Reorg Risk Overlay

WHAT IT DOES

Reorg Risk Overlay is a DeFi tool that watches the current page for pending transaction hashes, block confirmations, or transaction receipts, then calculates and displays the risk level of a chain reorganization (reorg) affecting the displayed transactions. It scans the page for transaction hashes, queries the connected EVM chain for current block height and fork history, and calculates reorg risk based on the depth of confirmations and current network conditions. The tool provides a visual overlay indicator (low/medium/high) for each transaction, helping you assess whether a transaction is safe from being reorganized out of the chain.

WHERE IT RUNS

This tool operates as a panel within the BotGentz browser extension, available for Chrome, Firefox, Edge, and Brave. It works on any webpage displaying transaction hashes, block confirmations, transaction receipts, or similar blockchain data. Common sources include Etherscan, block explorer pages, DEX interfaces, and wallet transaction history pages.

HOW TO USE

Navigate to any page that displays transaction hashes, block confirmations, or transaction receipts. Open the BotGentz extension and select Reorg Risk Overlay from the tool menu. The panel will appear on the side of your browser. Click the "Connect Wallet" button to connect your EVM wallet (MetaMask or compatible). Click the "Scan Transactions" button to detect transaction hashes on the page. Click the "Refresh Risk" button to fetch current network conditions and calculate reorg risk for each transaction. The panel will display each transaction with a risk label (Low, Medium, or High) and a color-coded indicator. You can set a risk threshold and enable alerts to be notified when risk levels change.

TECHNICAL SECTION — REORG RISK CALCULATION

This tool uses a multi-stage pipeline to assess reorg risk. First, it scans the page DOM for transaction hashes using pattern matching (0x + 64 hex characters) and checks for data attributes that may contain hash and block number information. Second, it connects to the EVM network via window.ethereum to query the current block height using eth_blockNumber and retrieves block data using eth_getBlockByNumber to detect uncle blocks and potential fork indicators. Third, it calculates the confirmation depth for each transaction by comparing the transaction's block number (if available) against the current block height. Fourth, it applies a heuristic model that factors in confirmation depth and network health indicators. On Ethereum, reorgs of 1-2 blocks are relatively common, 3+ blocks are rare, and 20+ blocks are considered extremely safe. The tool assigns risk scores based on this model: 0-1 confirmations (Very High), 1-3 confirmations (High), 3-5 confirmations (Medium), 5-10 confirmations (Low), and 10+ confirmations (Very Low). Network health factors, such as uncle block frequency and recent fork history, are also considered to adjust the risk score. The final risk level is displayed as a color-coded indicator in the panel.

THE PANEL

The side panel is designed for seamless integration into your browsing workflow. You can drag it to either side of the window, and it remembers your preferred position per website. It supports snap-to-edge behavior and can be collapsed to a small tab for minimal distraction. The panel is resizable horizontally and vertically, with a minimum width of 280px and maximum of 600px. Pressing the Escape key closes the panel. All settings are saved locally.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension (such as MetaMask) already installed in your browser. It works with EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, etc.). Reorg risk is probabilistic based on current network conditions and historical patterns. The tool cannot definitively predict if a reorg will occur or when. It relies on public chain data that may have latency. Some chains do not expose fork metrics, which may affect risk calculation accuracy. Websites change their transaction display formats frequently, and extraction scripts may need periodic updates. This tool does not store or transmit page content except for the transaction hashes sent to the EVM network to query block data. No browsing history or personal data is collected or retained.
