The process of providing liquidity to the exchange is called market making, and the entities that provide this service are called market makers. To achieve a fluid trading system, centralized exchanges rely on professional https://www.xcritical.com/ traders or financial institutions to provide liquidity for trading pairs. These entities create multiple bid-ask orders to match the orders of retail traders. With this, the exchange can ensure that counterparties are always available for all trades. In this system, the liquidity providers take up the role of market makers. In other words, market makers facilitate the processes required to provide liquidity for trading pairs.

Liquidity Pools and Liquidity Providers

This article explains what automated market makers are, how they work, and why they are critical to the DeFi ecosystem. The beauty of DeFi is that when conducting a token swap on a decentralized crypto exchange (DEX), users never need a constant product market maker specific counterparty or intermediary. They enable essentially anyone to create markets seamlessly and efficiently.

This is where market supply and demand act to change the initial exchange price of BTC, which was equal to 25,000 USDT. Be careful when depositing funds into an AMM, and make sure you understand the implications of impermanent loss. If you’d like to get an advanced overview of impermanent loss, read Pintail’s article about it.

Liquidity pools can be optimized for different purposes, and are proving to be an important instrument in the DeFi ecosystem. In summary, automated market makers (AMMs) and decentralized exchanges (DEXs) provide a permissionless, non-custodial alternative to centralized trading platforms. Replacing order books with liquidity pools, AMMs enable liquidity providers to earn a passive income with crypto and make fast token swaps without intermediaries. An automated market maker (AMM) is an autonomous protocol that decentralized crypto exchanges (DEXs) use to facilitate crypto trades on a blockchain.

Different Automated Market Maker (AMM) Models

These liquidity providers ensure that there are always counterparties to trade with by providing bid-ask orders that would match the orders of traders. The process involved in providing liquidity is what we call market making, and those entities that deliver liquidity are market makers. To ensure that assets are readily available at any time, liquidity providers deposit funds into liquidity pools. These funds often come in pairs or “token pairs”, meaning that an LP would provide an equal value of two different asset types to a liquidity pool. Though this is not always the case, this is how many popular DEXs and AMMs work, including the number one DEX on Ethereum, Uniswap. Impermanent loss is the difference in value over time between depositing tokens in an AMM versus simply holding those tokens in a wallet.

Problems of First-Generation AMM Models

LP tokens use a special type of currency code in the 160-bit hexadecimal “non-standard” format. The remainder of the code is a SHA-512 hash, truncated to the first 152 bits, of the two assets’ currency codes and their issuers. The AMM is designed so that an AMM’s asset pool is empty if and only if the AMM has no outstanding LP tokens. This situation can only occur as the result of an AMMWithdraw transaction; when it does, the AMM is automatically deleted.

Also, DEXs replace order matching systems and order books with autonomous protocols called AMMs. These protocols use smart contracts – self-executing computer programs – to define the price of digital assets and provide liquidity. In essence, users are not technically trading against counterparties – instead, they are trading against the liquidity locked inside smart contracts. Impermanent loss is the primary and the most common risk experienced by liquidity providers in automated market makers. Impermanent loss is the decrease in token value that users experience by depositing tokens in an AMM versus merely holding them in a wallet over the same time. In other words, these market makers constantly offer to buy and sell an asset at multiple prices so that users will always have someone to trade against.

In traditional markets such as stocks, bonds, gold, and crypto, there are usually at least three parties involved. In the case of centralized crypto exchanges, the order book matches buyers and sellers to execute trades using a centralized order book. Buyers can decide how much they want to pay for an asset, and sellers can set a price for the sale of assets. With over 2.2 million users, PancakeSwap is the largest AMM on Binance Smart Chain. Its focus on low fees and fast transactions has attracted many traders to the platform. The platform offers a range of liquidity pools for users to earn rewards in CAKE tokens.

By doing this, you will have managed to maximize your earnings by capitalizing on the composability, or interoperability, of decentralized finance (DeFi) protocols. Note, however, that you will need to redeem the liquidity provider token to withdraw your funds from the initial liquidity pool. When the flow of funds between the two assets in a pool is relatively active and balanced, the fees provide a source of passive income for liquidity providers.

• Instead, they interact with smart contracts to buy, sell, or trade assets.
• But, LPs can minimize this risk by using token pairs of a similar value and market cap.

• Secondly, Shared Pools allow anybody to provide liquidity and use the Balancer Pool Token (BPT) to track the ownership of the pool.
• Some of the well-known AMMs include Uniswap, SushiSwap, PancakeSwap, and Balancer.
• Furthermore, the use of automated market makers eliminates the need for order books, making trading more efficient and less prone to manipulation.

However, decentralized exchanges (DEXs) and automated market makers (AMMs) are non-custodial. Not only does this mean that users have control of their assets, but it also means that assets cannot be seized, frozen, or restricted in the same way that they can be with CEXs. Meanwhile, market makers on order book exchanges can control exactly the price points at which they want to buy and sell tokens. This leads to very high capital efficiency, but with the trade-off of requiring active participation and oversight of liquidity provisioning. The constant, represented by “k” means there is a constant balance of assets that determines the price of tokens in a liquidity pool. For example, if an AMM has ether (ETH) and bitcoin (BTC), two volatile assets, every time ETH is bought, the price of ETH goes up as there is less ETH in the pool than before the purchase.

However, Smart Pools can readjust the weighting and balances of assets, as well as trading fees. Many of first-generation AMMs are limited by impermanent loss and low capital efficiency, which impacts both liquidity providers and traders. You can use them in many types of payment, or trade them in the decentralized exchange. Similarly, you can only send assets to the AMM’s pool through the AMMDeposit transaction type. SushiSwap is a popular fork of Uniswap which offers similar features such as trading, staking, and liquidity pools. However, it differentiates itself by having a multi-chain approach with support for over 16 blockchain networks.

At their essence, AMMs are decentralized protocols that enable digital assets to be traded automatically and without the need for traditional market makers. By using liquidity pools instead of order books, AMMs facilitate trading by ensuring there is always a counterparty ready to fill a trade. This not only streamlines the trading process but also enhances liquidity, making markets more efficient and accessible.

AMMs, on the other hand, utilize mathematical formulas to determine the price of assets and execute trades, which can reduce trading costs and the spread between buy and sell prices. With that said, impermanent loss isn’t a great way to name this phenomenon. “Impermanence” assumes that if the assets revert to the prices where they were originally deposited, the losses are mitigated. However, if you withdraw your funds at a different price ratio than when you deposited them, the losses are very much permanent. In some cases, the trading fees might mitigate the losses, but it’s still important to consider the risks. One of the most widely used automated market maker platforms is Uniswap.

For a detailed explanation of the constant product AMM formula and the economics of AMMs in general, see Kris Machowski’s Introduction to Automated Market Makers. As AMMs operate without human interaction, there is a possibility of bugs and glitches occurring with smart contracts. These can lead to issues such as incorrect pricing or failed transactions. While developers constantly work to identify and fix these issues, they can still occur, causing inconvenience and potential losses for users. Liquidity pools allow users to make transactions directly on the blockchain and seamlessly switch between tokens in a completely decentralized and non-custodial manner.
