The "network fee" is the necessary transaction fee for sending SG to your wallet via a blockchain like Ethereum and Polygon. This fee will be charged to you when you make a transaction.
In the SocialGood App, you will pay this network fee when you use the following features.
*The network fee will be charged differently depending on if you are buying or withdrawing SG.
*This fee is charged by the network (Ethereum, Polygon), not by the SocialGood App. The network fee is calculated based on Etherscan and Polygonscan.
