Non-Fungible Liquidity Positions

In Uniswap V3, liquidity positions are represented as non-fungible tokens, or NFTs, because each position is customized by the user. Since providers choose their own price ranges, no two positions are identical in terms of their risk exposure and fee-earning potential.

These ERC-721 tokens encapsulate the specific range, the amount of assets provided, and the accumulated fees for that unique position. This differs from previous versions where liquidity was fungible, meaning any share of a pool was interchangeable with another.

The use of NFTs allows for more complex financial instruments to be built on top of liquidity positions, such as automated management vaults or collateralized debt positions. It marks a transition from simple pooled assets to individualized, programmable financial assets.
