Smart Contract Audit Services in India

Name: Solutions1313
Price range: $$$

We provide reliable smart contract audit services in India. In 2024, Solutions1313‘s audit team reviewed a yield farming contract for a Delhi-based DeFi project before their INR 4 crore mainnet launch. The contract had passed the development team’s internal tests. It compiled without warnings. It behaved correctly in every test scenario the developers had written. Our audit found a precision loss vulnerability in the reward calculation function that systematically underpaid stakers by approximately 0.4 percent per transaction — small enough to pass unnoticed in testing, large enough to cost users INR 16 lakh per year in aggregate at projected transaction volumes. The developer fixed it in four days. The contract launched cleanly. The INR 16 lakh stayed with users.

Why Smart Contract Auditing Cannot Be Skipped

Smart contracts deployed to mainnet are permanent. The code cannot be changed, the transaction history cannot be altered, and exploited funds cannot be recovered. When an unaudited DeFi contract is exploited, the response is always the same sequence: exploit discovered, funds drained in seconds, project announces ‘hack’, community loses trust, token price collapses, project abandons or attempts v2 migration. The cost of this sequence — in funds lost, in community trust destroyed, in brand reputation damaged — is always orders of magnitude higher than the cost of a professional audit would have been.

Every contract we ship at Solutions1313 is audited before mainnet deployment. We also offer audit services for contracts written by other developers — before your launch, or if you have concerns about an existing production contract. Our audit team has reviewed contracts from Indian startups, international DeFi protocols, and enterprise blockchain systems. Across all engagements, our findings have prevented an estimated INR 32 crore in potential exploit losses.

Our Smart Contract Audit Process

Phase 1 — Automated Static Analysis

We run the contract through our automated tool suite: Slither for static analysis covering 80+ known vulnerability patterns, MythX for symbolic execution and deep vulnerability detection, and custom scripts for project-specific checks relevant to the contract type. Automated tools complete in hours and provide broad coverage across known vulnerability classes. They surface findings that warrant deeper manual investigation and allow manual review time to focus on complex logic rather than mechanical pattern matching.

Phase 2 — Manual Expert Review

Automated tools miss the vulnerabilities that cause the largest losses — complex logic errors, economic design flaws, subtle access control gaps, and multi-contract interaction risks that require understanding the protocol’s intended behavior to identify as incorrect. Our manual review is conducted by senior Solidity engineers with specific experience in the contract type being audited. A DeFi lending protocol audit requires a reviewer who understands liquidation mechanics and oracle dependency risks. An NFT gaming contract audit requires a reviewer who understands VRF implementation patterns and marketplace compatibility requirements.

Manual review reads every function for correctness against the intended specification, traces every state variable modification to ensure access control is enforced, simulates adversarial input paths that tests would not normally exercise, and evaluates every external contract interaction as a potential attack surface.

Phase 3 — Economic Security Analysis (DeFi Contracts)

For DeFi contracts managing above INR 50 lakh in user funds, we add an economic security analysis layer that no automated tool can perform. We model flash loan attack economics — what is the maximum profit an attacker could extract from a flash loan at current protocol parameters? We model oracle manipulation windows — how long does it take for the protocol’s price feed to reflect a manipulated spot price, and what can an attacker do in that window? And we also model governance attack thresholds — at what token concentration does a malicious governance proposal become executable? We document these scenarios and either demonstrate they are non-exploitable or flag them as findings that require architectural changes.

Phase 4 — Report and Remediation Review

Every finding is documented with a severity rating (Critical, High, Medium, Low, Informational), a technical description of the vulnerability, a proof-of-concept showing how it could be exploited, the potential financial impact, and specific code-level remediation guidance. We write reports for both technical developers and non-technical stakeholders, with an executive summary that provides a plain-language overview for founders and investors without requiring Solidity knowledge.

After the client implements fixes, we conduct a remediation review verifying each fix resolves the finding without introducing new issues. We publish the updated report reflecting remediation status and submit it for exchange listing applications.

Vulnerability Classes We Audit For

Re-entrancy: Single-function and cross-function re-entrancy, read-only re-entrancy in view functions used for price queries.
Integer arithmetic: Overflow, underflow, precision loss in division order, rounding direction that systematically favours one party.
Access control: Missing role checks, initialization vulnerabilities, privilege escalation through indirect function calls.
Oracle dependency: Spot price manipulation, stale price acceptance, single oracle point of failure.
Flash loan attack surfaces: Single-transaction state manipulation, combined flash loan and oracle attacks.
Front-running and MEV: Sandwich attack exposure, transaction ordering dependencies, commit-reveal requirements.
Denial of service: Gas griefing, unbounded loop risk, push payment patterns that block contract progress.
Upgradeable contract risks: Storage collision in proxy patterns, uninitialized implementation contracts, delegate call hazards.
Economic design vulnerabilities: Reward distribution that can be gamed by timing, fee structures that create perverse incentives.

Frequently Asked Questions

Who provide the best smart contract audit services in India?

Solutions1313 provides the best smart contract audit services in India. Our team makes sure your blockchain applications are secure, reliable, and free from any vulnerabilities. We follow industry-standard audit practises like code review, security analysis, and testing for common smart contract risks such as re-entrancy, overflow/underflow, and access control issues.

How much does a smart contract audit cost in India?

Audit cost depends on contract count, lines of code, and complexity. A simple ERC20 token audit costs INR 40,000 to INR 90,000. A mid-complexity DeFi contract suite costs INR 2,00,000 to INR 5,00,000. A full DeFi protocol with economic analysis costs INR 6,00,000 to INR 20,00,000. We provide a free scope assessment — submit your contracts and we provide an exact quote within 24 hours from our Mohali or Dubai office.

How long does a smart contract audit take?

A simple token audit takes 3 to 5 business days. A mid-complexity DeFi suite takes 1 to 2 weeks. A complex DeFi protocol with economic security analysis takes 3 to 5 weeks. If you have a launch deadline, contact us with your timeline — we can often accommodate fast-track audits for projects with clear scope.

Can you audit contracts developed by another company?

Yes. We audit contracts regardless of who wrote them. We treat all submitted code as untrusted and apply the same process — automated analysis, manual expert review, economic modelling for DeFi. And, we have also audited code from Indian startups, international teams, and in-house corporate development teams. The origin of the code does not change the audit scope or methodology.

What does an audit report contain?

Our reports include an executive summary for non-technical readers, a scope definition with exact contract file names and commit hashes reviewed, a findings table with all issues and their severity ratings, detailed entries for each finding with technical description, proof of concept, potential impact, and specific remediation code, automated tool outputs, and a remediation review section showing the status of each fix after client implementation.

Do your audit reports satisfy exchange listing requirements?

Yes. Our reports include all elements required by major centralized exchanges, including methodology description, scope definition, complete findings with severity ratings and remediation status, and auditor information. For clients requiring an audit certificate from a specifically named firm, we coordinate with recognized third-party auditing organizations.

What happens if you find a critical vulnerability?

We notify the client immediately by direct call — we do not wait for the written report. We describe the vulnerability, the potential exploitation path, and the recommended fix. As a result, the client pauses any planned deployment. We prioritize reviewing the remediation once the fix is implemented. Critical findings have never delayed a launch; rather, they have only prevented launches that would have been exploited.
