and TRM Labs with normalised risk scoring per address, replacing fragmented provider outputs with a single continuous risk score.

0 enforcement actions in 24 months since deployment

AI-Augmented Compliance

Sentinel Ledger's monitoring engines embed machine-learning models trained on real alert outcomes — reducing noise, catching novel typologies and keeping rule sets aligned with evolving MiCA guidance.

ML Transaction Risk Scoring

Gradient boosting models trained on historical alert outcomes assign a continuous risk score to each transaction, replacing binary pass/fail thresholds with probability-weighted triage. This reduces analyst review load by surfacing only the top percentile of risky transfers for human investigation.

Typology-Based Anomaly Detection

Graph neural networks traverse cross-chain transaction graphs to identify structuring, layering and integration patterns missed by single-chain rule sets. The SL-RN-2025-04 research note documents a 94% detection rate for cross-chain structuring patterns across the 2.1 billion transactions screened monthly.

LLM-Assisted Regulatory Change Tracking

A language-model pipeline monitors MiCA, AMLR and EBA guideline updates, flags paragraphs relevant to the client's rule-engine configuration and generates a change-impact summary for the compliance team to review. This eliminates the manual effort of tracking legislative amendments across multiple EUR-Lex and authority publication feeds.

False-Positive Feedback Loops

Analyst disposition decisions (true positive/false positive) feed back into the risk-scoring model weekly, continuously narrowing thresholds to the client's specific transaction mix. Clients on the Managed Compliance Service see an average 61% false-positive reduction within six months of onboarding, compounding over time as the model adapts to their portfolio.

How We Build It

The Sentinel Build Framework is a five-phase delivery model that produces audit-ready MiCA compliance software — with a compliance evidence package included at every phase gate.

1

Phase 1 · 2 weeks

Compliance Mapping

Map MiCA/AMLR requirements to software specifications. Every regulatory obligation is traced to a rule-engine configuration item, creating a complete requirement traceability matrix that satisfies regulator requests for evidence of systematic monitoring design.

Deliverable: Requirement traceability matrix
2

Phase 2 · 1 week

Architecture Design

Define the rule-engine data model, blockchain-analytics integration points and API contracts. Architecture decisions are documented against the client's chain portfolio, transaction volume and screening-database requirements, producing a record that feeds directly into the compliance evidence package.

Deliverable: Architecture decision record
3

Phase 3 · 4–8 weeks

Build and Integration

Build the core monitoring engine, wire blockchain-analytics APIs and implement IVMS101 messaging flows. Integration scope is fixed by the architecture decision record, preventing scope creep. The staging environment is delivered at the end of this phase for client review and alert simulation testing.

Deliverable: Deployed staging environment
4

Phase 4 · 2 weeks

Validation and Evidence

Run scenario testing and alert simulation against the staging environment. Each test case corresponds to a MiCA AML typology. Test results, alert thresholds and rule-engine configuration are compiled into the compliance evidence package, formatted for submission to the national competent authority.

Deliverable: Compliance evidence package
5

Phase 5 · 2 weeks + 30 days

Go-Live and Hypercare

Deploy to production, deliver operator training and tune alert thresholds against live transaction data during a 30-day hypercare period. Sentinel Ledger remains on-call for any alert calibration or integration issue arising during the first month of live monitoring.

Deliverable: Production system + 30-day hypercare support

Integrations and Ecosystem

Sentinel Ledger's API layer connects to every major blockchain analytics, Travel Rule and KYC/KYB provider in the EU CASP ecosystem — all through a single integration point.

Chainalysis Blockchain Analytics
Elliptic Blockchain Analytics
TRM Labs Blockchain Analytics
Scorechain Blockchain Analytics
Notabene Travel Rule
OpenVASP Travel Rule
TRP Travel Rule Protocol
Onfido KYC/KYB
Sumsub KYC/KYB
Jumio KYC/KYB
Refinitiv World-Check Sanctions/PEP Screening

All integrations use open APIs. No proprietary connector lock-in: if you switch analytics provider, the ScreenShield configuration layer updates without a full redeployment. Clients who have moved from one analytics provider to another have done so within a single two-week sprint with no monitoring downtime.

