Contract BSC


Highlights of the process

✅BEP-20’s Conformance

✅ No mint function

Privileged Functions

1️⃣ The contract contains the following privileged functions that are restricted by onlyOwner modifier:

2️⃣ The owner can toggle the liquidity addition mechanism:

3️⃣ ⚠️🔴The owner of the contract can withdraw any BNB/tokens sent to the contract by calling:

4️⃣️⃣ The owner can set the following:

5️⃣ The owner can control the number of tokens that can be sold/bought in a single transaction.


Issue #1 |🔍 Location swapAndLiquify |Logical Issue | 🟠 Medium Severity | Status: Not Fixed ❌


The swapAndLiquify function converts half of the contract’s tokens to BNB. The other half of the tokens are used for liquidity addition. The price of the token drops after executing the first conversion, having said that the other half of tokens require less than the converted BNB to be paired with it when adding liquidity.


Our recommendation is to use the leftover BNBs for buyback.

⚠️ The team fixed this issue by implementing a transfer function that sends the BNB that were stuck in the contract to an address the owner desires.

⚠️ Note that when swapAndLiquified() function takes place, the tokens that were accumulated as fees are sold to bnb. When this scenario occurs, it may cause a significant decrease in the token price.

Issue #2 | 🔍 Location addLiquidity|Owner Capabilities| 🔴 High Severity | Status: Fixed ✅


The recipient of the newly created LP tokens is the owner of the contract. The newly created LP tokens are unlocked.


Our recommendation is to change the recipient of the newly created LP tokens to the contract in order to ensure that the LP tokens are locked. Over time the owner address will accumulate a significant portion of the LP tokens.

✅ The team fixed this issue by sending the received bnb to burnAddress

Issue #4 | 🔍 Location APEx | Gas Optimization | 🟢 Informational Severity | Status: Not Fixed ❌


The public function lpBalance should be declared as external.


These functions are only called outside the contract consider using external attribute instead of public.

Vulnerability Summary


The contract has one low severity issue. The low severity issue is related to the fact that leftover bnb from liquidity addition can be withdrawn by the owner, instead of benefit the investors.
