What is a Automated Market Maker (AMM)?

AMM are amongst the latest revolutionary technologies in the constantly changing space of decentralized finance (DeFi). 

AMMs support the exchange of expanding by disposing of more traditional middlemen and depending on smart contracts to permit direct user-to-user transactions. 

Here the article goes deep into how AMM works, its maturity in market, benefits and challenges of AMMs & future.

Understanding Automated Market Makers

At their core, AMMs are decentralized exchanges (DEXs) which use algorithms to price assets in liquidity pools. The pools are capitalized by liquidity providers (LPs) who contribute token pairs to them. 

The constant product formula x×y=k is the most common pricing algorithm, where X and Y are quantities of two tokens in the pool, respectively.

How AMMs Work

If a user wants to exchange tokens, they essentially interact right with the liquidity pool. For example, in a ETH/DAI pool, when someone would like to exchange their DAI for the equivalent amount of native token (ETH) or vice versa. 

This helps to make the price of a given token higher as users buy up that token, and lower if they are selling this is due to how the constant product formula works.

Advantages of AMMs

  1. Continuous Liquidity: AMMs have perpetual liquidity for pairs that allow for continuous trading even of much more thinly traded tokens. This is considerably better than traditional exchanges where liquidity deficits can cause more herding.
  2. Decentralization: Operating trustlessly, AMMs aim to give users more independence and final control over their assets, consistent with the greater DeFi ethos.
  3. Passive Income Opportunities: LPs will earn a portion of the trading fees from the pool, making it possible to generate passive income. This is an especially appealing option in a low-interest environment for traditional savings.
  4. Lower Fees: When you compare it to traditional exchanges, trading using AMMs generally has lower fees making it more affordable for both casual and old-time traders.

Challenges of AMMs

Even though they possess their own set of advantages AMMs, have some shortcomings which include:

  1. Impermanent Loss: Happens when the price of the asset deposited changes in comparison to its value at deposit time. Large moves in price can result with losses for LPs, which may not to be compensated by the trading fees they earned.
  2. Slippage: Big trades can massively affect the amount of tokens in a pool, causing slippage. This means that the traded tokens may ultimately be purchased or sold for a price different to that which was expected, leading to less advantageous trade outcomes.
  3. Smart Contract Vulnerabilities: Just as any other blockchain-based system bears its vulnerabilities in smart contracts so do AMMs. A high standard of security and reliability is crucial to protect against all instances including the loss of funds;
  4. Complexity and User Understanding: AMMs abstract the trading experience away from order books, but introduce entirely new complexities that retail users will need to learn about (liquidity provisioning) along with understanding the risks of impermanent loss.

Examples of Popular AMMs

The DeFi space is now flooded with a plethora of AMMs that each offer their own unique features and protocols including:

  1. Uniswap: The leading decentralized AMM, which anyone can list any token and provide liquidity (a critical piece of the DeFi ecosystem)
  2. SushiSwap: Derived from Uniswap, Sushisawp adjoined extra incentives for liquidity suppliers akin to yield farming​ opportunities.
  3. Balancer: Recognized for its customizable pool settings, Balancer helps in formation of multi-asset pools and can also adjust fee based on the deal size which provides you more complex liquid management choices.
  4. Curve Finance: Curve specializes in swapping between stablecoins so you can fully take advantage of low-slippage and impermanent loss, without all the other assets popping up.
  5. Kyber Network: Kyber is using its pro market makers to help manage their liquidity pools for better control and stability of the provided liquidity.

The Future of AMMs

The future of AMM is bright as decentralized finance (DeFi) technology continues to innovate and improve. Market events to look for:

  1. Enhanced Smart Contract Security: Users will eventually have more faith in smart contract as technology develops and their entanglements become more substantial, increasing the likelihood of security.
  2. Improved Liquidity Strategies: As the yield farming space matures, more sophisticated algorithms and strategies for managing liquidity pools will undoubtedly come on stream​. Often promising to maximize LP returns while minimizing risks like impermanent loss.
  3. Integration with Other DeFi Protocols: AMMs will increasingly integrate across the array of other DeFi protocol, enabling a greater web of more complex and interesting financial products. Under such symbiotic relationship, it will foster new mechanisms for the cryptos guaranteeing ways to earn returns acting on it.
  4. Regulatory Developments: Just as the space grows, regulatory frameworks will grow and adapt to protect consumers well maintaining innovation. These Regulations will play a critical role in determining the long term sustainability of AMMS.


Automated Market Makers (AMMs) are at the pinnacle of financial innovation - offering decentralized, efficient and user-friendly platforms for trading. 

Both of them have different types of challenges, along with their advantage and possible scopes they offer for the future - which is why it has been a core part in shaping up DeFi ecosystem. 

With the advancement of technology and further development in DeFi, AMMs has a lot more influence that can bring massive changes to finance going forward.
