-Keep in mind that when using the local node setup, the Identity ABI needs to be manually copied into the `abi` folder. Additionally, ensure that the file is named `idsc_abi.json`. On the other hand, when working with a public network, consider publishing the ABI and dynamically loading it through an API.
