Smart Contract
Audit

Rigorous deep-dive security audits of smart contracts in Solidity, Vyper, and Rust. We expose reentrancy, access control flaws, and logic errors before your code goes on-chain and financial losses become irreversible.

Testing Areas

What We Audit in Your Smart Contract

Comprehensive security coverage for smart contract code, DeFi protocol logic, and the infrastructure your contracts depend on.

Solidity Contract Audit

Manual and automated review for reentrancy, integer overflow, access control, and logic flaws in Solidity contracts across EVM-compatible chains.

Vyper and Rust Contracts

Security review of Vyper contracts on EVM chains and Rust-based programs on Solana and Near, covering language-specific pitfalls and edge cases.

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.

Upgradeable Contract Patterns

Review proxy patterns, storage collision risks, initialisation logic, and admin privilege escalation in upgradeable contract architectures.

Access Control and Privileges

Assess role-based permissions, owner-only functions, multi-sig configurations, and admin key exposure risks across all contract interfaces.

DeFi Protocol Audits

Comprehensive review of lending, DEX, and yield protocol contracts for flash loan vulnerabilities, oracle manipulation, and tokenomics flaws.

Oracle and Price Feed Security

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

Token and Governance Audits

Review ERC-20/721/1155 implementations, DAO governance mechanisms, vote buying risks, and proposal manipulation vulnerabilities.

NFT Contract Security

Test minting functions for reentrancy, over-minting, metadata manipulation, royalty bypass, and marketplace integration flaws.

Cross-Chain Bridge Contracts

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

Liquidity Pool and Staking

Evaluate AMM pool contracts, staking logic, reward distribution, and fee calculation for exploitation vectors.

Node and RPC Security

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

Layer 2 Rollup Contracts

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.

Deployment and Upgrade Safety

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

Gas Optimisation Review

Identify gas-inefficient patterns and assess whether optimisations introduce security trade-offs or unexpected behaviour.

Formal Verification

Mathematical proving of critical invariant properties for high-value contracts using formal verification tools and invariant testing.

Methodology

How We Run a Smart Contract 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. Identify high-value targets, critical financial logic, and upgradeable patterns.

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.

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.

Phase 06

Remediation Verify

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

Who It's For

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 smart contract vulnerability can result in irreversible financial loss.

NFT Platforms and Token Issuers

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

Web3 Startups and Enterprises

Companies launching smart contract products, cross-chain bridges, or enterprise blockchain solutions requiring independent security validation before deployment.

FAQ

Questions We Get Asked Often

A smart contract audit is a comprehensive security review of your contract code combining automated static analysis with manual expert review. It identifies reentrancy, access control flaws, integer overflows, logic errors, and other vulnerabilities before code is deployed on-chain and losses become irreversible.

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.

We audit Solidity, Vyper, and Rust smart contracts across EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, BSC), Solana, and Near. We also review upgradeable proxy patterns, cross-chain bridges, and layer-2 rollup contracts.

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.
