What are Crypto Liquidity Pools?

As of mid-October 2022, approximately US$28 billion of crypto assets were locked up in liquidity pools across all decentralised finance apps (dApps). But what is a liquidity pool? Crypto liquidity pools help decentralised exchanges (DEXs) efficiently facilitate trades for buyers and sellers of cryptocurrency assets.

This article looks at cryptocurrency liquidity pools and how they work. It also explores the pros and cons of crypto liquidity pools and explains how crypto liquidity pools can help users make profits.

How do Crypto Liquidity Pools Work?

A crypto liquidity pool is a bucket of crypto assets used to facilitate trades on decentralised exchanges. In centralised crypto exchanges, when an investor buys or sells their assets, usually a centralised market maker matches buyers with sellers to execute the trade.

On decentralised exchanges, however, trading liquidity is sourced from a pool of assets that liquidity providers contribute to. When users wish to trade their crypto assets, an automated market maker (AMM) sources liquidity from the pool to execute the trade.

Liquidity pools collect and hold assets from LPs (liquidity providers), who deposit assets into the pool. In return for taking on the risks of investing their capital, LPs receive a token that represents their share of the liquidity pool. The token entitles LPs to a proportion of the transaction fees generated by the AMM from users trading assets through the pool, through decentralised exchanges.

Algorithms determine the fair market values for tokens in a pool. The algorithms account for the impact of supply and demand on tokens in the pool, as users exchange one asset for another through it.

What is the Purpose of a Liquidity Pool?

A liquidity pool is a group of digital assets locked in a smart contract that provide essential liquidity to decentralised exchanges. Liquidity pools leverage the power of automated technologies and algorithms to facilitate instant exchanges of value. Instead of depending on the availability of sellers and buyers for a given trade, a liquidity pool provides a steady source of assets for instant trades.

How do Crypto Liquidity Pools Make Money?

Cryptocurrency liquidity pools make money by charging transaction fees on any trades made on the exchange. Fees are applied by the smart contract and are immutable.

For example, suppose a decentralised exchange charges 1% for every transaction made on the platform via a smart contract. Whenever a person sells the equivalent of US$100 worth of assets, US$1 is kept by the pool in fees. Part of the transaction fee is then redistributed proportionally to every LP token holder.

Are Crypto Liquidity Pools Safe?

Crypto liquidity pools provide a way to deploy or hold assets in DeFi and earn a return. However, if you provide liquidity, your assets could lose value during price fluctuations. This loss is referred to as impermanent loss.

Advantages of Liquidity Pools

A few benefits of using crypto liquidity pools to offer liquidity on cryptocurrency exchanges include:

  • Publicly viewed smart contracts: Smart contract code that determines the rules for crypto liquidity pools can be publicly audited, providing complete transparency.

  • Decentralisation: Buyers and sellers can carry out transactions without a third-party intermediary, such as a centralised exchange, which could intervene to and stop/freeze transaction activity.

  • Automation of trades: Liquidity pools match trades using smart contracts and algorithms. This technology ensures that users are treated equally on the exchange.

  • Opportunities to earn: Crypto liquidity pools provide various earning opportunities for liquidity providers. Liquidity providers can expect returns depending on the variables written into the smart contract, such as assets, structure of the pool, and more.

So long as there are liquidity providers, you’ll always be able to place a trade regardless of the price.

Disadvantages of Liquidity Pools

When choosing a liquidity pool to invest in, it is important to look out for risks, including:

  • Fraud: Questionable projects may offer extra privileges to developers, such as an admin key. Such keys may allow developers to control funds in the pool and expose investors to rug-pull scams. When investing, it is important to do your research on the smart contract to find any hidden privileges.

  • Honeypots: This is a metaphor that refers to something that is designed to attract someone and trap them, resulting in the draining of their crypto.

  • Impermanent loss: Impermanent loss is a common risk investors face when supplying funds to a liquidity pool. It occurs when the value of deposited assets change because of price fluctuations, which can leave LPs with large opportunity costs.

  • Smart contract bugs: A smart contract manages the funds in a liquidity pool. A poorly designed smart contract may be susceptible to bugs that cause token holders to lose money.

  • Illiquidity: liquidity dries up, making it impossible to trade an asset.

Liquidity Pools Versus Order Books

Liquidity pools and order books provide different mechanisms to process user transactions. In an order book, buyers and sellers record the number of assets they’re willing to buy and sell at a desired price point. Order books are commonly used on large centralised crypto exchanges, whereas a liquidity pool may not be needed because of an abundance of buyers and sellers. Problems may arise, though, if no one is willing to buy or sell an asset.

Liquidity pools in theory maintain a constant pool of assets through which users can transact. This is made possible by liquidity providers that deposit their assets, which are locked up in the pool. An important feature of a liquidity pool is that traders get consistent pricing at any given time. Additionally, traders can benefit from relative price stability with large liquidity pools.

Invest, Trade, and Earn with Liquidity Pools

Obtaining liquidity in cryptocurrency can sometimes be a challenge for crypto exchanges. With liquidity pools, smaller decentralised exchanges can facilitate trades. Users providing liquidity can also earn passive income.

Liquidity pools are at the core of the crypto trading markets. Understanding how they work and the impacts they can have on your trading, can help shape a more informed and rounded investment strategy.
