constant product market makers

The constant product formula is a simple rule that allows anybody to spin up both a new market and a new AMM for a new pair of assets instantaneously. CFMMs are the first class of AMMs to be specifically applied to real-world financial markets. AMMs have become a primary way to trade assets in the DeFi ecosystem, and it all began with a blog post about on-chain market makers by Ethereum founder Vitalik Buterin. Product-market fit is a moving target. $$-\Delta y = \frac{xy}{x + r\Delta x} - y$$ CPMMs are based on the function x*y=k, which establishes a range of prices for two tokens according to the available quantities (liquidity) of each token. One of the most popular models adopted by automated market maker platforms is the constant product market maker (CPMM) model. money markets, he emphasized that AMMs should not be the only available option for decentralized trading. . As the "virtual . Arbitrage trades have been shown to align the prices reported by CFMMs with those of external markets. Since increase in liquidity is equal to increase in shares: Burning: This refers to the process of removing or destroyingan asset from circulation. Uniswap V2 / constant-product AMM implemented in Solana's Anchor -- add and remove liquidity, swap tokens, earn fees! StableSwap is primarily designed for trading stablecoins (coins pegged to a fiat currency), and has a different slippage profile compared to either of its predecessors. The pool also takes a small fee ($r = 1 - \text{swap fee}$) from the amount of token 0 we gave. $12 b. Shell Protocol has similar goals but takes a different approach. [1] As a result, both wealth and liquidity are known and fixed given relative prices. In Vitalik Buterins original post calling for automated or on-chain money markets, he emphasized that AMMs should not be the only available option for decentralized trading. A note on privacy in constant function market makers. Constant Product Market Maker (CPMM) The first type of CFMM to emerge was the constant product market maker (CPMM), which was popularized by the first AMM-based DEX, Bancor. A constant-function market maker (CFMM) is a market maker with the property that the amount of any asset held in its inventory is completely described by a well-defined function of the amounts of the other assets in its inventory. For a large part of the history of finance, market making activity was carried out by institutions with large capital and resources. At its core, a liquidity pool is a shared pot of tokens. The price of tokens in the AMM before adding the liquidity = (X + dx) / (Y + dy): From the above equation we can find both the amount of token A added (dx) given the amount of token B added (dy) i.e what is dy given dx ? The most popular of them is the Constant Function Market Makers (CFMM) [37], which maintain a mathematical invariant (for example, a product of the quantity of assets) during the trade. arXiv preprint arXiv:2103.01193, 2021. Constant Product Automated Market Maker | Solidity 0.8 - YouTube Code for constant product automated market maker.0:00 - State variables and constructor2:38: Internal functions -. Although Automated Market Makers harness a new technology, iterations of it have already proven an essential financial instrument in the fast-evolving DeFi ecosystem and a sign of a maturing industry. In fact, the creator of the term stated that bonding curve was actually intended to be used in the context of a bonded together curation community. Since AMMs dont automatically adjust their exchange rates, they require an arbitrageur to buy the underpriced assets or sell the overpriced assets until the prices offered by the AMM match the market-wide price of external markets. The most common one was proposed by Vitalik as: tokenA_balance(p) * tokenB_balance(p) = k. The constant, represented by k means there is a constant balance of assets that determines the price of tokens in a liquidity pool. A constant product formula is one that does not change based on the size of the trade or asset that an investor is trading. Synthetix is a protocol for the issuance of synthetic assets that tracks and provides returns for another asset without requiring you to hold that asset. By tweaking the formula, liquidity pools can be optimized for different purposes. As a result, both wealth and liquidity are known and fixed given relative prices. pool reserves. Saint Fame further legitimized the concept by selling shirts, Zora generalized the concept by creating a marketplace for limited-edition goods, and I expect to see many more projects using CFMMs for this use-case. Constant Product Market Makers. Cryptopedia does not guarantee the reliability of the Site content and shall not be held liable for any errors, omissions, or inaccuracies. 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. Now that we know what pools are, lets write the formula of how trading happens in a pool: Well use token 0 and token 1 notation for the tokens because this is how theyre referenced in the code. and states that trades must not change the product (. However, Curve has also recently launched support for more volatile token pairs with similarly concentrated liquidity. Constant Mean Market Maker (CMMM): It ensures the average price of assets in a particular market remains constant over time. AMMs are a financial tool unique to Ethereum and decentralized finance (DeFi). There are a variety of other approaches to AMMs for information aggregation, such as Bayesian market makers (often good for binary markets) and dynamic pari-mutuel market makers (often used for horse racing). 