Flipside Crypto Query Tool

WHAT IT DOES

Flipside Crypto Query Tool provides a powerful interface for querying blockchain data through Flipside's comprehensive API. Build and execute SQL queries to retrieve token transfers, transaction history, smart contract interactions, DEX trades, lending positions, governance activity, wallet behavior, bridge activity, NFT sales, and custom query results across multiple EVM chains. The tool translates your selections into optimized SQL queries and presents the results in a structured, readable format. Export query results as JSON or copy the underlying SQL for reuse. This is an essential utility for data analysts, researchers, and developers who need to extract and analyze on-chain data without writing complex SQL from scratch.

HOW TO USE

1. Connect your Web3 wallet (Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, or any EVM-compatible chain).

2. Select the network that matches your target chain from the dropdown.

3. Choose a query type: token transfers, DEX trades, wallet activity, lending positions, NFT sales, bridge activity, or custom SQL.

4. Enter a wallet address or contract address to filter the query results.

5. For custom queries, write your own SQL using Flipside's table schemas.

6. Click "build & execute query" to send the request to Flipside's API.

7. Review the results displayed in a structured table format.

8. Use the "copy JSON" button to export raw data or "copy SQL" to reuse the query elsewhere.

TECHNICAL MECHANISM

Flipside Crypto Query Tool constructs SQL queries dynamically based on your selected query type, network, and address. The tool maintains a mapping of chain IDs to Flipside's table names (ethereum, polygon, arbitrum, optimism, bsc, avalanche) and builds queries using Flipside's standardized schema with proper table prefixes and column names. For predefined query types, the tool generates optimized SQL with appropriate WHERE clauses, ORDER BY statements, and LIMIT constraints to ensure efficient execution and prevent timeouts. For custom queries, the tool passes your SQL directly to the Flipside API without modification. The tool simulates the API request flow, including authentication headers and pagination handling for large result sets. Results are parsed from Flipside's JSON response format, with proper type handling for numeric values (big integers, decimals), timestamps (ISO 8601), and blockchain addresses (hex strings). The tool includes built-in error handling for common SQL syntax issues, table not found errors, and API rate limit responses, providing clear feedback to users. The query builder intelligently handles address filtering by detecting whether the input is a wallet address or contract address and adjusting the WHERE clause accordingly.

WHAT IT CANNOT SEE

This tool is a frontend for the Flipside API — it does not validate data accuracy, verify completeness, or detect inconsistencies between Flipside's indexed data and actual on-chain state. The tool cannot guarantee that query results reflect real-time chain state or that Flipside's data sources have been indexed correctly. It cannot ensure historical data completeness or consistency across different chains. The tool cannot predict query execution time or API availability, and it cannot handle large result sets beyond Flipside's pagination limits. All data is presented as provided by Flipside — if the API returns stale, incomplete, or incorrect information, this tool will display it without warning. The tool cannot validate that custom SQL queries are syntactically correct before execution or prevent query timeouts. It cannot detect if Flipside's indexing has gaps for certain time periods or if data sources have been deprecated. The tool cannot export data for non-EVM chains or interact with private networks.

PLEASE NOTE

Flipside Crypto Query Tool supports EVM-compatible blockchains only (Ethereum Mainnet, Goerli, Polygon, Arbitrum One, Optimism, BNB Smart Chain, Avalanche C-Chain, and others via network selection). The tool requires a Flipside API key — in this implementation, it uses a simulated key for demonstration purposes. For production use, you must provide your own Flipside API key. The tool never submits transactions or signs messages; it is strictly read-only. Query performance depends on Flipside's API response times and your network connection. For complex custom queries, result sets may be truncated due to Flipside's limits; consider using pagination or limiting result rows with LIMIT clauses. Some chain data may have limited historical coverage depending on Flipside's indexing schedule.
