**Enabling a Channel on Other Chains with Channel Alias: A Guide**

To expand your channel's reach and send notifications on multiple chains, beyond Ethereum, you'll need to understand the concept of "Channel Alias." This guide will walk you through the significance of Channel Alias and how to set it up for a preferred chain, using an example with the Polygon chain.

**Understanding Channel Alias and Its Significance:** The NeoCast Protocol is designed to allow your channel to send notifications on various chains, not just Ethereum. To achieve this, Channel Alias plays a crucial role. It enables your channel to have a presence on other chains and ensures that your notifications are delivered effectively.

**Setting Up Channel Alias:** To set up a Channel Alias for your channel on a preferred chain, follow these two simple steps:

**Step 1: Selecting the Chain and Providing Alias Address:**

* During the channel creation process, you'll have the option to select the chain on which you want to send notifications. This could be Ethereum, Polygon, BSC, or another supported chain.
* At this stage, you'll need to provide the appropriate Alias Address for your channel on the selected chain.

**Step 2: Verification of the Alias Address:**

* After providing the Alias Address during channel creation, the verification process begins.
* The Alias Address you specify must be your own and will be verified as part of the channel creation process. This ensures that you have control over the address used for channel communication.
* Verification typically involves confirming ownership or control of the Alias Address on the selected chain.

**Example: Setting Up a Channel Alias on the Polygon Chain:** Let's use the Polygon chain as an example to illustrate the process:

1. During channel creation, select the Polygon chain as the target network for sending notifications.
2. Provide an Alias Address that represents your Ethereum channel on the Polygon chain.
3. The Alias Address must be a Polygon-compatible address and should be under your control.
4. The Neo Cast Protocol will then initiate the verification process, which may involve confirming ownership of the Alias Address on the Polygon chain.

Once the Alias Address is successfully verified, your channel is set up to send notifications on the Polygon chain, expanding your reach to users on that specific blockchain.

In summary, Channel Alias is a vital feature that allows your channel to send notifications on various chains. Setting it up involves selecting the chain, providing the Alias Address, and undergoing a verification process to ensure control over the Alias Address. This enables your channel to effectively communicate with users on multiple blockchain networks.
