Explorer Data Export Automation Tool

WHAT IT DOES

This tool automates data exports from block explorers and RPC endpoints, enabling comprehensive extraction of on-chain data for analysis, reporting, and archival purposes. It supports exporting transaction data, logs/events, contract source code, and metadata across configurable block ranges. The tool validates contract verification status, queries historical transaction data, and generates structured previews of the exported data. Results are presented as a detailed export report with itemized counts, status indicators, and a JSON preview. This is essential for analysts extracting blockchain data, researchers building datasets, and teams maintaining contract documentation archives.

HOW TO USE

Connect your wallet (read-only, no transaction required) and select the target network. Enter the contract name and address, select the data type to export (Transactions, Logs/Events, Contract Source Code, or All Data), and specify the block range (start and end blocks). Click "generate export" and the tool will verify the contract, fetch the requested data from RPC and block explorer APIs, and generate a structured export. Results display a summary with contract details, export type, block range, and total item count, detailed export cards showing each data type with item count and status, and a JSON preview of the exported data. Use the report to verify data completeness, plan exports, and integrate with downstream analysis tools.

TECHNICAL MECHANISM

The exporter uses ethers.js v5.7.2 to perform a multi-stage data export process. First, it calls eth_getCode to verify the contract is deployed and uses block explorer APIs to fetch verification status and source code. The tool then queries eth_getLogs across the specified block range to retrieve transaction logs and event data. For each log entry, it extracts transaction hashes and uses eth_getTransaction and eth_getBlock to enrich the data with transaction details and block metadata. The tool organizes the exported data by type—transactions, logs, contract code, and metadata—and generates a structured JSON output with preview capabilities. For contract source code exports, the tool fetches from block explorer APIs (Etherscan, Blockscout, Sourcify) and includes ABI data when available. The export process includes validation steps to ensure data completeness, with status indicators (ok/warn/bad) for each data type based on verification status and data availability. Results are compiled into a structured report with detailed item counts, status indicators, and a JSON preview of the exported data.

WHAT IT CANNOT SEE

This tool cannot export data that is not accessible via RPC or block explorer APIs. It is limited by the RPC provider's rate limits and block range availability for historical data; very old blocks may be inaccessible on some endpoints. It cannot export data from private or permissioned chains that are not accessible via the provided RPC endpoints. The analysis relies on the accuracy and completeness of on-chain data and block explorer API responses; incomplete data may produce incomplete exports. It cannot analyze or export data for contracts that are not verified or have opaque implementation details where source code is not available. The tool is limited to the specific block ranges and contract instances that are accessible via RPC. It cannot guarantee that exports include all relevant data without comprehensive query planning—the tool provides a snapshot based on the specified block range. Export size may be limited by memory and performance constraints; large block ranges may require chunking and may not complete within the session limits.

PLEASE NOTE

This is a read‑only analytics tool—it never submits transactions or modifies contract state. It is designed for EVM‑compatible chains and works best with verified contracts. The export results are for informational and analysis purposes only and should be verified against the original on-chain data. Always review the exported data for completeness and accuracy before use in production systems. The tool's export capabilities are limited by the RPC provider's API constraints—consider using a dedicated archival node for large exports.
