Constructor Security

Constructor security focuses on the risks associated with the initial deployment and configuration of a smart contract. In traditional programming, constructors are used to initialize state, but in upgradeable proxy patterns, they cannot be used because the proxy is the one holding the state.

This requires the use of separate initialization functions. If these functions are not handled with care, they can be vulnerable to frontrunning or re-initialization attacks.

Secure deployment practices involve using factory contracts, proper access control on initializers, and thorough testing of the deployment script. Ensuring that the contract starts in a secure, well-defined state is essential for long-term protocol safety.

It prevents the exploitation of the initial, often fragile, setup phase.
