A six-stage pipeline combining AI automation with human expertise for maximum coverage and accuracy.
Our AI tools scan the entire codebase for known vulnerability patterns, control flow issues, and data dependency risks.
Machine learning models identify suspicious patterns, anomalous logic, and potential attack vectors across the contract.
Senior auditors deep-dive into business logic, edge cases, and complex interactions that AI flags for human judgment.
All findings are categorized by severity (Critical, High, Medium, Low, Informational) with CVSS scoring.
Detailed remediation guidance with code examples, best practices, and gas optimization suggestions for each finding.
Free re-audit of fixed code within 30 days to verify all critical and high-severity issues are properly resolved.
Multi-chain security expertise with deep specialization in Solana and EVM ecosystems.
Deep expertise in Solana program auditing. We understand account validation, PDA security, CPI risks, and Solana-specific attack vectors.
Comprehensive EVM auditing across Ethereum, Base, Polygon, Arbitrum, and other EVM-compatible chains.
Specialized in cross-chain bridge audits and interoperability protocol security, where vulnerabilities can be catastrophic.
Comprehensive coverage across all major smart contract vulnerability classes.
Cross-function and cross-contract reentrancy attack detection
Arithmetic overflow/underflow in token calculations and balances
Missing or improper authorization checks on privileged functions
Vulnerabilities exploitable through flash loan price manipulation
Oracle dependency risks and TWAP manipulation vectors
Transaction ordering dependencies and MEV extraction risks
Business logic flaws, incorrect state transitions, and edge cases
Inefficient storage patterns, redundant operations, and gas savings
Every audit includes a comprehensive report with actionable findings and a public audit certificate.
High-level overview of audit scope, methodology, risk assessment, and key findings for stakeholders and investors.
Comprehensive breakdown of every issue found, categorized as Critical, High, Medium, Low, or Informational with full technical analysis.
Working PoC exploits for critical and high-severity findings demonstrating real-world attack scenarios.
Specific code-level remediation guidance with before/after examples and best practice references.
Detailed gas usage analysis with optimization recommendations to reduce deployment and transaction costs.
Verified audit certificate for your project website, building trust with users, investors, and the community.
Our AI tools scan for known patterns before human review, catching 40% more issues than manual-only audits.
Deep expertise in Solana/Rust/Anchor — not just EVM. We understand Solana-specific security patterns and attack vectors.
Unlike pure audit firms, we can fix what we find. Combined audit and development capabilities accelerate your timeline.
Preliminary findings report within the first week. Full audits completed 30-50% faster with our AI-augmented pipeline.
Clear, upfront pricing with no surprise fees. Free initial assessment to scope your audit accurately.
Post-audit security monitoring options to detect threats in real-time and protect your protocol continuously.
A smart contract audit is a comprehensive security review of blockchain smart contract code to identify vulnerabilities, logic errors, and optimization opportunities before deployment. Builderz combines AI-augmented analysis with expert manual review to deliver thorough audits for Solana (Rust/Anchor), EVM (Solidity), and Move-based contracts.
Smart contract vulnerabilities have caused billions in losses. An audit protects your users' funds, builds trust with investors, meets regulatory requirements, and prevents costly exploits. Builderz audits have protected over $500M in total value locked across DeFi, NFT, and tokenization projects. A $15K audit can prevent a $15M exploit.
Smart contract audit pricing: Basic audits for simple contracts ($10,000-$25,000), comprehensive audits for DeFi protocols ($25,000-$75,000), enterprise-grade audits with formal verification ($75,000-$200,000). Pricing depends on code complexity, lines of code, and urgency. Builderz offers free initial assessments to scope your audit accurately.
Builderz audits smart contracts across: Solana (Rust, Anchor framework), Ethereum and EVM chains (Solidity, Vyper), and emerging chains. Our deep Solana expertise is a key differentiator — we've audited 20+ Solana programs including DeFi protocols, NFT marketplaces, and token programs. We also audit cross-chain bridges and interoperability protocols.
Builderz uses AI tools to enhance (not replace) human auditors. AI performs initial pattern scanning across the entire codebase, identifies known vulnerability signatures, analyzes control flow and data dependencies, and generates test cases. Human experts then deep-dive into flagged areas, assess business logic, and verify AI findings. This hybrid approach catches 40% more issues than manual-only audits.
Audit timelines: Simple contracts (under 500 LOC) take 1-2 weeks, moderate complexity (500-2000 LOC) 2-4 weeks, complex DeFi protocols (2000+ LOC) 4-8 weeks. Builderz offers expedited audits (50% faster) for time-sensitive launches. We provide a preliminary findings report within the first week for critical issues.
Builderz audit reports include: executive summary with risk assessment, detailed findings categorized by severity (Critical, High, Medium, Low, Informational), proof-of-concept exploits for critical issues, specific code fix recommendations, gas optimization suggestions, best practice compliance check, and a public-facing audit certificate for your project's website.
Yes. All Builderz audits include one free re-audit of fixed code within 30 days. We verify that all critical and high-severity findings are properly resolved, check that fixes don't introduce new vulnerabilities, and update the audit report. Additional re-audits are available at 30% of the original audit cost.
