# 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. For a list of contracts, please see the [Developer Documentation](http://developer.vialabs.io/). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.vialabs.io/via-omnichain-network/gateway-contracts.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
