constant product market makers

When expanded it provides a list of search options that will switch the search inputs to match the current selection. This risk can be especially pronounced in markets with low liquidity, or in times of market volatility. This function acts as a constant sum when the portfolio is balanced and shifts towards a constant product as the portfolio becomes more imbalanced. What he didnt foresee, however, was the development of various approaches to AMMs. Liquidity : This is the ability of an asset to be sold without affecting the price. [5] First be seen in production on a Minecraft server in 2012,[6] CFMMs are a popular DEX architecture. 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 most commonly used AMM is constant product AMM, but other AMM models are also deployed in decentralized finance (DeFi). Market makers are agents that alleviate this problem by facilitating trade that would otherwise not occur in those markets. 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. 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. Market makers are high-volume investors that "create a market" by quoting to buy and sell an asset simultaneously. The pool also takes a small fee ($r = 1 - \text{swap fee}$) from the amount of token 0 we gave. In practice, what would happen is that any arbitrageur would always drain one of the reserves if the reference relative price of the reserve tokens is not one. The CPMM spreads liquidity out equally between all prices, automatically adjusting the price in the . 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. 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. 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 -. saddle.finance. However, the actual price of a trade The law of supply and demand tells us that when demand is high (and supply is constant) Understanding this math is crucial to build a Uniswap-like DEX, but it's totally fine if you don't understand everything at this stage. Liquidity risk: As with any market, the prices of assets on a constant product AMM DEX are subject to supply and demand. in a permissionless system. From this, it is observed that when a user places an order of tokens $$\Delta x = \frac{x \Delta y}{r(y - \Delta y)}$$. Bootstrapping liquidity in an order-book-based exchange is an extremely tedious and expensive process. Even though Uniswap doesnt calculate trade prices, we can still see them on the curve. The above limitations are being overcome by innovative projects with new design patterns, such as hybrid automated market makers, dynamic automated market makers, proactive market makers, and virtual automated market makers. Also aiming to increase liquidity on its protocol, DODO is using a model known as a proactive market maker (PMM) that mimics the human market-making behaviors of a traditional central limit order book. Lastly, it is common to hear that algorithmic lending protocols like Compound are referred to as automated market makers. 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. The exact mechanics vary from exchange to exchange, but generally, AMMs offer deep liquidity, low transaction fees, and 100% uptime for as many users as possible. and states that trades must not change the product (. The first AMM were developed by Shearson Lehman Brothers and ATD. Since Uniswap pools are separate smart contracts, tokens in a pool are priced in terms of each other. Visually, the prices of tokens in an AMM pool follow a curve determined by the formula. Before AMMs came into play, liquidity was a challenge for decentralized exchanges (DEXs) on Ethereum. prices when making a trade: And thats the whole math of Uniswap! A liquidity pool is a smart contract that holds reserves of two or more tokens and allows anyone to deposit and withdraw funds from them, but only according to very specific rules. Bonding curves define a relationship between price and token supply, while CFMMs define a relationship between two or more tokens. Price-time priority market makers: These market makers prioritize orders based on the price and the time at which they are placed, with the highest price and earliest orders getting priority. V 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. We derive the replicating portfolio and greeks for a constant product market with bounded liquidity such as Uniswap v3. Since increase in liquidity is equal to increase in shares: Burning: This refers to the process of removing or destroyingan asset from circulation. As the legend goes, Uniswap was invented in Desmos. They do this by using a process called "liquidity provision," in which they act as both the buyer and the seller of an asset. 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 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. In this video, we explain how constant product automated market makers using a very simple story so you can. The formula for this model is X * Y = K. Users supply liquidity pools with tokens and the price of the tokens in the pool is determined by a mathematical formula. Instead of relying on the traditional buyers and sellers in a financial market, AMMs keep the DeFi ecosystem liquid 24/7 via liquidity pools. At this point, Augur V1 and Gnosis). AMMs fix this problem of limited liquidity by creating liquidity pools and offering. 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. The point at which ETH value in the liquidity pool reaches $550 is when it has: 10,488.09 DAI 19.07 ETH Impermanent Loss is the potential for a market maker to experience a loss due to changes in the relative prices of the assets that they are holding as part of their market making activities. AMM users supply liquidity pools with crypto tokens, whose prices are determined by a constant mathematical formula. rst proved that constant mean market makers could replicate a large set of portfolio value functions. 