Keep up Gas Balance
To cover these fees Flex stores an amount of native EVER tokens as your Gas balance.
This balance will gradually be spent on trading and deploying new internal wallets whenever you acquire an asset you did not previously own (~10 EVERs per new asset wallet).
Its currently available value is always displayed in the top right corner of the Flex window.
Note: The balance displays your total gas on Flex. Of this amount 20 EVERs are reserved on your Flex Client contract for various system actions. The rest is used to pay for gas on the exchange.
If the balance turns red, it needs to be topped up.
To top it up, click on the displayed Gas balance.
