governance_chainConfig

The chainConfig property provides the latest chain configuration. This is equivalent to chainConfigAt() with an empty parameter.

NOTE: In versions earlier than Klaytn v1.10.0, this API returned the initial chain configuration. However, due to its confusing name, it is updated since Klaytn v1.10.0. To query the initial chain configuration, use chainConfigAt(0) instead.
