Web3
Security

Rigorous deep-dive security audits of smart contracts, DeFi protocols, and blockchain infrastructure. We expose critical vulnerabilities before your code goes on-chain and financial losses become irreversible.

What We Audit in Your Web3 Project

Comprehensive security coverage for smart contracts, DeFi protocols, and the broader blockchain infrastructure layer.

Smart Contract Audit

Manual and automated review for reentrancy, integer overflow, access control, and logic flaws in Solidity, Vyper, and Rust contracts.

DeFi Protocol Security

Flash loan attack simulation, oracle manipulation testing, and tokenomics risk analysis for lending, DEX, and yield protocols.

Pre-Deployment Testing

Testnet fuzzing, gas optimisation review, and access control checks before mainnet launch.

Audit Report and Certification

Public-ready audit report with severity-rated findings, proof-of-concept exploits, and remediation verification.

NFT and Token Security

Review NFT minting contracts, royalty logic, marketplace integrations, and ERC-20/721/1155 implementations for security flaws.

Wallet and Key Management

Assess multi-sig wallet configurations, private key storage, signing workflows, and admin key exposure risks.

Flash Loan Attack Simulation

Test protocol resilience against flash loan-enabled price manipulation, arbitrage exploitation, and cascade liquidation scenarios.

Oracle Manipulation

Assess price oracle integrations for manipulation vectors, stale data feeds, and single-source dependency risks.

Governance Attack

Evaluate DAO governance mechanisms for vote buying, flash governance, and proposal manipulation vulnerabilities.

NFT Minting Exploits

Test minting functions for reentrancy, over-minting, metadata manipulation, and royalty bypass vulnerabilities.

Cross-Chain Bridge Security

Assess bridge contracts, relayers, and wrapped token implementations for fund theft and double-spend risks.

Liquidity Pool Risks

Evaluate AMM pool contracts for impermanent loss manipulation, rug-pull vectors, and fee calculation exploits.

Node and RPC Security

Assess blockchain node configurations, RPC endpoint exposure, and consensus mechanism vulnerabilities.

Layer 2 and Sidechain

Review rollup contracts, bridge mechanisms, and sequencer configurations for censorship and fund-locking risks.

Staking and Validation

Evaluate staking contract security, validator key management, and slashing condition implementations.

API and Indexer Security

Test subgraph configurations, blockchain API endpoints, and data indexing services for manipulation and exposure.

DevOps and Deployment

Audit deployment scripts, upgradeable contract patterns, and proxy configurations for storage collision and init flaws.

Compliance and KYC

Review on-chain compliance mechanisms, KYC integration patterns, and regulatory reporting capabilities.

How We Run a Web3 Security Audit

A structured six-phase process combining automated tooling with expert manual review, from initial scoping through verified remediation.

Phase 01
Scoping

Define the contract scope, interfaces, and risk profile of the protocol. Identify high-value targets and critical financial logic.

01
02
Phase 02
Static Analysis

Automated tooling including Slither, Mythril, and Echidna to surface known vulnerability patterns across all in-scope contracts.

Phase 03
Manual Review

Line-by-line manual code review by blockchain security engineers to find logic flaws, business logic errors, and edge cases that automated tools miss.

03
04
Phase 04
PoC Exploitation

Develop proof-of-concept exploits for critical findings to demonstrate real financial impact in a controlled forked environment.

Phase 05
Reporting

Severity-rated findings report with proof-of-concept code, attack scenarios, and step-by-step remediation guidance for each vulnerability.

05
06
Phase 06
Remediation Verify

Re-audit after fixes to confirm all findings are resolved before final sign-off and public audit report issuance.

Built for Projects With Real On-Chain Value

DeFi Protocols and DAOs

Decentralised finance platforms, lending protocols, DEXs, and DAO-governed treasuries where a single vulnerability can result in irreversible financial loss.

NFT Platforms and Marketplaces

NFT minting platforms, marketplaces, and creator tools where contract bugs can lead to rug-pulls, royalty bypass, or stolen assets.

Blockchain Startups and Enterprises

Web3 companies launching token-gated products, cross-chain bridges, or enterprise blockchain solutions requiring independent security validation.

Questions We Get Asked Often

Web3 security assessment is a comprehensive audit of smart contracts, DeFi protocols, and blockchain infrastructure. It combines automated static analysis with manual expert review to identify reentrancy, access control flaws, logic errors, and financial vulnerabilities before code is deployed on-chain.

Smart contract vulnerabilities are immutable once deployed and often hold millions in locked value. A single reentrancy bug or access control flaw can lead to irreversible financial loss. Audits identify these issues before deployment, when they can still be fixed.

Yes. We perform specialised DeFi security assessments including flash loan attack simulation, oracle manipulation testing, governance attack analysis, and liquidity pool risk evaluation. All testing is conducted on forked mainnet environments.

We combine automated static analysis (Slither, Mythril, Echidna, Foundry) with manual expert code review. Automated tools catch known patterns; manual review catches business logic flaws, edge cases, and protocol-specific vulnerabilities that tools miss.

You receive a severity-rated findings report with proof-of-concept exploits and remediation steps. After your team applies fixes, we re-audit to confirm all findings are resolved before issuing a final sign-off and public audit report.
