Automated Market Maker (AMM)

Automated Market Maker (AMM) is a term used to describe a decentralized trading mechanism that has become popular in the world of blockchain and cryptocurrencies. It is a type of algorithmic market maker that enables users to trade digital assets without the need for a central authority. In this article, we will explore the concept of Automated Market Maker and how it works, as well as its benefits and drawbacks.
What is an Automated Market Maker?
Automated Market Maker (AMM) is a decentralized trading mechanism that is designed to provide liquidity to a digital asset market. It operates on a set of algorithms that are programmed to automatically buy and sell assets based on supply and demand. An AMM creates a market for a particular digital asset by offering a price based on a mathematical formula that calculates the asset's supply and demand.
The AMM concept was introduced in 2017 by Bancor Network, a decentralized exchange that used an AMM algorithm. Since then, many other decentralized exchanges have adopted AMM as their primary mechanism for trading. Some of the popular AMM-based decentralized exchanges include Uniswap, Curve, and Balancer.
How does Automated Market Maker work?
AMM operates on a mathematical formula that is designed to maintain a balance between two digital assets. The formula is known as the Constant Product Market Maker (CPMM) formula, and it calculates the price of an asset based on its supply and demand.
The CPMM formula is simple: xy=k, where x and y represent the quantity of two assets in a market, and k is a constant. The formula implies that the product of the quantity of two assets in a market is constant. For instance, if there are 10 units of asset A and 5 units of asset B in a market, the product of xy will be 50. This means that the price of asset A and asset B will be inversely proportional to their quantity.
To illustrate further, let's assume that the price of asset A is 1 ETH, and the price of asset B is 0.5 ETH. If a user wants to buy asset A using asset B, they will receive 2 units of asset A for every unit of asset B they sell. This will increase the supply of asset A in the market, which will reduce its price. At the same time, it will decrease the supply of asset B, which will increase its price. This will ensure that the product of x*y remains constant.
Benefits of Automated Market Maker

1. Decentralization: AMM is a decentralized trading mechanism that eliminates the need for intermediaries such as brokers, banks, and other financial institutions. It provides users with a peer-to-peer trading experience where they can buy and sell assets without the need for a central authority.
2. Liquidity: AMM provides liquidity to digital asset markets by creating a market for a particular asset. It ensures that users can buy and sell assets at any time without the need for market makers or other intermediaries.
3. Transparency: AMM is transparent, and all transactions are recorded on a public blockchain. Users can track their transactions and see the price history of an asset.
4. Security: AMM is secure, and users' assets are held in a non-custodial manner. This means that users have full control over their assets, and there is no risk of a third party mismanaging their assets.

Drawbacks of Automated Market Maker

1. Impermanent Loss: Impermanent Loss is a significant drawback of AMM. It occurs when the price of two assets in a market changes. The automated trading algorithm will buy and sell assets based on the CPMM formula, which can result in a loss for liquidity providers.
2. Limited Asset Coverage: AMM is currently limited to digital assets that are compatible
