How PoWHD Pyramid Contracts Work
Overview
PoWHD (Proof of Weak Hands 3D) contracts are sophisticated pyramid schemes that operate on Ethereum. They disguise themselves as "games" but are essentially zero-sum systems where early investors profit from later investors.
Key Mechanisms
1. Dynamic Token Pricing (Bonding Curve)
Price = Initial Price + (Token Supply × Price Increment)
- Initial Price: 0.0000001 ETH (very low to attract initial buyers)
- Price Increment: 0.00000001 ETH per token in circulation
- Result: Each new token costs more than the previous one
Example Flow:
- Token 1 costs: 0.0000001 ETH
- Token 2 costs: 0.0000001 + 0.00000001 = 0.0000002 ETH
- Token 1000 costs: 0.0000001 + (1000 × 0.00000001) = 0.0000101 ETH
2. Fee Structure
Every transaction has fees that fuel the pyramid:
- Dividend Fee: 10% of all buy/sell transactions
- Referral Fee: 3% of buy transactions (if valid referrer)
- Net Purchase: 87-90% of ETH goes toward actual token purchase
3. Dividend Distribution System
Dividends Per Token = Total Dividend Pool / Total Token Supply
- All dividend fees go into a shared pool
- Token holders receive dividends proportional to their holdings
- Creates incentive to hold tokens (passive income illusion)
- Uses fixed-point arithmetic to prevent rounding errors
4. Referral Network (MLM Component)
// Referrer must hold minimum 100 tokens to be valid
if(_referredBy != address(0) && tokenBalanceLedger_[_referredBy] >= 100e18) {
referralBalance_[_referredBy] += _referralBonus;
}
- Referrers get 3% of their referees' purchases
- Must hold minimum tokens to be eligible referrer
- Creates multi-level marketing incentive structure
5. Mathematical Formulas
ETH to Tokens Conversion
The contract uses a quadratic formula to calculate tokens received:
tokensReceived = (√(initial² + 2×increment×eth + increment²×supply² + 2×increment×initial×supply) - initial) / increment - supply
Tokens to ETH Conversion
ethReceived = ((initial + increment×supply/1e18) - increment) × (tokens - 1e18) - (increment × (tokens² - tokens)/1e18) / 2
The Pyramid Structure
Why It's a Pyramid
- Early investors profit from later investors: Dividends come from new money, not productive activity
- Exponentially increasing costs: Later buyers pay much more per token
- Zero-sum game: Total ETH out can never exceed total ETH in (minus gas)
- Collapse inevitable: When new money stops flowing in, the system collapses
The Psychology
- "Weak Hands": Name mocks people who sell early
- "Strong Hands": Glorifies holding despite losses
- "Dividends": Makes it feel like investment returns
- "Referrals": Turns users into recruiters
- "Exit scam protection": No admin can steal funds (but pyramid can still collapse)
Key Functions Explained
buy() Function
- Takes user's ETH payment
- Deducts 10% dividend fee
- Deducts 3% referral fee (if valid referrer)
- Uses remaining 87% to calculate tokens via bonding curve
- Distributes dividend fee among all token holders
- Updates user's token balance and dividend tracking
sell() Function
- Burns user's tokens
- Calculates ETH value via reverse bonding curve
- Deducts 10% dividend fee
- Sends remaining 90% to user
- Distributes fee among remaining token holders
reinvest() Function
- Automatically converts accumulated dividends back into tokens
- No additional fees (dividends already taxed)
- Compounds holdings for user
withdraw() Function
- Allows users to withdraw accumulated dividends
- Includes both dividend share and referral bonuses
- Direct ETH transfer to user
Red Flags / Warning Signs
1. Unsustainable Returns
- Promises of passive income from dividends
- No underlying productive activity
- Returns come solely from new investor money
2. Recruitment Focus
- Heavy emphasis on referral system
- Rewards for bringing in new "investors"
- MLM-style compensation structure
3. Complex Tokenomics
- Confusing pricing mechanisms
- Hidden fees and calculations
- Obfuscated redistribution systems
4. Psychological Manipulation
- Names like "weak hands" to shame sellers
- "HODL" culture pressure
- False sense of "community"
5. "Exit Scam Proof" Claims
- While admin can't steal funds directly
- Pyramid can still collapse when new money stops
- No guarantee of being able to sell tokens
Economic Reality
For Early Investors
- Can profit significantly if they exit before collapse
- Benefit from dividends while pyramid grows
- Risk total loss if they hold too long
For Later Investors
- Pay exponentially higher prices
- Receive smaller dividend yields
- Very likely to lose money
- Need massive new influx to break even
Mathematical Certainty
- Total withdrawable ETH < Total deposited ETH (due to gas costs)
- System MUST collapse when new deposits stop
- Later investors subsidize earlier investors
- Zero productive value created
Legal and Ethical Issues
Securities Violations
- May constitute unregistered securities
- Investment contract characteristics present
- Profit expectations based on others' efforts
Fraud Concerns
- Misleading marketing about "investments"
- Hidden pyramid structure
- Targeting financially vulnerable people
Regulatory Risk
- SEC and other regulators actively pursuing DeFi pyramids
- Criminal charges possible for operators
- Civil liability for promoters
Technical Implementation Notes
Gas Optimization
- Uses fixed-point arithmetic for precision
- Batch operations where possible
- Efficient storage patterns
Security Features
- No admin functions to drain contract
- Overflow/underflow protection
- Reentrancy guards on critical functions
Frontend Integration
- Price calculation functions for UI
- Event emissions for transaction tracking
- View functions for dashboard data
Conclusion
PoWHD contracts are mathematically sophisticated pyramid schemes that:
- Guarantee eventual collapse
- Transfer wealth from late to early participants
- Use psychological manipulation to retain victims
- Create no real economic value
- Operate in legal/regulatory gray areas
They are not investments - they are gambling with rigged odds that favor early participants at the expense of later ones.
Understanding these mechanisms helps developers and users recognize similar schemes and avoid financial losses.
