Automated Market Maker (AMM)

Definition

Automated Market Maker, abbreviated as AMM, is a decentralized financial service, and it is used to enable the trading of digital assets without the need for order books and intermediaries such as stockbrokers and exchanges. Rather than directly connecting the buyers and sellers, which could be risky, it allows traders to be able to do this through their smart contracts, thus enabling trading to take place as it should without any unnecessary intermediaries or the need to hold any assets in large quantities, which would be cumbersome.

How it Works – Operational Mechanics

An automated market maker, therefore, functions through its pool of tokens collected from other users, referred to as liquidity providers. In the case of an exchange of one token for another, the AMM will exchange the two tokens depending on what is available in the pool. However, for this function, there is an algorithm used to calculate the rate of exchange, which depends on the proportion of the available tokens. In case one of the tokens is sold in large quantities, fewer of those tokens will be left in the pool, and the price will automatically be high. Additionally, the entire process is executed through the blockchain, where smart contracts execute the desired trade without human involvement.

Key Advantages

Among the main advantages of AMMs is their accessibility, as you only require crypto to become a liquidity provider by adding your crypto to the liquidity pool, on which you receive fees for trades executed with your contributions. AMMs facilitate 24/7 operation with zero downtime and zero reliance on any underlying authority. This perfectly epitomizes the spirit of the entire DeFi movement. Under the AMM system, the barriers for market participants are lower; users don’t require any accounts or approval from a central exchange control to participate in trades. Furthermore, AMMs allow users to trade a variety of cryptocurrencies, including those which may be unavailable on other traditional exchanges. Lastly, the prices are determined automatically; therefore, AMMs enable price quotes around the clock with zero presence of a buyer or seller on the other side of the trade.

Automated Market Maker Vs Order Book

In comparison to traditional systems like an order book, which is used by a traditional exchange, an automated market maker operates differently. In an order book system, buyers and sellers enter specific orders at specific prices, and when both orders match in terms of price, the system matches them. However, there needs to be adequate buyers and sellers, which can cause sluggish trade performance. In an AMM system, traders can trade at any time as long as there is adequate liquidity in the tokens.

Conclusion

Although AMMs have numerous benefits, equally important is the fact that despite their numerous benefits, AMMs are also risky. Prices of assets in AMMs may fluctuate due to large transactions or price differences. Liquidity providers also have to deal with impermanent loss due to changes in the token price of the pool. However, it is vital to understand that automated market makers have been instrumental in advancing the development of decentralized finance.
