Uni V2 pools

Like concentrated liquidity pools, Uni V2 pools maintain Uniswap's source code and interface, allowing direct interaction with pairs or routers in familiar ways.

Uniswap V2 Contract Overview

LP Staking

• When LP is unstaked, fees accumulate to the LP through increasing LP value, just like in Uniswap V2.

• When staked, fees accumulate as bribes and LPs receive emissions, in which case the value of LP value increase is adjusted through the reduction of staked LP token amount in the vault.

• Therefore, protocols that receive V2 LP tokens from users for staking should be mindful of the deflationary case and carefully record the deposited LP amount in their mapping to avoid reuse. If using without staking, this is irrelevant as there are no changes to the LP token amount.
