How does QuickSwap make money?

So, how exactly does QuickSwap generate revenue and sustain its operations? I understand it's a decentralized exchange platform on the Polygon network, but what specific mechanisms does it employ to monetize its services and ensure long-term sustainability? Are there any transaction fees or other forms of income generation that contribute to QuickSwap's profitability? And how does it ensure a balance between maintaining a user-friendly interface and maximizing its own financial gains?
