Smart Contract Security Audit

Smart contract security audit — before real money is at risk.

We audit Solidity and Rust smart contracts for funded startups deploying real value on-chain. Reentrancy, access control, front-running, flash loan vulnerabilities, and more — reviewed by engineers who have shipped and fixed production contracts.

Audit Coverage

What our smart contract security audit covers.

Our smart contract audit service reviews every critical vulnerability class — from classic reentrancy to complex DeFi-specific economic exploits. You receive a written report with severity ratings and actionable remediation guidance.

🔄

Reentrancy Attacks

Checks-effects-interactions violations, cross-function reentrancy, and read-only reentrancy that allows state manipulation via flash loans and external calls.

🔐

Access Control Flaws

Missing or misconfigured role-based access, unprotected initialiser functions, privilege escalation paths, and admin key centralisation risks.

📊

Arithmetic Vulnerabilities

Integer overflow and underflow in pre-0.8 contracts, precision loss in fixed-point math, rounding errors in reward calculations, and unsafe casting.

Flash Loan Exploits

Price oracle manipulation via flash loans, same-block attack vectors, and liquidity manipulation vulnerabilities in DeFi protocols.

🏃

Front-Running & MEV

Transaction ordering dependencies, sandwich attack exposure, commit-reveal scheme analysis, and deadline/slippage configuration review.

🔗

External Call Risks

Unchecked return values, delegatecall misuse, low-level call vulnerabilities, and unsafe interactions with external contracts and tokens.

🛠️

Upgrade & Proxy Risks

Storage collision in proxy patterns, initialisation gaps in upgradeable contracts, and function selector clashing in transparent and UUPS proxies.

📜

Business Logic Errors

Off-by-one errors, incorrect state transitions, reward calculation bugs, and tokenomics vulnerabilities that create unintended economic exploits.

Audit Process

How our smart contract audit service works.

01

Scope intake

You share your contracts, deployment context, and any known risk areas. We review the codebase size, complexity, and external dependencies to give you an accurate timeline and fixed-price quote.

02

Manual & automated review

Our engineers conduct a line-by-line manual review alongside automated static analysis (Slither, Mythril). Automated tools find patterns; manual review finds the logic errors that matter.

03

Draft report & developer Q&A

We deliver a draft report with every finding classified by severity (Critical, High, Medium, Low, Informational). We walk through findings with your dev team and answer questions before finalising.

04

Remediation review & final report

After your team applies fixes, we re-review all Critical and High findings and confirm remediation. The final report is a document your investors, auditors, and community can read.

FAQ

Questions about smart contract audits.

A smart contract security audit is a systematic review of your Solidity or Rust contract code by security engineers looking for vulnerabilities before deployment. The audit covers logic errors, economic exploits, access control flaws, and known vulnerability patterns. You receive a written report with severity-classified findings and remediation guidance.
If your contracts handle real user funds or govern protocol parameters, yes — always. The cost of an audit is a fraction of what a single exploit costs: financially, reputationally, and legally. Audits won't catch everything, but they significantly reduce the attack surface and signal to your community that you take security seriously.
An internal review (like what we include in every development engagement) is conducted by the team that wrote the code — valuable, but limited by familiarity bias. An independent audit is conducted by engineers with no prior context, fresh eyes, and no pressure to ship. For contracts handling significant value, both are recommended.
Yes. We audit Solana programs written in Rust, covering Anchor framework-specific vulnerabilities, account validation issues, PDA misuse, and signer verification failures — in addition to standard logic and arithmetic checks.
A standard ERC-20 or staking contract audit takes 3–5 business days. A complex DeFi protocol with multiple interacting contracts is typically 10–15 business days. We assess timeline accurately after reviewing your codebase in the scope intake.
The report includes: executive summary, scope and methodology, all findings with severity classification (Critical / High / Medium / Low / Informational), proof-of-concept for critical issues, specific remediation recommendations, and a final remediation confirmation section after your fixes are reviewed.

Don’t deploy until your contracts have been audited.

Share your contract code and we’ll scope the audit, give you a fixed price, and start within 5 business days. No lock-in, no retainers.
