DeFi Security Audit
Protect Your Protocol

Specialized security audits for DeFi protocols. Expert analysis of AMM, lending pools, yield farming, and governance contracts. Protect your users and funds from DeFi-specific vulnerabilities with our comprehensive audit solution.

What is a DeFi security audit?

  • →A DeFi audit reviews AMM, lending, staking, and governance contracts for attack vectors specific to decentralized finance — flash loans, oracle manipulation, and economic exploits that standard code audits miss.
  • →DeFi protocols lost $1.3 billion in H1 2026 — up 28% from H1 2025 (TRM Labs). This week alone: Ostium $23.75M (oracle key), AFX Trade $24.15M (bridge keys), Verus Bridge $7.54M (missing value check, second exploit of same bug).
  • →The most common attack classes today: off-chain key compromise, bridge validator key theft, and missing cross-chain value validation. AI-powered DeFi auditing catches the on-chain patterns instantly.

DeFi Audit FAQs

What is a DeFi security audit?
A DeFi security audit is a specialized review of decentralized finance smart contracts for vulnerabilities specific to AMMs, lending pools, staking systems, and governance contracts. Unlike a standard smart contract audit, a DeFi audit must also check for flash loan attack vectors, oracle manipulation risks, MEV exposure, and economic exploit paths that only exist in multi-protocol DeFi environments.
What vulnerabilities does a DeFi audit check for?
DeFi-specific vulnerabilities include: flash loan attacks, oracle price manipulation, reentrancy in lending pool callbacks, impermanent loss edge cases, liquidity pool invariant violations, governance vote manipulation, slippage control bypass, interest rate model exploits, reward calculation errors, and cross-chain bridge validation gaps. Standard checks (access control, integer overflow, reentrancy) also apply.
How much does a DeFi audit cost?
Traditional DeFi audits from firms like Trail of Bits, Zellic, or Pashov cost $20,000–$150,000+ and take 4–12 weeks depending on protocol complexity. AI-powered DeFi auditing at SmartContractAuditor.ai starts at $29 and delivers instant analysis. AI covers known vulnerability patterns; complex DeFi protocols should use AI as a first layer, then follow up with a manual audit for novel economic logic.
What's the difference between a DeFi audit and a standard smart contract audit?
A standard smart contract audit checks code-level vulnerabilities: reentrancy, integer overflow, access control. A DeFi audit adds economic and protocol-level analysis: can an attacker use a flash loan to manipulate prices? Is the AMM invariant valid under adversarial conditions? Does the oracle update before or after state changes? These questions require DeFi domain knowledge, not just code review.
How long does a DeFi audit take?
With SmartContractAuditor.ai, AI-powered DeFi analysis is instant — results in under 30 seconds. Traditional DeFi audits take 4–12 weeks depending on protocol complexity and firm availability. Top firms (Zellic, Pashov, Sherlock) have waitlists of 2–4 months. AI auditing works best as a first pass before scheduling a manual audit.
Can AI replace a DeFi security audit?
AI-powered auditing reliably catches known vulnerability patterns: reentrancy, access control, oracle single-source dependence, missing slippage checks. It struggles with novel economic logic and off-chain infrastructure — Ostium's $23.75M loss in July 2026 was an off-chain oracle signer key compromise that no Solidity audit covers. The right model: use AI for fast, affordable first-pass coverage, then follow with a manual audit before mainnet deployment.
