The EVM’s specific execution environment introduces risks tied to how opcodes are executed and state is managed. At Audit Labs, we conduct detailed opcode-level analysis to ensure that your Solidity contracts are optimized for both gas efficiency and security. We look for potential issues such as excessive storage writes, unnecessary state reads, and the misuse of expensive opcodes that could lead to unexpected behavior or vulnerabilities. We ensure your contract interacts securely with the EVM’s low-level bytecode, reducing the attack surface and optimizing performance without compromising security.

The EVM’s account-based model can be prone to vulnerabilities such as unauthorized state changes and double-spending. Audit Labs reviews how your contract manages balances, ensuring the accuracy of funds transferred between accounts while securing state transitions. We identify flaws in transaction handling, such as inconsistent state or vulnerabilities that could be exploited for unauthorized balance manipulation. Our audits ensure your contract operates securely within Ethereum’s account model, maintaining the integrity of user funds and contract state.

While upgradable smart contracts are essential for long-term project sustainability, improper implementation of proxy patterns can introduce significant security risks, such as unauthorized contract upgrades or vulnerabilities in upgrade logic. Audit Labs specializes in auditing upgradeable contract patterns, focusing on ensuring that proxy contracts are secure, transparent, and resistant to manipulation. We evaluate the security of upgrade mechanisms, ensuring that only authorized parties can execute upgrades and that no unexpected behaviors or vulnerabilities are introduced during contract evolution.

Within the Ethereum Virtual Machine (EVM), inefficiencies in gas usage can lead to significant security concerns, including denial-of-service (DoS) vulnerabilities due to high transaction costs. Audit Labs focuses on analyzing contract operations at the opcode level to identify gas-heavy operations that could be exploited by attackers to drain resources. We also ensure that gas consumption is tightly controlled through optimization techniques such as reducing redundant state modifications, minimizing storage access, and ensuring optimal transaction execution flows.
