OPTIMIZATION SUGGESTIONS

1- Loop on the dynamic variable (low severity).

If the user gets more parallel deposits his withdrawal transaction fee will cost more transaction fees because the loop on the dynamic variable is used in the ‘withdraw’ function.

In case of the GAS limit of exceeding the size of transaction withdraw is not possible.

Note:

This comment is relevant only if a user creates an excessive amount of parallel deposits (more than 100).

Referral System (Match Bonus)

This contract pays 9.1% referral commissions over 3 level

Level one: 5%
Level two: 2%
Level three: 2%
Return to the investor: 0.1% (if the user has a valid upline)

Notes:

Referral should be an active user. it means the referral address has at least one deposit
A referrer is specified once at the time of the first deposit and is assigned to the user without the possibility of changing. From each subsequent Deposit, the referrer will get his percent.
If a user has not a referrer all referral amounts transfer to owners.

Withdraw Limit:

users can only withdraw every 36 hours

Notes and Hints:

In this contract based on function “grant”, the user can send BNB to create a new deposit for another address and his address is upline.

function() external payable {

if (msg.value == 0) {

withdraw();

} else {

invest(0, 0); //default to buy plan 0, no referrer

}

}

Based on the above code if an address sends BNB directly to the contract address, a deposit will be created for him without a referral
If an address sends zero amount directly to the contract address withdraw function runs automatically.
