Transaction Fee System

There are two major updates to the transaction fee system.

1. The fee sharing feature, allowing DApp providers (instead of users) to pay the transaction fee, and
2. fee payment using Virtual Step, which is obtained through staking (there are different type of staking than IISS)

are both entering the stabilization phase

According to ICON Foundation https://medium.com/helloiconworld/3-icon-development-roadmap-update-mar-2019-a12956535d26 , these features will undergo a stabilization period starting in April and will likely be released during the second quarter.
