We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness.
Institutional Cross-Chain Screening Gateway
Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists for FinTech and enterprise applications.
- Token Standards:
ERC-20,ERC-721,ERC-1155,SPLfor fungible and non-fungible assets. - DeFi Protocols: Custom DEXs, lending/borrowing pools, staking mechanisms, and yield strategies.
- Enterprise Logic: Multi-signature wallets, DAO governance, vesting schedules, and access control systems.
- Security: Built with
OpenZeppelinlibraries and hardened against common vulnerabilities.
Deliver a fully audited, mainnet-ready contract suite in as little as 4 weeks, backed by a 99.9% uptime SLA for deployed protocols.
Core Capabilities of the Screening Gateway
Our gateway provides the technical infrastructure for automated, real-time compliance across 50+ blockchains, enabling secure and compliant cross-chain operations.
Real-Time Risk Assessment
Automated screening of wallet addresses and transactions against global sanctions lists (OFAC, UN) and proprietary threat intelligence in under 100ms. Enforces compliance policies before cross-chain execution.
Modular Policy Engine
Deploy custom, jurisdiction-specific compliance rules (e.g., geofencing, transaction limits, entity types) via a no-code dashboard or API. Policies are enforced at the protocol level.
Audit-Ready Reporting
Generate immutable, timestamped logs of all screening decisions and policy actions. Exports to standard formats (CSV, JSON) for internal audits and regulatory reporting requirements.
Enterprise-Grade Security
Built with SOC 2 Type II principles. All data is encrypted in transit and at rest. The screening logic and policy engine are isolated in secure, audited environments.
Seamless Integration
Deploy as a middleware layer via REST API or WebSocket. Compatible with existing RPC providers, custodians, and bridge protocols. Full integration support provided.
Continuous Threat Updates
Our threat intelligence feed is updated hourly with new sanctioned addresses, malicious contracts, and high-risk patterns identified by our on-chain monitoring systems.
Business Outcomes for Your Institution
Our Institutional Cross-Chain Screening Gateway delivers measurable security and operational advantages, built on audited infrastructure trusted by leading protocols.
Eliminate Cross-Chain Compliance Risk
Automated, real-time screening across 50+ EVM and non-EVM chains prevents exposure to sanctioned addresses and high-risk entities before settlement.
Accelerate Time-to-Market
Integrate a production-ready, compliant gateway in under 2 weeks with our documented APIs and dedicated technical support, bypassing months of internal development.
Reduce Operational Overhead
Replace manual compliance reviews and fragmented chain-specific tools with a single, unified dashboard and automated alerting system.
Future-Proof Your Compliance
Our rule engine dynamically updates for new OFAC sanctions, regulatory changes, and emerging threat patterns, ensuring continuous compliance without code changes.
Enterprise-Grade Security & Audit Trail
All screening decisions are cryptographically logged on-chain, providing an immutable audit trail for regulators. Built with SOC 2 Type II compliant infrastructure.
Optimized Transaction Costs
Intelligent batching and gas optimization for screening calls reduce on-chain verification costs by up to 40% compared to native solutions.

Build vs. Buy: The Compliance Infrastructure Decision
A detailed comparison of the total cost, risk, and time investment required to build a cross-chain compliance gateway in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Chainscore Gateway |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $500K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited, custom code) | Low (pre-audited, battle-tested modules) |
Supported Chains (Initial) | 1-2 chains | Ethereum, Polygon, Arbitrum, Optimism, Base |
Ongoing Monitoring & Updates | Your DevOps team (2+ FTEs) | Managed service with 24/7 SOC2-aligned monitoring |
Regulatory Rule Updates | Manual integration (weeks of delay) | Automated, real-time updates via API |
Total Cost of Ownership (Year 1) | $400K - $800K+ | $80K - $200K |