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]. On this Wikipedia the language links are at the top of the page across from the article title. 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. This new method of exchanging assets embodies the ideals of Ethereum, crypto, and blockchain technology in general: no one entity controls the system, and anyone can build new solutions and participate. Jun Aoyagi and Yuki Ito. 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. A distributed network for decentralized protocols enabling the most lucrative, fastest and protected operations in DeFi. Every trade starts at the point on the curve that corresponds to the current ratio of CFMMs incur large slippage costs and are thus better for smaller order sizes. . this new point. costs 0.001 ETH. Your trusted source for all things crypto. For a large part of the history of finance, market making activity was carried out by institutions with large capital and resources. In non-custodial AMMs, user deposits for trading pairs are pooled within a smart contract that any trader can use for token swap liquidity. in-game items that are hard to market make because of low liquidity). 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 formula is: When you trade in an AMM X and Y can vary but the result is always a constant. $$r\Delta x = \frac{xy - xy + x \Delta y}{y - \Delta y}$$ the larger the liquidity pool, the lower the price slippage) but there are additional dimensions that could be dynamic. 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. Francesco in Coinmonks Instead, there needed to be many ways to trade tokens, since non-AMM exchanges were vital to keeping AMM prices accurate. A qualified professional should be consulted prior to making financial decisions. 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. When assets are burned in this way, they are effectively removed from the liquidity pool and can no longer be traded. Before AMMs came into play, liquidity was a challenge for, (DEXs) on Ethereum. 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. 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. This is how markets work. 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. 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. 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. how it works. 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. We focus particularly on separability and on different invariance properties under scaling. CFMMs are the first class of AMMs to be specifically applied to real-world financial markets. So in the next part, well see how the mathematics Impermanent loss is the difference in value over time between depositing tokens in an AMM versus simply holding those tokens in a wallet. Demand is defined by the amount you want to buy, and supply is the . One of the most popular models adopted by automated market maker platforms is the constant product market maker (CPMM) model. We use x and y to refer to reserves of one pool, where x is the reserve This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. Instead of trading directly with other people as with a traditional order book, users trade directly through the AMM.. The change in $y$ is the amount of token 1 well get. (when we want to sell a known amount of tokens) and we can always find the input amount using the $\Delta x$ formula (when The same is true for any other pool, whether its a stablecoin pair or not (e.g. 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. must be monotone (intermediate value theorem), and it can be assumed WLOG that These AMMs set the prices of assets on a DEX. Unlike . Constant function market makers are a fundamental innovation for financial markets and have introduced an exciting new area for academic research around automated market making. we want to buy a known amount of tokens). The constant formula is a unique component of AMMs it determines how the different AMMs function. The ratio of tokens to add in a liquidity pool must be equal to the ratio of tokens before adding liquidity. For example, if the CFMM price is less than the reference market price, arbitrageurs will buy the asset on the CFMM and sell it on an order book-based exchange for a profit. tokens that the pool is holding. 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. Minting: Minting refers to the process of creating a new asset or increasing the supply of an existing asset. A note on privacy in constant function market makers. 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. $$r\Delta x = \frac{x \Delta y}{y - \Delta y}$$ it doesnt matter which of them is 0 and which is 1. And: This allows for variable exposure to different assets in the pool and enables swaps between any of the pools assets. (the token they want to buy). When does the tail wag the dog? 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! crucial to build a Uniswap-like DEX, but its totally fine if you dont understand everything at this stage. This example is from the Desmos chart made by Dan Robinson, When plotted, the constant product function is a quadratic hyperbola: Where axes are the pool reserves. 