Pool is a service that allows users to provide liquidity to NEOPIN by depositing a pair of tokens into a liquidity pool developed based on the Automated Market Maker ([**AMM**](https://docs.neopin.io/earn-with-neopin/swap/automated-market-maker)) model, and rewards users in return. Users may earn additional NPT rewards proportional to the amount deposited in the pool and a certain share of the swap fees generated on NEOPIN.

**▶ Impermanent Loss**\
Impermanent loss occurs when the price of assets in a pool changes. For more details, please check [**here**](https://docs.neopin.io/earn-with-neopin/pool/impermanent-loss).
