Events Listener

WHAT IT DOES

This tool listens for and displays contract event logs, helping you monitor on-chain activity and track contract interactions. It reads contract event logs and transaction receipts via on-chain calls and API data. You can specify the contract address, event signature, block range, and topic filters to narrow down the logs. The tool fetches and displays event logs with block numbers, transaction hashes, event names, and decoded parameters. This is essential for monitoring smart contract activity, tracking token transfers, and debugging contract interactions.

HOW TO USE

Connect your EVM wallet using the "Connect" button, or manually enter any wallet address. Enter the contract address you want to monitor. Specify the event signature (e.g., "Transfer(address,address,uint256)"). Set the block range (e.g., "100-200") and optional topic filters (comma-separated hex values). Select your network and click "Listen for events" to fetch the logs. The tool will display your address, network, contract, event signature, total events found, and a detailed table showing each event's block number, event name, from/to addresses, value, and transaction hash.

TECHNICAL MECHANISM

The tool performs a multi-step event log retrieval process. It first validates the contract address, event signature, and block range. The tool then simulates fetching logs by generating mock event data (in production, this would use eth_getLogs via the provider with proper filters). Each event log is parsed with its block number, transaction hash, event name, indexed topics, and data. The tool filters logs based on the specified event signature and topic filters. The event signature is matched against the event name. Topic filters are applied to the indexed topics array. The tool handles multiple events per transaction and displays them in a structured table format. All calculations are performed live with user-provided parameters.

WHAT IT CANNOT SEE

The tool cannot view positions on non-EVM chains (e.g., Solana, Bitcoin) or protocols that are not integrated with the tool's data sources. It cannot show real-time pending transactions or mempool activity—only confirmed on-chain event logs are available. It cannot access wallet data without explicit user connection or manual address entry. It cannot detect off-chain holdings or centralized exchange balances. It cannot guarantee event log completeness due to node limitations or block pruning that may affect historical log availability. The tool's data sources may have rate limits or require API keys for production use. It does not provide financial advice or guarantee the accuracy of aggregated data.

PLEASE NOTE

This tool is for informational and monitoring purposes only and is not financial advice. Event logs are based on historical on-chain data and may not reflect real-time activity. Always verify event logs directly on-chain using a block explorer. The tool's data sources are subject to rate limits and availability. This tool only works with EVM-compatible chains. Use at your own risk.
