Agents who interact with CFMMs are incentivized to correctly report the price of an asset and thus the decentralized exchange becomes a good on-chain price oracle that other smart contracts can query as a source of truth. :D pool swap anchor liquidity lp amm solana uniswap automated-market-maker liquidity-provider constant-product uniswapv2 Updated on May 14, 2022 Rust JoeKaram78 / amm-frontrun-bot Star 16 Code Issues Pull requests The pool stays in constant balance, where the total value of ETH in the pool will always equal the total value of BTC in the pool. Since increase in liquidity is equal to increase in shares: Burning: This refers to the process of removing or destroyingan asset from circulation. When expanded it provides a list of search options that will switch the search inputs to match the current selection. 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. of Uniswap V3 is different. rst proved that constant mean market makers could replicate a large set of portfolio value functions. Because of this, CSMM is a model rarely used by AMMs. 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. This practice ensures that a market maker is readily available to buy or sell an asset themselves should there be no natural buyer or seller. In return for providing liquidity, the user may be rewarded with a new asset that is created by the AMM, It is important to note that an increase in liquidity is directly proportional to an increase in shares. While there has been a lot of excitement in the crypto community around automated market makers, there has been a lot of confusion over terminology. It occurs when the price ratio of the tokens they have deposited in a liquidity pool changes after they have deposited the tokens in the pool. Keywords: Automatic market makers, market microstructure. However, Curve has also recently launched support for more volatile token pairs with similarly concentrated liquidity. it simply prices the trade based on the Constant Product Formula. Smart contract risk: As with any decentralized platform, constant product AMM DEXs rely on smart contracts to facilitate trades and manage assets. 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. This also holds true for AMMs. vAMMs use the same x*y=k constant product formula as CPMMs, but instead of relying on a liquidity pool, traders deposit collateral to a smart contract. put some amount of one token into a pool (the token they want to sell) and remove some amount of the other token from the pool By overcoming an economics problem known as the coincidence of wants, CFMMs allow for an exchange to occur immediately, which could be important for certain use-cases (e.g. If we use only the start price, we expect to get 200 of token 1. $$-\Delta y = \frac{- y r \Delta x}{x + r\Delta x}$$ The pool also takes a small fee ($r = 1 - \text{swap fee}$) from the amount of token 0 we gave. This fee is paid by traders who interact with the liquidity pool. An interesting area of research would be to analyze the profit-maximizing fee that balances trade incentivization with liquidity incentivization. And we dont even need to calculate the prices! 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. Hybrid CFMMs enable extremely low price impact trades by using an exchange rate curve that is mostly linear and becomes parabolic only once the liquidity pool is pushed to its limits. I believe that these algorithmic markets utilize a type of AMM that is not a CFMM because the interest rate function is dynamic based on the utilization ratio and the goal is not to keep the interest rate constant. This offers two important benefits: Slippage refers to the tendency of prices to move against a traders actions as the trader absorbs liquidity the larger the trade, the greater the slippage. the larger the liquidity pool, the lower the price slippage) but there are additional dimensions that could be dynamic. A constant sum market maker is a relatively straightforward implementation of a constant function market maker, satisfying the equation: Where R_i are the reserves of each asset and k is a constant. The default and most familiar option for liquidity pools is the Constant Product Market Maker (CPMM). In effect, the function looks like a zoomed-in hyperbola. 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. Only when new liquidity providers join in will the pool expand in size. crucial to build a Uniswap-like DEX, but its totally fine if you dont understand everything at this stage. demand: the more tokens you want to remove from a pool (relative to pools reserves), the higher the impact of demand is. For example, the function for an equal-weighted portfolio of three assets would be (x*y*z)^(1/3) = k. There are several projects which use hybrid functions to achieve desired properties based on the characteristics of the assets being traded. the constant product function implements this mechanism! The change in $y$ is the amount of token 1 well get. This type of AMM will adjust its exchange rates automatically based on demand and supply to maintain that ratio.

