Automated Market Maker: A deep dive into Defi protocol

July 31, 2023

In recent years, the financial world has witnessed the rise of an innovative and disruptive technology known as Decentralized finance. 

Defi has various applications, one of which is Decentralized exchanges. Dex has been working through the protocol called Automated Market Maker (AMM). 

This revolutionary concept has transformed the landscape of Decentralized Finance (DeFi) and significantly impacted the way financial transactions are conducted. 

Let's dive into the topic,

What is an Automated Market Maker (AMM)?

A Decentralized Exchange uses a protocol known as an Automated Market Maker that allows automated trading of cryptocurrencies without the use of intermediaries. Traditional exchanges often rely on order books and centralized control, but AMMs operate on liquidity pools to facilitate trading. These pools are governed by smart contracts.

Interesting right? 

Let’s Deep dive to know the technical terms.

Decentralized Exchange

DEX is a fundamental concept that plays a crucial role in enabling the secure trading of digital assets. Users can transact with one another directly through a decentralized exchange (DEX), eliminating the necessity for a middle-man.

In a DEX, users retain ownership over their funds and assets rather than having them kept by a centralized organization.

Smart contracts

Smart contracts are automatic programs that run on a blockchain network, and they make decentralization possible. Transparency, security, and efficiency are all guaranteed throughout the transaction because of such smart contracts' automatic enforcement of the trade terms and conditions.

Liquidity Pool

A liquidity pool is the backbone of decentralized exchanges and is a collection of funds secured under a smart contract on a blockchain network. When a user contributes their digital assets to a liquidity pool, they contribute an equal number of tokens.

How Does an AMM Protocol Work?

1. Providing Liquidity:

Users can participate in the AMM by providing liquidity to the pool. They must deposit into the pool an equal number of each token to do this. In return, they receive liquidity pool tokens, representing their share of the total pool reserves. These tokens can later be used to withdraw their portion of the pooled assets.

2. Constant Product Market Maker (CPMM) Formula:

The price of the assets in the pool is determined by the Automated Market Makers using a mathematical method known as the Constant Product Market Maker (CPMM) or "x*y=k" formula. The formula ensures that the product of the quantities of both tokens in the pool remains constant.

For instance, the equation holds if a user swaps one token for another:

Final Token1 Quantity x Final Token2 Quantity= Initial Token1 Quantity x Initial Token2 Quantity.

To keep the product constant, the quantity of one token must drop when its supply rises in response to demand.

4. Automated Swaps:

When a user initiates a trade, the AMM smart contract automatically calculates the price based on the CPMM formula. The Automated Market Makers ensure that the trade occurs instantly at the current price without relying on order books or external parties.

5. Slippage:

Slippage, often known as the difference between the predicted price of an asset and the actual executed price as a result of changes in the pool's reserves, is a crucial factor to take into account when using automated market makers. High slippage occurs when larger trades are executed, impacting the execution price.

The Rise of Automated Market Maker Protocols: A Game-Changer in DeFi

The inception of Automated Market Makers, most notably popularized by the launch of Uniswap in 2018, marked a turning point in the world of decentralized finance. Automated Market Makers have eliminated the unnecessary use of traditional middlemen like brokers and custodians due to the power of blockchain technology and smart contracts. This democratized financial transactions, enabling anyone with an internet connection to participate in the DeFi ecosystem.

Advantages of Automated Market Makers

1. Reduction of dependence: 

AMMs operate on blockchain networks, making them inherently decentralized. This ensures that no single entity has control over the exchange's operations, reducing the risk of manipulation or malicious activity.

2. Global accessibility: 

Automated Market Makers have opened the doors of DeFi to a global audience. Anyone with an internet connection and a cryptocurrency wallet can easily participate, leveling the playing field for investors worldwide.

3. Increasing Efficiency: 

The automated nature of AMMs allows for instantaneous and continuous trading, providing users with seamless experiences even during times of heightened market volatility.

4. Secured transactions: 

Automated Market Makers are built on smart contracts, which are highly secure and transparent. This robustness minimizes the risk of hacks or fraudulent activities, instilling confidence in users.

5. Lowering Costs: 

By eliminating intermediaries, the AMM protocol significantly reduces transaction costs compared to traditional exchanges. This benefits user by enhancing their returns and fostering greater adoption.

The Road Ahead for Automated Market Makers

The integration of the Automated Market Maker protocol with other DeFi protocols and financial services holds immense potential. We anticipate that Automated Market Makers will become an integral part of various blockchain-based applications, driving further innovation in the financial industry.
