How Does the ‘Fee Structure’ Differ between a Centralized Exchange (CEX) and a Decentralized Exchange (DEX) AMM?
CEX fee structures typically use a maker-taker model, where 'makers' (providing liquidity) pay lower or zero fees, or even receive rebates, while 'takers' (removing liquidity) pay higher fees. DEX AMMs, conversely, charge a flat percentage fee on all trades.
This fee is then distributed proportionally to the liquidity providers (LPs) in the pool, which is the core incentive mechanism for the AMM model.
