Smart Contract Calculation

Daily profits are calculated automatically: userInvestment * dailyRate / 100
Profits accumulate daily and can be withdrawn at any time. Capital can only be withdrawn after plan completion.

Core Contract Functions

invest()
PUBLIC
Description
Creates a new investment plan for the user
Parameters
amount (USDT), plan (0-7 representing 7-180 days)
Security
Validates minimum investment (varies by plan), checks plan validity, handles referral bonuses
withdraw()
PUBLIC
Description
Withdraws profits from completed investment cycles
Parameters
None - automatically calculates available profits
Security
Time-locked withdrawals, validates ownership, prevents double withdrawals
withdrawCapital()
PUBLIC
Description
Withdraws original investment after plan completion
Parameters
investmentId - specific investment to withdraw
Security
Only allows withdrawal after plan completion, validates ownership
claimReferralBonus()
PUBLIC
Description
Claims accumulated referral bonuses
Parameters
None - claims all available bonuses
Security
Validates bonus availability, prevents double claims
getUserInvestments()
PUBLIC
Description
Returns all user investments and their status
Parameters
userAddress - address to query
Security
Read-only function, no state changes

Function Access Control

All user functions are public and can be called by anyone. Owner-only functions are clearly marked and limited to contract administration. No owner function can access user funds directly.

Referral System Implementation

How Referrals Work

1. Registration with Referrer
When users register via a referral link, their referrer is permanently stored in the contract
2. Investment Triggers Bonuses
Each time a user's investment generates profit, referral bonuses are automatically distributed
3. Level-based Percentages
Different percentages for each level (L1: 20%, L2: 10%, L3-7: 5%, L8-10: 3%, L11-17: 1%)
4. Investment-based Unlocking
Users unlock more referral levels by increasing their total investment amount

Technical Implementation

mapping(address => address) referrers;
Stores each user's direct referrer permanently
uint256[17] REFERRAL_PERCENTAGES;
Fixed percentages for each of the 17 referral levels
function getUserReferralLevels(user)
Calculates how many levels user can earn from based on investment
function distributeReferralBonuses()
Automatically called when profits are generated
