◆ FAQ

Frequently Asked Questions

What is a smart contract audit?+

A smart contract audit is a comprehensive security review of blockchain code to identify bugs, vulnerabilities, and logic errors before deployment. Auditors manually review the code line-by-line and use automated tools to detect issues like reentrancy attacks, integer overflow, unauthorized access, and gas inefficiencies. An audit report classifies each finding by severity and provides remediation guidance.

Why does my project need a smart contract audit?+

Without an audit, a single exploit can drain your treasury, rug your community, and permanently destroy your project's reputation. High-profile hacks like the Ronin Bridge ($625M), Poly Network ($611M), and countless DeFi protocols were caused by unaudited or poorly audited smart contracts. Investors, exchanges, and community members increasingly require audit reports before participating.

Which contracts do you audit?+

ERC-20 token contracts, ERC-721 and ERC-1155 NFT contracts, staking and yield farming contracts, governance and DAO contracts, liquidity pool and AMM contracts, custom DeFi protocols, vesting and lockup contracts, and multisig wallet implementations.

How much does a smart contract audit cost?+

Smart contract auditing starts at Rs.35,000 for standard ERC-20 or NFT contracts and scales based on code complexity, number of contracts, and lines of code. DeFi protocols with complex logic are quoted on a case-by-case basis. Message on Telegram for a free scope assessment and custom quote.

How long does the audit take?+

Standard token contract audits take 3 to 5 business days. Complex DeFi protocols or multi-contract systems take 7 to 14 days depending on scope. Rush audits are available. Timeline starts after code submission and scope confirmation.

What is the difference between a manual audit and automated scanning?+

Automated tools scan for known vulnerability patterns quickly but miss complex logic errors and context-dependent bugs. Manual review by an experienced auditor catches issues that tools cannot — including business logic flaws, economic attack vectors, and protocol-specific vulnerabilities. The best audits combine both approaches, which is exactly what this service provides.
