examples/chain/ibc/channel/query/4_ChannelClientState/example.go (4)

18-21: Ensure proper error handling instead of using panic.

Consider replacing panic(err) with a more graceful error handling mechanism, such as logging the error and exiting the program with a non-zero status code. This approach would be more robust in production-like environments.

---

23-31: Review the security implications of hardcoding sensitive information.

It's generally not secure to hardcode sensitive information such as user credentials ("12345678") and private keys ("5d386fbdbf11f1141010f81a46b40f94887367562bd33b452bbaa6ce1cd1381e") directly in the source code. Consider using environment variables or secure vault solutions to manage sensitive data.
