Summary

The contract cannot accept ETH either through direct transfers or via the script, as it lacks a receive() or fallback() function.

This could lead to potential loss of user funds, as users may be unable to claim their prize if the contract does not have sufficient ether available.

Vulnerability Details

The contract has no way to receive ether.

Impact

The vulnerability may result in users' funds being trapped. If the contract lacks sufficient ether and the transfer fails, users will be unable to claim their prize and will also lose the 1 ether they initially deposited.
