What Is the Role of a Liquidity Provider in a Perpetual Futures DEX?
A liquidity provider (LP) in a perpetual futures DEX often acts as the counterparty to all traders. Instead of trading against other individual traders, traders trade against the LP pool.
The LP's collateral is used to back the profits of winning traders, and they absorb the losses of losing traders, earning fees and sometimes funding payments for taking this counterparty risk.
