Decentralized Exchanges (DEXs) have cemented their place in the blockchain and cryptocurrency industry. They provide a solution to centralization by allowing users to interact with their platform in a self-custodial manner. A prime example of one of the leading DEXs is Uniswap. Since its creation in 2018, it's become the largest DEX in the world. According to DefiLlama's Total Value Locked (TVL) ranking for DEXs, Uniswap sits on top with a TVL of over $4 billion, surpassing competitors like Curve Finance and PancakeSwap.

Uniswap has made a significant contribution to the evolution of the cryptocurrency industry, especially within the decentralized finance (DeFi) sector, as it continues incorporating the latest technology into its platform. Interested to find out more about Uniswap and how it managed to become a leader among DEXs? Read on as we cover everything you need to know about Uniswap and the UNI token.
What is Uniswap?
Uniswap is a decentralized exchange that operates on the Ethereum blockchain. It's a cryptocurrency trading platform that allows traders to engage with one another on a peer-to-peer basis. Uniswap doesn't employ order books or intermediaries to facilitate transactions. Instead, it uses an automated liquidity protocol operated by Automated Market Makers (AMMs).
How Does Uniswap Work?
The Uniswap ecosystem is made up of several components, each playing a role in ensuring the automation process works 24/7 without interruption.
Automated Market Maker (AMM)
Automated market makers are the foundation of Uniswap. Instead of order books where traders pair with their counterparts, AMMs provide a liquidity pool that seamlessly facilitates trading. AMMs ensure constant liquidity in the DeFi ecosystem via liquidity pools to support transactions.
Uniswap's AMM is a smart contract that manages the pools deployed when trades execute on the DEX. It uses an algorithm to determine a token's effective price during active trading. Assets' prices on Uniswap are determined based on the principles of supply and demand between the traded ERC-20 tokens and the liquidity pools.
Liquidity Pool and Liquidity Providers
A liquidity pool is a crowdsourced pool of cryptocurrencies or tokens used to facilitate trades in a decentralized manner. Smart contracts manage digital assets in a liquidity pool. Meanwhile, a liquidity provider refers to anyone contributing tokens to a liquidity pool to provide liquidity in a DEX or a DeFi ecosystem.
Stakers — also called liquidity providers — contribute to the liquidity pool on Uniswap. Traders pay a fee of about 0.3% when transacting on Uniswap, which is distributed among liquidity providers based on their contributions.
The Uniswap Constant Product Formula
Uniswap integrates a constant product formula to balance the liquidity ratio of every cryptocurrency pair. The formula balances the supply-demand ratio and the price between both pairs, ensuring market value remains fair while maintaining liquidity.
Arbitrage Traders
Arbitrage traders are important to the Uniswap ecosystem. They seek out price discrepancies across multiple exchanges and use them to secure gains. This creates a win-win relationship between the AMM and arbitrage traders — the AMM achieves efficient prices, while arbitrage traders enjoy lower-risk gains.

How Has Uniswap Evolved?
Uniswap has changed over the years since launching in 2018. A series of updates and protocol adjustments led to different protocol versions.
Uniswap v1
Uniswap v1 is the earliest version of the protocol with the basic attributes of a DEX. Its key feature was implementing the AMM model, which used a constant product formula for liquidity pools.
Uniswap v2
Uniswap v2 introduced ERC-20 to ERC-20 trading pairs, eliminating the need for ETH as an intermediate token. It also offered a new price oracle system to reduce the possibility of price manipulation.
Uniswap v3
Uniswap v3 allows liquidity providers to set custom price ranges within which they want to provide liquidity. This update solves the problem of capital inefficiency seen with undefined liquidity ranges.
Uniswap v4
Uniswap v4 aims to elevate the user experience further and is scheduled to roll out in Q3 of 2024. The updated DEX version improves various elements, with a particular emphasis on making the user interface more intuitive.
UniswapX
UniswapX is a permissionless, open-source, Dutch auction-based protocol that aims to improve core features of Uniswap v2 and v3 in scalability and MEV protection. Key features include enhanced security, flexible trading mechanisms, and cross-chain swaps.
The Uniswap (UNI) Token
Uniswap launched UNI in 2020 as a governance token on the Uniswap platform. It's an ERC-20 token built on the Ethereum platform. UNI holders preserve the right to vote on changes and improvements in the Uniswap protocol.
Uniswap (UNI) Tokenomics
UNI has a maximum supply of 1 billion, with 753 million UNI tokens currently in circulation. Sixty percent of UNI tokens are allocated to the community, most of which have already been distributed to early Uniswap adopters.
Utility of UNI
UNI tokens are primarily used for governance and voting rights in determining the future of Uniswap. While some commentators claim that UNI lacks utility beyond governance, Uniswap enthusiasts argue that UNI tokens offer voting power to dictate the platform's direction.
Trading on Uniswap DEX
Trading on Uniswap involves a few simple steps:
- Visit the Uniswap website and connect your Ethereum wallet.
- Select the ERC-20 token you want to trade.
- Input the amount you wish to trade.
- Click "Swap" and confirm the transaction.
- The trade will execute, and tokens will reflect in your wallet.
Uniswap's Impact on the DeFi Sector
Uniswap has played an important role in promoting DeFi. It has boosted the sector by supporting decentralized exchange infrastructure, permissionless listings, liquidity provisioning, and token price discovery.
The Final Word and Next Steps
Uniswap remains a market leader among DApps for being the DEX with the highest trading volume in the DeFi space. Its continuous innovation ensures its position as a bastion for DeFi in the crypto community.
