Pump.fun Anti-Fraud System
Overview
The Pump.fun system on Yume Exchange includes AI-powered anti-rugpull protection that automatically detects and blocks manipulation attempts, creator rugpulls, and coordinated dumps.
Yume Exchange does NOT use real money. All transactions use Yumes (🌸), the bot's virtual currency. Yumes CANNOT be converted to real money.
Security Features
1. AI Fraud Guardian
Intelligent system that analyzes each token in real-time and calculates a Risk Score (0-100) based on:
- Supply concentration
- Creator behavior
- Available liquidity fund
- Sales pattern
- Creator's rugpull history
Risk levels:
- LOW (0-20): Safe token ✅
- MEDIUM (20-40): Caution ⚠️
- HIGH (40-70): Elevated risk 🔶
- CRITICAL (70-100): Imminent rugpull 🚨
2. Holders Leaderboard
Total transparency of supply distribution:
- Top 10 Holders with supply percentage
- Special badges:
- 👨💻 DEV - Token creator
- 🐋 WHALE - Holders with more than 10% of supply
- Distribution Health Score (0-100%)
- Green > 70% - Healthy distribution
- Yellow 40-70% - Moderate concentration
- Red < 40% - High concentration (danger)
- Automatic warning when a holder has > 30%
Example:
| Rank | Holder | Balance | % Supply | Badge |
|---|---|---|---|---|
| #1 | abc123... | 50,000 | 25.0% | 👨💻 DEV |
| #2 | def456... | 30,000 | 15.0% | 🐋 WHALE |
| #3 | ghi789... | 15,000 | 7.5% |
3. Price Impact Calculator
Real mathematical calculation of your trade impact using exponential bonding curve:
Formula:
P = I₀ * e^(k * S)
Where:
- P = Price
- I₀ = 0.01 (initial price)
- k = 0.00005 (growth rate)
- S = Current supply
What you see:
- Price Impact: +8.34% (green < 5%, yellow 5-10%, red > 10%)
- Average Price: 0.000152 🌸
- Price After: 0.000165 🌸
- Total: 1,015 🌸 (with warning if impact > 10%)
BEFORE: ~0.xx% (false)
AFTER: +15.34% (real with warning)
4. Anti-Snipe Protection
Protection during the first 5 minutes after token creation:
- Buy limit: Maximum 1,000 tokens
- Visible timer: "3 minutes of anti-snipe protection remaining"
- Prevents: Bots hoarding supply in seconds
Error if you try to buy more:
🛡️ Anti-Snipe: You can only buy max 1000 tokens
in the first 5 minutes (3 min remaining)
5. Concentration Limits
Concentration limits to prevent manipulation:
- 30% maximum per individual holder
- 20% maximum for the creator
- Automatic blocking of purchases exceeding limits
Error if you try to concentrate:
❌ This purchase would give you 35.2% of supply
(max allowed: 30%)
6. Rugpull Detection
Automatic detection of creator rugpull attempts:
Triggers:
