overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our process ensures security-first development with formal verification and comprehensive audits before mainnet launch.

  • End-to-End Development: From ideation to deployment on EVM-compatible chains (Ethereum, Polygon, Arbitrum).
  • Security Audits: Multi-stage reviews using Slither and MythX, plus third-party auditor coordination.
  • Gas Optimization: Achieve up to 40% lower transaction costs through efficient code patterns and storage design.
  • Upgradeability: Implement secure proxy patterns (TransparentProxy, UUPS) for future-proof contracts.

We deliver battle-tested code that handles real value, with a zero critical-bug track record in production.

Business Outcomes for Your dApp

Our MEV-Resistant Transaction API delivers concrete technical and commercial advantages, directly impacting your dApp's security, user experience, and bottom line.

01

Eliminate Front-Running & Sandwich Attacks

We implement private transaction pools, encrypted mempools, and strategic timing to shield your users' trades from predatory MEV bots. This directly protects user funds and ensures fair execution prices.
