# Gateway Contracts

### Purpose

Gateway contracts are essential components that enable different blockchains to communicate with each other. They handle the secure and efficient transfer of data and messages between networks, making cross-chain interactions possible.

NOTE: Developers building cross-chain contracts do NOT need to interface with Gateway contracts. This is fully abstracted. See [HERE](https://developer.vialabs.io/general/package) for how to implement cross-chain contracts.

### Functionality

* **Automated Setup**: These contracts are pre-deployed by the system, so developers don't need to set them up manually.
* **Seamless Communication**: They ensure that messages and data are correctly routed and processed between different blockchains.

Gateway contracts work behind the scenes to manage cross-chain communication. Developers don't need to worry about interfacing with them; they are handled by the system to ensure everything runs smoothly.