0.3% regardless of the size of the liquidity pool). Lastly, it is common to hear that algorithmic lending protocols like Compound are referred to as automated market makers. Liquidity Implication of Constant Product . I bet youre wondering why using such a curve? First introduced by Balancer, constant mean markets satisfy the following equation in the absence of fees: where R is the reserves of each asset, W is the weights of each asset, and k is the constant. is a "consistent payoff function",[8] that is, a payoff function which is concave, nonnegative, nondecreasing, and 1-homogenous, it is possible to construct a trading function which achieves Section 3 compares various cost functions from aspects of the . Where $P_x$ and $P_y$ are prices of tokens in terms of the other token. this new point. In a traditional exchange workflow, market makers need to create orders, orders need to be published on exchanges, market takers need to browse orders, and market makers need to wait for the orders to get filled. This AMM enables the creation of AMMs that can have more than. As the legend goes, Uniswap was invented in Desmos. [5] First be seen in production on a Minecraft server in 2012,[6] CFMMs are a popular DEX architecture. Constant Product AMMs are simple to implement and understand. two USD-denominated stablecoins) then you could reduce the amount of slippage in the function. On AMM platforms, instead of trading between buyers and sellers, users trade against a pool of tokens a liquidity pool. $$\Delta x = \frac{x \Delta y}{r(y - \Delta y)}$$. In this model, the weighted geometric mean of each reserve remains constant. Even though Uniswap doesnt calculate trade prices, we can still see them on the curve. Perpetual Protocol's vAMM uses the same x*y=k constant product formula as Uniswap. Surprisingly, there are multiple "Decentralized Finance: On Blockchain- and Smart Contract-Based Financial Markets", "A Practical Liquidity-Sensitive Automated Market Maker", "Logarithmic markets coring rules for modular combinatorial information aggregation", https://github.com/patrick-layden/HyperConomy, https://en.wikipedia.org/w/index.php?title=Constant_function_market_maker&oldid=1141745032, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 26 February 2023, at 15:49. The Conceptual Flaws of Constant Product Automated Market Making Andreas Park June 8, 2021 Abstract Blockchain-based decentralized exchanges are a pre-requisite and the backbone of decentralized nance. Many of first-generation AMMs are limited by impermanent loss and low capital efficiency, which impacts both liquidity providers and traders. . Suggested . And when demand is low, the price is also lower. What worked in the past is a thing of the past and doesn't work anymore. Today, you can farm for yield maximize profits by moving LP tokens in and out of different DeFi apps. The secret ingredient of AMMs is a simple mathematical formula that can take many forms. As a new technology with a complicated interface, the number of buyers and sellers was small, which meant it was difficult to find enough people willing to trade on a regular basis. We use x and y to refer to reserves of one pool, where x is the reserve Liquidity risk: As with any market, the prices of assets on a constant product AMM DEX are subject to supply and demand. The opinions and views expressed in any Cryptopedia article are solely those of the author(s) and do not reflect the opinions of Gemini or its management. Since AMMs usually have a fee, the product of the reserves is not really a constant in practice. Automated market makers (AMMs) are part of the decentralized finance (DeFi) ecosystem. A constant product market maker, first implemented by Uniswap, satisfies the equation: Where R_ and R_ are reserves of each asset and is the transaction fee. This fee is paid by traders who interact with the liquidity pool. CPMMs are based on the function x*y=k, which establishes a range of prices for two tokens according to the available quantities (liquidity) of each token. The name 'constant product market' comes from the fact that, when the fee is zero (i.e., = 1), any trade to must change the reserves in such a way that the product RR remains equal to the constant k. Because of this, CSMM is a model rarely used by AMMs. Under this option, liquidity providers need to supply each token in the pair with an equal or 50:50 value. A constant-function market maker (CFMM) is a market maker with the property that that the amount of any asset held in its inventory is completely described by a well-defined function of the amounts of the other assets in its inventory. The most common DEXes are so-called automated market makers (AMMs), smart contracts that pool liquidity and process trades as atomic swaps of tokens. The point at which ETH value in the