ShapeShift.io supports a number of coins. To find a full list of the supported coins available, please go to beta.shapeshift.com/assets and click the + button. From there you will see all of the coins/tokens available. ShapeShift has integrated with 0x and THORChain so many of our cryptoassets are dependent on what they support.
If you would like to suggest additional coins for us to support, please do so here: https://shapeshift-io.hellonext.co/
