Smart Contract Code Review & Auditing

CryptoLions provides professional smart contract code review and security auditing services for projects building on Antelope (EOSIO) blockchains, including EOS/Vaulta, WAX, Ultra, and Telos.

Service Overview

Drawing on years of hands-on experience building and maintaining production-grade smart contracts in the Antelope ecosystem, CryptoLions reviewers apply deep protocol knowledge to identify vulnerabilities, logic errors, and anti-patterns before mainnet deployment. Their open-source contributions — including the widely adopted SimpleAssets NFT standard — and long-standing role as a block producer across multiple Antelope chains provide a strong foundation for practical, ecosystem-aware security reviews.

What's Included

• Smart Contract Security Review — C++ and EOSIO smart contract logic, access control, and vulnerability assessment
• Security Analysis — Identification of reentrancy risks, permission escalation, inline action abuse, and other Antelope-specific attack vectors
• Frontend & Backend Review — JavaScript, TypeScript, and Node.js dApp code quality and security assessment
• Architecture Review — Evaluation of system design, integration points, and on-chain/off-chain boundaries
• Best Practices Assessment — Code quality, upgradeability patterns, and deployment readiness checks

Why Choose CryptoLions

As one of the longest-standing Antelope ecosystem contributors since the EOS genesis in 2018, CryptoLions bring unmatched practical knowledge of the blockchain's runtime behaviour, consensus mechanics, and common pitfalls. Teams deploying to EOS, WAX, Ultra, or Telos benefit from reviewers who have shipped and maintained real production contracts in the same environment.
