DinoSwap, launching on Polygon, is a pass-chain infrastructure platform that builds liquidity for layer-one blockchains, AMMs and partnering initiatives. The reason of the DINO token is to facilitate and sell go chain DeFi liquidity. DINO tokens are a reward for liquidity vendors in available farms. DINO itself may be staked/burned in pools to earn one-of-a-kind tokens as rewards.
