🚨 VectorGuard Labs: Adversarial Smart Contract Security

Adversarial Pre-Audit Security Assessments for Web3 Protocols

Why VectorGuard Labs Exists

Web3 protocols are attacked by real adversaries: MEV searchers, flash loan attackers, oracle manipulators, governance abusers, and not by linters. Traditional audits often stop at static analysis, pattern matching, and PDF reports. They rarely behave like an attacker trying to break your protocol on a forked mainnet and prove it with a TX hash.

VectorGuard Labs delivers adversarial pre-audit security assessments using its 15-Phase Framework + 338-vector attack library to stress, break, and validate your protocol before you ever talk to a Tier-1 audit firm.

🔥 What Makes Us Different?

Adversarial, Evidence-First Mindset

We don’t just “review code” - we attempt to break it using the VectorGuard Labs 15-phase methodology, then back every Critical/High finding with exploit scripts, execution traces, and attacker balance deltas.

338 Real-World Attack Vectors

Reentrancy, MEV, oracle and bridge manipulation, governance capture, rounding and accounting drift, AA/EIP-4337, hooks, cross-chain desyncs, economic attacks, and more, modeled from billions of dollars in real exploits.

Exploit-Backed Findings

Every meaningful finding includes root cause analysis, exploit narrative, reproduction steps, and (when feasible) a fork-based PoC that shows before/after balances, invariant violation, and protocol state diffs.

Risk-Based, Time-Disciplined Execution

We prioritize attack paths that can actually kill your protocol or users, combining automated tooling, invariant testing, and exploit development into a tight, goal-driven engagement window.

Pre-Audit, Not Audit

We don’t compete with firms like Trail of Bits, OpenZeppelin, Certik, or Cyfrin. We prepare you for them so formal auditors see a hardened codebase, real exploit coverage, and a protocol that takes security seriously.

🧪 Our Validation & Exploit Approach

Semantic & Invariant-Driven Analysis

We model what your protocol is supposed to do, then define hard invariants around solvency, share accounting, access control, cross-chain state, and economic safety and attempt to violate them.

Automated Analysis & Fuzzing

Static analysis, mutation tests, symbolic execution, stateless and stateful fuzzing, property tests, and invariant tests across high-risk flows to push your contracts into weird, adversarial edge cases.

DeFi Attack Surface Coverage

Coverage across lending, AMMs, vaults, staking, governance, liquidations, LSTs, AA, hooks, and bridges mirroring how real attackers chain protocols together for maximum impact.

Fork-Based Attack Simulation

Where chains support it, we use mainnet forks (or their equivalents) to simulate attacks with real liquidity, oracle feeds, and gas constraints, capturing TX hashes and execution traces as proof.

Economic & Game-Theoretic Modeling

We analyze profitability and incentives for rational attackers, flash loan windows, oracle manipulation profit, governance capture ROI, and long-horizon economic attacks.

Integration & Cross-Chain Risk

We investigate how your protocol can be broken via integrated protocols, bridges, oracles, AA, and hooks not just within your own repo.

✅ Benefits for Your Protocol

  • Identify Critical and High impact paths that could realistically drain funds, corrupt state, or kill the protocol.
  • Enter formal audits with fewer surprises, cleaner code, and exploit-backed pre-audit coverage reducing iteration and cost.
  • Build real security credibility with investors, formal auditors, and users by demonstrating adversarial testing, not just “we were audited.”
  • Receive concrete remediation guidance, exploit scripts, and invariants your team can harden against and reuse in future testing.

🔥 The VectorGuard Labs 338-Vector Attack Framework

Our pre-audit assessments are driven by the VectorGuard Pro 15-Phase Framework and a 338-vector attack library built from real exploits, not theory.

🎯 Phase 1 - 5
1. Manual review, map architecture, identify roles/permissions, and analyze upgradeability patterns to understand how value and authority flow through the system.
2. Identify threat actors (MEV, flash loan attackers, malicious integrators) and explicitly document and challenge all trust assumptions.
3. Formally define measurable security invariants (Financial, Access Control, State Consistency, Cross-Chain, Governance) that must never be violated.
4. Run automated tools, perform line-by-line manual review, hunt for known vulnerability classes, and implement invariant-based fuzzing to expose hidden paths to invariant breaks.
5. Fork-based (or chain-appropriate) exploit testing for Critical/High findings, generating full exploit scripts and transaction identifiers with attacker balance deltas, state diffs, and rigorous false positive filtering.
🎯 Phase 6 - 10
6. Model the protocol's intended behavior using functional specifications, state-machine diagrams, and Pre/Post Conditions to expose spec gaps and mismatches with the code.
7. Analyze rational attacker incentives, arbitrage paths, flash loan profitability, and multi-step economic attacks to determine which exploits are truly viable and profitable.
8. Perform gas profiling, unbounded loop detection, and gas-griefing analysis to identify DoS and griefing vectors that can make your protocol unusable or ungovernable.
9. Simulate multi-user interactions, race conditions (front-running/back-running), time-advanced scenarios, and use stateful/stateless fuzzing to recreate complex real-world dynamics.
10. Combine two or more vulnerabilities or “low-risk” issues into full red-team attack chains that can escalate to Critical impact, including profit and feasibility calculations.
🎯 Phase 11 - 15
11. Verify fixes, check for regressions, analyze new attack surfaces introduced by changes, and confirm storage layout stability for upgradeable contracts.
12. Prove/disprove critical properties using formal techniques (symbolic execution, property-based testing, and assertions) for mathematical-style assurance where appropriate.
13. Apply a strict severity classification and reporting standard, documenting each finding with root cause, exploitability, impact, and quantified risk where possible.
14. Perform a final coverage and risk review—reassessing severities, cross-checking attack surfaces, and ensuring the assessment maps clearly to your protocol’s threat model.
15. Generate a detailed, adversarially-informed report bundle and hand off to your team as a pre-audit hardening package to prepare for formal third-party audits.

