Optimization suggestions


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

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

In case of exceeding TRON limit of 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 300).




2- Leader Prize

Based on the function “_calculateReferrerReward” in case of a user has just one or less subset than prize table level and his subset invest a large amount in one deposit, the user does not receive all prizes.


the main user should have more deposit count in his subnet equal to the prize table.

Notes and Hints:

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


function() external payable {

if (msg.value == 0) {


} else {

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



  • Based on top code if an address sends TRX 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.



require(uid2Investor[uid].timer < now, “withdrawal is available only once every 48 hours”);


uid2Investor[uid].timer = now + 48 hours;


  • Based on top code, users can only withdraw every 48 hours
