What Is the Role of a “Liquidity Provider” and How Does It Differ from a Market Maker?

A liquidity provider (LP) supplies assets to a trading pool, typically in a decentralized exchange (DEX), to enable others to trade. They earn fees from the trades that occur in the pool.

A market maker (MM) actively quotes bid and ask prices on an exchange, adjusting them rapidly to profit from the spread and manage inventory risk. While both contribute to market liquidity, the LP is passive, earning fees based on pool activity, whereas the MM is an active, professional trader managing risk and seeking profit from the bid-ask difference.
