Frequently Asked Questions
How much does a MixBytes smart contract audit cost?
MixBytes offers customized pricing based on contract complexity, codebase size, and audit scope.

Contact MixBytes directly for a detailed quote tailored to your project's specific needs.
How long does a MixBytes audit typically take?
Audit timelines vary based on project complexity, but most MixBytes audits are completed within 1-2 weeks for standard projects. This includes initial review, vulnerability assessment, reporting, and re-audit after fixes. Complex protocols or larger codebases may require 2-4 weeks. Expedited audits are sometimes available for urgent launches.
What blockchain networks does MixBytes support?
MixBytes specializes in EVM-compatible chains including Ethereum, Binance Smart Chain, Polygon, Avalanche, Fantom, Arbitrum, and Optimism. They also have expertise in Substrate-based blockchains like Polkadot and Kusama, making them one of the few audit firms with genuine cross-chain auditing capabilities.
What makes MixBytes different from other smart contract audit firms?
MixBytes' zero-rekts track record since 2017 sets them apart—no project they've audited has experienced a security hack from vulnerabilities they should have caught. Their manual-first approach, multi-chain expertise, and comprehensive advisory services go beyond typical audits. Plus, their publicly available audit reports demonstrate transparency and build community trust.
Does MixBytes audit both new and existing smart contracts?
Yes! MixBytes audits new contracts before deployment (recommended for any mainnet launch) and can also audit existing contracts already on mainnet. For live projects, they'll analyze current code and often recommend upgrades to address newly discovered vulnerabilities or optimize gas efficiency.
What types of vulnerabilities does MixBytes look for?
MixBytes identifies common vulnerabilities like reentrancy attacks, integer overflow/underflow, access control issues, front-running susceptibility, and logic errors. They also check for gas optimization opportunities, centralization risks, and compliance with ERC standards. Their manual approach catches nuanced business logic flaws automated tools miss.
Will MixBytes fix the vulnerabilities they find, or just report them?
MixBytes provides detailed reports with specific code examples showing exactly where vulnerabilities exist and how to fix them. While they don't typically rewrite your code themselves, their recommendations are clear enough for your developers to implement fixes. They offer re-audits to verify all issues are properly resolved before publishing the final audit report.
Do I need an audit if I'm using audited code from OpenZeppelin or similar libraries?
Absolutely! Using audited libraries is a great start, but your custom implementation, integrations, and business logic still need thorough auditing. Most hacks occur in project-specific code rather than standard library components. MixBytes will review your entire codebase, including how you implement and combine different components.
Can MixBytes help with security after the audit is complete?
Yes, MixBytes offers ongoing technical advisory services to help maintain security best practices throughout your project's lifecycle. They can review upgrades, advise on security architecture changes, and help your team stay informed about new vulnerabilities and security trends relevant to your protocol.
How do I prepare for a MixBytes smart contract audit?
Before submitting to MixBytes, ensure your code is well-documented with clear explanations of intended functionality. Run basic static analysis tools like Slither or Mythril to catch obvious issues. Provide complete access to your repository, documentation, and any architectural diagrams. The more organized and thorough your submission, the smoother the audit process will be.
Does a MixBytes audit guarantee my smart contracts are 100% secure?
No audit can guarantee absolute security, as new vulnerabilities are constantly discovered and sophisticated attackers may find unexpected approaches. However, a MixBytes audit dramatically reduces your risk profile by catching known vulnerability types and logic errors. Their zero-rekts track record demonstrates the effectiveness of their thorough methodology.
Are MixBytes audit reports made public?
Yes, MixBytes publishes completed audit reports publicly on their website and shares them through their community channels. Public reports demonstrate transparency and help build trust with your users and investors. This public verification is valuable for fundraising, exchange listings, and community confidence.
