HighMissing Update on `userPopupAmount`balance · CertiK · 18 Dec 2024Fixed
The `topup` function in `TopUpV1` is designed to enable users to send tokens to a recipient address while keeping a record in `userPopupAmount`. However, the following statement only performs the calculation without updating the `userPopupAmount` mapping: ```solidity=104 userPopupAmount[msg.sender][erc20_topup_token].add(topup_amount); ```
Open the reportLowInherited Contracts Not Initialized In Initializebalance · CertiK · 18 Dec 2024Fixed
Contract `TopUpV1` extends `ReentrancyGuardUpgradeable`, but the extended contract is not initialized by the current contract. Generally, the initializer function of a contract should always call all the initializer functions of the contracts that it extends.
Open the reportLowInvalid Whitelist Token Validationbalance · CertiK · 18 Dec 2024Fixed
The `topup` function intends to validate user payments to ensure they involve a whitelisted token. However, the current `has_coin` check only verifies if the token appears in the `white_tokens` mapping and does not confirm whether the token is still valid. As a result, a token that has been marked as invalid might still be treated as valid.
