Understanding Automated Market Makers AMM in DeFi: A Comprehensive Guide

Uniswap runs on the Ethereum network and ETH (\(X\)) is the native settlement token. However, there are a number of ERC-20 tokens that can be traded on the network, and one https://www.xcritical.com/ can swap between any two ERC-20 tokens \(Y\) and \(Z\) on Uniswap. How exactly this exchange is facilitated varies between v1 and v2 of Uniswap.

Challenges and Limitations of AMMs

Despite this, CSMMs are rarely used as a standalone market maker, due to liquidity concerns about handling large trades. Orca is a rising star in the world of DEXes, focused specifically on the Solana blockchain. With its emphasis on user-friendliness and quick transactions at low fees, it has quickly gained popularity amm in crypto among traders. AMMs operate on distributed ledgers or blockchains, removing the need for a central authority or intermediary.

• An Automated Market Maker (AMM) is basically the decentralized equivalent of a traditional cryptocurrency exchange’s centralized order book.
• Here, the geometric mean of all assets in the liquidity pool forms the constant K, allowing each to be priced according to liquidity conditions as with a CPMM.
• 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.
• We only assigned dollar values in our example to create an equal value ratio.
• In contrast, three-point arbitrage (or triangular arbitrage) focuses on the internal consistency in the prices offered within a single market and requires three price quotes for its implementation.

This enables permissionless trading, where anyone with an internet connection can participate in buying and selling crypto assets. This paper presented a unified framework based on the neoclassical black-box to characterize different types of AMMs that are currently popular as DEXs. One of the main advantages of such a framework is that it provides a set of simple tools that can be used to visualize the geometry of a given AMM. This makes it easy to see, for example, why the price remains unchanged when both reserves are doubled. It also allows for a simple way to check when manipulating a given exchange function makes a significant difference and when it does not. Other properties, such as Euler’s theorem provide a convenient method to value a liquidity pool in an AMM.

How do Constant Sum Market Makers (CSMM) work?

Hybrid Constant Function Market Makers (CFMMs) combine elements of different AMM models to optimize for both liquidity provision and price stability, aiming to reduce issues like impermanent loss. The pricing mechanism in AMMs, while usually efficient, in some cases may lead to issues like impermanent loss for liquidity providers, particularly in highly volatile market conditions. Users, known as Liquidity Providers (LPs), contribute their assets to these pools and, in return, receive LP tokens. These tokens represent their share of the pool and can be redeemed later for their portion of the pool plus any accrued fees. WhiteSwap’s approach to decentralized trading and liquidity provision illustrates the innovative capabilities of AMMs in the DeFi space. Its governance model, incentivization strategies, and focus on cross-blockchain operability highlight the evolving nature of AMMs in catering to diverse needs within the cryptocurrency ecosystem.

While developers constantly work to identify and fix these issues, they can still occur, causing inconvenience and potential losses for users. AMMs enable trading of a wide range of crypto assets that may not be available on traditional exchanges. These platforms support various tokens, including newly launched or less popular ones. In a CPMM such as Uniswap, the product of the quantity of two tokens in a liquidity pool is a constant. The example examined here replicates and extends the one developed in the original Uniswap-v1 whitepaper.

What Are Liquidity Pools and Liquidity Providers?

In Uniswap-v1, the platform performs an exchange between \(Y\) and \(Z\) by implicitly using ETH as a via medium. This feature changes in Uniswap-v2, where a distinct smart contract can be created for direct exchanges between ERC-20 tokens. Adams et al (2020) recognize the added complexity of this change,Footnote 24 without explicitly outlining the new possibilities for arbitrage this generates. Much of the focus of this section, then, is to outline how Uniswap-v2 creates the possibility of three-point arbitrage that is absent in v1.

An Overview of its Function and Mechanics

While this primer takes a fairly deep look at AMMs and DEXs, it barely scratches the surface of advancements to financial instruments and institutions that are taking place in the DeFi space. In other words, there is much scope for exciting research to be done in the DeFi space. The Unswap-v3 whitepaper (Adams et al. 2021) proposes three important changes to v1 and v2, which we summarize briefly here.

The process of liquidity provision involves depositing an equivalent value of two different tokens into a pool. Routing properly to improve executions is the best way to avoid potential market maker induced shakeouts and impulse trades. Using a direct market access (DMA) broker to control your order routing ensures that market makers won’t take the other side of your trades. ECNs are the bane of market makers and empower individual traders with market maker-like features like placing hidden and iceberg orders. PL can be estimated without specifying dynamics for the marginal rate or the trading flow[8] and without specifying a parametric form for the level function.

Traders should pay more attention to time and sales over level 2 screens since those are actual trades versus the “intent” of trades. When you see a level 2 screen gyrating violently as bid/ask spreads gyrate wildly, but very few trades get posted on time and sales, it’s a sign of spoof attempts or manipulation. Many traders believe that market makers love to intentionally trigger knee jerk and panic reactions. Wholesalers trade shares for institutional clients and various broker-dealers not registered as market makers in particular stocks. Wholesalers deal in large volume pools often utilizing high frequency trading programs to optimize bundling and spread arbitrage strategies.

The result is a hyperbola (blue line) that returns a linear exchange rate for large parts of the price curve and exponential prices when exchange rates near the outer bounds. Traditional AMM designs require large amounts of liquidity to achieve the same level of price impact as an order book-based exchange. This is due to the fact that a substantial portion of AMM liquidity is available only when the pricing curve begins to turn exponential. As such, most liquidity will never be used by rational traders due to the extreme price impact experienced. Market makers can be both firms and individuals, but due to large capital requirements, most market makers are firms.

When needed, we will introduce the changes brought about in Uniswap-v2, and how this impacts the workings of the CPMM platform. There are three basic types of AMM, each with a different formula responsible for maintaining the integrity of their liquidity pool. These are constant product (CPMM), constant sum (CSMM) and constant mean (CMMM). Some projects, such as Balancer, use a mixture of these and thus are known as hybrid AMMs.

One of the primary advantages of AMMs is their ability to provide continuous liquidity. Liquidity pools ensure that there are always assets available for trading, regardless of the time or market conditions. Unlike traditional exchanges that rely on specific buyers and sellers, AMMs enable users to trade instantly, 24/7. An AMM, or automated market maker, removes the pitfalls that accompany regular crypto exchange trading. Centralized infrastructure and permissioned usage are replaced by algorithms and smart contracts, meaning that anyone with a suitable crypto wallet can transact in an anonymous manner. Automated market makers (AMMs) use math to ensure adequate liquidity within a decentralized exchange.

The main trade-offs with DEXs relate to the scalability of the underlying blockchain, which also comes with more latency and higher transaction fees. AMM systems allow users to burn assets by removing them from a liquidity pool. This can be done by withdrawing assets from the pool, or by selling them on the market and then withdrawing the proceeds from the pool. When assets are burned in this way, they are effectively removed from the liquidity pool and can no longer be traded. In contrast, AMMs, prevalent in DeFi, use algorithms to set prices and facilitate trades. Liquidity is provided by pools of tokens, not by individual buyers and sellers.
