AMM Explained: Automated Market Makers & How They Work

A market maker facilitates the process required to provide liquidity for trading pairs on centralized exchanges. A centralized exchange oversees the operations of traders and provides an automated system that ensures trading orders are matched accordingly. In other words, when Trader A decides to buy 1 BTC at $34,000, the exchange ensures that it what is amm crypto finds a Trader B that is willing to sell 1 BTC at Trader A’s preferred exchange rate. As such, the centralized exchange is more or less the middleman between Trader A and Trader B. Its job is to make the process as seamless as possible and match users’ buy and sell orders in record time.

Dynamic Automated Market Maker (DAMM)

But the main mechanism that centralised exchanges employ to generate liquidity is through external market makers. These are B2B financial services that are paid to artificially generate trading demand for a specific coin, generally ones that are newly listed. With the upcoming launch of the CRV token, the team has indicated that all liquidity providers (starting from day 1) will be retroactively rewarded in CRV https://www.xcritical.com/ tokens. The CRV token will allow the governance of the protocol where users can introduce value capture mechanisms that benefit the CRV token holders and longterm liquidity providers the most.

Pros of Automated Market Makers

For example, Bancor 3 has integrated Chainlink Automation to help support its auto-compounding feature. 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. Liquidity providers earn more in fees (albeit on a lower fee-per-trade basis) because capital is used more efficiently, while arbitrageurs still profit from rebalancing the pool. For AMMs, arbitrage traders are financially incentivized to find assets that are trading at discounts in liquidity pools and buy them up until the asset’s price returns in line with its market price. They offset the currency risk of letting others trade against the pool’s assets.

What are Liquidity Pools and Liquidity Providers?

While definitions may vary, automated market makers essentially allow the automated trading of cryptocurrencies by using an algorithm to determine trade prices. With a traditional market maker of buyers and sellers, for example Binance, trades happen directly between parties using an order book. In contrast, the automated market maker model relies on smart contracts. Low liquidity can lead to price slippage, where the asset’s price significantly shifts between the initiation and completion of a trade.

Constant Product Market Maker (CPMM)

• The AMMs we know and use today like Uniswap, Curve, and PancakeSwap are elegant in design, but quite limited in features.
• A flat 0.2% fee is applied to every trade that transpires on the Kyber Network network.
• In other words, when Trader A decides to buy 1 BTC at $34,000, the exchange ensures that it finds a Trader B that is willing to sell 1 BTC at Trader A’s preferred exchange rate.
• You can use them in many types of payment, or trade them in the decentralized exchange.
• However, to prevent spam, the transaction to create an AMM has a special transaction cost that requires the sender to burn a larger than usual amount of XRP.
• Understanding these, staying informed about the latest developments, and approaching with caution are crucial for anyone looking to navigate this space successfully.

This model is implemented together with the token swap model in Bancor V2 protocol. Although the cloning of protocols is somewhat controversial, there are several clones of Uniswap available on multiple blockchains. If crypto tokens like Bitcoin are completely digital, what gives them real-world value? Discover how asset tokenization works, its benefits, and the challenges it faces. Uniswap is a market maker giant with over $3 billion total value locked (TVL), dominating over 59% of overall DEX volume. Due to the way AMMs work, the more liquidity there is in the pool, the less slippage large orders may incur.

Since launching, numerous clones and forks of the Uniswap protocol have emerged. As the protocol uses open-source code, this makes copying and cloning relatively simple. With that said, impermanent loss isn’t a great way to name this phenomenon.

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

Where a CEX has an Order Book managing offers from buyers and sellers through a centralised system a DEX uses an Automated Market Maker (AMM). An AMM combines Smart Contracts and algorithms to incentivise crypto holders to provide liquidity for trading pairs and automatically adjusts prices based on the changing liquidity ratio. Currently, all of the 0.04% trade fees go to the liquidity providers, on top of the lending protocols interest rates that were earned for the time in the pool.

AMMs use liquidity pools, where users can deposit cryptocurrencies to provide liquidity. These pools then use algorithms to set token prices based on the ratio of assets in the pool. When a user wants to trade, they swap one token for another directly through the AMM, with prices determined by the pool’s algorithm. Uniswap is an automated market maker that allows crypto users to deposit their assets into a shared pool, thereby enabling them to earn trading fees from the pool. A liquidity pool (LP) is a collection of funds held within a smart contract, which relies upon algorithms. Liquidity providers (LPs) are users who deposit tokens in DeFi smart contracts so that their crypto assets can be used for trading, borrowing, or lending by other users.

There are many different automated market maker protocols and options available across the DeFi ecosystem. For both traders and LPs, it is important to understand the make-up of each AMM’s liquidity pool. Uniswap, for instance, works on a fixed ratio between two pairs of tokens.

For example, a wallet developer can add their own 0.1% on top of the 0.2% network fee and keep the difference. In Uniswap, that fee goes directly to pool contributors, whereas in Balancer, a dynamic trade fee is determined by the pool owner and proportionally distributed to pool LPs.

Only when new liquidity providers join in will the pool expand in size. Visually, the prices of tokens in an AMM pool follow a curve determined by the formula. A liquidity pool is a pot of cryptocurrency tokens deposited by liquidity providers (LPs). LPs are able to earn rewards (protocol yields) for supplying tokens in the form of trade fees or other cryptocurrency tokens. In traditional markets such as stocks, bonds, gold, and crypto, there are usually at least three parties involved.

This risk is intrinsic to the AMM model and is more pronounced in pools with highly volatile assets. 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. Ultimately, this facilitates more efficient trading and reduces the impairment loss for liquidity providers. 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. By incorporating multiple dynamic variables into its algorithm, it can create a more robust market maker that adapts to changing market conditions. 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.

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. 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. The prices of assets on an AMM automatically change depending on the demand. For example, a liquidity pool could hold ten million dollars of ETH and ten million dollars of USDC. A trader could then swap 500k dollars worth of their own USDC for ETH, which would raise the price of ETH on the AMM.

Through this feature, Balancer has a competitive advantage of higher gas efficiency and deeper liquidity compared to many of its peers. However, the complexity of the platform may somewhat hinder its growth potential and ease-of-use for beginners. The competitive advantage of Uniswap lies in its peerless high liquidity, financial incentives in UNI rewards, and technological evolution. Users can manage their own digital identities, choosing what level of information they wish to provide to applications.

The issue of fees and scalability within AMMs and decentralised exchanges is a function of the wider battle among Smart Contract compatible chains. Ethereum’s imminent merge is being closely watched given the impact it might have along with the development of Layer 2 rollups which potentially reduce fees to pennies. A flash loan is a way to borrow crypto funds from a lending pool without collateral, provided the liquidity is returned within the space of one block confirmation. The depth of the particular market you want to trade into – the available liquidity – will determine any slippage in the price as you execute an order.
