SECURE FOUNDATIONS
Custom Smart Contract Development
Production-ready smart contracts built with enterprise-grade security and gas optimization.
- Multi-protocol Expertise:
EVM(Ethereum, Polygon, Arbitrum),Solana,Cosmos SDK, andMove(Aptos, Sui). - Security-First Development: Adherence to
OpenZeppelinstandards, automated testing withFoundry/Hardhat, and integration withSlither/MythX. - Gas Optimization: Code reviewed for efficiency, reducing user transaction costs by up to 40% on average.
From tokenomics (
ERC-20,ERC-721,ERC-1155) to complex DeFi primitives, we build the immutable logic that powers your business.

COMPREHENSIVE SECURITY REVIEW
What We Audit in Your AA Stack
Our audit methodology systematically examines every critical component of your Account Abstraction infrastructure, from core smart contracts to user experience safeguards. We deliver actionable reports that prioritize high-severity risks and provide clear remediation guidance.
01
Account & EntryPoint Contracts
In-depth analysis of your custom SmartAccount and EntryPoint implementations for ERC-4337 compliance, reentrancy risks, and gas optimization. We verify proper signature validation, nonce handling, and paymaster integration.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our code is built for security first, using OpenZeppelin libraries and following ERC-20, ERC-721, and ERC-1155 standards.
Deliver a battle-tested contract suite in 2-4 weeks, not months.
- Full-Stack Development: From tokenomics design to deployment and frontend integration.
- Security & Audits: Rigorous internal review, with optional integration for third-party audits from firms like CertiK or Quantstamp.
- Gas Optimization: Write efficient code to reduce user transaction costs by up to 40%.
- Post-Launch Support: Upgradeability planning, monitoring, and maintenance.

Account Abstraction Audit FAQs
Get clear answers on our audit process, timeline, pricing, and security methodology for your Account Abstraction (ERC-4337) project.
Our audit follows a rigorous, multi-stage methodology tailored for ERC-4337 complexity. We conduct manual code review focusing on EntryPoint, Paymasters, Account factories, and custom logic. This is complemented by automated analysis using Slither and Foundry for invariant testing, and formal verification for critical state transitions. We test against the official ERC-4337 bundler test suite and simulate complex user operation flows, including gas sponsorship, batched transactions, and signature validation.
