Uniswap is a decentralized exchange (DEX) that makes it easy for users to swap an ERC-20 token for another ERC-20 token without the need of a centralized intermediary. With a DEX, traders do not have to deposit their tokens on an exchange and be exposed to the security risks of a centralized exchange. 

Users just need an Ethereum wallet like Metamask and they can immediately start swapping tokens. Users can then swap tokens directly without the need of an orderbook. This works using an Automated Market Maker (AMM) where Liquidity Providers (LP) deposit tokens into the smart contract and this liquidity then provides a price quote to traders without relying on any professional market makers. Liquidity Providers are compensated with a 0.3% trading fee for providing liquidity on the protocol.

Uniswap refers to an open-source protocol built on top of the Ethereum blockchain. It represents an exquisite solution to simplify the process of  ERC-20 token swaps without any centralized third-parties. That means users have the autonomy to manage their funds without depending on any centralized resources.

However, the lack of liquidity, such as insufficient funds passing through the platforms, prevented these decentralized exchanges from getting popular among liquidity providers.

That said, what sets Uniswap apart from the rest is it does not use an order book to determine prices. Instead, the protocol works by following an equation, where the total liquidity remains constant within the pool. And for the model to work, it involves liquidity providers to create a liquidity pool that sustains the decentralized trading and lending. That includes listing and swapping ERC-20 tokens without an order book.

The Uniswap protocol was inspired by the concept of the on-chain automated market maker (AMM) by Vitalik Buterin. Uniswap primarily uses the pricing mechanism Constant Product Market Maker Model, a variant of the Automated Market Making (AMM) system that holds liquidity pools for traders to trade against.

Subsequently, in May 2020, Uniswap introduced the updated version— Uniswap V2, along with liquidity pools. Unlike its predecessor (V1), users can swap between ETH and a single ERC-20 token, whereas V2 uses Wrapped Ether (wETH) in core contracts where users can pool ERC-20 tokens directly with any other ERC-20 tokens. Plus, prices became more reliable and more difficult for price manipulation.

The automated market maker (AMM) technology is the main innovation that enables the protocol to work. AMM controls the Uniswap pools supplying the tokens needed to execute trades. Uniswap's AMM algorithm figures out the real price of a token during a trade based on how supply and demand change between the tokens in these liquidity pools.

When consumers transact with one of Uniswap's liquidity pools, they now pay a transaction fee of 0.3 percent. Each participant in the liquidity pool gets a portion of these costs based on the staked portion of the pool. For instance, if the total fees generated were $200 and you contributed 60% of the liquidity to the pool, you would receive $120. Profits made from transactions are distributed among users (the platform does not collect any transaction fees).

How Do Liquidity Pools Work?

The liquidity pools are liquidity reserves locked in a smart contract, typically funded by liquidity providers. And stablecoins like USDT, DAI are the main constituent of the pool. Since Uniswap exists in a permissionless environment, and liquidity pools are the backbone for Uniswap, it is vital to comprehend its fundamentals. 

Basically, anyone can be a liquidity provider (LP), and to be an LP, you need to deposit an equivalent value of ETH and ERC-20 tokens into the pool. One of these AMM features is you can provide liquidity regardless of the liquidity pool’s size. In exchange, you’ll earn a reward in the form of liquidity tokens according to your contribution to the pool. That also means the number of unique tokens you receive is proportional to the pool’s liquidity. These liquidity tokens are used to track your contribution to the pool, distribute your share of the transaction fees, and for multitude usage across DeFi apps (dApps). 

In these liquidity pools, the total liquidity derived from the product of the two types of tokens always remains constant, following this simple equation X × Y = K, in which the total liquidity remains constant.

Let’s understand how this equation works using the ETH/USDT liquidity pool as an example. If a user buys ETH (x) from the ETH/USDT pool, the supply of USDT (y) will be more than the ETH after a transaction is made. When the ETH supply is lesser, naturally, there will be a price surge and vice versa. That is where the total liquidity (k) remains constant to determine the pricing. Generally, the larger the liquidity pool, the easier it is to process large orders. However, slippage does happen as the x and y’s ratios are not on a linear scale.

Historical Timeline:

June 2017: Vitalik publishes the article “On Path Independence,” introducing the concept of AMM.

November 2018: Uniswap V1 is released, supporting only conversions between ETH and ERC20 tokens.

