  • Volatility measured over 15min + 1h windows
  • Volume ratio compared to 24h rolling average
  • Multipliers combine: 0.8x to 5.6x range
  • Circuit breaker caps at 7.5% absolute maximum

Quick Start Guide

Deploy in 3 easy steps

Follow these simple steps to create your protected pool.

  • Step 1: Select your network above and click "Deploy"
  • Step 2: Select your token to pair with the native token
  • Step 3: ⚠️ IMPORTANT: Re-enable "Dynamic Fee" toggle (Uniswap resets it)
  • Step 4: Set your price range and add liquidity
  • Done! Your pool is protected with anti-bot + dynamic fees
⚠️ Don't Forget: Enable Dynamic Fees
After selecting your token, make sure the "Dynamic Fee" toggle is ON. Without it, you'll only get basic anti-bot protection.
