We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our contracts are built for security first, using battle-tested patterns from OpenZeppelin and rigorous internal audits.
Cross-Chain Payment Fraud Detection System
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- From 2-week MVP to complex DeFi protocol logic.
- Gas-optimized code for lower transaction costs.
- Full testing suite with
HardhatorFoundry. - Upgradeability planning using proxies or immutable designs.
We deliver auditable, maintainable code that forms the trusted foundation of your application.
Core Detection Capabilities
Our system analyzes cross-chain transaction patterns to identify and block sophisticated fraud before it impacts your treasury. We deliver actionable intelligence, not just alerts.
Anomaly & Sybil Attack Detection
Identifies coordinated wallet clusters and abnormal transaction patterns indicative of Sybil attacks, wash trading, and fake liquidity across EVM and non-EVM chains.
Bridge & MEV Exploit Monitoring
Continuously monitors for signature exploits, slippage manipulation, and malicious MEV bundles targeting cross-chain bridges and DEX aggregators.
Address Reputation & Risk Scoring
Dynamic risk scoring for every wallet based on on-chain history, association with mixers, sanctioned entities, and involvement in past exploits.
Smart Contract Vulnerability Alerts
Proactive detection of reentrancy, logic flaws, and access control issues in destination chain contracts before funds are released.
Business Outcomes for Your Bridge
Our Cross-Chain Payment Fraud Detection System delivers measurable security and operational improvements, directly impacting your bridge's bottom line and user trust.
Real-Time Threat Neutralization
Detect and block fraudulent cross-chain transactions before they are finalized, preventing fund loss and protecting user assets across all connected chains.
Reduced Operational Overhead
Automate manual monitoring and investigation workflows. Our system flags only high-risk events, allowing your security team to focus on strategic initiatives.
Enhanced User Trust & Retention
Proven security builds confidence. Publicly verifiable protection metrics and audit trails demonstrate your commitment to safeguarding user funds, reducing churn.
Lower Insurance & Risk Costs
Demonstrate robust, proactive security controls to underwriters. Our system provides the audit trails and compliance reporting needed to secure favorable coverage terms.
Faster Incident Response
Gain immediate, actionable intelligence on attack vectors. Our detailed forensic reports and chain-agnostic tracing accelerate investigation and recovery processes.
Future-Proof Security Posture
Our detection models are continuously updated for emerging threats (e.g., bridge-specific exploits, novel MEV attacks), ensuring long-term protection as you scale.

Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy audited, gas-optimized smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our process ensures zero critical vulnerabilities and up to 40% gas savings on high-frequency operations.
- Full Lifecycle Development: From specification and
Solidity/Rustcoding to deployment and upgrade management. - Security-First: Rigorous testing with Foundry/Hardhat, integration of
OpenZeppelinstandards, and preparation for third-party audits. - Compliance & Features: Custom logic for
ERC-20,ERC-721, staking, governance, and cross-chain bridges.
Technology & Protocol Coverage
Our fraud detection system is built on deep, protocol-native integrations, ensuring accurate transaction analysis and threat identification across the entire Web3 payment landscape.
Frequently Asked Questions
Get clear answers on how our real-time fraud detection system integrates, scales, and protects your payment infrastructure.
Our system uses a multi-layered detection engine that analyzes transaction patterns, wallet behaviors, and cross-chain message flows in real-time. We deploy custom detection rules for each supported chain (Ethereum, Solana, Polygon, Arbitrum, etc.) and correlate activity across them using our proprietary risk-scoring algorithm. This identifies anomalies like wash trading, flash loan attacks, and bridge exploits with over 99.5% accuracy and sub-second latency.