Industries Served

MiCA compliance obligations vary by CASP category. Sentinel Ledger has delivered production monitoring systems for eight distinct CASP types operating under EU jurisdiction.

Centralised Crypto Exchanges (CEX)

High transaction volumes and multi-chain exposure create both alert fatigue and blind-spot risk. Sentinel Ledger's TransactIQ Monitor applies dynamic threshold calibration tuned to exchange transaction mixes, reducing false-positive rates without compromising detection coverage.

Crypto Custodians and Sub-custodians

Custodians face strict DORA operational resilience requirements alongside AML monitoring obligations. Sentinel Ledger's architecture separates the monitoring engine from client asset paths, supporting evidence-based DORA ICT risk assessments alongside standard MiCA AML deliverables.

Wallet Providers

Custodial wallet providers are full CASPs under MiCA; non-custodial providers face risk-based due diligence requirements when interacting with CASPs. Sentinel Ledger's ScreenShield provides address-level risk scoring applicable to both custody models without requiring access to private key infrastructure.

OTC Crypto Desks

OTC desks transact in large block sizes with a concentrated counterparty pool, making each individual transaction a higher-value compliance decision. Sentinel Ledger's per-address risk scoring normalises outputs from multiple analytics providers into a single, auditable risk record per counterparty.

FinTech Payment Processors with Crypto Rails

FinTech processors adding crypto settlement to existing fiat flows must comply with both the Transfer of Funds Regulation and MiCA AML rules simultaneously. Sentinel Ledger's TravelSync Protocol handles the crypto Travel Rule leg while leaving fiat messaging infrastructure untouched.

Token Issuers (Utility, ART, EMT)

Asset-referenced token (ART) and e-money token (EMT) issuers carry MiCA's most demanding obligations, including reserve reporting and redemption monitoring. Sentinel Ledger's rule engine supports token-level monitoring overlays that track redemption flows against reserve thresholds in real time.

Stablecoin Issuers

Stablecoin issuers operating under MiCA's Title IV EMT or ART authorisation must demonstrate continuous AML monitoring of token circulation. Sentinel Ledger integrates with on-chain token supply data to correlate mint and burn events with counterparty screening outcomes.

Crypto Brokers and Trading Platforms

Brokers intermediating between retail clients and liquidity venues require customer-level risk aggregation across multiple trading sessions and blockchains. Sentinel Ledger's customer risk profile layer aggregates per-transaction risk scores into a continuously updated client risk rating aligned with the FATF risk-based approach.

What Determines Your Price

MiCA compliance software cost is driven by scope, not by vendor margin. These six factors determine where a build lands within our pricing bands — and all are discussed during the free scoping call before any proposal is issued.

1

Number of Blockchains to Monitor

Each additional chain requires analytics API configuration and rule-set calibration. The standard Monitor Edition covers up to 5 chains; additional chains add incremental integration cost per chain added to the monitoring scope.

2

Analytics Providers to Integrate

Each blockchain-analytics provider — Chainalysis, Elliptic, TRM Labs — has its own API contract. Multi-provider builds add integration and normalisation work, as the ScreenShield layer must unify risk scores across different output schemas.

3

Travel Rule Protocol Coverage

A single-protocol TravelSync build (for example Notabene only) is the minimum Travel Rule scope. Adding OpenVASP or TRP alongside extends the integration scope and the IVMS101 message-routing configuration proportionally.

4

Audit Depth and Evidence Requirements

Clients targeting authorisation in a strict jurisdiction — DNB Netherlands, BaFin Germany, AMF France — typically require a more comprehensive compliance evidence package, which extends the Validation and Evidence phase by up to two additional weeks.

