L2 Event Streaming API

A high-performance, low-latency API for subscribing to and streaming raw or structured events from Layer 2 chains. Engineered for high-frequency trading bots, real-time monitoring, and live dashboards.

overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by veteran Web3 engineers.

We architect and deploy custom smart contracts on EVM and Solana that are secure by design. Our development process integrates formal verification and automated testing to ensure reliability before your first user interacts with the protocol.

  • Production-Ready Code: Built with Solidity 0.8+ and Anchor, following OpenZeppelin standards and security best practices.
  • Comprehensive Audits: Every contract undergoes internal review and is prepared for third-party audits by firms like CertiK or Quantstamp.
  • Gas Optimization: We minimize transaction costs, achieving up to 40% gas savings on critical functions.
  • Full Lifecycle Support: From initial design and development to deployment, upgrade management, and ongoing maintenance.

Deploy battle-tested contracts in 2-4 weeks, not months. We deliver the foundational logic for your token, DeFi protocol, or NFT project with enterprise-grade security.
