Core Technical Capabilities
Our sanctions screening API is built on a robust, purpose-built infrastructure designed for the scale and compliance demands of financial institutions and high-volume crypto platforms.
Real-Time Transaction Screening
Screen wallet addresses and transactions against OFAC, UN, and EU sanctions lists with sub-second latency. Our API integrates directly into your transaction flow to block non-compliant transfers before they are finalized.
Comprehensive Risk Intelligence
Go beyond simple list matching. Our system analyzes on-chain patterns, cross-chain activity, and entity clustering to identify high-risk wallets associated with sanctioned protocols, mixers, or stolen funds.
Audit-Ready Compliance Logging
Every screening request and result is immutably logged with a Chainscore Proof. Generate detailed, tamper-evident audit trails for regulators in minutes, not days.
Enterprise-Grade Security & Privacy
Your data is encrypted in transit and at rest. We are SOC 2 Type II compliant and operate a zero-trust architecture. Screening requests are processed without storing sensitive PII.
Automated List Updates & Monitoring
Sanctions lists are updated automatically within 5 minutes of official publication. Our 24/7 monitoring ensures you are always screening against the latest regulatory requirements.
Business Outcomes for Your Protocol
Integrating Chainscore's Sanctions Screening API delivers measurable security and operational advantages, directly impacting your protocol's compliance posture and user trust.
Automated Regulatory Compliance
Real-time screening against global sanctions lists (OFAC, UN, EU) ensures every transaction is compliant by design, eliminating manual review and reducing legal exposure.
Reduced Risk & Liability
Proactively block interactions with sanctioned addresses before they settle. Our continuously updated data sources and deterministic logic provide a verifiable audit trail for regulators.
Faster Time-to-Market
Deploy a production-ready compliance layer in days, not months. Our simple API integration requires no internal AML team, accelerating your launch and fundraising timelines.
Enhanced User Trust & Safety
Demonstrate a commitment to secure and lawful operations. Protect your community and liquidity pools from bad actors, building credibility with users, partners, and investors.
Operational Efficiency & Cost Savings
Eliminate the overhead of building, maintaining, and updating an in-house screening system. Convert fixed engineering and legal costs into a predictable, scalable operational expense.
Future-Proof Compliance
Our infrastructure automatically adapts to new regulatory requirements and list updates. Ensure your protocol remains compliant as the global landscape evolves, without code changes.

Our Delivery Methodology
We deliver production-ready sanctions screening with a structured, transparent approach that ensures security, speed, and seamless integration.
Compliance & Risk Assessment
We begin with a deep analysis of your specific regulatory requirements (FATF, OFAC, MiCA) and risk profile to tailor our screening rules and thresholds.
API Integration & Configuration
Our engineers provide dedicated support for integrating our RESTful API, configuring webhooks for real-time alerts, and setting up custom watchlists.
Data Pipeline Implementation
We deploy and manage the secure data ingestion pipeline from your on-chain sources (nodes, indexers) to our screening engine, ensuring data integrity.
Testing & Validation
We conduct rigorous testing with historical and synthetic threat data to validate screening accuracy and fine-tune false positive rates before go-live.
Production Deployment
We manage the phased rollout, load testing, and final deployment to production, ensuring zero downtime for your existing services.
Ongoing Monitoring & Updates
We provide continuous monitoring, daily list updates, and periodic compliance reviews to adapt to evolving regulatory landscapes and threats.
