Minimize security risks in your Optimism Smart Contracts

Reentrancy Attacks
Reentrancy Attacks
We thoroughly review the contract’s control flow to identify any potential reentrancy vulnerabilities. We also ensure that external calls are made after state changes to prevent reentrant calls.
Unchecked External Calls
Unchecked External Calls
We review all external calls made by the contract. We validate return values and handle exceptions properly, using try/catch blocks.
Timestamp Dependence
Timestamp Dependence
We assess whether the contract relies on timestamps for critical logic. We check timestamp-based conditions, especially for randomness or time-sensitive actions.
Uninitialized Storage Variables
Uninitialized Storage Variables
We verify that all storage variables are properly initialized. Uninitialized variables can lead to unexpected behaviour, so we examine this closely.
Front-Running Attacks
Front-Running Attacks
We consider potential front-running scenarios. Using features like block.timestamp or block.number, we mitigate front-running risks.
Unchecked Send Operations
Unchecked Send Operations
We evaluate how Ether is sent within the contract.
