Solidity Auditor-AI-powered Solidity code audits

Example

Identifying reentrancy vulnerabilities in a decentralized finance (DeFi) smart contract.

Scenario

A developer has created a DeFi protocol that involves borrowing and lending operations. Before deployment, they use Solidity Auditor to scan the contract for known vulnerabilities. The Auditor detects a potential reentrancy attack vector, where a malicious user could repeatedly call a withdrawal function before the contract updates the user's balance, leading to unintended depletion of the contract’s funds. The Auditor flags this issue and provides suggestions on how to mitigate it by using mutexes or proper function ordering.

Example

Reducing gas consumption in a smart contract that manages a large array of user balances.

Scenario

An NFT marketplace contract frequently reads from and writes to a large array containing user data. By using Solidity Auditor, the developer identifies inefficient code patterns that consume excess gas, such as unnecessary storage writes or expensive loops. The Auditor suggests replacing certain operations with more efficient ones, like using 'mapping' instead of 'array' for storage or optimizing loop constructs. The developer applies these changes, significantly reducing the gas fees for their users, which in turn makes their platform more attractive.

Example

Ensuring compliance with Solidity version updates and industry standards.

Scenario

A company plans to release a token sale contract. To ensure that their code complies with the latest Solidity version and aligns with the Ethereum community's best practices, they run it through Solidity Auditor. The Auditor checks for deprecated functions, identifies syntax or logic that might not be compatible with the newest Solidity version, and flags areas where industry best practices are not followed. This process helps the company avoid potential security risks or functionality problems that could arise from using outdated or non-standard code.
