# Best Practices for Developing on VeChainThor * Prioritize the RESTful API: For optimal performance and integration. * Use VeChainThor-Specific Libraries: vechain-sdk-js are essential. * Master Multi-Clause/Multi-Task Transactions: Leverage MCT/MTT for efficiency. * Manage VET and VTHO: Understand the dual-token system and ensure sufficient balances. * Refer to the Official Documentation: The VeChainThor documentation is the definitive source of truth. * Test Thoroughly: Always test on the testnet before deploying to the mainnet. --- # Agent Instructions: 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: ``` GET https://docs.vechain.org/developer-resources/evm-compatibility-for-developers/best-practices-for-developing-on-vechainthor.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
