The GnosisSafeProxy contract serves as a proxy that delegates calls to a designated singleton contract, allowing for flexible and upgradable contract interactions. It is initialized with the address of the singleton contract, ensuring that all incoming transactions are forwarded appropriately. The contract utilizes a fallback function to handle these delegations, maintaining the integrity of the original call data and return values.
Contract Initialization:
constructor: This function initializes the proxy by setting the address of the singleton contract. It validates that the provided address is not a zero address, reverting if it is invalid. No events are emitted during this process, and no external interfaces are called.Transaction Delegation:
fallback: This payable fallback function forwards all incoming transactions to the singleton contract. It checks if the call is for the masterCopy() function and returns the address of the master copy if so. Otherwise, it delegates the call to the master copy using delegatecall, handling the return data and reverting if the call fails. No events are emitted, and no external interfaces are called directly.
