# Cronos Configuration

After creating **BP\_DefiWalletCore**, we should configure the Network Configuration, so that when we spawn the actor, we could get the same network settings.

* Double click **BP\_DefiWalletCore** in **Content Browser**, and open the Blueprint Editor
* In **Cronos Play Unreal** section of **Details** tab, input the RPC and Chain ID settings, for example like below:
  * `My Cronos Rpc`:
    * **\[Testnet]** <https://evm-dev-t3.cronos.org>; or
    * **\[Mainnet]** <https://evm-dev.cronos.org>.
  * `My Cronos Chain ID`:
    * **\[Testnet]** 338; or
    * **\[Mainnet]** 25
