# Step debugger

Blocktorch's Step Debugger simplifies debugging by providing detailed insights into blockchain transaction execution. It helps identify and solve issues quickly, enhancing your development speed.

### Getting started with the step debugger

#### Navigating to the debugger

To use the Debugger, you need to start from a specific transaction. 

1. Either go to the [Search](/use-cases/searching.md) page from the navigation to choose a transaction or search for a transaction hash in the search bar on top, or click a specific contract in the contract overview to see the contract's logs
2. Click the `🪲`` `**`Debugger`** button located at the top right of the [log details](/use-cases/searching/logs/log-details.md).

#### Using the step debugger&#x20;

The Debugger interface is comprised of three main sections:

* **Execution trace** (left): Displays the sequence of calls made during the transaction, , which can be used to navigate through the code.
* **Smart contract source code** (top right): Shows the code of the contract being interacted with. If a contract is not added to the project and thus the ABI is unknown we will not be able to show the full decoded data,
* **Call information** (bottom right): Provides detailed info about the current call.
