Smart Contract Security Audits

Comprehensive security assessment service for smart contract code across multiple blockchain platforms including Ethereum, Solana, Polygon, and other EVM-compatible chains. The audit process combines manual code review by experienced blockchain security engineers with automated vulnerability scanning to identify critical security flaws including logic errors, reentrancy vulnerabilities, permission issues, and other common smart contract vulnerabilities.

Seven-Phase Audit Methodology

The audit approach includes:

1. Manual Code Review - Human-led analysis by senior security experts to identify complex security flaws and business logic vulnerabilities
2. Vulnerability Analysis - Comprehensive testing to ensure the code behaves as intended across different scenarios and edge cases
3. Automated Code Analysis - Running industry-standard automated security tools to detect known vulnerability patterns
4. Initial Audit Report - Providing a preliminary summary of the smart contract's security posture and identified issues
5. Development Revisions - Client's development team applies necessary fixes based on audit findings
6. Fixed-Code Analysis - Reviewing the updated smart contract code to confirm all issues are properly resolved
7. Final Audit Report - Delivering a detailed final report with severity classifications, remediation recommendations, and security certifications

DeFi & DApp Specialized Security

For decentralized applications and DeFi protocols, the audit extends beyond basic smart contract review to cover:

• DeFi Protocol Logic - Audit of lending/borrowing mechanisms, automated market makers (AMMs), yield farming contracts, staking systems, and liquidity pools
• Flash Loan Protection - Analysis and mitigation strategies for flash loan attacks that exploit single-transaction atomicity
• Price Manipulation Analysis - Review of oracle dependencies, price calculation mechanisms, and safeguards against price manipulation attacks
• MEV Considerations - Assessment of protocol vulnerability to front-running, sandwich attacks, and other MEV exploitation
• Frontend Security - Security review of web3 frontend code and wallet connection interfaces
• Wallet Integration Security - Review of wallet connection libraries, signature request flows, and transaction construction

Penetration Testing & Active Exploitation

Beyond static code audits, the service includes simulated attacks to actively identify vulnerabilities:

• Active exploitation attempts on deployed contracts in test environments
• Reentrancy attack simulations
• Economic attack simulations (flash loan attacks, oracle manipulation)
• Access control bypass testing
• Attack scenario documentation with proof-of-concept exploits

Languages & Platforms Supported

The team audits smart contracts written in Solidity (EVM chains), Rust (Solana, Polkadot), and other blockchain programming languages across multiple ecosystems.

Track Record

0xTeam maintains a 99.8% security success rate and has completed 132+ smart contract audits, secured over $2.3 billion in digital assets, and identified 5,900+ vulnerabilities across projects on Ethereum, Solana, Polygon, and other major blockchain platforms. Clients receive detailed, easy-to-understand audit reports with clear severity levels (critical, high, medium, low), specific remediation steps, and best practice recommendations, along with post-audit consultation calls to ensure development teams fully understand findings and remediation approaches.
