DVIP
From CryptoWiki
From DeFi Rate:
"IDEX currently uses two native tokens, AURA and DVIP, to further incentivize usage of the platform. Simply put, AURA is staked to earn a percentage of all transaction fees on the network. AURA can be used to purchase DVIP tokens (1 DVIP = 50,000 AURA) which are used to purchase IDEX memberships, granting users discounts on trading fees on IDEX transactions. DVIP memberships will last until 2020, granting users either free trades and no AURA rewards, 2x Market Making rewards and full trade fees or some combination of both."
