name: ChainProperties

description: Wraps the properties retrieved from the chain via the system.properties RPC call. It extends the standard JS Map with de-facto values exposed as getters. While it implements a Codec, it is limited in that it can only be used with input objects via RPC, i.e. no hex decoding. Unlike a struct, this wrasp a JSON object with unknown keys and any values for those
