Liquidity Provider (LP)
A person or entity that deposits tokens into a liquidity pool on a decentralized exchange, earning trading fees in return.
Liquidity providers make decentralized exchanges possible. Without LPs depositing tokens, there would be nothing for traders to swap against. In return for providing this service, LPs earn a cut of every trade that uses their pool.
To become an LP, you deposit a pair of tokens (like USDC and ETH) in equal value. The pool uses these tokens to facilitate swaps. Every time someone trades using your pool, you earn a proportional share of the trading fee (typically 0.05-0.3%).
The main risk is impermanent loss. If the price ratio of your deposited tokens changes, you could end up with less value than if you'd just held. For stablecoin-only pools (USDC/USDT), this risk is minimal, making them popular for conservative yield seekers.
