Uniswap is undoubtedly the largest functional decentralized exchange (DEX) on the Ethereum blockchain network. It implements a unique exchange protocol with advantages such as trustless exchange of ERC20 tokens between users – a contrast to the “traditional order book model”.
Ideally, Uniswap bundles tokens into smart contracts that users can trade against. This gives each user the ability to swap tokens, add tokens to a pool (liquidity pool) while earning fees, and list tokens on Uniswap.
In this article, we will go into detail on how Uniswap works and how you, as a beginner, can make the most of all the possibilities it offers. In particular, Uniswap has a simple user interface for the best user experience. Still, Uniswap offers more than meets the eye, and you’ll learn more about everything behind the scenes. Let’s dive right in!
What is Uniswap and how does it work?
Uniswap is a unique exchange platform, especially as it is completely decentralized. This means that Uniswap is not owned, operated or controlled by any single company. Also, Uniswap utilizes a refreshing trading model known as “Automated Liquidity Protocol”, a concept that automatically links a swap transaction to its respective liquidity pool.
The Uniswap platform is essentially based on the Ethereum blockchain – the second largest cryptocurrency and is available on Celo. As a platform, Uniswap was implemented in 2018 for exchange and use. Since Uniswap is based on the Ethereum network, it is compatible with all ERC-20 based tokens and frameworks such as the MyEther and MetaMask wallets.
Basically, Uniswap runs on two smart contracts, the “Exchange” contract and the “Factory” contract.
Both contracts are automated computer programs that are designed for specific purposes and functions and are subject to conditions. For example, the factory smart contract serves to add new tokens to the Uniswap platform, while the exchange contract facilitates all processes associated with token exchange and “trading”. Although Uniswap has seen many improvements and is currently using the third version of its platform, ERC20-based tokens can still be exchanged via the upgraded Uniswap v.2 platforms.
How do Uniswap liquidity pools work?
Trading and exchanging tokens between Uniswap users is only possible with a liquidity pool. The best way to define a liquidity pool is a pool of tokens that allows users to swap between tokens and trade them for profit. Tokens in the liquidity pool are typically added by liquidity providers (LPs). Liquidity providers are essentially end users who tie their tokens to smart contracts and earn fees when other users or traders exchange their tokens when a liquidity pool is available.
Uniswap has gradually contributed to seamless digital currency transactions. The Uniswap V2 is even more intriguing as it allows traders to easily swap between ERC-20 tokens directly. Technically, Uniswap users do not trade with each other as this may not reduce the risk of token loss due to end-user dishonesty. Instead, the users are a liquidity token pool with a significant reserved amount of both tokens involved in that user’s trading.
Each Uniswap liquidity pool is intended as an opportunity to trade a fixed pair of ERC-20 tokens. However, there are many pairs and it can take forever for each user to find a suitable liquidity pool for their transaction. Still, Uniswap unburdens users by automatically directing traders to the appropriate liquidity pool for their transactions.
Uniswap solves the liquidity problem of centralized exchanges through the automated liquidity protocol. This includes incentivizing people trading the exchange when they become Liquidity Providers (LPs). In turn, Uniswap allows users to pool their funds, creating a reserve fund that is used to execute all trades and token swaps on the platform. Each listed token has its own pool for the user’s contribution.
This system helps buyers and sellers avoid waiting times like those experienced in a peer-to-peer trading scenario. Rather, the system allows for instant execution of any trade as long as the transaction is no larger than the liquidity pool itself. All LPs receive a token reward for the amount of money/liquidity they provide according to the pool’s total liquidity.
For example, if you deposit $5,000 into a $50,000 liquidity pool, you will receive 10% of the total reward the collection brings. The liquidity pool typically makes money by charging a fee for every swap and exchange transaction that occurs within the pool. In this case, Uniswap charges a flat fee of 0.30% for each trade and swap transaction on the platform.
