DeFi & DEX Security Audits
Secure Your Decentralized Finance Protocol Against Exploits
DeFi protocols manage billions of dollars in assets, making them the highest-value targets in blockchain. Codeum's specialized DeFi audits go beyond standard smart contract review to analyze economic attack vectors, oracle manipulation risks, and protocol-specific vulnerabilities that generic audits miss.

What is a DeFi Security Audit?
A DeFi security audit is a comprehensive review of decentralized finance protocols that goes beyond standard smart contract analysis. DeFi protocols are uniquely complex — they combine multiple smart contracts, rely on external price oracles, manage liquidity pools, and implement intricate economic mechanisms that can be exploited in ways that aren't apparent from code review alone.
Our DeFi auditors analyze your protocol's economic model, tokenomics, governance mechanisms, and integration with external protocols to identify both technical vulnerabilities and economic attack vectors.
Common DeFi Attack Vectors
DeFi protocols face unique attack vectors that require specialized audit expertise:
Flash Loan Attacks
Instant billion-dollar leverage
Flash loans allow attackers to borrow massive amounts of capital within a single transaction. We analyze your protocol's susceptibility to flash loan-enabled price manipulation, oracle attacks, and arbitrage exploits.
Oracle Manipulation
Price feed exploitation
DeFi protocols rely on price oracles for critical functions. We review your oracle integration for manipulation risks, stale price vulnerabilities, and single points of failure in price data sources.
Economic Exploits
Tokenomics & governance attacks
Beyond code vulnerabilities, DeFi protocols can be exploited through economic mechanisms — governance attacks, reward manipulation, and liquidity pool draining strategies that exploit protocol incentives.
DeFi Protocols We Audit
Our DeFi audit expertise covers the full spectrum of decentralized finance applications:
Decentralized Exchanges (DEXs): AMM logic, swap routing, liquidity pool management, and concentrated liquidity positions.
Lending & Borrowing: Collateral management, liquidation mechanisms, interest rate models, and flash loan integration.
Yield Aggregators: Vault strategies, reward compounding, harvest mechanics, and strategy contract security.
Stablecoins: Peg maintenance mechanisms, collateral backing, minting/burning logic, and governance controls.
Derivatives & Synthetics: Perpetual contracts, synthetic asset minting, funding rate mechanisms, and liquidation engines.
Our DeFi Audit Methodology

Frequently Asked Questions
How is a DeFi audit different from a regular smart contract audit?
A DeFi audit includes all aspects of a standard smart contract audit plus additional analysis of economic mechanisms, oracle integrations, governance security, and protocol-specific attack vectors like flash loan exploits and liquidity manipulation.
How long does a DeFi audit take?
DeFi audits typically take 2-4 weeks depending on protocol complexity. Simple DEX or lending protocols may be faster, while complex multi-contract systems with extensive integrations require more time.
Do you audit protocols on multiple chains?
Yes, we audit DeFi protocols on Ethereum, BSC, Polygon, Arbitrum, Avalanche, and other EVM-compatible chains. Many DeFi protocols deploy across multiple chains, and we can audit all deployments.
Can you audit protocols that are already live?
Yes, we audit both pre-launch and live protocols. For live protocols, we can identify vulnerabilities and recommend upgrade strategies using proxy patterns or migration plans.
What if an exploit happens after the audit?
We provide post-audit support including re-verification of fixes and can assist with incident analysis if an exploit occurs. Our goal is to be a long-term security partner, not just a one-time auditor.
