• Cross-Validation Engine: Analyzes relationships between indicators (neutralized/amplified/contextual)
• Dynamic Risk Scoring: Weighted scoring system adapted to token type
• Fatal Finding Detection: One-strike rules for critical vulnerabilities

Supported Chains

• Ethereum (chain_id: 1)
• BNB Smart Chain (chain_id: 56)
• Polygon (chain_id: 137)
• Arbitrum One (chain_id: 42161)
• Base (chain_id: 8453)
• Optimism (chain_id: 10)
• Avalanche C-Chain (chain_id: 43114)
• Solana (chain_id: solana)

Installation

git clone https://github.com/ZorroShao/anti-rug.git
cd anti-rug
pip install -r requirements.txt

python scripts/check_token.py --chain_id 56 --contract_address 0x...

Scenario Classification

Scenario A: Pegged/Stable Assets

Examples: USDT, USDC, WETH, WBNB

• Mintable: ✅ Expected for peg maintenance
• Owner: ✅ Institution custody is normal
• Blacklist: ✅ Compliance requirement

Scenario B: Ecosystem Tokens

Examples: UNI, AAVE, established DeFi

• Proxy: ✅ Acceptable for upgradeability
• Treasury: ✅ Protocol-owned liquidity expected

Scenario C: Meme/Unknown Tokens

• All permissions: ⚠️ Treated as potential rug tools
• Strictest evaluation applied