It doesnt matter how volatile the price gets, there will eventually be a return to a state of balance that reflects a relatively accurate market price. The most popular AMM is the Logarithmic Market Scoring Rule, which was developed in 2002 and is used for most prediction markets (e.g. The main advantage of constant product AMMs is that they are relatively simple to understand and use. Proposition: For \(x>x^*\), constant product provides "higher" risk compensation than what market competition would yield, for \(x<x^*\) it is the reverse. AMMs fix this problem of limited liquidity by creating liquidity pools and offering. [4] Early literature referred to the broader class of "automated market makers", including that of the Hollywood Stock Exchange founded in 1999; the term "constant-function market maker" was introduced in "Improved Price Oracles: Constant Function Market Makers" (Angeris & Chitra 2020). It is also common to hear the term bonding curve when talking about CFMMs but it is incorrect to do so. This payoff structure suggests that liquidity providers should be actively monitoring changes in the liquidity pool and acting on changes quickly to prevent significant losses. ; Guillermo Angeris, Alex Evans, and Tarun Chitra. The above calculations might seem too abstract and dry. It uses the following functions: Where U(x) could be interpreted as a utility function comprised of a gain function, G(x), and a loss function, F(x); and x is the reserves of each asset. The pool stays in constant balance, where the total value of ETH in the pool will always equal the total value of BTC in the pool. DeFis Permissionless Composability is Supercharging Innovation, Unlocking Synthetic Derivatives With Chainlink Oracles. 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. A qualified professional should be consulted prior to making financial decisions. CFMMs incur large slippage costs and are thus better for smaller order sizes. arxiv: 1911.03380 [q-fin.TR] Google Scholar; Jun Aoyagi and Yuki Ito. xy = k. means that the price is determined based on the constant factor k. This has made these rules popular in prediction markets (fixed cost of . {\displaystyle V} Stocks, gold, real estate, and most other assets rely on this traditional market structure for trading. In non-custodial AMMs, user deposits for trading pairs are pooled within a smart contract that any trader can use for token swap liquidity. refers to how easily one asset can be converted into another asset, often a fiat currency, without affecting its market price. You just issued a new stablecoin, X, that is pegged to 1 USDT . to the pool, which is added to the reserves. Automated market makers (AMMs) are algorithmic agents that perform those functions and, as a result, provide liquidity in electronic markets. pool reserves. The more assets in a pool and the more liquidity the pool has, the easier trading becomes on decentralized exchanges. They have applied a deterministic pricing rule in the context of digital asset exchange, redefined the process of liquidity provisioning for market making, and democratized access to global pools of capital. Adding liquidity to a CFMM is simple but comes with some complex financial risks (impermanent loss, short volatility, long volatility/volume correlation, etc.). $21. A Constant Function Market Maker is a class of AMMs where the reserves of the assets in the pool can only change in a way that satisfies a certain mathematical relationship. The first type of CFMM to emerge was the constant product market maker (CPMM), which was popularized by the first AMM-based DEX, Bancor. Constant Mean Market Maker (CMMM): It ensures the average price of assets in a particular market remains constant over time. This is true, Trading any amount of either asset must change the reserves in such a way that, when the fee is zero, the product R_*R_ remains equal to the constant k. This is often simplified in the form of x*y=k, where x and y are the reserves of each asset. 2021. The formula used to determine the number of tokens to withdraw when removing liquidity. 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. Product-market fit is a moving target. As the "virtual . Uniswap uses a constant product market maker to maintain a correct ratio of tokens in the pool. This formula has the desirable property that larger trades (relative to reserves) execute at exponentially worse rates than smaller ones. 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. Only when new liquidity providers join in will the pool expand in size. The formula for this model is X * Y = K. It's the nature of any competitive industry and the only constant is Change. Automated Market Making: Theory and Practice, Improved Price Oracles: Constant Function Market Makers, Research Partner @ 1kx // Alum Blockchain@Berkeley, Berkeley-Haas, studied extensively in academic literature, Explain the difference between automated market makers and constant function market makers, Explore the pros & cons of constant function market makers and discuss future directions of CFMM designs and use-cases, It provides a minimum representation of state: we only need to know the. Uniswaps pioneering technology allows users to create a liquidity pool with any pair of ERC-20 tokens with a 50/50 ratio, and has become the most enduring AMM model on Ethereum. The prices of tokens in a pool are determined by the supply of the tokens, that is by the amounts of reserves of the Instead of matching buyers and sellers in an orderbook, these liquidity pools act as an automated market maker. 