What is XTZ minimal balance?

XTZ is one of the assets that require an address to have a minimum balance. That amount is at least 0.27 XTZ.  

If you try to make a transaction without taking the minimum balance into account, the transaction will fail. In other words, if you have 0.7 XTZ and try to send out 0.7 XTZ, the transaction will not go through (since sending out 0.7 XTZ will put your balance below the required amount of 0.27 XTZ). 

For that reason, Atomic Wallet locks 0.27 XTZ on your balance so that the address could stay activated and ready to use. Thus,  0.27 XTZ is always excluded from your available XTZ balance. Further details can be found in the XTZ official documentation. 

There are three important things to consider with regard to XTZ minimal balance:

1. To activate your XTZ address in Atomic your first deposit should be equal to or more than 0.27 XTZ; 
2. You will not be able to send your funds out if your balance is below 0.27 XTZ. You may see that you have the balance, but when you want to send it, the available balance will be shown as 0. See the screenshots;

   

3. To be able to swap XTZ for another coin, the amount to swap should be higher than 0.27 XTZ. If your balance is below 0.27 XTZ, your XTZ available for swap will be 0.
