createNewDAOMembership function, there is no validation to ensure that the price of each tier is greater than zero. Allowing tiers with a zero price may not align with the intended business logic and could lead to unintended free memberships.

Code Snippet:

for (uint256 i = 0; i < tierConfigs.length; i++)

{

require(tierConfigs[i].minted == 0, "Invalid tier config"); // Missing validation: require(tierConfigs[i].price > 0, "Tier price must be greater than zero.");

dao.tiers.push(tierConfigs[i]);

}

Explanation:

Tiers with a price of zero enable users to join the DAO for free.

If the DAO does not intend to offer free memberships, this could be a problem.

Recommendation

• Add Validation for Tier Price:

  require(tierConfigs[i].price > 0, "Tier price must be greater than zero.");

  If zero-priced tiers are acceptable in certain contexts (e.g., free membership levels), make this explicit in the business logic and document it clearly.
