EVM Transaction Monitoring System

A custom-built, real-time monitoring and alerting system for Ethereum and EVM-compatible chains. We develop systems that detect suspicious transaction patterns, screen against sanctions lists, and generate audit-ready compliance reports for financial authorities.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that power your token, DeFi protocol, or NFT collection. Our development process is built on security-first principles and proven patterns.

  • From Concept to Mainnet: We handle the full lifecycle—specification, development, testing, and deployment.
  • Security Audits: Every contract undergoes rigorous internal review and is built for external audits by firms like CertiK or OpenZeppelin.
  • Gas Optimization: We write efficient code to minimize transaction costs for your users.
  • Protocol Standards: Expertise in ERC-20, ERC-721, ERC-1155, and custom implementations for DeFi (AMMs, staking, lending).

Deliver a secure, auditable, and gas-efficient foundation for your on-chain product in as little as 2-4 weeks.

  • Mainnet Launch Support: Comprehensive go-live planning, including genesis configuration and ecosystem bootstrapping.
For Technical Decision Makers

EVM Transaction Monitoring: Key Questions

Common questions from CTOs and engineering leads evaluating enterprise-grade transaction monitoring solutions for EVM chains.

Typical deployment is 2-3 weeks from kickoff to production. This includes environment setup, custom alert configuration, and integration with your existing dashboards (Datadog, PagerDuty, Slack). For urgent needs, we offer a rapid deployment track that can get core monitoring live in under 7 days.
