Web3 Security & Smart-Contract Audits

Manual expertise augmented by AI to find more issues, faster then we help you fix, retest, and ship safely.

Deliverables

We provide comprehensive security services ranging from manual code review to automated AI analysis. Our goal is to ensure your protocol is production-ready with SWC/OWASP-mapped reports and actionable fixes.

Manual expertise augmented by AI to find more issues, faster then we help you fix, retest, and ship safely.

SWC/OWASP Report

+

Detailed security report mapped to industry standards with clear severity levels and exploit scenarios.

PR-level Fixes

+

Actionable recommendations provided directly in Pull Requests with diff-based retesting.

Threat Model

+

Definition of system invariants and properties to preserve against potential attack vectors.

CI/CD Setup

+

Integration of static analysis, fuzzing, tests, and gas/coverage gates into your development pipeline.

Monitoring & Ops

+

Implementation of incident runbooks, alerting rules, and on-chain analytics hooks.

Methods & Tooling

Static & Lint

+

Utilization of Slither and custom linters to catch common vulnerabilities early.

Property & Fuzz Testing

+

Advanced testing using Foundry/Forge, Echidna, and differential tests to find edge cases.

Economic Simulations

+

Scenario tests for fees, rewards, and liquidations, including oracle sanity checks (TWAP/median).

AI-Assisted Review

+

Pattern mining, heuristic ranking, and false-positive pruning with human-in-the-loop verification.

On-Chain Monitoring

+

Real-time alerts for invariant breaches, large transfers, or suspicious contract interactions.

What we cover

We audit and harden the entire Web3 stack, from contracts to operational security.

Smart Contracts

+

Solidity (EVM) and Rust (Substrate/Move-inspired) codebases.

System Security

+

Key management, access control, upgradeability patterns, pausability, and role design.

Economic & Oracle Risks

+

Price feeds, liquidation paths, reward/fee mathematics, and MEV attack vectors.

Operations

+

Incident response planning, upgrade procedures, and emergency actions.

Process (fast & production-oriented)

1

Scope & Baseline (1-2 days)

We analyze code/ABI, dependencies, privileges, and the upgrade plan to establish a baseline.

2

Analysis & Testing (1-2 weeks)

Manual review combined with AI-assisted triage, static/dynamic tests, fuzzing, and economic checks.

3

Findings & Fixes

Report walkthrough with developers, providing PR hints and secure patterns for remediation.

4

Retest & Ship

Verification of fixes, report update, and assistance with the pre-launch checklist.

5

Monitoring (Optional)

Setup of ongoing monitoring rules, alerts, and emergency response procedures.
