# Uniswap v2 and v3: full-range versus concentrated liquidity

Uniswap v2 pools place liquidity across the full constant-product price range. Uniswap v3 lets liquidity providers choose price ranges, concentrating capital where it can trade. That changes inventory, position management and fee opportunities; it does not guarantee higher net returns for every provider.

## Key facts

- **V2:** Liquidity follows the full-range constant-product reserve relationship. ([Uniswap v2 whitepaper](https://app.uniswap.org/whitepaper.pdf))
- **V3:** Positions specify bounded price ranges and can become inactive outside them. ([Uniswap v3 whitepaper](https://app.uniswap.org/whitepaper-v3.pdf))
- **Oracle:** The versions use different cumulative-price accounting methods. ([Uniswap v2 whitepaper](https://app.uniswap.org/whitepaper.pdf); [Uniswap v3 whitepaper](https://app.uniswap.org/whitepaper-v3.pdf))

## Choose where the position offers liquidity

A v3 provider can put capital in a narrow interval around a price. While active, that capital can support more liquidity per deposited amount than the same capital spread across a full range.

If price exits the interval, the position becomes concentrated in one asset and stops providing active liquidity there. Repositioning changes exposure and can incur costs.

## More concentrated fees come with different exposure

V2 and v3 have different fee and position-accounting arrangements. V3 positions can differ by range and fee tier, so two providers in the same asset pair need not earn the same return.

Compare fees with inventory changes, gas and rebalancing costs. Gross fee earnings do not equal profit relative to simply holding the original assets.

## Do not extend one version’s behavior to every pool

The cited white papers describe v2 and v3 designs. Later versions and integrations can add other mechanisms. A brand name or token pair does not identify the exact pool behavior.

Use the pool address, deployment version, fee configuration and position range when reproducing a calculation.

## Questions

### Does v3 remove impermanent loss?

No. Concentrated liquidity changes where and how inventory changes occur. It does not eliminate divergence from the value of holding the original assets.