5

KYC/KYB Integrations

Adding Onfido, Sumsub or Jumio to the ScreenShield build alongside analytics providers extends API scope. Each KYC/KYB provider has a distinct identity-verification workflow that must be mapped to the ScreenShield risk profile output format.

6

Ongoing Managed Service

The EUR 12,000/month Managed Compliance Service replaces internal compliance resource cost, which typically exceeds EUR 20,000/month for a CASP with sufficient transaction volume to require dedicated monitoring staff — making the managed model the more cost-effective option for most mid-market CASPs.

Build vs Buy MiCA Compliance Software

CASPs approaching MiCA compliance face a recurring build-vs-buy decision. This table maps four approaches against the dimensions that matter most to a compliance officer and a CTO.

Approach Time to compliance Ongoing maintenance Regulatory audit readiness Total 2-year cost Best for
Dedicated rule-engine with blockchain analytics (custom build) 12–18 months High — in-house team required Good if built to spec EUR 400k–800k Large exchanges with a compliance engineering team
Open-source AML libraries (e.g. Actus, custom rules) 6–12 months Very high — constant updates needed Poor without a compliance-domain overlay EUR 200k–500k (hidden costs) Teams with deep FinTech engineering experience
Manual compliance processes Immediate but unsustainable Grows linearly with transaction volume Fails at scale — regulators require automated monitoring Low upfront, EUR 500k+ at scale Pre-licence CASPs only (temporary)
Sentinel Ledger (fixed-price build) 8–16 weeks Low — rule tuning by SL team Excellent — evidence package included EUR 32k–58k build + optional EUR 12k/month CASPs needing fast, audit-ready MiCA compliance

Travel Rule Protocol Comparison

The Travel Rule can be implemented via several interoperable protocols. The right choice depends on your counterparty VASP universe, your jurisdiction and your timeline. Sentinel Ledger's TravelSync Protocol supports all three.

Protocol IVMS101 compliant VASP directory Counterparty lookup Open standard Best for
Notabene Yes Yes (global) Automated Partially open Exchanges with a large global counterparty VASP set
OpenVASP Yes Decentralised (Ethereum ENS) Peer-to-peer Fully open source CASPs wanting a decentralised, non-commercial protocol
TRP — Travel Rule Protocol Yes SWIFT-adjacent network Network-based Industry consortium Institutional CASPs with banking relationships
Proprietary bilateral exchange Partial No directory Manual No Legacy bilateral arrangements only — not recommended for MiCA compliance

No Vendor Lock-In

All integrations use open APIs. Switch blockchain analytics providers or Travel Rule protocol partners without redeployment.

Defined Exit and Knowledge Transfer

A documented handover procedure at the end of every engagement ensures your team can operate and extend the system independently.

How to Choose a MiCA AML Software Vendor

Most MiCA compliance software failures trace back to a procurement decision made without the right questions. These five criteria separate production-ready vendors from demo-only providers.

1. Verify production deployments, not demos

Ask the vendor for a named list of EU CASP deployments with go-live dates. A demo environment and a production deployment are different things. Sentinel Ledger has 28 active deployments across EU CASPs with documented go-live dates available on request.

2. Confirm Travel Rule protocol coverage

Your counterparty VASPs may use Notabene, OpenVASP or TRP. If your vendor only supports one protocol, you will have gaps in your Travel Rule compliance. Ask for the complete VASP directory coverage before signing.

3. Understand the false-positive tuning process

A monitoring rule engine that produces too many false positives is operationally unsustainable. Ask what the vendor's false-positive rate is across deployments, how it is measured and what the tuning process looks like post-go-live. Sentinel Ledger's dynamic threshold calibration delivers a 61% average false-positive reduction versus static rule sets.

4. Check rule-engine auditability

Your national competent authority (DNB, BaFin, AMF or AFM) may review your monitoring configuration. The rule-engine logic must be documented, auditable and explainable in plain language. Ask for a sample configuration document before engaging any vendor.

