First Flight #1: PasswordStore

Summary

The PasswordStore smart contract doesn't currently include a self-destruct function. It's advisable to add such a function to allow the contract owner to destroy the contract when it's no longer needed. This can enhance the contract's security and is considered a best practice in smart contract development.

Vulnerability Details

The absence of a self-destruct function means that there's no way for the contract owner to terminate the contract voluntarily. While the contract appears to be relatively simple and benign, it's a good practice to include a mechanism to self-destruct the contract. This provides flexibility for contract owners in situations where the contract is no longer needed, reducing the risk of it being stuck on the blockchain indefinitely.

Impact

The impact of not having a self-destruct function is relatively low in this particular contract since it deals with non-sensitive data.

Tools Used

Manual code review.

Recommendations

Implement a self-destruct function that can be invoked by the contract owner.
