CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment, verification, and on-chain monitoring. - Security-First Approach: Every contract undergoes manual review, automated testing, and passes audits from firms like CertiK or Quantstamp.
- Gas Optimization: We write efficient code to minimize transaction costs, critical for high-volume
DeFiandNFTapplications. - Compliance & Upgradability: Build with
ERC-20,ERC-721, or custom standards, featuring upgradeable proxy patterns for future-proofing.
Deliver a secure, audited, and fully functional smart contract system in as little as 4-6 weeks, ready for mainnet launch.

TRANSPARENT METHODOLOGY
Our Delivery Process: From Fork to Final Report
We provide a deterministic, step-by-step process for simulating and analyzing the impact of smart contract upgrades, delivering actionable intelligence to de-risk your protocol changes.
01
1. Environment Fork & State Capture
We fork the target blockchain at a specified block height, capturing the complete on-chain state of your protocol, including user balances, liquidity pools, and governance parameters, to create a perfect simulation sandbox.

Frequently Asked Questions
Get clear answers about how our simulation service identifies risks and ensures seamless protocol upgrades.
Our simulator creates a forked replica of your mainnet environment to test upgrades in isolation. We deploy your new contract version, execute a comprehensive suite of state and transaction simulations, and analyze the results against your existing protocol logic. This process identifies state variable conflicts, permission errors, and gas inefficiencies before any real deployment, providing a detailed impact report.
