# LiquidityPosition

**LiquidityPosition** represents an individual liquidity provider’s stake in a TradingPool. When a user supplies NFTs and tokens to a pool, they receive LP tokens tracking their share.

**Key Fields**:

* `pool_id`: Links the position to a specific TradingPool.
* `lp_tokens`: The user’s balance of LP tokens.
* `nft_contributed` / `tokens_contributed`: Tracks how much the user initially deposited.
* `fees_earned`: Amount of fees this position has accrued over time.

**Role**:

* Allows users to retrieve their proportionate share of the pool’s reserves at any time.
* Incentivizes providing liquidity by entitling providers to a share of trading fees.