liquidity pool reaches $550 is when it has: 10,488.09 DAI 19.07 ETH We derive the replicating portfolio and greeks for a constant product market with bounded liquidity such as Uniswap v3. Bootstrapping liquidity in an order-book-based exchange is an extremely tedious and expensive process. Constant Product Formula Automated Market Maker Variations Automated market makers (AMMs) allow digital assets to be traded without permission and automatically by using liquidity pools instead of a traditional market of buyers and sellers. Keywords: Automatic market makers, market microstructure. In other words, in the absence of fees, constant mean markets ensure that the weighted geometric mean of the reserves remains constant. As I mentioned in the previous section, there are different approaches to building AMM. Market makers do this by buying and selling assets from their own accounts with the goal of making a profit, often from the spreadthe gap between the highest buy offer and lowest sell offer. The relationship. Since Uniswap pools are separate smart contracts, tokens in a pool are priced in terms of each other. one of the creators of Uniswap. Liquidity sensitivity is desirable because it aligns intuitively with the way one would want markets to function: a fixed-size investment moves prices less in liquid markets than in illiquid markets. The name 'constant product market' comes from the fact that, when the fee is zero (i.e., = 1), any trade to must change the reserves in such a way that the product R R ETH/BTC). As a result, each trade also increases. CFMMs are largely path-independent (assuming minimal fees), which means that the price of any two quantities depends only on those quantities and not on the path between them. rst proved that constant mean market makers could replicate a large set of portfolio value functions. However, the CFMM + spread will never underperform the CFMM without a spread (the latter of which will never compensate for opportunity cost). The product of updated reserves must still equal $k$. In practice, because Uniswap charges a 0.3% trading fee that is added to reserves, each trade actually increases k. A constant product function forms a hyperbola when plotting two assets, which has a desirable property of always having liquidity as prices approach infinity on both sides of the spectrum. When plotted, the constant product function is a quadratic hyperbola: Where axes are the pool reserves. Still neglecting fees, let's imagine that after some trading, the price has changed; 1 ETH is now worth 120 DAI. Curve and Shell have demonstrated that there exists a design space for constant functions that are tailored for specific types of digital assets. Users trade against the smart contract (pooled assets) as opposed to directly with a counterparty as in order book exchanges. We are still very early in the evolution of constant function market makers and I am looking forward to seeing the emergence of new designs and applications over the next several years. plotting them on the graph. On a traditional exchange platform, buyers and sellers offer up different prices for an asset. However, users holding an open position in a synthetic asset are at risk of having their collateral liquidated if the price moves against them.. Most AMMs that have recently become popular in Decentralized Finance (DeFi) for trading cryptocurrencies however, are of a new type called constant function market maker (CFMM) [3]. An AMM uses an algorithm and the most common algorithm used by big decentralized exchanges is called a "constant-product market maker". building one specific type of AMMConstant Function Market Maker. unchanged. The change in $y$ is the amount of token 1 well get. This fee is paid by traders who interact with the liquidity pool. (DEX). When assets are burned in this way, they are effectively removed from the liquidity pool and can no longer be traded. This has made these rules popular in prediction markets (fixed cost of . Because CFMMs encourage passive market participants to lend their assets to pools, they make liquidity provisioning an order-of-magnitude easier. Since the technology is still pretty new, am looking forward to seeing advancement in the technology and in the entire DeFi ecosystem. Constant Product Market Maker (CPMM): A type of automated market maker that holds a fixed value for the ratio of two tokens it is trading, also known as a constant product formula. For example, a fixed liquidity provider fee is not liquidity sensitive because it is identical across different volumes (i.e. Demand is defined by the amount you want to buy, and supply is the Augur V1 and Gnosis). Balancer stretches the limits of Uniswap by allowing users to create dynamic liquidity pools of up to eight different assets in any ratio, thus expanding AMMs flexibility. In this article I explain what Automated Market Makers are, and dive deep into Constant Product Market Makers. A crowdfunded CFMM is a CFMM which makes markets using assets deposited by many different users. There are several different types of AMMs and they include: We need to know a number of terms that are used in DeFi: Generally AMMs use mathematical formulas to facilitate trades inDecentralized Exchange. Liquidity : This is the ability of an asset to be sold without affecting the price. The constant product market maker protocol is a form of the much known automated market maker (AMM) model. 