Users can trade in different cryptocurrencies with liquidity pools instead of using external exchanges. A smart contract is a self-executing software based on the agreements between buyers and sellers. It refers to a pool of tokens locked in that contract and are referred to as a liquidity pool. The pool makes it possible for users to trade cryptocurrencies by offering them liquidity.
The simplicity with which a token may be exchanged for another is referred to as liquidity. Given the wide variety of cryptocurrencies available today, it is crucial to the decentralized finance (DeFi) ecosystem.
By using the automated market maker (AMM) method, liquidity pools serve as the framework for DEX. The AMM is a mechanism where investors, or in this case, “liquidity providers” (LPs), put equal amounts of cryptocurrencies and stable coins into the pool—for instance, ETH/USDC. In this manner, users may exchange one stablecoin for another by swapping USDC for Ether at the same value (USD Coins). LPs offer a service by providing DEX buyers and sellers with tokens that can be readily traded on the same blockchain.
The Role of DeFi Liquidity Pools
Smart contracts called liquidity pools are used to store locked crypto tokens that platform members have contributed. They operate independently and don’t require middlemen to function. They are assisted by automated market makers (AMMs), which use mathematical algorithms to help keep the balance in liquidity pools.
On a decentralized exchange, users rely on tokens from the A/B liquidity pool given by other users when they sell token A to acquire token B. As a result of their purchases, there will be less B tokens available in the pool, increasing the value of B. It’s just basic supply and demand economics.
In the decentralized finance (DeFi) ecosystem, cryptocurrency liquidity pools are crucial, especially for decentralized exchanges (DEXs). Users can pool their assets in DEX’s smart contracts to create liquidity pools, which offer asset liquidity for traders to trade across currencies. The DeFi ecosystem benefits from liquidity pools, which provide it with the liquidity, speed, and convenience it needs.
Prior to the advent of automated market makers (AMMs), Ethereum-based DEXs struggled to find liquidity in the cryptocurrency market. There were few buyers and sellers at the time. DEXs were a new technology with a confusing interface. Thus, it was challenging to locate enough individuals eager to trade often.
Without the need for intermediaries, AMMs create liquidity pools and provide liquidity providers with incentives to contribute assets to these pools. This fixes the issue of low liquidity. Trading on decentralized exchanges gets simpler when a pool of assets and liquidity increases.
Are Liquidity Pools Important?
High slippage results from low liquidity or the significant discrepancy between the predicted price of a token trade and the price at which it is performed. Because there are so few tokens locked up in pools due to low liquidity, token movements as a swap or any other transaction resulting in higher imbalances. On the other hand, there won’t be much slippage for traders when the pool is really liquid.
High slippage, however, is not the worst-case scenario. Users will be trapped with tokens they can’t sell if there is not enough liquidity for a certain trading pair (let’s say ETH to COMP) on all protocols. Rug pulls essentially cause this, although it can also occur spontaneously.
Any seasoned trader in either traditional or cryptocurrency markets can inform you of the risks of joining a market with minimal liquidity. Slippage is a worry when trying to enter or leave any deal, whether it be with a low-cap cryptocurrency or penny stock.
Slippage is the discrepancy between a trade’s anticipated price and the price at which it is actually performed. Slippage can also happen when a large order is filled, but there isn’t enough volume at the chosen price to sustain the bid-ask spread. It happens most frequently during times of increased volatility.
In a conventional order book model, the market order price employed during periods of high volatility or low volume is decided by the bid-ask spread of the order book for a certain trading pair. This indicates that it is situated halfway between the price at which sellers are willing to sell the item and the price at which buyers are prepared to acquire it.
Nevertheless, poor liquidity might result in increased slippage and, depending on the bid-ask gap for the asset at any particular time, the executed trading price may be significantly higher than the initial market order price.
By offering users incentives to supply cryptocurrency liquidity in exchange for a cut of trading commissions, liquidity pools seek to address the issue of illiquid markets. Trading using buyer-and-seller matching is not necessary when using liquidity pool protocols. This indicates that users may easily trade their assets and tokens utilizing the liquidity offered by users and conducted through smart contracts.
How Does DeFi Liquidity Pools Earn?
LPs earn interest in the form of trading fees on transactions made within the pool in return for contributing tokens. Another name for this is liquidity mining. Uniswap, a DeFi firm, charges a flat transaction fee of 0.3 percent on their platform.
Through trading in liquidity pools over time, LPs can earn anywhere between 2 and 50 percent yearly. To increase their profits, some LPs even transfer between various liquidity pools. This practice is referred to as “yield farming,” where “yield” refers to the interest that traders make from staking digital assets.
Challenges Faced by Liquidity Pools
A transient loss of tokens from a liquidity pool is referred as an impermanent loss. A multitude of things, including price fluctuation or hacking, might cause this. For instance, in the case of a BTC/USDT liquidity pool, LPs receive less value back if the price of Bitcoin decreases by 20%. This is due to the fact that they have lost 20% on every stablecoin placed into that pool.
As a result, there is a temporary loss because the value of these tokens is no longer equivalent to what it was initially. Problems with smart contracts, like hacking or flaws, provide another difficulty. Also, given that the system is decentralized, there is no legal redress if theft happens.
