I Built a Chrome Extension That Scans Solana Tokens for Rug Pulls

Tired of aping into tokens without checking if they're safe? I built a Chrome extension that instantly scans any Solana token for rug pull risks.

SOL Scanner Chrome Extension

Works automatically on:

• DexScreener (solana token pages)
• Birdeye (token pages)
• Solscan (token pages)

What It Checks (6-Point Analysis)

1. Mint Authority — Can they mint unlimited new tokens? (Revoked = safe)
2. Freeze Authority — Can they freeze your tokens? (Revoked = safe)
3. Metadata Mutability — Can they change the token name/image?
4. Top Holder Concentration — Does one wallet own >50% of supply?
5. Holder Count — How many unique holders?
6. Total Supply — Supply analysis

Risk Score

Each token gets a 0-100 risk score:

• 70-100: Low risk (green)
• 40-69: Medium risk (yellow)
• 0-39: High risk (red)

How It Works

1. Visit any token on DexScreener or Birdeye
2. Extension auto-detects the token mint address
3. Scans on-chain data via Helius RPC
4. Shows risk score + detailed breakdown in the popup
5. Click "View full analysis" for deep dive

Install (Free)
