Contract Sources

Browse verified contract source files and jump between symbol definitions.

# Contract Sources

Browse verified contract source files and jump between symbol definitions.

**Sources** shows the file tree on the left and code on the right. Files you open remain in tabs.

## Interface

| Area    | Description                                                            |

| Sources | Browse the file tree; use the input at the top to filter by file name. |
| Editors | View opened files, switch between tabs, or close them.                 |
| Search  | Press `⌘ K` (`Ctrl K` on Windows/Linux) to search all source code.     |

## Example

<span className="text-text-secondary block text-right text-xs">
  This example uses local Uniswap V3 Pool files and does not access on-chain
  data.
</span>

1. Open `UniswapV3Pool.sol`.
2. Find `flash`.
3. Hold `⌘` (`Ctrl` on Windows/Linux) and click `IUniswapV3Pool` to jump to the interface file.
4. Enter `IUniswap` in the filter to keep only relevant files; clear it to restore the full list.

## Go to definition

Hover over a function, contract, variable, or interface name, then hold `⌘` / `Ctrl` and click to open the file containing its definition at the relevant line. If several matches exist, a list of choices appears.

Right-click and select **Find All References** to see where the name is used.

## Notes

* Unverified contracts have no source code to show; use Trace or Bytecode Debugger instead.
* For proxy contracts, the implementation contract's source code is shown first.
* Go to definition and reference search require an AST. Without one, you can still browse and search source code.