1.0.0. . V Conversely, the price of BTC goes down as there is more BTC in the pool. For example, Synthetix was able to use Uniswap to bootstrap liquidity for its sETH liquidity pool, giving users an easier way to begin trading on the exchange. Because of this matching process, there is the possibility that some orders may take a while to get filled, if ever. Constant Price Market . The prices of tokens in a pool are determined by the supply of the tokens, that is by the amounts of reserves of the An arbitrageur notices the price difference between Coinbase and Uniswap and sees that as an opportunity for arbitrage that is basically an opportunity to make a profit. Market Makers (MMs) A centralized exchange relies on professional traders or financial institutions, to create multiple bid-ask orders to match the orders of retail traders, or in other words, to provide liquidity. Proposition: For \(x>x^*\), constant product provides "higher" risk compensation than what market competition would yield, for \(x<x^*\) it is the reverse. For example, a liquidity pool could hold ten million dollars of ETH and ten million dollars of USDC. The essence of current versions of automated market makers is best expressed through the constant product equation: x * y = k. Based on it, if a swap pool owns some units of token x and some units of token y, it prices trades so that the quantities of x and y resulting after the trade, when multiplied, are equal to a fixed constant, k. In Vitalik Buterins original post calling for automated or. A market maker faces the following demand and supply for widgets. it simply prices the trade based on the Constant Product Formula. Connect the world's APIs to Web3 with Chainlink Functions. And we dont even need to calculate the prices! This function acts as a constant sum when the portfolio is balanced and shifts towards a constant product as the portfolio becomes more imbalanced. This property implies that market makers should adjust the elasticity of their pricing response based on the volume of activity in the market. Automated market makers (AMMs) are a type of decentralized exchange (DEX) that use algorithmic money robots to make it easy for individual traders to buy and sell crypto assets. Users may contribute their assets to the CFMM's inventory, and receive in exchange a pro rata share of the inventory, claimable at any point for the assets in the inventory at that time the claim is made.[1]. Excessive Trading? To calculate the output amount, we need to find a new point on the curve, which has the $x$ coordinate of $x+\Delta x$, i.e. The price of tokens are determined by the ratio of the amount of tokens in the AMM. The pool gives us some amount of token 1 in exchange ($\Delta y$). In non-custodial AMMs, user deposits for trading pairs are pooled within a smart contract that any trader can use for token swap liquidity. $$\Delta x = \frac{x \Delta y}{r(y - \Delta y)}$$. Get started. Your trusted source for all things crypto. As we will see many times in this book, this simple requirement is the core algorithm of how DeFis Permissionless Composability is Supercharging Innovation, Unlocking Synthetic Derivatives With Chainlink Oracles. It might seem like it punishes you for trading big amounts. {\displaystyle \varphi } Uniswap popularized the mathematical formula: When we buy token 1 for token 0, we give some amount of token 0 to the pool ($\Delta x$). During periods of low volatility, Sigmadex can concentrate liquidity near the market price and increase capital efficiency, and then expand it during periods of high volatility to help protect traders from impairment loss. Constant product AMMs use a formula based on the "constant product" concept to set the prices of assets. Notice that each of these formulas is a relation of reserves ($x/y$ or $y/x$) Stableswap) had the insight that if the underlying assets are relatively stable-priced (e.g. And its the slope of the tangent line at When they have a larger variation of the two assets they are more likely to experience that impermanent loss. Instead, there needed to be many ways to trade tokens, since non-AMM exchanges were vital to keeping AMM prices accurate. A constant mean market maker is a generalization of a constant product market maker, allowing for more than two assets and weights outside of 50/50. to the pool, which is added to the reserves. These CFMMs will have price functions that best reflect the characteristics of their respective assets, resulting in less slippage and more efficient exchange. Such prices are called spot prices and they only reflect current market prices. Here Is What I Found Out. Every trade starts at the point on the curve that corresponds to the current ratio of For example, one could adjust LP fees based on trailing volatility, resulting in a stochastic pricing mechanism and the added benefit of volatility sensitivity for CFMMs. Simple question: does it pay to split an order? The structure of the paper is as follows. The rules for that trade and the