287K views 1 year ago You might be asking what an automated market maker is. The more assets in a pool and the more liquidity the pool has, the easier trading becomes on decentralized exchanges. Automated market makers (AMMs) are part of the decentralized finance (DeFi) ecosystem. This is due to the fact that a substantial portion of AMM liquidity is available only when the pricing curve begins to turn exponential. Minting: Minting refers to the process of creating a new asset or increasing the supply of an existing asset. This AMM enables the creation of AMMs that can have more than two tokens and be weighted outside of the standard 50/50 distribution. Liquidity provider: is an entity that provides assets to the AMM in order to increase the liquidity of a particular market and earn a small fee. 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. As such, most liquidity will never be used by rational traders due to the extreme price impact experienced. Our main results are an axiomatic characterization of a natural generalization of constant product market makers (CPMMs), popular in decentralized finance, on the one hand, and a characterization . 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. Notice that each of these formulas is a relation of reserves ($x/y$ or $y/x$) Constant product formula is probably the simplest and the earliest algorithm to come into the market. Anyone with an internet connection and in possession of any type of ERC-20 tokens can become a liquidity provider by supplying tokens to an AMMs liquidity pool. These AMM exchanges are based on a constant function, where the combined asset reserves of trading pairs must remain unchanged. Answers: a. In fact, these formulas free us from calculating prices! 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 fee is paid by traders who interact with the liquidity pool. The constant product market maker protocol is a form of the much known automated market maker (AMM) model. A constant product formula is one that does not change based on the size of the trade or asset that an investor is trading. For example: in 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. Stocks, gold, real estate, and most other assets rely on this traditional market structure for trading. Always do your own research (DYOR) and never deposit more than you can afford to lose. {\displaystyle \varphi } Arbitrage trades have been shown to align the prices reported by CFMMs with those of external markets. Keywords: Automatic market makers, market microstructure. For example, a liquidity pool could hold ten million dollars of ETH and ten million dollars of USDC. This button displays the currently selected search type. 2021. Conversely, the price of BTC goes down as there is more BTC in the pool. Only when new liquidity providers join in will the pool expand in size. demand: the more tokens you want to remove from a pool (relative to pools reserves), the higher the impact of demand is. This has made these rules popular in prediction markets (fixed cost of . Path dependence, in a nutshell, means that history matters. 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. 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. $$\Delta y = \frac{y r \Delta x}{x + r\Delta x}$$ 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. $18 d. $15 Well be focusing on and Liquidity providers normally earn a fee for providing tokens to the pool. This also holds true for AMMs. AMM systems allow users to burn assets by removing them from a liquidity pool. As I mentioned in the previous section, there are different approaches to building AMM. What is an automated market maker? This product remains constant during the token swap process such that for time t+1. 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. Users trade against the smart contract (pooled assets) as opposed to directly with a counterparty as in order book exchanges. These CFMMs will have price functions that best reflect the characteristics of their respective assets, resulting in less slippage and more efficient exchange. Rb - Number of Tokens of B present in the Liquidity Pool. Token prices are simply relations of reserves: $$P_x = \frac{y}{x}, \quad P_y=\frac{x}{y}$$. Because CFMMs encourage passive market participants to lend their assets to pools, they make liquidity provisioning an order-of-magnitude easier. In this article I explain what Automated Market Makers are, and dive deep into Constant Product Market Makers. Professional market makers who ensure that exchanges have enough liquidity, need to be able to rapidly cancel and update their orders when market prices move (which they always do!). For a liquidity pool with three assets, the equation would be the following: (x*y*z)^()=k. 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. It uses a hybrid of a constant sum and constant product, and arrives at quite a complex function below: Where x is the reserves for each asset, n is the number of assets, D is an invariant that represents the value in the reserve, and A is the amplification coefficient, which is a tunable constant that provides an effect similar to leverage and influences the range of asset prices that will be profitable for liquidity providers (i.e. 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. . To incentivize liquidity providers to deposit their crypto assets to the protocol, AMMs reward them with a fraction of the fees generated on the AMM, usually distributed as LP tokens. $$-\Delta y = \frac{- y r \Delta x}{x + r\Delta x}$$ Since Bancor introduced on-chain AMMs in 2017, there have been several notable improvements on different aspects of AMMs: . :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 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. This helps ensure that users can always buy or sell an asset on the DEX, even if there aren't any other buyers or sellers at the moment. Broadly speaking, market makers (MM) provide liquidity to the exchange they operate in, and they set "buy" and "sell" quotes for each 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.. Their trading activity creates liquidity, lowering the price impact of larger trades. When other users find a listed price to be acceptable, they execute a trade and that price becomes the assets market price. Get started. k is just their product, actual Because of this matching process, there is the possibility that some orders may take a while to get filled, if ever. 