The explorer interfaces with the latest protocol versions: ```plaintext plaintextCopyNode Version: 7.1.0 Middleware Version: 1.91.1 ``` ### Access Points #### Production Environment ``` Copyhttps://aescan.io ``` #### Testing Environment ``` Copyhttps://testnet.aescan.io ``` ### API Integration æScan leverages the æternity middleware API for data retrieval and processing. Key endpoints include: ```javascript javascriptCopy// Block data retrieval GET /middleware/blocks/latest GET /middleware/blocks/hash/{hash} GET /middleware/blocks/height/{height} // Transaction queries GET /middleware/transactions/hash/{hash} GET /middleware/transactions/account/{address} // State channel information GET /middleware/channels/active GET /middleware/channels/transactions/{channel_id} ``` ### Development Resources #### API Documentation * Node API: Comprehensive documentation for direct node interaction ``` Copyhttps://docs.aeternity.io/node ``` * Middleware API: Extended functionality for building applications ``` Copyhttps://docs.aeternity.io/middleware ``` #### WebSocket Support æScan maintains WebSocket connections for real-time data updates. Example connection: ```javascript javascriptCopyconst ws = new WebSocket('wss://mainnet.aeternity.io/mdw/websocket'); ws.onmessage = (event) => { const data = JSON.parse(event.data); // Handle real-time updates }; ``` #### Hyperchain Integration The explorer is being enhanced to support Hyperchains, æternity's scaling solution. Developers will be able to: * Track cross-chain transactions * Monitor Hyperchain validator activity * Access Hyperchain-specific metrics * Query state across multiple chains For developers looking to build applications on æternity, æScan's infrastructure provides a reliable reference implementation for blockchain data access and processing. The codebase demonstrates best practices for handling æternity protocol interactions and real-time blockchain data management. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.aeternity.com/aeternity-developer-tools/data-and-analytics/aescan.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
