Decentralized Exchanges (DEX) have solidified their position in the blockchain and cryptocurrency industry. They provide solutions to centralization by allowing users to interact with their platforms in a self-custodial manner.
A prime example of a DEX is Uniswap. Since its founding in 2018, Uniswap has grown to become the largest decentralized exchange globally. It has also significantly contributed to the evolution of the cryptocurrency industry, particularly in the decentralized finance (DeFi) sector, by continuously integrating cutting-edge technologies.
Uniswap operates on the Ethereum blockchain, enabling peer-to-peer cryptocurrency trading without order books or intermediaries. Instead, it utilizes an automated liquidity protocol powered by Automated Market Makers (AMMs).
How Does Uniswap Work?
The Uniswap ecosystem comprises several critical components, each playing a vital role in ensuring seamless, automated operations. Below, we delve into these components, their functions, and how they contribute to an efficient trading ecosystem.
Automated Market Makers (AMM)
AMMs are the foundation of Uniswap. Unlike traditional order books, AMMs rely on liquidity pools to facilitate trades smoothly. These pools ensure constant liquidity within the DeFi ecosystem.
Traditional markets rely on buyers and sellers moderated by centralized entities. In contrast, AMMs operate in a permissionless, automated system powered by liquidity pools. Users contribute tokens to these pools, and predefined mathematical formulas determine token prices.
Uniswap’s AMM is a smart contract managing liquidity pools. It uses algorithms to determine token prices dynamically, based on supply and demand principles between traded ERC-20 tokens and liquidity pools.
Liquidity Pools and Providers
Liquidity refers to how easily an asset can be converted without affecting its market price. Early DEXs struggled with liquidity issues due to the novelty of the technology. AMMs revolutionized this by introducing liquidity pools and incentivizing providers.
Liquidity pools are collections of tokens used to facilitate decentralized trading. Smart contracts manage these pools, determining token prices in real time. Liquidity providers (LPs) contribute tokens to these pools and earn fees proportional to their contributions.

Uniswap’s Constant Product Formula
Uniswap employs a constant product formula to balance liquidity ratios for each token pair. This formula ensures fair market pricing by adjusting supply-demand dynamics dynamically.
How Has Uniswap Evolved?
Uniswap has undergone several upgrades since its 2018 launch. Below, we explore its major versions and key improvements.
Uniswap v1
The original version introduced basic DEX functionality, allowing ERC-20 token trading via Ethereum. It pioneered AMMs but had limited features.
Uniswap v2
Launched in 2020, v2 introduced ERC-20-to-ERC-20 trading pairs, eliminating ETH as an intermediary. It also reduced gas fees, improved efficiency, and added flash swaps.
Uniswap v3
The latest version allows LPs to set custom price ranges for liquidity provision, solving capital inefficiency issues. It remains the industry standard for DEXs.
Uniswap Token (UNI)
UNI, launched in 2020, is Uniswap’s governance token. Holders can vote on protocol changes, with voting power proportional to their UNI holdings. It’s an ERC-20 token stored in compatible wallets.
Trading on Uniswap DEX
Trading involves simple steps:
- Visit Uniswap’s website and connect an Ethereum wallet.
- Select the ERC-20 token to trade.
- Enter the amount; the platform calculates the equivalent.
- Click "Swap" and confirm the transaction.
- Tokens appear in your wallet post-execution.
