overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM and Solana that form the foundation of your Web3 product. Our development process is built for security-first execution and long-term maintainability.

  • Full Lifecycle Development: From initial specification and Solidity/Rust coding to deployment and on-chain verification.
  • Security by Design: Contracts are built with OpenZeppelin standards, undergo rigorous internal audits, and are prepared for third-party review.
  • Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol economics.

We deliver auditable, upgradeable contracts that power everything from DeFi protocols to enterprise NFT platforms.

Our team specializes in complex contract systems:

  • DeFi Primitives: Custom AMMs, lending/borrowing pools, yield aggregators, and derivative contracts.
  • Token Standards: ERC-20, ERC-721, ERC-1155, SPL, and custom implementations with advanced features like vesting and governance.
  • Cross-Chain & Modular: Bridge integrations, layer-2 deployments on Arbitrum/Optimism, and modular architecture for future upgrades.
