The official eWAY Magnento 2 extension is now available from the Magento 2 marketplace! It has support for securely accepting payments with the eWAY gateway, plus for customers can save the card details as eWAY tokens and a bunch of other features.
As eWay payment is unavailable in default Magento 2 community version, you can check and install our Magento 2 eWay Payments extension which allows accepting secure payments from the customers.
