Hey @fuel! You can structure your project by creating an `interface` folder that contains the ABIs for all necessary contracts. The directory layout would look something like this:

```auto
Project/
        ├── contracts/
        │ ├── AMM/
        │ │ └── main.sw
        │ └── Exchange/
        │ └── main.sw
        └── libraries/
            ├── interface.sw
            └── data_structures.sw

```

A prime example of this structure in action is the AMM project found in the sway applications repository. In this project, all ABIs are organized within a [separate `libraries` folder](https://github.com/FuelLabs/sway-applications/blob/master/AMM/project/libraries/src/interface.sw) and imported as required.

Specifically, in the AMM contract, which utilizes both interfaces, you can see this import process in action. The relevant code can be found [here](https://github.com/FuelLabs/sway-applications/blob/master/AMM/project/contracts/AMM-contract/src/main.sw#L8). This approach streamlines the workflow by ensuring that changes are centralized and don’t need to be duplicated across multiple locations.
