At the start of the cryptocurrency boom around 10 years ago, the landscape used to be dominated by centralized exchange (CEX) giants like Coinbase and Binance. However, as the market developed, the fact that decentralized currencies require a decentralized exchange (DEX) started to dominate public sentiment.

Despite the fact that the DEX boom was observed in 2021-2022 and faded away with the onset of crypto winter and BTC’s notorious decline, the present-day interest in DEX services witnesses renewed growth. The total value locked (TVL) in DEX projects has risen considerably from its mid-2023 bottom, currently constituting over $21 bn. The current DEX trading volume is over $4.6 billion per 24 hours. Therefore, it makes sense to consider DEX development projects seriously again and make them a part of your business portfolio in the blockchain space. 

In this guide, the 4IRE team of blockchain architects sheds light on how to build a DEX and walks you through the process of DeFi staking platform development for entering the DeFi market with a superior platform. Read on to get the blueprint of Uniswap clone development and a better glimpse of what it takes in technical and financial terms to create a functional DEX platform. 

What Is Uniswap and How Does It Work? 

The first-ever project that responded to the users’ need for decentralization was Uniswap – a DEX protocol that transformed DeFi by introducing the Automated Market Maker (AMM) technology into crypto exchange mechanics. The project was a brainchild of Hayden Adams, inspired and supported by Vitalik Buterin’s Ethereum Foundation. It saw the world in 2018 and set the standard for DEX design and operations, with many DEX projects created by its token since then. 

The revolutionary AMM function of Uniswap has made it possible for users to exchange ETH and other ERC20 tokens without centralized intermediaries. Its advanced mechanism of stable liquidity provision, achieved with the help of user-generated liquidity pools and lucrative liquidity provider rewards, makes exchange rates predictable and fair. 

Besides being the technological standard-setter in the world of DeFi, Uniswap has enabled many appealing features, such as decentralized trading, instant liquidity, and community governance, with the help of UNI token ownership. These benefits over CEX trading arrangements have ensured the rising DEX user adoption and have contributed to the promotion of the crypto-financial ecosystem’s genuine decentralization. 

Key Features of Uniswap 

The main DEX platform features that Uniswap introduced in the DeFi industry are as follows: 

  • AMM. The AMM feature enables automated crypto trading with no slippage risks. Instead of using order books that CEXs utilize to execute trades, Uniswap uses liquidity pools for trading. This arrangement allows direct crypto asset exchange to and from the user’s wallet without transferring funds to the platform.  
  • Decentralized governance. The platform’s native UNI token enables decentralized governance by giving its owners voting rights on all notable changes in the Uniswap ecosystem. UNI holders also receive a share of the platform’s earnings and get lucrative rewards from UNI staking. 
  • Permissionless listing. Tokens traded on CEXs need to go through the approval process before getting listed. Uniswap has made listing permissionless, meaning that any ERC20-compatible token can be exchanged on the platform, provided there is a supplier and a buyer. This innovation has made DeFi more accessible for various crypto projects. 
  • Constant product formula. This mathematical algorithm determines the asset’s price and executes the actual trade. It also controls the constant supply of both exchanged tokens in the liquidity pools to guarantee price stability. 
  • LP fees. Liquidity pools are compiled of liquidity providers’ (LP) funds. By contributing their assets to a liquidity pool, LPs get entitled to a part of the revenue from the trade’s fees. Besides, they can allocate their tokens in liquidity pools to yield farming programs and get additional rewards.   
  • Absence of KYC requirements. Users don’t need to go through the KYC procedure to access Uniswap’s trading features, which enables privacy and ease of access. 

Uniswap’s Architecture and Required Tech Stack 

As we’ve already discussed above, Uniswap uses the AMM algorithm instead of an order book to execute trades. This algorithm has set the model for market making on decentralized exchanges by removing the need for centralized oversight over price fluctuations and progressive filling of orders based on the shifting demand. 

At the heart of the Uniswap architecture lies the proprietary Uniswap protocol – a P2P system that allows ERC20 token exchange on the Ethereum blockchain. It uses liquidity pools of two traded assets, the amount of assets in which changes dynamically and affects the real-time price of each. 

The permissionless nature of Uniswap is also one of its notable architectural features. The protocol’s permissionless design allows the system to stay universally open for public use without selective restrictions or interferences. The Uniswap protocol is also immutable, meaning that no party can reverse or pause trade execution. 

Uniswap’s operations are enabled by Ethereum smart contracts of several types, responsible for particular on-chain tasks like token swaps, fee distribution, and governance. The three main smart contracts on Uniswap are: 

  • Factory contract. This contract type is engaged when an exchange contract for a new token pair needs to be created. 
  • Pair contract. This contract type is responsible for the token swap execution and liquidity provision for a specified token pair. 
  • Router contract. This contract type routes the transactions to appropriate pools to ensure the token swap is done accurately. 

Another vital aspect of Uniswap’s architecture is the binary system of the Core and Periphery contracts. This arrangement serves the purposes of security by minimizing the amount of code interference in the Core and allocating the non-essential functions of the platform to the Periphery. 

Uniswap’s Tokenomics and Revenue Model 

The UNI token is at the heart of the project’s tokenomic and revenue models. At genesis, 1 billion UNI tokens were minted to unlock over four years of the vesting period. 60% of UNI tokens went to community members; team members and future employees owned 21.266% of UNI supply; 18% went to investors; under 1% went to advisors. 

At present, UNI holders can enjoy the following benefits: 

  • Use their voting rights on Uniswap governance proposals. 
  • Partly own the Community Treasury. 
  • Utilize the protocol fee switch. 

Uniswap’s business revenue comes solely from trade fees, distributed based on the chosen LP tier (0.05%, 0.3%, and 1%), each related to a specific rate of risk tolerance. Following the recent May’24 report, the platform processed over $90 billion in monthly volume, earning $159.25 million in fees. These are pretty impressive stats that add to the argument of Uniswap clone development as a project with sound ROI.

How to Develop a DEX Platform Like Uniswap? 

When starting to think over how to build a DEX, you need to consider two variants – building it from scratch or using a Uniswap clone script. When you choose custom development, you will need to build a DEX platform from zero by creating smart contracts powering your ecosystem and designing the full platform architecture. A clone script like that of Uniswap already contains all core features and modules for a DEX platform’s operation, such as token swaps, liquidity pools, staking, yield farming, profit distribution, etc. 

Each comes with specific pros and cons you should know before making the final decision. 

Building a DEX from Scratch 

Full control. When creating a custom DEX project from scratch, you get unique architecture, versatile functionality, and ultimate security.
