overview
CORE SERVICE

Smart Contract Development

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

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

  • Full-Stack Development: From ERC-20 tokens to complex DeFi protocols and NFT marketplaces.
  • Security & Auditing: Built with OpenZeppelin standards, followed by rigorous internal review and preparation for third-party audits.
  • Integration & Deployment: Seamless integration with frontends and deployment to mainnet or testnets with automated CI/CD pipelines.

Deliver a secure, auditable, and high-performance smart contract system in as little as 2-4 weeks for an MVP.

BUILT FOR PRODUCTION

Core Capabilities of Your Custom Simulator

Our EVM transaction simulators are engineered for reliability and precision, providing the deterministic testing environment your team needs to ship with confidence.

01

Deterministic State Forking

Fork any EVM mainnet or testnet at a specific block. Test your dApp's logic against real, historical on-chain state to catch edge cases before deployment.

Business Outcomes: Beyond Code

Our EVM Transaction Simulator development delivers more than just a tool—it provides a strategic advantage. We build systems that directly impact your product's reliability, security, and time-to-market.

01

Pre-Production Risk Elimination

Identify and resolve transaction failures, gas spikes, and edge-case vulnerabilities before deployment. We integrate with your CI/CD pipeline to catch issues that unit tests miss, preventing costly mainnet errors.

PROVEN PROCESS

Our Development Methodology

We build EVM transaction simulators through a rigorous, security-first engineering process designed for production-grade reliability and rapid deployment.

01

Architecture & Design Review

We begin with a collaborative deep-dive into your specific use case—whether for DeFi risk analysis, wallet previews, or protocol testing. Our team designs a modular architecture using battle-tested patterns for fork management, state simulation, and gas estimation.

02

Core Engine Development

Our engineers build the simulation engine using hardened libraries like ethers.js/viem and custom RPC handlers. We implement deterministic forking from archival nodes (Alchemy, QuickNode), precise gas tracking, and state rollback mechanisms to ensure accurate, repeatable results.

Security & Testing Rigor

Every component undergoes exhaustive testing. We implement unit tests for core logic, integration tests against live forked networks (Ethereum, Polygon, Arbitrum), and fuzz testing for edge cases. Security reviews are conducted to prevent state corruption or injection vulnerabilities.

Frequently Asked Questions

Get clear answers on our development process, security, and delivery for custom EVM transaction simulators.

Standard deployments take 4-6 weeks from kickoff to production-ready delivery. This includes 1 week for requirements & architecture, 2-3 weeks for core development and integration, and 1 week for security review and deployment. Complex features like multi-chain support or advanced gas estimation can extend this to 8-10 weeks. We provide a detailed sprint-by-sprint timeline in our initial proposal.
