Overview

Package msgfee allows to define and charge an additional fee per transaction type.

With this extension it is possible to declare a fee for each transaction message type. For each message path a coin value can be declared. After successful processing of a transaction the result required fee value is increased by the declared coin value.

This extension does not know of supported (installed) message paths and therefore cannot validate for their existence. Make sure that when registering a new message fee the path is set correctly.
