overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our process ensures security-first development, gas optimization, and full audit readiness from day one.

  • Custom Logic: Build ERC-20, ERC-721, ERC-1155, or bespoke token standards.
  • DeFi Protocols: Develop lending/borrowing pools, automated market makers (AMMs), and yield strategies.
  • NFT Ecosystems: Create minting contracts, marketplaces, and dynamic metadata systems.
  • Governance & DAOs: Implement voting mechanisms, treasury management, and proposal systems.

We deliver battle-tested code that passes rigorous security reviews, reducing your time-to-audit by 50%.

Our development lifecycle includes:

  • Formal Specification: Documenting logic and edge cases in a technical spec.
  • Iterative Development: Using Solidity 0.8+ with Hardhat or Foundry frameworks.
  • Comprehensive Testing: Unit, integration, and scenario testing with >95% coverage.
  • Deployment & Verification: Mainnet deployment with full source code verification on Etherscan.

PROVEN PROCESS

Our Integration Methodology

A structured, four-phase approach to ensure your AA integration is secure, scalable, and delivered on time. We focus on measurable outcomes, not just deployment.

01

Architecture & Strategy

We analyze your use case and design a custom AA architecture. We select the optimal SDK (Biconomy, ZeroDev, or custom) and define gas sponsorship models, key management, and user flow.

Custom Smart Contract Development

Production-ready smart contracts built with enterprise-grade security and gas optimization.

We architect, develop, and audit custom Solidity/Rust smart contracts for DeFi, NFTs, and enterprise applications. Our focus is on security-first development, gas-efficient execution, and maintainable code that scales with your protocol.

  • Zero Critical Bugs: All code undergoes rigorous internal review and third-party audits from firms like CertiK or Quantstamp.
  • Gas Optimization: We achieve 20-40% lower transaction costs through advanced optimization patterns.
  • Full-Suite Support: From ERC-20/ERC-721 tokens to complex DeFi primitives like AMMs and lending vaults.

Deploy with confidence. We deliver battle-tested contracts that secure millions in TVL, reducing your time-to-audit by weeks and mitigating catastrophic financial risk.
