Definition

A shared pot of two tokens that traders swap against.

Liquidity providers deposit both assets in a pair and receive LP tokens representing their share. Traders swap against the pool and pay a fee, which accrues to the providers.

Providing liquidity is not passive income without risk. If the two assets move apart in price, you can end up worse off than simply holding them.

In practice

Deposit ETH and USDC into a Uniswap pool and you earn a cut of every swap between them, proportional to your share.

What people get wrong

That your deposit sits there waiting for you. The pool rebalances continuously as people trade, so you withdraw a different mix than you put in: less of whatever rose, more of whatever fell. That is the mechanism, not a malfunction.

Common questions

How do liquidity providers make money?

A share of trading fees in proportion to their share of the pool, sometimes with token incentives on top. Whether that beats simply holding the two assets is a separate question and often the answer is no.

Can I lose money in a liquidity pool?

Yes, three ways: impermanent loss, a contract exploit, and one of the two tokens simply falling. Fees have to cover all three before it was worth doing.
