'Poloniex reviews coin submissions and makes decisions based on several criteria. Where applicable, a coin must have:
A block explorer
A website
A unique genesis block
A compiled wallet

We also conduct a thorough code review before a coin is added on our exchange. In addition, we like to see evidence of the developers' dedication to the project, community interest, and above all else, innovation. If you feel your coin is truly innovative, we want to hear about it. Poloniex never requests payments to list coins.'