price changes that accompany it are always the same. When we add liquidity it is important to note that there should be no price change before and after adding liquidity. saddle.finance. They do this by using a process called "liquidity provision," in which they act as both the buyer and the seller of an asset. This is how markets work. If there is not enough liquidity (i.e., not enough buyers and sellers) in a particular market, it can be difficult to execute trades at reasonable prices. This incentivises and rewards LPs proportionally to their ownership percentage of the pool. Learn how smart contracts work, use cases, and more. {\displaystyle V} Assuming zero fees for simplicity, the pool can . Automated Market Maker Platforms. In contrast to regular market makers, AMMs function by using self-executing computer programs, also known as smart contracts. An automated market maker is a type of decentralized exchange that lets customers trade between on-chain assets like USDC and ETH. The portfolio value is concave in the relative price of pool assets, short volatility, and can be effectively hedged in the same manner as a vanilla option. Adding liquidity to a CFMM is simple but comes with some complex financial risks (impermanent loss, short volatility, long volatility/volume correlation, etc.). The main advantage of constant product AMMs is that they are relatively simple to understand and use. Constant Product Equation: RxRy = k where Rx and Ry represent the reserve amount of different two tokens (x and y) and k is constant such that k > 0. Uniswap uses a constant product market maker to maintain a correct ratio of tokens in the pool. The opposite happens to the price of BTC in an ETH-BTC pool. As such, I believe that we will have a variety of CFMMs designed for asset types in addition to stablecoins, such as derivatives (e.g. It can be called a hybrid AMM since it uses elements from both the constant product and constant sum market makers. Alternatively, the founders often hack together a python script to offer liquidity with their own assets and simultaneously hedge their risk on other exchanges. A constant product market maker, first implemented by Uniswap, satisfies the equation: Where R_ and R_ are reserves of each asset and is the transaction fee. Curvature and market making. prices when making a trade: And thats the whole math of Uniswap! The constant product formula . 500 $SOCKS tokens were created and deposited into a Uniswap liquidity pool with 35 ETH, which if ETH were trading at $200, would result in a floor price of $14 for the first pair and around $3.5M for the 499th pair. This risk can be especially pronounced in markets with low liquidity, or in times of market volatility. ( Ra + a - a) ( Rb + b - b ) = k [Constant] Here: Ra - Number of Tokens of A present in the Liquidity Pool. 2019. If an AMM doesnt have a sufficient liquidity pool, it can create a large price impact when traders buy and sell assets on the DeFi AMM, leading to capital inefficiency and impermanent loss. By trading synthetic assets rather than the underlying asset, users can gain exposure to the price movements of a wide variety of crypto assets in a highly efficient manner. These AMMs set the prices of assets on a DEX. Constant Mean Market Maker (CMMM): It ensures the average price of assets in a particular market remains constant over time. Not only do AMMs powered by Chainlink help create price action in previously illiquid markets, but they do so in a highly secure, globally accessible, and non-custodial manner. Some of the famous market makers are Goldman Sachs, Binance, etc. of reserves must not change. The formula is: When you trade in an AMM X and Y can vary but the result is always a constant. Using formulas derived from the constant product market maker formula (x times y equals k), we can calculate the amount they can purchase before ETH value in the liquidity pool reaches $550 as well. . . Please try again. This also holds true for AMMs. Curve offers low-price-impact swaps between tokens that have a relatively stable 1:1 exchange rate. a - Number of Tokens of A the trader has . Automated Market Makers for Decentralized Finance (DeFi) Yongge Wang This paper compares mathematical models for automated market makers including logarithmic market scoring rule (LMSR), liquidity sensitive LMSR (LS-LMSR), constant product/mean/sum, and others. The purple line is the curve, the axes are the reserves of a pool (notice that theyre equal at the start price). value doesnt matter. the constant product function implements this mechanism! The paper introduces a new type of constant function market maker, the constant power root market marker. Concluding from the law of supply and demand, high demand increases the priceand this is a property we need to have AMMs use a constant product formula . And, magically, For a liquidity pool with three assets, the equation would be the following: (x*y*z)^()=k. Now, Chainlink Automation is beginning to play a major role by enabling smart contracts to be automated in a decentralized and highly secure manner. Eleven buyers are willing to buy at the following prices: $15, $14, $13, $12, $11, $10, $9, $8, $7, $6, $5. of Uniswap V3 is different.
