Block Time Estimator Overlay

WHAT IT DOES Block Time Estimator Overlay watches the current DeFi page for the user's wallet address, reads the current block time and block production rate from the blockchain via eth_getBlockByNumber, calculates the average block time over recent blocks, estimates the time until the next block based on current block timestamp and average block time, and displays an overlay with current block time, average block time, estimated time to next block, and execution recommendations when block times are unusually long or short. The tool connects to the user's wallet via window.ethereum, reads current block timestamps and block numbers, calculates average block time over recent blocks, estimates time to next block, and provides recommendations. WHERE IT RUNS The tool runs as a panel inside your browser on DeFi pages at https://app.uniswap.org/*, https://app.gmx.io/*, and https://app.aave.com/*. It works on Uniswap, GMX, and Aave pages where users may execute transactions. The tool connects to your real EVM wallet extension (MetaMask, WalletConnect, or any wallet injecting window.ethereum) to read on-chain data via eth_call and the ethers library loaded at runtime. No data is sent to any external server; all reads happen directly from the blockchain through your wallet provider. HOW TO USE Install the BotGentz extension, navigate to Uniswap, GMX, or Aave with your wallet connected, and open the Block Time Estimator Overlay panel. Set your block time alert threshold in seconds (default 15) — the tool will alert you when block times exceed this value. Set your average block time window in blocks (default 10) — the tool will use this many recent blocks to calculate the average. Choose your alert preference — Panel only, Browser notification, or Both. Toggle "Auto-check on page load" if you want the tool to analyze automatically when you open the panel. Click "Monitor Blocks" — the tool reads the current block timestamp and number, calculates the average block time over recent blocks, estimates the time until the next block, and displays a comprehensive analysis with recommendations. When block times are unusually long or short, the tool triggers alerts with block time details. The block monitor updates automatically every 10 seconds. Click "Refresh" to manually update the block time data. MECHANISM — BLOCK TIME DETECTION WITH AVERAGE CALCULATION AND NEXT BLOCK ESTIMATION This tool uses a block time detection engine that reads blockchain data and estimates future block times. The system first connects to window.ethereum and requests the user's wallet address. It reads the current block timestamp and block number via eth_getBlockByNumber. The tool fetches recent blocks to calculate the average block time over the configured window (default 10 blocks). The average block time is calculated using the formula: avgTime = (sum of block time differences) / (number of blocks - 1). The estimated time to the next block is calculated using the formula: nextTime = max(0, avgBlockTime - (now - currentBlockTimestamp)). The urgency classification uses a multi-tier system: SLOW (currentTime > alertThreshold OR avgTime > alertThreshold), FAST (currentTime < 8 AND avgTime < 10), or NORMAL. Recommendations are generated based on the block time status, helping users time their transactions for optimal execution. THE PANEL The BotGentz panel is fully draggable, allowing you to position it anywhere on your screen without obstructing the DeFi interface. It includes per-site position memory, so the panel returns to your preferred location each time you visit the exchange. 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 DeFi 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. This is a monitoring and analysis tool only — it does not execute transaction optimization automatically. The tool cannot guarantee that the displayed block times match the exact moment of execution due to network changes. It cannot account for block time variations during execution. It cannot predict future block time trends or optimal timing. It cannot read block data from all EVM chains. It cannot read private wallet information or transaction intentions. 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 block times and network conditions independently before executing any transactions based on the dashboard.