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. Were basically giving a pool some amount of token 0 and getting some amount of token 1. In contrast to regular market makers, AMMs function by using self-executing computer programs, also known as smart contracts. AMMs provide liquidity to the DEX by constantly buying and selling assets in order to keep prices stable. ; Guillermo Angeris, Alex Evans, and Tarun Chitra. "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. However, AMMs have a different approach to trading assets. the incentive to supply these pools with assets. $$x + r\Delta x = \frac{xy}{y - \Delta y}$$ 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. Well, this is the math of Uniswap V2, and were studying Uniswap V3. Here Is What I Found Out. $$r\Delta x = \frac{xy - x(y - \Delta y)}{y - \Delta y}$$ If the AMM price ventures too far from market prices on other exchanges, the model incentivizes traders to take advantage of the price differences between the AMM and outside crypto exchanges until it is balanced once again. CSMMs follow the formula x+y=k, which creates a straight line when plotted. So, if the price of token A increases, the price of token B must decrease in order to keep the constant product equal to the constant. ; Tarun Chitra, Guillermo Angeris, Alex Evans, and Hsien-Tang Kao. While automated market makers have been studied in both theory and practice, constant function market makers (CFMMs) are a zero to one innovation for both academic literature and financial markets. This implies a price of 1 ETH = 100 DAI. An early description of a CFMM was published by economist Robin Hanson in "Logarithmic Market Scoring Rules for Modular Combinatorial Information Aggregation" (2002). The equation x * y = k governs asset swaps on Uniswap, where x and y represent the quantities of two different assets in a liquidity pool, and k represents a value called the constant product invariant . Meanwhile, market makers on order book exchanges can control exactly the price points at which they want to buy and sell tokens. Pact offers multiple Automated Market Maker (AMM) capabilities to create the most efficient liquidity for market participants. In order for the market maker to not give away assets for free, 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. To learn more about AMMs, please read: Constant Function Market Makers: DeFi's "Zero to One" Innovation. Shell Protocol has similar goals but takes a different approach. Its like Curve in that the slippage is optimized for stablecoins and its like Balancer in that pool tokens are a weighted basket of assets, but it differs from both in that it uses a variety of tunable parameters. A simple and secure platform to build your crypto portfolio. Liquidity providers normally earn a fee for providing tokens to the pool. I bet youre wondering why using such a curve? 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. 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 The job of the pool is to give 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. We study axiomatic foundations for different classes of constant-function automated market makers (CFMMs). . 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. [8] It has been noted that this includes the intrinsic value of any negative-gamma derivative contract. How does the Constant Product Market Maker (CPMM) work? In this model, the weighted geometric mean of each reserve remains constant. This new method of exchanging assets embodies the ideals of Ethereum, crypto, and blockchain technology in general: no one entity controls the system, and anyone can build new solutions and participate. are the pricing functions that respect both supply and demand. 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. Constant Mean Market Maker (CMMM): It ensures the average price of assets in a particular market remains constant over time. 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 popular AMM is the Logarithmic Market Scoring Rule, which was developed in 2002 and is used for most prediction markets (e.g. They allow digital assets to be traded in a permissionless and automatic way by using liquidity pools rather than a traditional market of buyers and sellers. The structure of the paper is as follows. . 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. Most AMMs use a constant product market maker model. to the pool, which is added to the reserves. The smart contracts underlying the Uniswap protocol and the constant product formula automate the market making for you. The prices of assets on an AMM automatically change depending on the demand. A crowdfunded CFMM is a CFMM which makes markets using assets deposited by many different users. Typically, the exchange has to find market makers, have them write custom code for pricing and posting orders, and often directly provide accounts and funds on which to trade. This formula has the desirable property that larger trades (relative to reserves) execute at exponentially worse rates than smaller ones. [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). Curve (a.k.a. The first type of CFMM to emerge was the constant product market maker (CPMM), which was popularized by the first AMM-based DEX, Bancor.
