Cross-Chain Compliance Scoring Gateway
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Every contract undergoes formal verification and multi-stage audits before deployment.
- Gas Optimization: We reduce transaction costs by 20-40% through expert optimization.
- Full Lifecycle Support: From initial design to mainnet deployment and post-launch upgrades.
Deliver a secure, auditable, and efficient foundation for your dApp in as little as 4 weeks.
Core Capabilities of Our Scoring Engine
Our gateway transforms raw on-chain data into actionable, risk-weighted compliance scores, enabling secure cross-chain operations. Built for institutions requiring verifiable, real-time risk assessment.
Multi-Chain Risk Aggregation
Unified risk scoring across 15+ EVM and non-EVM chains. We ingest and normalize data from Ethereum, Solana, Arbitrum, and Polygon to provide a single source of truth for wallet and transaction risk.
Real-Time Sanctions Screening
Continuous monitoring against OFAC, global sanctions lists, and proprietary threat feeds. Flags high-risk wallets and transactions in real-time before settlement, preventing regulatory exposure.
Behavioral Anomaly Detection
AI-driven models identify suspicious patterns like wash trading, money laundering cycles, and protocol exploitation attempts that static rules miss. Continuously trained on billions of transactions.
Programmable Compliance Rules
Define custom risk parameters and scoring logic via our API. Tailor thresholds for DeFi exposure, counterparty concentration, and jurisdictional rules to match your specific compliance policy.
Audit-Ready Reporting
Generate immutable, timestamped audit trails for every score calculation. Export detailed reports showing data sources, rule triggers, and decision logic for regulators and internal audits.
Enterprise-Grade Security & Uptime
SOC 2 Type II compliant infrastructure with private RPC endpoints, zero-data persistence policies, and end-to-end encryption. Guaranteed availability for critical compliance operations.
Business Outcomes for Your Protocol
Our Cross-Chain Compliance Scoring Gateway delivers measurable infrastructure improvements, enabling your protocol to scale securely and operate with institutional-grade trust across all major networks.
Accelerated Market Entry
Deploy a production-ready compliance layer in under 3 weeks, bypassing months of in-house development. We provide the full-stack gateway, integration SDKs, and documentation.
Institutional-Grade Security & Audit Trail
Receive a cryptographically verifiable audit trail for every cross-chain transaction. Our system architecture is built with formal verification patterns and undergoes regular third-party audits.
Reduced Compliance Overhead by 70%
Automate sanctions screening, entity verification, and risk scoring across Ethereum, Solana, Polygon, and other EVM/L1 chains with a single API, eliminating manual review processes.
Seamless Multi-Chain User Experience
Enable users to maintain a single, portable compliance score across networks. Integrate with our widget or API to onboard users 5x faster without sacrificing security checks.
Future-Proof Regulatory Alignment
Our scoring models and rule engines are continuously updated for MiCA, Travel Rule, and global AML directives. We handle the regulatory complexity so you can focus on product growth.
Enhanced Liquidity & Partner Access
Demonstrate provable compliance to centralized exchanges, liquidity providers, and institutional partners. Our attestations serve as a trust credential for enterprise integrations.

Our Delivery Methodology
We deliver your cross-chain compliance gateway through a structured, transparent process designed for security, speed, and seamless integration.
Compliance Architecture Review
We analyze your target chains (EVM, Cosmos, Solana), regulatory requirements, and risk models to design a scoring logic blueprint. This ensures your gateway aligns with OFAC, FATF Travel Rule, and jurisdiction-specific mandates from day one.
Secure Smart Contract Development
Our engineers build modular, upgradeable scoring contracts in Solidity 0.8+ and Rust, leveraging OpenZeppelin libraries and formal verification patterns. Each module is gas-optimized for on-chain execution.
Oracle & Data Feed Integration
We implement secure connections to real-time data sources—including Chainalysis, TRM Labs, and proprietary threat intelligence—via decentralized oracles (Chainlink, Pyth) for tamper-proof scoring inputs.
Cross-Chain Messaging Layer
Deployment of secure message-passing infrastructure using Axelar, LayerZero, or Wormhole to synchronize compliance states and scores across all supported blockchain networks.
Staging & Penetration Testing
Your gateway undergoes rigorous testing on testnets against simulated attack vectors and compliance scenarios. Includes a third-party smart contract audit from firms like CertiK or Quantstamp.
Production Deployment & Monitoring
We manage the mainnet deployment and provide a 24/7 monitoring dashboard for scoring accuracy, system health, and alerting. Includes SLAs for uptime and incident response.
Custom Blockchain Development
End-to-end blockchain solutions built for scale, security, and speed.
We architect and deploy custom Layer 1 & 2 blockchains, private enterprise networks, and application-specific rollups. Our full-stack engineering delivers production-ready infrastructure, not just proof-of-concepts.
- From Genesis: Design consensus (
PoS,PoA), tokenomics, and governance models. - To Mainnet: Full node deployment, RPC endpoints, block explorers, and wallets.
- Guaranteed Performance: Sub-2-second block times and 99.9% uptime SLA.
- Audit-Ready Code: Built with
Cosmos SDK,Substrate, orOP Stackfollowing security-first patterns.
Deploy a secure, scalable testnet in under 4 weeks. We handle the core protocol so you can focus on your application layer.
Frequently Asked Questions
Get clear answers on how our gateway integrates, secures, and scales your cross-chain operations.
Standard deployment takes 2-3 weeks from kickoff to production. This includes integration with your existing infrastructure, configuration of scoring rules, and a full security audit of the integration points. Complex multi-chain deployments with custom rule engines may extend to 4-5 weeks. We provide a detailed project plan with weekly milestones.
