Liquidity Pool (DeFi Liquidity Pool)

What is a Liquidity Pool?

A liquidity pool is a smart contract that contains a reserve of two or more cryptocurrency tokens and is used to facilitate the exchange of cryptocurrencies on decentralized exchanges (DEX). The innovation of liquidity pools has laid the foundation for the decentralized finance (DeFi) industry.

Liquidity pools incentivize crypto holders to deposit their tokens in return for a part of trading fees. To participate, users need to hold their tokens in a cryptocurrency wallet. Typically, they deposit an equal dollar value of two tokens into a liquidity pool.

History of Liquidity Pools

In the early phases of DeFi, decentralized exchanges used traditional banking order books to match buyers with sellers.

This approach was problematic for several reasons:

• The order books required significant computing power to match buyers with sellers, and the process was slow.
• High gas fees made it difficult for smaller traders to participate in the market.
• Traditional order books are vulnerable to front-running. Users with faster connections could see and execute trades before users with slower connections.

In 2017, Bancor Network’s co-founders figured out a way to counteract these issues by executing trades against the liquidity of a pool of crowdsourced assets. This single change is credited with being responsible for DeFi’s rapid growth.

How Do Liquidity Pools Work?

DeFi liquidity pools enable cryptocurrency buyers and sellers to trade tokens on a DEX without needing a centralized order book or traditional market maker. Instead, the smart contract that controls the pool handles all the trading activity.

Automated market maker (AMM) algorithms in the contract determine the price of each token and adjust prices in real time depending on supply and demand. This ensures that the supply of each token in a pool is always in proportion to the other tokens in the pool.

If you are wondering how to participate in liquidity pools, you can simply add an equal dollar value of two tokens to the liquidity pool of your choice on any DEX. You will receive a share of the exchange’s trading fees. The value of trading fees earned is proportional to the amount of liquidity provided.

Liquidity Pool Tokens

Liquidity pool tokens (LPTs) are digital assets that investors receive when they deposit crypto assets into a liquidity pool. LPTs can be considered a receipt representing the investor’s share of the pool.

LPT ownership entitles the investor to a share of the transaction fees generated by the pool’s activity and any other potential rewards offered by the DeFi platform.

Investors can withdraw their liquidity from the pool at any time and redeem their LPTs in exchange for the original assets they deposited (along with any accrued fees or rewards).

Depending on the platform, LPTs may also be called pool tokens (PTs) or simply LPs.

What Can You Do With a Liquidity Pool Token?

Many investors simply hold on to their liquidity pool tokens to generate passive income. As users trade within the pool, they pay transaction fees, a portion of which is distributed to liquidity providers. Payment is proportionally based on the investor’s stake in the pool.

How Investors Use Liquidity Pools

Many DeFi platforms offer additional rewards to liquidity providers.

Investors who have high-risk appetites can use liquidity pools to participate in the following:

• Yield farming
• Staking
• Liquidity mining
• Platform governance
• Liquid staking

Liquidity Pools Explained: Types of Liquidity Pools

Liquidity pools can be categorized into the following:

The Importance of Liquidity Pools

Liquidity pools are important in blockchain borrow-lend protocols, yield farming, on-chain insurance, and gaming protocols.

Traditional finance (TradFi) has to pair a buyer with a seller before a transaction can be completed. In contrast, DeFi platforms can automatically execute a trade against the liquidity in the platform’s pool.

This is important because it means DeFi platforms don’t need to match the expected price of a transaction with the executed price. If the executed price of the trade is higher than the expected price, the buyer will receive fewer tokens than expected, and the seller will receive more tokens. This is called slippage.

To offset potential losses caused by slippage, the pool charges a small fee for each transaction and splits the fee between liquidity providers in a proportionate ratio to their share of the pool.

Total Value Locked

DeFi liquidity is typically expressed in terms of total value locked (TVL). TVL represents the total value of assets locked in a particular DeFi platform. Typically, this includes the amount of cryptocurrency locked in smart contracts and any other assets the platform has tokenized.

TVL is an important metric for DeFi protocols because it provides investors with an indication of a platform’s overall liquidity.

Platforms with higher TVL generally have more growth potential than those with lower TVL.

Liquidity Pools Pros and Cons

Let’s now learn about the pros and cons of liquidity pools:

Liquidity Pools Risks

Although liquid asset pools allow users to earn a yield on crypto that would otherwise be idle, using them to build passive income also comes with risks.

• Once assets have been added to a liquidity pool, they are controlled by a smart contract. If a malicious actor gains access to a smart contract that controls a liquidity pool, they may be able to steal all the funds in the pool.
• If smart contract developers permit themselves to change the rules governing the pool, there is always the risk that they will manipulate the contract for their own gain by altering the fee structure, the token ratio, or other key parameters of the pool.
• If the ratio of tokens in a liquidity pool becomes uneven due to significant price changes, the liquidity provider (LP) could face permanent as well as impermanent loss of their invested assets.

It’s essential for investors to be aware of the risks and take appropriate measures to protect their investments. This includes performing due diligence before investing in crypto liquidity pools.

Liquidity Pools Best Practices

Before investing in a DeFi pool, liquidity providers should thoroughly research the platform in question and the pool itself.

Best practices for ensuring a pool’s rules of liquidity are fair and predictable and that the liquidity providers’ interests are protected include:

Popular Liquidity Pools

Today, many decentralized platforms use liquid asset pools to trade digital assets in an automated and permissionless way. The meaning of liquidity pools in DeFi is significant, as they provide the necessary liquidity for the ecosystem to function efficiently and reduce reliance on traditional financial intermediaries.

Popular platforms that center their operations on liquidity pools include:

The Bottom Line

Liquidity pools are one of the most important innovations of decentralized finance. When Uniswap introduced its liquidity-pool-powered AMM protocol in 2018, it marked the creation of a product that embodied the core values of cryptocurrencies –  decentralization and permissionlessness.
