# 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.
