Your Code Handles Money. We Make Sure It Holds.
Smart contract security audits across EVM, Solana, Cosmos, Move, and ZK circuits. Seven specialized AI auditors. Human oversight on every engagement. Powered by Viper, our internal audit toolkit.
[ Request an Audit ]What We Audit
From token contracts to complex cross-chain protocols. If it's on-chain and handling value, we tear it apart before someone else does.
EVM Smart Contracts
Solidity, Vyper, and everything deployed on Ethereum and L2s. Token standards, staking, vesting, governance, custom protocol logic. Viper was built for this. It's where we started and where we hit hardest.
Solana Programs
Rust and Anchor programs audited by Mamba, our Solana specialist. Account validation, CPI security, PDA handling, and the Solana-specific footguns that generic auditors miss entirely.
DeFi Protocols
AMMs, lending markets, bridges, vaults, yield aggregators, liquidity management. Cobra maps the full attack surface, including off-chain components, oracle dependencies, and economic exploit vectors.
Cross-Chain Bridges
Bridge contracts and cross-chain messaging between any supported chains. Message verification, relay security, asset lockup logic. Bridges are the highest-value targets in crypto. We audit them like it.
Cosmos & Move Contracts
Cosmos SDK modules in Go (Krait) and Move contracts on Sui and Aptos (Taipan). Dedicated auditors for ecosystems that most firms bolt on as an afterthought.
ZK Circuits
Circom, Noir, and Halo2 circuits audited by Asp. Constraint validation, soundness verification, and the subtle circuit bugs that slip past teams who treat ZK as "just math." It's math that guards millions.
Powered by Viper
Our Smart Contract Audit Toolkit
Viper combines static analysis, pattern matching, and AI-powered vulnerability detection into a single automated pipeline. It runs against every codebase before any auditor touches it.
Known vulnerability patterns, custom detection rules, cross-function data flow analysis. Viper catches what off-the-shelf scanners miss, and it gives our auditors a head start so they can focus on the logic bugs that only a trained eye finds.
Case Study Coming SoonMeet the Squad
HexIT Security: 7 Auditors. Every Chain Covered.
Orchestrates every audit. Scopes engagements, assigns the right auditors, synthesizes findings into the final report. Nothing ships without Venom's sign-off.
The workhorse. Core EVM auditor handling Solidity and Vyper contracts. Static analysis, manual review, and deep knowledge of every known exploit pattern on Ethereum and L2s.
Solana-native auditor. Rust, Anchor, and the full Solana runtime model. Catches the account confusion, missing signer checks, and CPI vulnerabilities that EVM auditors wouldn't even know to look for.
DeFi protocol specialist with web and API reconnaissance capabilities. Maps economic attack vectors, oracle manipulation paths, and off-chain dependencies. Thinks like an attacker, not a checklist.
Cosmos module auditor. Go-native, IBC-aware, and built for the Cosmos ecosystem. Validator logic, governance modules, and cross-chain message handling.
Sui and Aptos specialist. Move's resource model is different from everything else, and Taipan was built specifically for it. Object ownership, capability patterns, and Move-specific edge cases.
Circom, Noir, and Halo2. Constraint system analysis, under-constrained circuit detection, and soundness verification. The auditor you need when a single missing constraint can drain a protocol.
Audit Process
Automated tooling plus specialist review. Every finding classified, documented, and shipped with remediation guidance. No ambiguity.
Scoping
Review codebase, map protocol architecture, identify the right auditors for your stack. Lock audit scope. Fixed price. No surprises.
Automated Scan
Viper runs static analysis, pattern matching, and known vulnerability detection across your entire contract surface. Results feed directly into manual review.
Manual Review
Specialized AI auditors go line-by-line on their domain. Business logic vulnerabilities, edge cases, economic exploits. Each auditor focuses on what they know best.
Report
Detailed findings with severity classification and specific remediation steps. Every vulnerability documented with proof-of-concept and fix guidance. Actionable, not academic.
Remediation & Re-Audit
We work with your team to verify fixes. Or we implement fixes ourselves. Either way, remediated code gets a full re-audit pass. Nothing ships until it's clean.
Supported Chains
Deep expertise across the platforms that matter. Dedicated auditors for every ecosystem.
The gold standard. Production contracts securing billions in TVL.
Coinbase's L2. Low fees, high throughput. Ideal for consumer DeFi.

Tech Stack
Battle-Tested
Our auditors have competed in bug bounty contests on the platforms that matter. The same techniques that find vulnerabilities in live protocols are the ones we run against yours before it ships.
Competitive audit contests against top security researchers. Real protocols, real stakes, ranked results.
Community-driven audit competitions. Complex DeFi protocols dissected by hundreds of wardens simultaneously.
The largest bug bounty platform in crypto. Responsible disclosure on live protocols securing billions in TVL.
