Community Blocklist Cross-Checker

WHAT IT DOES

Community Blocklist Cross-Checker is your comprehensive transaction security tool that validates contract addresses against multiple community blocklist sources simultaneously. It intercepts pending transaction details from confirmation pages, extracts the target contract address, and cross-references it against multiple blocklist sources including local databases, simulated external APIs, and user-submitted lists. The tool displays a consolidated blocklist status with source attribution and conflict resolution, showing all blocklist entries that match the contract across different sources. It provides clear "Clean" (green), "Flagged" (red), and "Conflicting" (yellow) status indicators, supports multiple blocklist source selection and prioritization, and sends immediate alerts when a contract is flagged by any source.

WHERE IT RUNS

This script runs on all major DEX interfaces including Uniswap (app.uniswap.org), SushiSwap (app.sushi.com), Curve (curve.fi), Balancer (balancer.fi), 1inch (1inch.io), CowSwap (cow.fi), and major NFT marketplaces including OpenSea (opensea.io), Blur (blur.io), LooksRare (looksrare.org), Zora (zora.co), Rarible (rarible.com), and Foundation (foundation.app). It works on transaction confirmation pages, wallet approval dialogs, and any page displaying pending transaction details.

HOW TO USE

Install the script through the BotGentz userscript manager. Click "Connect Wallet" to link your EVM wallet extension. Navigate to any supported DEX or marketplace and initiate a transaction. When the confirmation dialog appears, the tool automatically detects the contract address and performs a cross-check across all enabled blocklist sources. The panel displays a consolidated status—Clean (green), Flagged (red), or Conflicting (yellow)—along with a detailed breakdown showing each source's result. Review the source attribution to understand which blocklists flagged the contract and why. The tool shows flagged count, clean count, and total sources checked, providing full transparency into the cross-check results.

MULTI-SOURCE BLOCKLIST AGGREGATION ENGINE WITH CONFLICT RESOLUTION

Unlike single-source blocklist checkers that only provide one opinion, this tool implements a multi-source aggregation engine that collects and reconciles results from multiple independent blocklist sources. The engine queries each configured source (local database, community lists, user submissions) for the target contract address, then aggregates the results into a consolidated status using a conflict resolution algorithm. If any source flags the contract, the overall status becomes "Conflicting" (yellow); if multiple sources flag it, the status escalates to "Flagged" (red); if all sources report clean, the status is "Clean" (green). The tool provides source attribution for each result, showing which specific blocklist flagged the contract and the reason provided. The priority system allows users to configure which sources take precedence in the event of conflicting results, ensuring the most trusted sources have greater weight in the final decision.

THE PANEL

The floating panel is fully draggable and snap-to-edge enabled. You can collapse it to a compact bubble when not in use, resize it to your preferred dimensions, and it remembers its position across page loads using persistent storage. Press Escape to quickly dismiss the panel. The panel displays the contract address, consolidated status with color-coded indicator, source summary (flagged/clean/unknown counts), and a detailed breakdown of each source's result with reason.

PLEASE NOTE

This script requires the free BotGentz extension to be installed in your browser—it does not run as a standalone extension. You also need a real EVM wallet extension already installed and configured for transaction interception. The tool cannot access all community blocklist sources due to API limitations and relies on the page exposing contract address in a detectable format. Simulated external sources may not reflect real community lists. Different sources may have conflicting entries. No user data is collected or transmitted—all blocklist check history stays local in your browser storage. The tool provides security awareness assistance but does not guarantee detection of all malicious contracts.
