Paradex co-founder Fiddy: Zero fees do not mean zero income, but a reconstruction of the exchange's business model

In a technology and cryptocurrency podcast, Fiddy, co-founder of the high-performance decentralized exchange Paradex, stated that DEX fees should no longer be proportional to trading volume; instead, fees should depend on the positive or negative impact brought to the liquidity pool. Order flow similar to Robinhood is completed within a relatively closed small system, resembling a web2 model. However, in the DeFi space, there is no need for such a permissioned "order flow"; rather, it is more about directly "permitting" trading orders through technical means, which also requires DEX products to expand into new business models beyond just transaction fees.
