xAudits

xAudits is a blockchain security firm specialising in smart contract audits for Web3 projects, founded around 2022. Built by a team that describes itself as "from builders for builders," xAudits combines hands-on development experience with deep security expertise to deliver thorough code reviews across both EVM and non-EVM blockchain ecosystems. The firm holds a 4.9 Trustpilot rating and has audited notable projects including Itheum, OneDex, VestaX Finance, Sense4FIT, and SuperRareBears.

Core Services

xAudits' primary offering is its Smart Contract Audit service, which covers Solidity and Rust smart contracts across a wide range of supported chains including MultiversX, Ethereum, Solana, BNB Smart Chain, Polygon, Avalanche, Near, Algorand, Tezos, Casper, Cosmos, Polkadot, Fantom, and EOS. Each audit involves at minimum two deep-dive code reviews — an initial review and a follow-up review after the client's team has addressed findings.

The audit process spans seven structured phases: source code intake, initial manual and automated analysis, stress testing, categorised issue detection, remediation recommendations, updated code review, and final report publication. Reported issues are classified by severity from Critical to Informational, and all completed audits are publicly listed in the client's dedicated project page on the xAudits platform.

The firm covers a broad variety of smart contract types, including DeFi protocols (lending, liquid staking, staking, farming, DEX, order book), tokenisation (NFT, NFT marketplace, vesting, distribution), infrastructure (launchpad, crowdfunding, multisig, attestation, lottery), and custom use cases. xAudits also offers advisory and consulting via its Smart Contract Audit Development Services page, helping teams understand best practices, improve code quality, and achieve gas efficiency.

• Builder perspective: Team members bring backgrounds in blockchain development, product management, and security research, enabling them to understand project requirements from both sides
• In-house delivery: All auditing is handled internally without outsourcing, keeping costs competitive while maintaining quality
• Attacker mindset: Security research methodology combines reverse engineering, cryptography, virtualisation, malware behaviour, and software exploit analysis
• Formal verification: Employs formal verification tools alongside manual review and automated testing
