Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.
Deploy with confidence, backed by battle-tested code and formal verification.
ERC-20, ERC-721, ERC-1155, ERC-4626, and custom logic.OpenZeppelin libraries and patterns; includes comprehensive unit and integration testing.Typical Outcomes:
A purpose-built, real-time sanctions screening solution designed to meet the rigorous demands of financial institutions and DeFi protocols. We deliver the accuracy, speed, and reliability required for global operations.
Automatically ingest and normalize sanctions data from over 30 global authorities (OFAC, EU, UN, HMT) with sub-5 minute latency. Eliminate manual list management and ensure your application is always screening against the latest data.
Synchronous and asynchronous API endpoints with <100ms p99 latency, built for high-throughput environments. Scale to millions of daily checks without performance degradation or dropped requests.
Proprietary algorithms go beyond simple string matching to handle name variations, transliterations, and partial data. Dramatically reduce false positives while maintaining regulatory-grade detection accuracy.
Every address and transaction check is cryptographically logged with timestamps, request data, and match reasoning. Generate immutable, court-ready compliance reports on demand for regulators and auditors.
Assign dynamic risk scores based on jurisdiction, list type, and match confidence. Integrate custom business logic to automate decisions for low-risk matches and escalate only high-risk alerts.
SOC 2 Type II certified infrastructure with end-to-end encryption, zero-trust architecture, and regular penetration testing by third-party firms like Trail of Bits. Your compliance data is as secure as your core application.
Automate sanctions screening with a real-time, on-chain data feed. Eliminate manual checks, reduce false positives, and maintain a verifiable compliance audit trail for regulators.
Our oracle ingests updates from OFAC, UN, EU, and other global sanctions lists, delivering them to your smart contracts within seconds. Ensure your DeFi protocol or exchange blocks prohibited addresses the moment they are listed.
Replace manual, error-prone compliance processes with automated, deterministic checks. Every transaction can be programmatically validated against the latest sanctions data, creating an immutable proof-of-compliance record.
Built on redundant, decentralized infrastructure with a 99.9% uptime SLA. Our service includes multi-chain support (Ethereum, Polygon, Arbitrum, etc.) and is backed by 24/7 technical support for enterprise clients.
Every oracle update and on-chain verification is cryptographically signed and timestamped. Provide regulators with a transparent, tamper-proof log of all compliance actions, significantly simplifying audits and examinations.
A detailed comparison of the costs, risks, and time investment required to build a sanctions oracle in-house versus using Chainscore's managed service.
| Key Factor | Build In-House | Chainscore Oracle |
|---|---|---|
Initial Development Time | 4-9 months | 2-4 weeks |
Upfront Engineering Cost | $150K - $300K+ | $0 |
Security & Audit Overhead | High (Your Risk) | Pre-audited & Insured |
Data Source Integration | Manual (OFAC, EU, UN, etc.) | Pre-integrated & Normalized |
Update Latency | Hours to Days | < 60 Seconds |
Ongoing Maintenance FTE | 1-2 Engineers | Fully Managed |
Total Cost (First Year) | $300K - $600K+ | Starting at $25K/year |
Time to First Transaction | 6+ months | < 48 hours |
Compliance Coverage | Basic Lists | Global (OFAC, EU, UK, UN, 40+) |
A structured, four-phase approach designed for technical leaders. We deliver a production-ready sanctions oracle with clear milestones, security guarantees, and ongoing support.
We handle the complete technical integration of our sanctions list API into your existing stack. Includes environment setup, API key provisioning, and configuration for your specific compliance rules and risk thresholds.
Before go-live, your integrated solution undergoes rigorous security validation. We perform penetration testing on the API endpoints and review your implementation for common vulnerabilities (e.g., replay attacks, data integrity).
Deploy to a staging environment identical to production. We conduct load testing to validate performance under peak traffic (10k+ TPS) and ensure sub-100ms response times for sanctions checks, guaranteeing scalability.
We manage the production cutover and provide real-time monitoring dashboards for uptime, latency, and list update status. Includes automated alerts and a 99.9% uptime SLA backed by our globally distributed node infrastructure.
Secure, production-ready smart contracts built for scale and compliance.
We architect, develop, and audit custom Solidity/Rust smart contracts that form the immutable backbone of your Web3 application. Our focus is on security-first development and gas optimization to protect assets and minimize operational costs.
ERC-20, ERC-721, ERC-1155, and bespoke contract systems.TransparentProxy, UUPS) for future-proofing.Deploy with confidence. We deliver battle-tested contracts that have secured over $500M+ in on-chain value for our clients.
Get clear answers on implementation, security, and integration for our on-chain sanctions screening solution.
Standard integration takes 1-2 weeks from contract signing to production deployment. This includes smart contract integration, testing on a staging environment, and final configuration. Complex multi-chain deployments or custom list requirements may extend this timeline, which we scope during the initial technical assessment.
