What’s the Difference Between Automated Market Makers (AMMs) and Dex?

What Are AMMs?

AMMs, also known as "automated market makers," are novel decentralized instruments that facilitate the autonomous trading and exchange of cryptocurrencies. AMMs help automate the process of liquidity provision and eliminate the need for intermediaries when exchanging crypto assets. They are created using self-executable smart contracts and help determine the price of tokens and provide liquidity.

What Is DEX?

A decentralized exchange, or DEX, is a blockchain application that powers a peer-to-peer marketplace for trading cryptocurrencies. DEXs provide their users with full custody over their assets and allow traders to conduct the exchange of crypto assets without any intermediary or centralized entity. DEXs use automated algorithms and smart contracts to connect and match traders.

Differences Between AMMs and DEX

Both AMMs and DEXs focus on eliminating intermediaries in crypto trading. However, their method of accomplishing this goal is different. AMM pricing is set by algorithms and executed essentially as "peer-to-contract" transactions. Before AMM integration, most swaps on DEXs occurred via order books and peer-to-peer sales.

Some of the critical differences between AMMs and DEXs include:

• AMMs provide liquidity for illiquid markets, exposing traders to rare tokens regardless of liquidity pool or order size. Regular DEXs don't have liquidity pools. Instead, they rely on order books to pair and match willing traders.
• AMMs utilize mathematical formulas pegged to asset pricing, while DEX is asset-based pricing pegged via peer-to-peer transactional agreements.
• AMMs are peer-to-contract (P2C) protocols designed to improve current DEX performance and shortcomings. On the other hand, DEX applications utilize peer-to-peer (P2P) trading without intermediaries or oversight.

AMMs are generally seen as an improvement over the traditional DEX model, which utilizes order books to match traders and complete crypto transactions. While AMMs offer the advantage of liquidity and efficiency, there is also the risk of slippage for large-scale orders and impermanent loss for the liquidity providers.

Regardless of these risks, most DEXs today utilize the AMM model. As technology evolves, solutions to these drawbacks may emerge and allow AMM-based DEXs to become the preferred choice for crypto traders.
