BNBInfinity Smart Contract Analysis

Issues

1. Correctness and Functionality

• Tariff Initialization: Tariffs (7–30 days) start at 119% daily, increasing 5% per day (up to 234%).
  
• Payout Calculation: Formula:
  Code:

  dep.amount * (to - from) * tarif.percent / tarif.life_days / 8640000
  Issue: Divisor 8640000 is incorrect (should be 86400000), undercalculating payouts by 100x.
  
• Referral System: 5-level bonuses (5%, 3%, 2%, 1%, 0.5%).
  Issue: Invalid upline defaults to owner, centralizing profits.
  
• Deposit Limits: Min 0.01 BNB, max 100 deposits/address.
  Issue: Arbitrary limit; users can bypass with multiple addresses.
  
• Owner Fee: 10% of deposits sent to owner.
  Issue: High fee reduces payout funds.

2. Security Vulnerabilities

• Reentrancy: Safe, transfer limits gas, state updates before calls.
• Unbounded Loops: Deposit loop (max 100) may be gas-intensive. Referral loops (5) are safe.
  
• Owner Privileges:
  Issue: No owner transfer or pause; compromised key risks funds.
  
• DoS:
  Issue: Repeated small deposits could inflate gas costs, mitigated by 0.01 BNB minimum.
  
• Timestamp Dependency:
  Issue: block.timestamp for payouts; minor miner manipulation possible.
  
• Ether Handling: invest and invest(address to) refund/forward BNB without state updates.
  Issue: Redundant, confusing functions.
  
• Missing Reinvest:
  Issue: reinvest is empty, breaking expected functionality.

3. Gas Optimization

• Issue: High storage use (Player, arrays); loops could cache reads.
• Note: Constants (BONUS_LINES_COUNT, ref_bonuses) are gas-efficient.

4. Missing Features

• Issue: No pause, upgradeability, or event for owner fees.

Summary

• Critical: Incorrect payout divisor, redundant invest functions, empty reinvest.
• Moderate: Owner centralization, timestamp dependency, gas costs for many deposits.
• Low: Missing pause/upgradeability, arbitrary deposit limit.

This contract does not support direct withdrawal of the initial deposit. Instead, payouts are distributed as dividends, calculated based on the tariff and duration. Withdrawals are only possible if you have accumulated dividends or referral bonuses.