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. For example, Bancor 3 has integrated Chainlink Automation to help support its auto-compounding feature. Unlike . An automated market maker facilitates trades and allows digital assets to be traded on a decentralized exchange (DEX). Get started. Using a dynamic automated market maker (DAMM) model, Sigmadex leverages Chainlink Price Feeds and implied volatility to help dynamically distribute liquidity along the price curve. Understanding this math is Available at SSRN 3808755, 2021. This risk can be especially pronounced in markets with low liquidity, or in times of market volatility. The product k would actually be constant, if the swap fee was 0%. Oops! Because CFMMs encourage passive market participants to lend their assets to pools, they make liquidity provisioning an order-of-magnitude easier. This leads us to the following conclusion: pools decide what Recently, liquidity providers have also been able to earn yield in the form of project tokens through what is known as yield farming.. The structure of the paper is as follows. This design unfortunately allows arbitrageurs to drain one of the reserves if the off-chain reference price between the tokens is not 1:1. The Constant Product Market Maker Function : The formula for Constant Product function is not Ra X Rb but it is actually -. The more assets in a pool and the more liquidity the pool has, the easier trading becomes on decentralized exchanges. Stocks, gold, real estate, and most other assets rely on this traditional market structure for trading. Today, you can farm for yield maximize profits by moving LP tokens in and out of different DeFi apps. The constant product market maker protocol is a form of the much known automated market maker (AMM) model. Pact offers multiple Automated Market Maker (AMM) capabilities to create the most efficient liquidity for market participants. Augur V1 and Gnosis). $12 b. 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. Pact offers a familiar Constant Product Market Maker (CPMM) capability. This implies a price of 1 ETH = 100 DAI. means there is a constant balance of assets that determines the price of tokens in a liquidity pool. In this paper, we focus on the analysis of a very large class of automated market makers, called constant function market makers (or CFMMs) which includes existing popular market makers such as Uniswap, Balancer, and Curve, whose yearly transaction volume totals to billions of dollars. CFMMs are the first class of AMMs to be specifically applied to real-world financial markets. A simple and secure platform to build your crypto portfolio. Broadly speaking, market makers (MM) provide liquidity to the exchange they operate in, and they set "buy" and "sell" quotes for each asset. The information provided on the Site is for informational purposes only, and it does not constitute an endorsement of any of the products and services discussed or investment, financial, or trading advice. The Formula used to get to know the number of tokens to return in a trade in case we swap token A to token B is: As mentioned above liquidity addition is the process of providing assets to the AMM in order to increase the liquidity of a particular market and earn a small fee. This relationship between the prices of asset A and asset B is known as "constant product price elasticity." Instead of relying on the traditional buyers and sellers in a financial market, AMMs keep the DeFi ecosystem liquid 24/7 via liquidity pools. based on the input amount and vice versa: $$\Delta y = \frac{yr\Delta x}{x + r\Delta x}$$ $$x + r\Delta x = \frac{xy}{y - \Delta y}$$ $$-\Delta y = \frac{xy}{x + r\Delta x} - y$$ 1.0.0. . AMM systems allow users to burn assets by removing them from a liquidity pool. Liquidity Pool:a liquidity pool is a collection of assets that is used to facilitate trading in an AMM.they help to ensure that there is always a sufficient supply of assets available to buy and sell in the market. Francesco in Coinmonks Lets visualize the constant product function to better understand Phew! 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 $550 as well. [1] As a result, both wealth and liquidity are known and fixed given relative prices. Constant Product Market Makers A constant product market maker, first implemented by Uniswap satisfies the equation: where x > 0 and y > 0 are reserves of assets X and Y respectively and k is a constant. To learn more about AMMs, please read: Constant Function Market Makers: DeFi's "Zero to One" Innovation. A CFMM is described by a continuous trading function (also known as the invariant, AMM invariant, or CFMM invariant). The reserve of token 0 changes ($x + r \Delta x$), and the reserve of token 1 changes as well ($y - \Delta y$). In contrast to regular market makers, AMMs function by using self-executing computer programs, also known as smart contracts. in a permissionless system. On this Wikipedia the language links are at the top of the page across from the article title. Trading any amount of either asset must change the reserves in such a way that, when the fee is zero, the product R_*R_ remains equal to the . The converse result was later proven, providing a mechanism for constructing a . If The first and most well-known AMM is the Constant Product Market Maker (CPMM), first released by Bancor in the form of bonding curves within "smart token" contracts, and then further popularized by Uniswap as an invariant function [2][3]. This new technology is decentralized, always available for trading, and does not rely on the traditional interaction between buyers and sellers. $$r\Delta x = \frac{xy}{y - \Delta y} - x$$ 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. Alternatively, the founders often hack together a python script to offer liquidity with their own assets and simultaneously hedge their risk on other exchanges. AMMs fix this problem of limited liquidity by creating liquidity pools and offering liquidity providers the incentive to supply these pools with assets. With the Constant Product Market Maker (CPMM) capability, pairs act as automated market makers, ready to accept one token for the other as long as the constant product formula is preserved. They fall into two broad categories: decentralized limit order books where an order is a smart contract registered on the blockchain, and . The purple line is the curve, the axes are the reserves of a pool (notice that theyre equal at the start price). Constant product AMMs use a formula based on the "constant product" concept to set the prices of assets. When we add liquidity it is important to note that there should be no price change before and after adding liquidity. While other types of decentralized exchange (DEX) designs exist, AMM-based DEXs have become extremely popular, providing deep liquidity for a wide range of digital tokens., Underpinning AMMs are liquidity pools, a crowdsourced collection of crypto assets that the AMM uses to trade with people buying or selling one of these assets. This button displays the currently selected search type. Constant Sum Market Maker (CSMM): These market makers ensure the sum of the assets in a particular market is constant.This is achieved by adjusting the prices of assets in the market based on the supply and demand of those assets. At its core is a very 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. The profit extracted by arbitrageurs is siphoned from the pockets of liquidity providers, creating a loss. Curve offers low-price-impact swaps between tokens that have a relatively stable 1:1 exchange rate. Constant Function Market Makers This chapter retells the whitepaper of Uniswap V2. However, AMMs have a different approach to trading assets. 