Core Features of Our Sanctions Oracle Aggregator
Our aggregator delivers a unified, real-time sanctions screening layer, eliminating the complexity and risk of managing multiple data sources. Built for developers who need robust compliance without sacrificing performance.
Multi-Source Data Aggregation
Integrate with 10+ leading sanctions lists (OFAC, UN, EU, HMT) and risk intelligence providers through a single API. We handle normalization, deduplication, and conflict resolution, ensuring you get a single source of truth.
Real-Time On-Chain Screening
Programmatically screen wallet addresses, transaction counterparties, and smart contracts in real-time. Our low-latency API (<50ms p99) integrates directly into your dApp's transaction flow for pre-execution checks.
Automated List Updates & Monitoring
We monitor global regulatory updates 24/7 and automatically propagate changes to your deployed contracts and APIs within minutes. Never worry about missing a critical sanctions list update again.
Configurable Risk Scoring & Logic
Go beyond binary matches. Apply custom risk-scoring models, whitelists, and business logic to reduce false positives and tailor compliance to your specific risk appetite and jurisdiction.
Auditable Compliance Logging
Every screening request and result is immutably logged with timestamps, data sources used, and applied rules. Generate comprehensive audit trails for regulators and internal compliance reviews on demand.
Gas-Optimized Smart Contract Integration
Pre-audited, upgradeable Solidity contracts designed for minimal gas overhead. Our modular architecture allows you to pay for screening only when you need it, keeping base costs low.
Business Outcomes: Reduce Risk and Scale with Confidence
Our Automated Sanctions Oracle Aggregator is engineered to deliver measurable business results. Go beyond basic screening and build with institutional-grade security and operational efficiency.
Eliminate False Positives & Reduce Operational Overhead
Our multi-source aggregation and intelligent reconciliation logic drastically reduce false positive alerts. This means your compliance team spends less time on manual reviews and more time on high-value risk analysis, cutting operational costs by up to 70%.
Guaranteed Uptime for Uninterrupted Operations
Maintain business continuity with our 99.9% SLA-backed infrastructure. Our distributed oracle network and automated failover ensure your dApp or exchange never faces downtime due to sanctions data unavailability, protecting revenue and user trust.
Future-Proof Against Evolving Regulatory Frameworks
We continuously monitor and integrate updates from global sanctions lists (OFAC, EU, UN) and emerging regulatory bodies. Our architecture allows for seamless addition of new data sources, ensuring your compliance posture is always current without engineering rework.
Scale to Millions of Users Without Performance Degradation
Built on horizontally scalable infrastructure, our oracle service handles peak loads effortlessly. Whether processing 100 or 100,000 transactions per second, response times remain consistent, enabling you to grow your user base with confidence.
Mitigate Legal & Reputational Risk with Audit Trails
Every sanctions check generates an immutable, on-chain proof of compliance. This provides a verifiable audit trail for regulators and auditors, demonstrating due diligence and significantly reducing your exposure to fines and reputational damage.
Accelerate Integration & Time-to-Market
Get production-ready in days, not months. Our comprehensive documentation, SDKs for multiple languages, and dedicated developer support streamline integration, allowing your team to focus on core product features instead of compliance complexity.
Build vs. Buy: Custom Oracle vs. Manual Processes
A cost and capability comparison for implementing sanctions screening in your Web3 application.

Sanctions List Updates | Manual, delayed (days) | Automated, real-time (<5 min) |
Security & Audit Burden | High (your responsibility) | Pre-audited, battle-tested solution |
False Positive Rate | High (15-25% typical) | Low (<5% optimized) |
Compliance Audit Trail | Manual reporting | Automated, immutable logs |
Scalability with User Growth | Requires re-architecture | Handles 10,000+ TPS natively |
Team Focus | Diverted to compliance ops | Freed for core product innovation |
Our Development and Integration Process
A structured, four-phase engagement model designed for technical leaders who need reliable, auditable, and production-ready sanctions compliance infrastructure.
Phase 1: Architecture & Risk Assessment
We conduct a deep technical review of your stack and compliance requirements. Deliverables include a detailed integration blueprint, threat model for oracle failure modes, and a clear data sourcing strategy for your target jurisdictions.
Phase 2: Core Oracle Development
Our team builds the custom aggregator logic, implementing multi-source data verification, on-chain attestation mechanisms, and failover protocols. All code follows OpenZeppelin security patterns and is written in Solidity 0.8+ or Rust (Solana).
Phase 3: Security Audit & Testing
Every oracle undergoes rigorous testing, including unit tests, integration tests with simulated data feeds, and a formal security review. We provide a comprehensive audit report prior to mainnet deployment.
Phase 4: Deployment & Monitoring
We manage the mainnet deployment and establish 24/7 monitoring dashboards for oracle health, data freshness, and SLA compliance. Includes full documentation and handover to your DevOps team.
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts that are secure by design. Our process starts with a deep technical audit of your requirements, followed by development using Solidity 0.8+ and OpenZeppelin libraries. Every contract undergoes rigorous unit and integration testing before deployment to mainnet or testnet.
Deliver a battle-tested, gas-optimized contract suite in as little as 2-4 weeks, from spec to final audit.

Frequently Asked Questions
Get clear answers on how our sanctions oracle aggregator service works, from integration to compliance.
Our service aggregates and normalizes data from multiple leading sanctions and watchlist providers (e.g., OFAC, EU, UN, local lists) into a single, high-availability API. We implement a configurable consensus model, where you can define rules (e.g., 2-of-3 providers must flag an address) to trigger alerts or block transactions, ensuring robust and customizable compliance logic.
