# Concepts - [Data Sources](https://docs.blocktorch.xyz/concepts/data-sources.md): At Blocktorch we believe a hollistic approach to DevOps in web3 is necessary, so instead of pure smart contract observability we are integrating with multiple layers of the architecture of web3 - [EVM Chains](https://docs.blocktorch.xyz/concepts/data-sources/evm-chains.md) - [Roll-ups](https://docs.blocktorch.xyz/concepts/data-sources/roll-ups.md) - [Local forks](https://docs.blocktorch.xyz/concepts/data-sources/local-forks.md) - [Setup Hardhat fork](https://docs.blocktorch.xyz/concepts/data-sources/local-forks/setup-hardhat-fork.md) - [Setup managed Hardhat Fork](https://docs.blocktorch.xyz/concepts/data-sources/local-forks/setup-managed-hardhat-fork.md) - [Hardhat forking API](https://docs.blocktorch.xyz/concepts/data-sources/local-forks/hardhat-forking-api.md): Through this API, users can manage Hardhat instances dynamically, providing a seamless integration for continuous development and testing. - [Smart Contracts](https://docs.blocktorch.xyz/concepts/data-sources/smart-contracts.md) - [Adding smart contracts](https://docs.blocktorch.xyz/concepts/data-sources/smart-contracts/adding-smart-contracts.md) - [Custom Event Data](https://docs.blocktorch.xyz/concepts/data-sources/custom-event-data.md) - [Oracles](https://docs.blocktorch.xyz/concepts/data-sources/oracles.md) - [Account Abstraction modules](https://docs.blocktorch.xyz/concepts/data-sources/account-abstraction-modules.md) - [Navigating the AA Explorer](https://docs.blocktorch.xyz/concepts/data-sources/account-abstraction-modules/navigating-the-aa-explorer.md) - [Decentralized Datastorage](https://docs.blocktorch.xyz/concepts/data-sources/decentralized-datastorage.md) - [React Frontends](https://docs.blocktorch.xyz/concepts/data-sources/react-frontends.md) - [Querying data](https://docs.blocktorch.xyz/concepts/querying-data.md) - [Telemetry](https://docs.blocktorch.xyz/concepts/telemetry.md) --- # 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.blocktorch.xyz/concepts.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.
