PulseX is a Hard Fork of Uniswap with PLSX Liquidity Provider incentivization. Its goal is to provide PulseChain users with the best possible trading experience & yield farm with a strong focus on incentivising ERC20 holders to bridge in and back the value of their free PRC20s.

The initial liquidity for PulseX comes from a bot called the "AMM ratio fixer bot". It harvests over around 99.9% of many coins liquidity from Uniswap, Suishiswap and other popular markets at launch, then recreates those pairs on PulseX and adds the liquidity it has harvested along with fresh PLS to make PulseX the vastly most liquid exchange on PulseChain. As users want the best deals for their trades, they tend to go where the liquidity is the largest. That creates volume. As liquidity providers make profit on volume, they are likely to deposit on the exchange with the most volume. It is hard for new competitors to overcome the critical mass of so much liquidity in one place.

Centralized liquidity also means the best deals for users because it results in low slippage. Meaning the price moves against them less when they swap. It also means that fewer arbitrage bots become rich equalizing the prices from different liquidity sources. It's more efficient.
