The Decentralized Finance market has experienced exponential growth since 2020, but is still a relatively unexplored field of academic research.
This Bachelor thesis aims to contribute to the existing research on the Automated Market Makers and Decentralized Exchanges. It seeks to demonstrate their evolution by comparing the differences between various types of Decentralized Exchanges and evaluating the new feature of Uniswap v3 with the possibility of concentrated liquidity to achieve better liquidity efficiency.
The thesis shows that the Automated Market Maker model is promising on the one hand, as it potentially solves the existing liquidity inefficiencies and improves transparency. However, on the other hand, it is still uncertain from a regulatory and scalability perspective.

Research Objectives and Core Topics
This thesis examines the evolution and operational mechanisms of Decentralized Exchanges (DEXs) and Automated Market Makers (AMMs) in comparison to traditional Centralized Exchanges (CEXs), with a primary focus on evaluating the efficiency gains introduced by Uniswap v3's concentrated liquidity model.
- Functional mechanisms and comparison of CEXs versus DEXs
- Mathematical analysis of the Constant Product Market Maker (CPMM) model
- Evaluation of liquidity efficiency in Uniswap v3 through concentrated liquidity
- Assessment of systemic risks, including impermanent loss, frontrunning, and regulatory challenges
Excerpt from the Thesis
3.2 Concentrated Liquidity: Uniswap v3
The Uniswap v3 is based on the earlier constant product function by implementing the new feature of the market design – concentrated liquidity. The liquidity on Uniswap v1 and v2 is provided throughout the price range [0, ∞]. However, this is inefficient, especially if assets are assumed to trade near a certain price, which means that a large part of the assets held in LP is never touched. In contrast, liquidity providers on Uniswap v3 can choose their limited price range [pa, pb] to allocate their liquidity:
Moreover, this mechanism allows the market to decide where to distribute liquidity. Therefore, a rational liquidity provider can reduce the capital cost by concentrating liquidity in a range close to the current price and updating the custom positions. Unlike Uniswap v2, concentrated liquidity implies that each position in LP is unique, v3 protocol implemented non-fungible tokens for tracking liquidity (Adams et al. 2021, 1-3).
Due to the pricing function, the earlier versions of Uniswap and some AMMs have a price slippage, whereas LOB does not have this problem. Because of the range order, trading on Uniswap v3 is similar to LOB. Liao and Robinson (2022) compare the liquidity of Uniswap v3 with that of CEXs and demonstrate that Uniswap v3 has a significantly higher market depth for ETH-stablecoin pairs.

Frequently Asked Questions
What is the primary focus of this academic work?
The thesis explores the transformation of cryptocurrency trading through the shift from centralized limit order books to decentralized, automated liquidity protocols.
What are the central thematic areas covered?
The work focuses on market design, liquidity provision mechanisms, the evolution of Uniswap protocols, and the comparative risks between decentralized and traditional trading architectures.
What is the key research question addressed?
The study investigates whether DEXs can compete with CEXs, if Uniswap v3's concentrated liquidity offers superior efficiency, and if AMMs can bridge the gap toward traditional financial integration.
Which scientific methodology is applied?
The author performs an extensive literature review and a comparative analytical study, utilizing mathematical models (CPMM) and empirical observations from blockchain data (Dune Analytics, Kaiko) to evaluate exchange performance.
What is the main subject of the main chapters?
The main chapters analyze the evolution from traditional order books to AMMs, dissect the mathematical pricing functions used by Uniswap, and critique the challenges regarding scalability and security.
Which keywords best describe this research?
Key terms include Decentralized Finance (DeFi), Automated Market Makers (AMM), Liquidity Pools, Concentrated Liquidity, Impermanent Loss, and blockchain-based exchange infrastructure.
How does Uniswap v3 differ from previous versions?
Uniswap v3 introduces 'concentrated liquidity', allowing providers to choose specific price ranges for their capital, which significantly improves capital efficiency compared to the global range utilized in v1 and v2.
What is 'Impermanent Loss' in the context of this thesis?
Impermanent loss represents the discrepancy in value for a liquidity provider caused by the rebalancing of tokens in a pool when market prices fluctuate, potentially leading to lower returns than simply holding the assets.
What primary risks do AMMs face according to the author?
The author identifies significant risks including price slippage, frontrunning (specifically sandwich attacks), vampire attacks aimed at draining liquidity, and ongoing regulatory uncertainty.
