What is an Automated Market Maker AMM? AMMs explained

The profits obtained by the arbitrage traders come from liquidity providers’ pockets. For LPs, these losses are what is amm often greater than the profits earned through the pool’s fees and token rewards combined. When users trade on decentralized exchanges like Uniswap or Curve, they aren’t interacting with other traders; instead, they interact directly with a smart contract. This is a significant disadvantage for liquidity providers using an AMM. It occurs when the price of the deposited crypto assets deviates from their original price.

How can the current AMM model be improved?

As we stand on the brink of a new financial era, the role of AMMs cannot be overstated. They are more than just a technological innovation; they are a testament to the potential of decentralized systems and the promise they hold for a more equitable financial future. Embracing AMMs and the broader DeFi space requires a willingness to learn, adapt, and innovate, but the rewards can be significant for those who https://www.xcritical.com/ are ready to take on the challenge. Decentralized Finance (DeFi) has seen an explosion of interest on Ethereum and other smart contract platforms like BNB Smart Chain. Yield farming has become a popular way of token distribution, tokenized BTC is growing on Ethereum, and flash loan volumes are booming. The SushiSwap team launched what is known as a “vampire attack”, whereby a protocol attempts to steal LPs from a competitor by offering better rates and rewards.

This is achieved by maintaining liquidity pools—reservoirs of tokens that users can trade against. An Automated Market Maker is a type of decentralized exchange protocol that relies on a mathematical formula to price assets. Unlike traditional market systems, which need buyers and sellers to determine the price of an asset, AMMs use a predefined pricing algorithm.

Liquidity Providers and Liquidity Pools

In fact, LPs can end up worse off if these fluctuations are drastic and asset prices change substantially. Some decentralized exchanges (DEXs) facilitate trades directly between users and wallets. You can think of these types of trades as peer-to-peer (P2P) transactions between buyers and sellers. However, DEXs that execute transactions using AMMs are effectively peer-to-contract (P2C) transactions. These transactions occur without traditional order books or counterparties. Algorithms determine the rules for AMMs, and asset prices rely on a mathematical formula.

• “Impermanence” assumes that if the assets revert to the prices where they were originally deposited, the losses are mitigated.
• In essence, the liquidity pools of Uniswap always maintain a state whereby the multiplication of the price of Asset A and the price of B always equals the same number.
• Low trading volume means poor rewards for LPs which, ironically, means they will take their liquidity and go to another AMM where the rewards are better.
• In traditional systems, assets may be illiquid or not frequently traded, leading to outdated or inaccurate pricing.
• AMMs lower these barriers, allowing for the swift integration of new tokens or assets into the market.

Concentrated Liquidity Market Maker (CLMM)

Balancer made CMMM popular by pooling its liquidity into one CMMM pool rather than multiple unrelated liquidity pools. CMMMs stand out with some interesting use cases such as one-tap portfolio services and index investing. Conversely, centralized exchanges (CEXs) use an order book to match a buyer with a seller to execute a cryptocurrency trade at a mutually agreed exchange price. The AMM needs liquidity to perform trades, and that liquidity is provided by users like you and me.

Types of Automated Market Maker (AMM)

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. Impermanent loss occurs when the market-wide price between the tokens deposited in the AMM diverges in any direction. As a general rule, the bigger the diversion between the tokens’ prices after they’ve been deposited, the more significant the impermanent loss.

Algorithmically determined exchange prices

And even then, we’d still need to agree on price before the trade could take place. When Uniswap launched in 2018, it became the first decentralized platform to successfully utilize an automated market maker (AMM) system. AMMs are more than just a component of the DeFi ecosystem; they are a transformative force in the financial sector.

AMMs have really carved out their niche in the DeFi space due to how simple and easy they are to use. Decentralizing market making this way is intrinsic to the vision of crypto. In this regard, liquidity is an indicator or a measure of the “availability” or the speed at which an asset can be bought or sold without noticeably affecting its price stability. Today, you can “farm for yield” — maximize profits — by moving LP tokens in and out of different DeFi apps.

What Are Automated Market Makers (AMM)?

Simply put, automated market makers are autonomous trading mechanisms that eliminate the need for centralized exchanges and related market-making techniques. Liquidity pools combine the funds deposited by LPs for users of AMMs to trade against. An LP could provide one ETH to a Uniswap liquidity pool, along with £3,000 worth of the USDC stablecoin. LPs earn a portion of transaction fees when AMM users swap ETH or USDC from that liquidity pool. However, it is not uncommon for LPs to experience “impermanent loss” when the prices of assets fluctuate.

Built on Ethereum, the Uniswap decentralized exchange (DEX) has catalyzed the AMM space attracting colossal amounts of liquidity. 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.

Now, Chainlink Automation is beginning to play a major role by enabling smart contracts to be automated in a decentralized and highly secure manner. 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.

Automated market makers sound more complicated than they actually are — CoinMarketCap breaks down what AMMs are and how they work. Be careful when depositing funds into an AMM, and make sure you understand the implications of impermanent loss. If you’d like to get an advanced overview of impermanent loss, read Pintail’s article about it. 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.

Trading (or swapping) cryptocurrencies is one of the most common transaction types that contributes to the overall activity in the decentralized finance (DeFi) ecosystem. Arbitrage opportunities arise when a significant amount of a particular token is either added to or withdrawn from the pool. If a user wants to acquire ETH, they will go to the pool and deposit DAI in exchange for ETH. This injection of DAI increases its supply in the pool, causing its value to decrease, while the value of ETH increases due to its now reduced supply.

The constant, represented by “k” means there is a constant balance of assets that determines the price of tokens in a liquidity pool. 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. Conversely, the price of BTC goes down as there is more BTC in the pool. 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.
