The liquidity pool is challenging the inadequate liquidity problems of the order book model. For that reason, exchanges won’t depend on bidders and takers to fill the order book. Also, the traditional exchanges who often manipulate trades to lure investors won’t bother doing that again. Consequently, let’s know what necessitated liquidity pools.
Before now, the traditional markets, including Cryptocurrency, stock, and forex suffered inadequate liquidity. For every trade, a buyer will have to wait for a seller to set prices. Until both parties agree on a price, there will be no trade.
However, trades may not happen or sometimes take a longer time. In solving the bureaucratic nature of the order book, seeking a way to provide liquidity becomes necessary because it hinders investment while deterring promising projects.
Meanwhile, the order book model is not limited to centralized exchanges as decentralized exchanges have the same fate at its early stage. Consequently, liquidity pools – through automated smart contracts is filling the gap.
However, it will be interesting that you have a basic understanding of liquidity and why they are needed.
Uniswap is a decentralized ERC-20 token exchange that supports 50% Ethereum contracts, and 50% of other target assets (ERC-20 tokens) contracts. It allows you to exchange ETH for any other ERC-20 token in a decentralized manner.
It operates an open-source exchange where you can create a new exchange pair in a new liquidity pool for any token and at no listing cost. However, the platform charges swappers 0.3% swapping fee and are shared with the liquidity providers. You may find the token list here or also able to create a new one.
Similar to other liquidity pools providers, you are simply depositing crypto to receive a Uniswap token when you are supplying liquidity. For instance, when you deposit DAI, you will receive an equivalent amount of Uniwap token. It comprises several liquidity pools as follows: yDAI+yUSDC+yUSDT+yTUSD, AD, LGO-WETH, WETH-AMPL, and many other pools.
