EVM Smart Contract Penetration Testing

Adversarial attack simulation and manual exploit discovery targeting Ethereum and EVM-compatible smart contracts. We uncover critical vulnerabilities that automated scanners miss before they are exploited in production.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists to power your protocol.

We architect and deploy custom, gas-optimized smart contracts for DeFi, NFTs, and enterprise applications. Our development process ensures security-first code with comprehensive audits and formal verification.

From concept to mainnet, we deliver contracts that are secure, scalable, and ready for high-value transactions.

  • End-to-End Development: Full lifecycle from technical design to deployment on EVM/Solana/Cosmos.
  • Security Guarantee: Built with OpenZeppelin standards and subjected to third-party audits before launch.
  • Gas Optimization: Contracts engineered for minimum execution cost, saving users thousands in fees.
  • Real-World Results: Deployed contracts handling $500M+ in TVL with 99.9% uptime.

PROVEN FRAMEWORK

Our Adversarial Testing Methodology

Our systematic, multi-layered approach simulates real-world attacks to uncover critical vulnerabilities before they are exploited. We go beyond automated scanners with manual, adversarial thinking.

01

Comprehensive Threat Modeling

We begin by mapping your contract's attack surface, identifying privileged roles, value flows, and external dependencies to prioritize testing on the highest-risk areas.

Attack Surface Mapped
OWASP Top 10

02

Manual Code Review & Logic Flaws

Senior auditors perform line-by-line analysis of business logic, access controls, and financial math to find flaws automated tools miss, like reentrancy or improper state handling.

03

Dynamic Fuzzing & Invariant Testing

We deploy custom fuzzers and property-based tests (using Foundry/Chaos) to bombard your contracts with random inputs, breaking invariants and uncovering edge-case failures.

Formal Verification (Optional)

For critical financial logic, we apply mathematical proofs to verify that contract behavior matches its specification, guaranteeing the absence of whole classes of bugs.

BEYOND AUTOMATED SCANS

Why Manual Penetration Testing is Critical

Automated tools can only find known vulnerabilities. Our expert-led manual testing uncovers the logic flaws, economic exploits, and architectural weaknesses that automated scanners miss, securing your protocol's core value.

01

Uncover Complex Logic Flaws

Our security engineers manually trace execution paths to find reentrancy, access control bypasses, and business logic errors that static analysis cannot detect.

Simulate Sophisticated Adversaries

We employ advanced techniques like flash loan attack simulations, oracle manipulation, and MEV extraction to test your contract's resilience under real-world economic pressure.

Validate Economic Security

Manual review ensures tokenomics, fee structures, and incentive mechanisms are sound, preventing exploits that could drain treasury funds or destabilize your protocol.

Ensure Integration Security

We test the entire interaction surface—including cross-contract calls, bridge integrations, and oracle dependencies—to prevent vulnerabilities at the system level.

Choosing the Right Security Approach

Automated Scan vs. Manual Penetration Test

While automated tools provide a valuable first pass, manual expert analysis is critical for uncovering complex logic flaws and business logic vulnerabilities that automated scanners miss. This table compares the scope and depth of each approach.