Framework derived from thousands of real-world exploits • Continuously updated as new attack patterns and ecosystems emerge

✅ Why You Can Trust VectorGuard Labs Assessments

Unlike speculative scanners or AI-driven tools that exaggerate risk, VectorGuard Labs operates on a strict validated-only reporting model.

  • No fabricated vulnerabilities. If an exploit is not proven or demonstrable, it does not enter your report.
  • No severity inflation. Findings must be economically and technically viable to be considered real.
  • No theory-only issues. Missing features or stylistic disagreements are not misrepresented as vulnerabilities.
  • No “busywork reports.” If a protocol is sound, we explicitly state: “No Actionable Risks. Ready for Formal Audit.”

This guarantee is enforced through our Phase-0 grounding logic, proof-first methodology, hypothesis rejection controls, and evidence-required reporting standards.

VectorGuard Labs delivers truth, not theatrics so you can walk into a formal audit confident that every finding is real, defensible, and validated.

FAQ

VectorGuard Labs provides an adversarial pre-audit assessment. We behave like attackers: we threat model, define invariants, fuzz, simulate, and (where possible) build exploit PoCs on forks. Formal audits are typically compliance and assurance artifacts that happen after you’ve hardened your code. Our job is to prepare you so audit firms find fewer issues and you have stronger evidence of security.

You'll receive a professional, adversarial security assessment focused on identifying real, exploitable risks in your protocol. Depending on the engagement scope, this includes structured attack-surface analysis, systematic testing using VectorGuard Labs’ methodology, clear findings with severity and impact explanations, and concrete remediation guidance. Where exploitation is realistically demonstrable, findings are supported with technical evidence to validate risk, helping your team remediate issues confidently and prepare for a formal audit without surprises.

VectorGuard Labs does preliminary security assessments on Solidity, Vyper, Rust, Cairo, and Move smart contracts across EVM chains and other ecosystems. The 15-phase framework adapts to each stack using the strongest available validation method on that chain (forks, localnets, test-validators, or execution traces).

We need your smart contract source code. That's it. No test files, no documentation, etc. We can work with private GitHub repos or secure file transfers. Like attackers, we won't read your documentation, tokenomics, or whitepapers.

We sign comprehensive NDAs before accessing any code and maintain strict confidentiality protocols. Your code is stored in encrypted, access-controlled environments and is deleted after engagement completion. Our role is to help you harden and protect your codebase, not to reuse or disclose your intellectual property.

The Quick Pass Assessments are normally completed within 1-2 weeks depending on protocol complexity, with detailed reports highlighting vulnerabilities, attack scenarios, and recommended fixes. The 15-Phase Extensive Assessment normally take 4-6 weeks. Larger or highly complex systems may require additional time for deeper simulation and exploit development.

No. The VectorGuard attack vectors represent a comprehensive threat model, not a checklist applied blindly. Your protocol is first analyzed to determine which vectors are actually relevant to its architecture, assets, and integrations. We then apply the applicable vectors rigorously and go deep on the areas that present the highest real-world exploit risk, rather than performing superficial checks where no realistic attack surface exists.

No security assessment can guarantee that all vulnerabilities are eliminated. What we provide is structured, adversarial, evidence-backed testing using the VectorGuard framework. Our goal is to dramatically reduce your risk, uncover realistic attack paths, and prepare you for formal audits—not to promise absolute immunity from future bugs or exploits.

No, VectorGuard Labs strongly recommend proceeding to a formal third-party audit before mainnet deployment. Our pre-audit assessment is designed to prepare you for a successful formal audit by identifying and fixing vulnerabilities early. The formal audit provides the final compliance certification needed for mainnet launch, and you should treat our work as a high-value, adversarial pre-stage not a replacement.

The Quick Pass Assessment is ideal if you want a fast, adversarial check to uncover real, high-risk vulnerabilities before launch, fundraising, or committing to a full audit. It’s a focused, time-boxed engagement designed to surface only issues that matter. The 15-Phase Extensive Assessment is designed for teams preparing for production deployment, significant TVL, or a Tier-1 audit. It delivers a comprehensive, exploit-driven security assessment across architecture, execution logic, and economic design to harden your protocol against sophisticated attacks. If you’re unsure, many teams start with the Quick Pass and upgrade once deeper analysis is warranted.

VectorGuard Labs is crypto-native and accepts USDC on the BASE blockchain (RECOMMENDED)—no traditional banking delays or conversion fees.
