Security for Crypto, DeFi & Web3
Cryptocurrency exchanges, DeFi protocols, and Web3 applications are high-value targets. We provide smart contract audits, protocol security assessments, and penetration testing built for the unique attack surface of blockchain-based platforms.
Why this sector gets targeted
The crypto and Web3 space has lost billions to exploits, rug pulls, and protocol vulnerabilities. Smart contract bugs have drained entire protocols in minutes. Bridge exploits have led to nine-figure losses. Exchange hot wallets have been compromised through social engineering and insider threats. The threat landscape is uniquely dangerous because transactions are irreversible, code is immutable once deployed, and attackers can profit instantly through flash loans and MEV extraction. Most Web3 projects ship fast and audit later - if they audit at all. The composability of DeFi means a vulnerability in one protocol can cascade across the entire ecosystem. Security testing is not optional in this space - it is existential.
Who we work with here
What we usually run
Scoped for this sector rather than sold as a catalogue. Each one is fixed scope with retest included.
Blockchain & Smart Contract Auditing
Line-by-line review of Solidity, Rust, and Move contracts for logic flaws and economic exploits.
How it runs →Web Application Penetration Testing
Your exchange frontend and user-facing dApp is a traditional web attack surface that needs testing.
How it runs →API Penetration Testing
Exchange and wallet APIs handle authentication, trading, and withdrawals - all high-value targets.
How it runs →Social Engineering & Phishing
Social engineering is the most common attack vector against exchange employees and protocol teams.
How it runs →Cloud Security Testing
Validate the cloud infrastructure running your nodes, APIs, and key management systems.
How it runs →Mobile Application Testing
Most exchanges and wallets have mobile apps that store keys and handle sensitive operations.

- Delivered security assessments for cryptocurrency media and exchange platforms
- Testing methodology covers OWASP Smart Contract Top 10 and traditional web/API attack surfaces
- Experience with Solidity, Rust, and EVM-compatible chain security
Asked on almost every call
We audit smart contracts on Ethereum and EVM-compatible chains (Polygon, Arbitrum, BSC, Avalanche), Solana (Rust/Anchor), and other major platforms. Our auditors have deep experience with DeFi protocol patterns, token standards, and cross-chain bridge architectures.
Yes. Most Web3 projects have a traditional web frontend, backend APIs, and smart contracts on-chain. We test the full stack because attackers target the weakest link - a secure smart contract means nothing if the frontend has an XSS vulnerability that can trick users into signing malicious transactions.
Depending on contract complexity, we can deliver initial findings within 1-2 weeks for smaller contracts and 2-4 weeks for complex DeFi protocols. We understand the pace of Web3 launches and can prioritize critical path reviews when time is tight.
Yes. We provide a formal audit attestation that can be shared publicly or with partners, investors, and listing platforms. This includes scope, methodology, findings summary, and remediation status.
Absolutely. Flash loan attacks, oracle manipulation, and economic exploits are core parts of our DeFi testing methodology. We model economic attack scenarios and test for composability risks that arise from your protocol interacting with other DeFi primitives.
