ZRX (0X) Listed on Polo last night?

Anyone know anything about this coin just listed on Polo? Today is the first i've heard of it.
The site says it's an Ethereum smart contract/trading protocol?

I bought some @.00012500 BTC after selling some BCH (just in case) and it seems to be going up.
Anyone else know anything about it?
It's already #22 on coinmarketcap