5. Verify ISO 27001 and evidence package delivery

Your MiCA authorisation dossier will require evidence of your monitoring setup. Ask whether the vendor's build produces a compliance evidence package as standard output and whether they hold ISO 27001. Sentinel Ledger holds cert NL-27001-9920, issued by DNV. The evidence package is a standard deliverable in every build.

Dr. Joost van Dijk

Dr. Joost van Dijk holds a PhD in Applied Cryptography from TU Delft (2013) and spent six years as an analyst at FIU-Netherlands (Financial Intelligence Unit) before founding Sentinel Ledger B.V. in Amsterdam in 2020. His specialism is real-time AML transaction monitoring and Travel Rule messaging protocols for crypto-asset service providers.

"In 2019, while reviewing flagged transactions at FIU-Netherlands, I encountered a VASP that had screened 4 million transactions manually over six months, missing 23 cross-chain hops that a rule engine could have caught in real time. The gap between data availability and operational tooling was not a technology problem. It was an integration problem — and that gap became the founding thesis for Sentinel Ledger."

Frequently Asked Questions

Answers to the most common questions from CASPs evaluating MiCA compliance software.

What is MiCA compliance software?

MiCA compliance software is purpose-built tooling that helps crypto-asset service providers (CASPs) meet the technical obligations of the Markets in Crypto-Assets Regulation (EU) 2023/1114. It typically covers AML transaction monitoring, Travel Rule messaging, wallet and sanctions screening, suspicious transaction reporting (STOR) and audit-trail generation. Sentinel Ledger builds and deploys these systems for EU CASPs.

How much does MiCA compliance software cost?

Sentinel Ledger offers three pricing tiers: Monitor Edition (TransactIQ Monitor build) at EUR 32,000 fixed price, Travel Rule Edition (TravelSync Protocol and ScreenShield) at EUR 58,000 fixed price and Managed Compliance Service at EUR 12,000 per month for ongoing monitoring, tuning and regulator liaison. A fixed-price discovery sprint is available at EUR 8,000 and is deducted from the build price if the engagement proceeds.

How do I choose a MiCA AML software vendor?

Verify the vendor has deployed blockchain analytics integrations in production. Confirm Travel Rule support covers your counterparty VASP universe (Notabene, OpenVASP or TRP). Ask how false-positive rates are measured and what tuning process exists post-go-live. Check that the rule-engine logic is auditable and can be reviewed by your regulator. Confirm the vendor holds ISO 27001 and can supply an evidence package for your authorisation dossier.

What is the Travel Rule under MiCA?

The Travel Rule is the FATF-originated requirement implemented under MiCA Article 83 via the Transfer of Funds Regulation (EU) 2023/1113. It requires CASPs to collect and transmit originator and beneficiary data alongside any crypto transfer above EUR 1,000. The data must be structured in IVMS101 format and exchanged with the counterparty VASP before settlement.

Does Sentinel Ledger integrate with Chainalysis and Elliptic simultaneously?

Yes. Sentinel Ledger's ScreenShield engine integrates Chainalysis, Elliptic and TRM Labs simultaneously through a unified API layer. Risk scores from each provider are normalised and weighted per the client's policy, so CASPs receive a single consolidated risk signal per address.

How long does a Travel Rule software deployment take?

Sentinel Ledger's Travel Rule Edition deploys in 10 to 16 weeks from project kickoff to go-live, covering compliance mapping, architecture design, API integration, scenario testing and a supervised go-live with 30-day hypercare.

What does 0 enforcement actions mean for clients?

Across all 28 active Sentinel Ledger deployments, no client CASP has received a regulatory enforcement action relating to AML monitoring or Travel Rule compliance since deployment.

Can the monitoring rules be tuned after go-live?

Yes. Rule tuning is a standard part of the 30-day hypercare period included with every build and is a core component of the Managed Compliance Service. Threshold calibration, typology updates and analytics-provider weight adjustments can be applied without redeployment through the TransactIQ Monitor configuration layer.
