DEX MEV Protection Toggle

WHAT IT DOES

DEX MEV Protection Toggle monitors the current DEX swap page, detects potential MEV sandwich attack risk based on trade size and market conditions, and toggles a protection mode that adjusts slippage and gas settings to reduce MEV exposure. The tool calculates a risk score based on trade size, price volatility, and gas activity, then displays the risk level — low, medium, or high — along with protection status. When protection is enabled, the tool automatically adjusts slippage and gas settings on the page to make your transaction less attractive to MEV bots.

WHERE IT RUNS

This userscript runs inside major DEX platforms including Uniswap, 1inch, and SushiSwap in your browser, powered by the free BotGentz extension. It operates entirely on the page you are viewing — it reads the swap state from the page and simulates mempool analysis through your wallet provider. The tool only modifies page UI settings (slippage and gas) and never signs transactions or moves funds.

HOW TO USE

Install the BotGentz extension, then install this userscript from the BotGentz catalogue. Navigate to a swap page on Uniswap, 1inch, or SushiSwap. Connect your wallet (MetaMask or any EVM-compatible wallet) — the tool uses your wallet to read on-chain data. Configure your settings — set the slippage multiplier, gas multiplier, minimum trade size for protection, and toggle auto-detection and notifications. Click "Start Monitoring" to begin. The tool will display the current risk level, protection status, and trade details. Use the "Enable/Disable Protection" toggle to manually control protection, or enable auto-detection to let the tool activate protection automatically when risk is detected.

HOW IT WORKS UNDER THE HOOD

The tool extracts the trade amount and token pair from the page's DOM. It then calculates a risk score based on three factors: trade size relative to the configured minimum (larger trades are more attractive to MEV bots), price volatility (simulated from recent price changes), and gas activity (simulated mempool congestion). The total risk score is weighted and mapped to a risk level — low, medium, or high. When protection is enabled and risk is detected, the tool finds the slippage input field on the page and adjusts it by multiplying the base slippage (0.5%) by the configured slippage multiplier. The gas multiplier is also applied to the gas price setting when available. All settings are persisted locally using GM_setValue and the tool updates every 5 seconds.

THE PANEL

The tool runs in the BotGentz panel, a draggable floating interface that stays on top of the page. You can drag the panel by its header, collapse it to a small bubble, and resize it. The panel remembers its position per site, so it stays where you left it when you return to the DEX. Press Escape to close the panel when you are done. The panel includes a wallet connection button, protection status display, risk level display, trade details, manual protection toggle, slippage and gas multiplier settings, minimum trade size, auto-detect toggle, notification toggle, and start/stop monitoring button.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension (MetaMask or similar) already installed in your browser. The tool works on EVM chains only — Ethereum, Polygon, Arbitrum, Optimism, and other EVM chains are supported. The tool is read-only for on-chain data and only modifies page UI settings — it never signs transactions or moves funds. The MEV detection is simulated and may not detect all MEV strategies. Protection cannot guarantee complete safety from MEV attacks, especially if attackers use private mempools. DEX platforms frequently update their interfaces — if the tool stops working, check for an updated version or report the issue. Always review adjusted slippage and gas settings before confirming transactions.
