Flash Loan Helper for Refinancing

WHAT IT DOES

Flash Loan Helper for Refinancing watches the current Uniswap V3 pool page, reads real-time reserves and liquidity data directly from the pool contract, and calculates the optimal flash loan amount for arbitrage or refinancing opportunities based on current liquidity depth and fee tiers. The tool extracts the pool address from the URL, reads the current sqrtPriceX96 and liquidity values via eth_call, calculates the maximum borrowable amount based on pool depth, applies the pool's fee tier (0.05%, 0.30%, or 1.00%), and computes the flash loan fee cost, minimum profit required based on your threshold, and the total cost of executing the loan. It then displays whether a profitable opportunity exists at current liquidity levels, with recommended loan parameters and expected profit margin percentage.

WHERE IT RUNS

The tool runs as a panel inside your browser on Uniswap V3 pool pages at https://app.uniswap.org/pool/*. It works on any Uniswap V3 pool page where the pool address is visible in the URL path. The tool connects directly to your real EVM wallet extension (MetaMask, WalletConnect, or any wallet injecting window.ethereum) to read on-chain data via eth_call. No data is sent to any external server — all reads happen directly from the Ethereum blockchain through your wallet provider.

HOW TO USE

Install the BotGentz extension, navigate to any Uniswap V3 pool page, and open the Flash Loan Helper for Refinancing panel. Set your minimum profit threshold percentage (default 0.5%) and maximum loan cap in ETH. Select your preferred auto-refresh interval from the dropdown or choose Manual. Click "Analyze Pool" — the tool reads the pool address from the URL, queries the pool contract for current sqrtPriceX96 and liquidity, calculates the maximum borrowable amount, applies the pool fee tier, and displays a complete analysis including loan parameters, fee cost, and whether a profitable opportunity exists at current liquidity. The panel updates automatically if you change the refresh interval. Review the results and use the recommended parameters for manual execution through your wallet or trading interface.

MECHANISM — REAL-TIME POOL STATE ANALYSIS WITH PRICE DEPTH CALCULATION

This tool uses a real-time pool state analysis engine that performs on-chain reads directly from the Uniswap V3 pool contract. The system extracts the pool address from the page URL and uses the ethers library loaded at runtime to create a Web3Provider connected to window.ethereum. It calls the pool contract's slot0 function to read the current sqrtPriceX96 value, and the liquidity function to read the current liquidity amount. From these values, the tool calculates the current token price using the formula price = (sqrtPriceX96 / 2^96)^2, and estimates the maximum borrowable amount based on the pool's liquidity depth. The fee tier is extracted from the URL or inferred from the pool's fee parameter. The system then applies your configured minimum profit percentage to determine the required profit amount, computes the flash loan fee based on the pool tier, and compares the total cost against the maximum borrowable amount to determine if a profitable opportunity exists. All calculations are performed client-side using real-time on-chain data, ensuring accuracy at the moment of analysis.

THE PANEL

The BotGentz panel is fully draggable, allowing you to position it anywhere on your screen without obstructing the Uniswap interface. It includes per-site position memory, so the panel returns to your preferred location each time you visit a pool page. Snap-to-edge functionality lets you dock the panel to any side of the browser window. The panel collapses to a compact icon when not in use and expands with a single click. You can resize it to your preferred dimensions, and pressing the Escape key instantly closes the panel. All interactions are smooth and intuitive, designed to work alongside your trading and analysis workflow.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension (such as MetaMask) already installed in your browser. EVM chains only — currently supports Ethereum mainnet and compatible networks. This is an analysis and calculation tool only — it does not execute transactions or flash loans. The tool cannot guarantee that calculated opportunities still exist at the time of user execution due to blockchain latency and mempool competition. It cannot detect sandwich attacks or front-running risks. All blockchain reads are performed directly through your wallet provider; no data is stored or transmitted beyond your browser. Websites change their layouts and content structures regularly; while we continuously update the extraction logic, some pages may require script updates. Always verify all calculations and opportunities directly on-chain before executing any transactions.
