COMPREHENSIVE AUDIT SCOPE
What Our Migration Security Assessment Covers
Our structured assessment delivers a detailed, actionable report, not just a checklist. We identify critical vulnerabilities, architectural risks, and business logic flaws to ensure your migration is secure and reliable.
01
Smart Contract Code Review
Line-by-line analysis of your new and legacy contracts for security vulnerabilities, gas inefficiencies, and adherence to best practices. We check for reentrancy, overflow, access control flaws, and logic errors using both automated tools and manual review.
100%
Code Coverage
OWASP Top 10
Vulnerability Check
02
Upgrade Mechanism & Proxy Security
In-depth audit of your upgrade pattern (e.g., UUPS, Transparent Proxy). We verify initialization security, storage collision risks, admin privilege management, and ensure the upgrade process is resilient to front-running and unauthorized calls.

03
State & Storage Migration Validation
Verification that all critical data (user balances, permissions, contract state) is accurately and completely migrated. We simulate the migration to detect data corruption, loss, or inconsistencies that could break core functionality.
100%
Data Integrity Check
Dry-Run Simulation
Pre-Migration Test
04
Integration & Dependency Analysis
Assessment of external dependencies like oracles (Chainlink), DeFi protocols, and cross-chain bridges. We ensure your new contracts interact securely with external systems and that no breaking changes are introduced.

05
Economic & Incentive Security
Analysis of tokenomics, fee structures, and incentive mechanisms within the new system. We identify potential economic attacks, such as flash loan exploits, reward manipulation, or unsustainable emission schedules.

Final Verification & Action Plan
Delivery of a prioritized report with severity ratings (Critical, High, Medium, Low) and concrete remediation steps. Includes a re-audit of fixes and a final sign-off to give your team confidence for mainnet deployment.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy the foundational logic for your dApp, token, or DeFi protocol. Our team delivers audit-ready code in Solidity or Rust, implementing industry standards like ERC-20, ERC-721, and custom business logic with a focus on security and gas optimization.
From a 2-week MVP to a complex multi-chain system, we ensure your contracts are reliable, upgradeable, and secure from day one.
- Full Development Lifecycle: Design, development, testing, and deployment on mainnet or testnet.
- Security-First Approach: Built with
OpenZeppelinlibraries and patterns, prepared for third-party audits. - Gas Optimization: Every line of code is reviewed to minimize transaction costs for your users.
- Post-Deployment Support: Verification, monitoring, and upgrade management for live contracts.

Migration Security Assessment FAQs
Get clear answers on our process, timeline, and security guarantees for migrating your smart contracts to a new chain or version.
We follow a structured, three-phase methodology:
- Discovery & Scoping: We analyze your existing contracts, the target environment (e.g., new chain, compiler version), and the migration plan to define the assessment scope.
- Comprehensive Analysis: Our team performs manual code review, automated vulnerability scanning, and differential analysis to compare pre- and post-migration logic for unintended side effects, state corruption risks, and integration flaws.
- Reporting & Remediation: You receive a prioritized risk report with actionable fixes, gas optimization suggestions, and a final verification audit of the corrected migration code before deployment.