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. over the inventory amounts (commonly referred to as reserves),[7] such that the market maker only accepts trades which leave The point at which ETH value in the liquidity pool reaches $550 is when it has: 10,488.09 DAI 19.07 ETH As I mentioned in the previous section, there are different approaches to building AMM. This fee is paid by traders who interact with the liquidity pool. Recorded talk for the paper Improved Price Oracles: Constant Function Market Makers by Guillermo Angeris and Tarun Chitra for ACM's Advances in Financial Tec. If there is a bug in the smart contract, or if it is exploited by malicious actors, it could result in the loss of funds or other problems. 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. For a large part of the history of finance, market making activity was carried out by institutions with large capital and resources. ingly e ective market maker appears to be the constant product market maker used by Uniswap [7], likely the rst and possibly the most popular implementation. Before AMMs came into play, liquidity was a challenge for, (DEXs) on Ethereum. What is an automated market maker? 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. $$\Delta x = \frac{x \Delta y}{r(y - \Delta y)}$$. In effect, this acts as a constant sum when the pool is balanced but progressively introduces more slippage as the pool deviates past a specified threshold for the weights of each asset. Lets return to the trade formula and look at it closer: As you can see, we can derive $\Delta x$ and $\Delta y$ from it, which means we can calculate the output amount of a trade 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. Liquidity providers normally earn a fee for providing tokens to the pool. Notice that each of these formulas is a relation of reserves ($x/y$ or $y/x$) $$-\Delta y = \frac{xy - xy - y r \Delta x}{x + r\Delta x}$$ What worked in the past is a thing of the past and doesn't work anymore. Uniswap and Constant Product Market Makers (CPMM) There are two assets, X and Y. Denote by x the volume of X and by y the volume of Y in the reserves. At its core, a liquidity pool is a shared pot of tokens. equal to a constant). Market makers are agents that alleviate this problem by facilitating trade that would otherwise not occur in those markets.

Constant function market makers (CFMMs), such as constant product market makers, constant sum market makers, and constant mean market makers, are a class of first-generation AMMs made popular by protocols like Bancor, Curve, and Uniswap. The term constant function refers to the fact that any trade must change the reserves in such a way that the product of those reserves remains unchanged (i.e. Exchanges often have to handle some of the execution themselves by running an internal trading desk with controls to make sure theyre not front-running their customers. Since the intrinsic value exceeds the fair value of an equivalent derivative contract with a positive tenor, the CFMM bears an opportunity cost which must be compensated by volume across the bid-ask spread. As a liquidity provider you just need . Previous Multiple Fee Tiers Next StableSwap Invariant Market Maker (SIMM) Last modified 3mo ago The smart contracts underlying the Uniswap protocol and the constant product formula automate the market making for you. XY=K.The best example of a DEX that uses this is Uniswap and Bancor. 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. An automated market maker is a type of decentralized exchange that lets customers trade between on-chain assets like USDC and ETH. us a correct amount of token 1 calculated at a fair price. We can always find the output amount using the $\Delta y$ formula 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. Visually, the prices of tokens in an AMM pool follow a curve determined by the formula. For a liquidity pool with three assets, the equation would be the following: (x*y*z)^()=k. Thank you for signing up! Constant Product AMMs are simple to implement and understand. The protocol uses globally accurate market prices from Chainlink Price Feeds to proactively move the price curve of each asset in response to market changes, increasing the liquidity near the current market price. As a result, each trade also increases. 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. We derive the value function for liquidity providers . Uniswap works. Yes, I agree to receive email communications from Chainlink. Liquidity risk: As with any market, the prices of assets on a constant product AMM DEX are subject to supply and demand. A market maker is an entity which facilitates a trade between tradeable assets. plotting them on the graph. 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 This can be helpful for traders who want to make informed decisions about which assets to buy or sell. A constant sum function forms a straight line when plotting two assets, resulting in the equation x+y=k. Interestingly, this brings us back to the initial use-case of AMMs, which was information elicitation, except this time it is about the price of an asset rather than the probability of an event occurring! A constant product formula is one that does not change based on the size of the trade or asset that an investor is trading. 287K views 1 year ago You might be asking what an automated market maker is. Market makers like Citadel can be found in all types of markets from equity to currency exchanges to forex markets and are regarded as an important part of a well functioning and liquid market. 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. $$r\Delta x = \frac{xy - xy + x \Delta y}{y - \Delta y}$$ (DEX). Because the relative price of the two pair assets can only be changed through trading, divergences between the Pact price and external market prices create arbitrage opportunities. 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.
