In the cryptocurrency market, liquidity fundamentally refers to how simple it is to exchange one coin for another (or government-issued fiat currencies). Order books, similar to those seen on a stock market, are one method to achieve liquidity. Here, buyers and sellers of assets enter orders, detailing the price and quantity they are willing to pay for the asset they wish to acquire or sell. The asset’s price is then determined by an exchange, such as a centralized exchange, matching buy and sell orders.
A market maker, an agent who is always prepared to purchase and sell specific assets, can be used as an alternate method of supplying liquidity to the market. For example, decentralized finance (DeFi) has centralized exchanges that serve as market makers, like Binance (a company). However, a decentralized counterpart that replaces a centralized market maker is one of the intriguing features of DeFi. For instance, tokens can be swapped using a decentralized exchange (DEX) like Uniswap rather than a centralized exchange.
Furthermore, to establish a liquid DeFi system, liquidity pools are important. In order to have enough funds in a liquidity pool, liquidity providers (LPs) are needed, who put a large sum of money into the pool. Because liquidity providers help the protocol provide liquidity, they receive a reward in return. This reward is generated by the transaction fees, which are paid by the pool’s users.
