The system used is called ROI and must be considered as HIGH-RISK.

Users principal deposits cannot be withdrawn, users can get dividends and referral commission. Dividends are paid from deposits of other users. Do always invest with proper knowledge and investigation.


Optimization suggestions

Loop on the dynamic variable (low severity).

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

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


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

once a day





once a day


  • The minimum deposit amount is 5 MATIC
  • Users can only withdraw or reinvest once a day
  • There is a 5% bonus on reinvesting for dividends of the second plan





Referral System (Match Bonus)

The contract pays a 5% referral commission over 1 level

  • Level 1:           5%


  • Referral should be an active user; it means the referral address has at least one deposit
  • The 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 percentage.
  • If a user has not had a valid upline, a total referral commission will be sent to the owner


SEED System

Users will receive 1% of their referral daily dividends.

For example, if your referral user invests 1000 Matic in the first plan, he can withdraw 160 Matic daily and the seed system will give you 1.6 Matic as a reward.

It will be applied when your referral tries to withdraw and 1% of the withdrawable amount will be added to your available balance.