If a liquidity provider chooses to stop providing, they will receive all the fees they have earned from the reserve. After receiving the reward, the tokens documenting the user’s ownership are destroyed. All the agreements and protocols discussed form the backbone of Uniswap’s liquidity pool.
With the upgrade to V2, Uniswaps gradually introduced a more promising reward, such as a log fee that can be toggled on and off by voting in the community. It remits a trading fee of 0.05% and 0.30% to a specific Uniswap fund to fund future development.
Uniswap V3 was recently deployed on the Celo blockchain to launch green asset liquidity pools and expand its reach to billions of smartphone users. As you may know, Celo is a mobile-first DeFi platform that enables fast, secure, and stable digital payments with almost no fees. So this collaboration makes perfect sense as Uniswap’s pools will be easily accessible to thousands of Celo users.
How does Uniswap work with Metamask?
A lot can be said about the almost endless possibilities that Uniswap offers. One of the most intriguing topics would be how Uniswap integrates and tweaks Metamask for more functionality and limitless potential. But how do the two work? What are the reasons Uniswap works seamlessly with a wallet like Metamask? Let’s find out!
Two notable features of Uniswap make it fully compatible with Metamask.
-
Uniswap is an open source protocol. That means anyone can create and build their frontend application for it, like Metamask or any other project that could be linked with Uniswap.
-
Uniswap is based on the Ethereum blockchain.
Metamask is more of a browser plugin or browser extension that doubles as a wallet. Being an ERC-20 compliant wallet, it can store and store a token based on the Ethereum blockchain, making it the top wallet choice for users looking to take advantage of the opportunities Uniswap offers. But it doesn’t take a genius to handle it or link your Uniswap to a Metamask wallet. It’s done quickly in two steps:
Now you can easily use your Metamask wallet to exchange and transact on your Uniswap.
What are Uniswap tokens used for?

The Uniswap platform is open source and uses blockchain-based smart contracts to facilitate decentralized trading between diverse and disparate digital assets.
Each pair of these digital assets are exchanged using the liquidity pools implementing smart contracts to rebalance after each trade to keep the entire system operational and advanced. The Uniswap blockchain can be likened to an electronic ledger and is constantly updated with real-time trading activity taking place between Uniswap users. This gives the impression that Uniswap is an exchange, but unlike most other exchanges, it does so without the involvement or involvement of any central authorities. Uniswap is an automated market maker.
All Uniswap operations are based on the Ethereum blockchain network and platforms.
Proof of work requires enormous computing and energy resources that support transaction processes and generate new cryptocurrencies.
These decentralized exchanges take place in a variety of ways, creating a market that balances supply and demand for trading between different tokens. The question arises: What is the purpose of the Uniswap token?
The Uniswap token (UNI) offers a unique opportunity that particularly benefits liquidity providers. Uniswap users who provide liquidity through staking enter into a digital and legal agreement not to trade or sell their digital assets for a period of time. However, they do so for rewards recorded in Uniswap tokens (UNI).
But that’s not all! They also participate in Uniswap governance. UNI token holders control the Uniswap platform, with voting rights being determined and distributed in proportion to UNI balances set by users.
In order to redeem their rewards from providing liquidity, the UNI representing the LP reward is paid out and then irrevocably destroyed to ensure transparency and security.
Digital currencies are evolving at a rapid pace, leading to an increasing influx of traders craving absolute decentralization. Platforms like Celo are making the technology more accessible to billions of users through their mobile-first DeFi solution. As a result, users of decentralized exchanges like Uniswap continue to increase.
However, a thorough understanding of how Uniswap works gives operational traders an edge to maximize opportunities with DEX exchanges like Uniswap. We examined the core concepts of Uniswap such as liquidity pools, liquidity providers, Uniswap tokens and integrated wallets like Metamask.
You can instantly maximize the opportunities Uniswap offers by downloading the Celo Alfajores wallet on your mobile device, giving you access to Uniswap’s liquidity pools.