March 2020: Uniswap V2 is released, allowing for the exchange of any ERC20 tokens.

September 2020: Tokens are issued to resist the vampire attack by Pancakeswap.

May 2021: Uniswap V3 is released, increasing LP capital efficiency and introducing the concept of concentrated liquidity.

June 2023: Uniswap V4 is proposed, introducing Hooks and Singleton concepts, still under development, expected earliest in Q1 2024, following the Dencun upgrade.

July 2023: Uniswap X is released, aggregating on-chain and off-chain liquidity, with MEV protection.

# Impact of Fee Switch on Token Traded on Uniswap

The fee switch has long been one of the most discussed topics within the Uniswap community. At present, 100% of trading fees are split by LPs based on their contribution to liquidity reserves. The fee switch refers to a portion of these fees being diverted to the Uniswap DAO treasury as a protocol fee.

In August, a 120-day pilot for activating the fee switch went to a Consensus Check on Snapshot where 99.99% of voters voted “Yes” in favor of the pilot. Per the proposal, the pilot would be tested on the following three pairs in which 10% of the respective liquidity provider fee would go to the Uniswap DAO treasury:

• DAI-ETH: 0.05% LP fee

• ETH-USDT: 0.3% LP fee

• USDC-ETH: 1.0% LP fee

The proposed pilot aims to quantify how LPs will re-deploy their liquidity provisioning in response to the fee switch. If the pilot makes it through the final stage of the governance process and the implementation is considered a success by the Uniswap community, the next major decision for Uniswap governance would be to decide how the protocol fees are utilized. The term “fee switch” does not create any expectation that protocol fees will be paid out to UNI tokenholders, but instead gives tokenholders new tools to leverage in furthering the growth and mission of the protocol.

In Q3’22, the three pairs accounted for 4.34% of the total volume traded. At the proposed 10% fee split, the pairs would have generated more than $850,000 for the Uniswap DAO treasury.

The above table shows trades done over 24 hours in the top 5 DEXs. We see that Uniswap v2 has the most growth exceeding 3,147 % with the largest trading volume in that period followed by Curve.

Moreover, while looking at comprehensive stats, the following plot depicts the number of trade takers recorded over seven days, from March 5th, 2024 to March 11th, 2024, suggesting a general increase from around 55,000 trade takers on March 5th to nearly 75,000 on March 11th.

Using Amberdata DEX API we can analyze top 5 decentralized exchange (DEX) platforms by trading volume. Uniswap leads the list with over 1.5 million trades and a staggering trade amount of $94.27 billion, experiencing a trade growth of 389,547.25%. SushiSwap follows closely with 22,527 trades and $105.72 billion in trade volume. PancakeSwap, Balancer, and Zerox Exchange also demonstrate significant trading activities. These DEX platforms play a crucial role in the decentralized finance (DeFi) ecosystem, providing users with decentralized trading options for various cryptocurrencies and tokens.

The growth trend is also in favor of UniswapV3. Nonetheless, SushiSwap and Curve Finance exhibit significant trading volume. This indicates they are strong contenders attracting a sizeable portion of DEX users.

Decentralized Exchanges (DEXs) are becoming increasingly popular for trading cryptocurrencies without relying on centralized platforms. Understanding user activity across different DEXs can be insightful for investors and developers. This analysis dives into the estimated total number of users on various DEXs in the last 24 hours,

The dominance of PancakeSwap with an estimated 1.8 million users in the last 24 hours. SushiSwap follows with a significant presence at 420,000 users. Uniswap (v3) and Quickswap hold positions as established players with user bases exceeding 200,000 in this hypothetical day. Curve and Theta round out the chart with user estimates of 110,000 and 75,000 respectively.

While this data offers a snapshot, it highlights potential trends. PancakeSwap's substantial user base suggests it caters to a broader audience or offers features attractive to a larger user pool. SushiSwap's strong presence indicates its continued relevance in the DEX landscape. Notably, Uniswap (v3) figures suggest healthy user adoption despite being a newer version of the popular Uniswap protocol.

Upward trends are present but not as significant as those of Uniswap v2. Events such as the launch of Uniswap v3 in the past and Pancakeswap version 4 could be contributing factors.

Examining various metrics like user growth, trading volume, and trade count provides a multi-faceted view of Decentralized Exchange (DEX) popularity.
