What Is Uniswap? A Complete Guide to the Decentralized Exchange
Uniswap is a popular decentralized trading protocol, known for its role in facilitating automated trading of decentralized finance (DeFi) tokens. An example of an automated market maker (AMM), Uniswap launched in November 2018, but has gained considerable popularity this year thanks to the DeFi phenomenon and associated surge in token trading. Uniswap now serves as critical infrastructure for decentralized finance, empowering developers, traders, and liquidity providers to participate in a secure and robust financial marketplace.

What is Uniswap and how does it work?
Uniswap is a protocol that allows anyone to create and access liquidity pools for any pair of ERC-20 tokens on the Ethereum blockchain. ERC-20 tokens are a standard for smart contracts that enable the creation of fungible tokens that can be exchanged on the Ethereum network. Some examples of ERC-20 tokens are Dai, USDC, WBTC, LINK, UNI, and many more.
A liquidity pool is a collection of funds that are locked in a smart contract to facilitate trading between two tokens. For example, there can be a liquidity pool for DAI/USDC, which contains some amount of DAI and USDC tokens. Anyone can trade between DAI and USDC by interacting with this pool, without the need for an intermediary or a centralized exchange. The price of each token in the pool is determined by a constant product formula, which ensures that the relative supply and demand of each token is reflected in the exchange rate.
Anyone can also become a liquidity provider (LP) by depositing an equal value of two tokens into a pool. For example, if someone wants to provide liquidity for the DAI/USDC pool, they need to deposit some amount of DAI and USDC into the pool. In return, they receive liquidity tokens, which represent their share of the pool. Liquidity providers earn fees from every trade that occurs in their pool, proportional to their share of the total liquidity. The fees are automatically added to the pool, increasing the value of the liquidity tokens over time.
Uniswap also has its own native token, called UNI, which was launched in September 2020. UNI is a governance token, which means that holders can vote on proposals to change or upgrade the protocol. UNI also entitles holders to claim a portion of the protocol fees that are generated by Uniswap v3, the latest version of Uniswap that was released in May 2021.
Uniswap v3 introduces some major improvements over Uniswap v2, such as:
- Concentrated liquidity: This feature allows LPs to choose what price ranges they want to provide liquidity for, instead of covering the entire curve from 0 to infinity. This way, LPs can increase their exposure to their preferred assets and reduce their downside risk. It also enables more capital efficiency and lower slippage for traders.
- Multiple fee tiers: This feature allows LPs to choose from different fee levels (0.05%, 0.30%, or 1%) depending on the volatility and demand of each pair. This way, LPs can be appropriately compensated for taking on varying degrees of risk.
- Oracles: Uniswap v3 improves the quality and accessibility of its price oracles, which are used by other DeFi protocols and applications to obtain accurate and reliable price data. Uniswap v3 oracles can provide time-weighted average prices (TWAPs) on demand for any period within the last ~9 days.
What are the benefits and risks of using Uniswap?
Uniswap offers several benefits for users who want to trade or provide liquidity for DeFi tokens, such as:
- Permissionless: Anyone can use Uniswap without having to register an account, verify their identity, or comply with any regulations. This makes Uniswap accessible to anyone with an Ethereum wallet and an internet connection.
- Censorship-resistant: Uniswap is decentralized and runs on smart contracts that cannot be controlled or manipulated by any central authority or intermediary. This makes Uniswap resistant to censorship, shutdowns, or interference from governments or corporations.
- Transparent: Uniswap is open-source and audited by third-party security firms. All transactions and activities on Uniswap are recorded on the Ethereum blockchain and can be verified by anyone. This makes Uniswap transparent and trustworthy.
- Innovative: Uniswap is constantly evolving and introducing new features and upgrades to improve its user experience and functionality. Uniswap also supports the development and integration of other DeFi protocols and applications, creating a vibrant and diverse ecosystem.
However, Uniswap also comes with some risks and challenges that users should be aware of, such as:
- Volatility: The prices of DeFi tokens can fluctuate significantly and unpredictably, depending on the market conditions and sentiment. This can expose traders and LPs to potential losses or gains, depending on their strategies and risk appetite.
- Impermanent loss: This is a phenomenon that occurs when the price of one token in a pool changes relative to the other. This causes the pool ratio to deviate from the initial 50/50 split, resulting in a loss of value for the LPs compared to holding the tokens individually. Impermanent loss is more pronounced when the price change is large and the pool is composed of highly correlated or volatile tokens.
- Gas fees: Uniswap transactions require gas fees to be paid to the Ethereum network for processing and validation. Gas fees can vary depending on the network congestion and demand, and can sometimes be very high, especially during peak periods. This can reduce the profitability and efficiency of trading and providing liquidity on Uniswap.
- Smart contract risks: Uniswap relies on smart contracts to execute its functions and operations. Smart contracts are essentially code that can have bugs, errors, or vulnerabilities that can be exploited by malicious actors or cause unintended consequences. While Uniswap has been audited and tested extensively, there is no guarantee that it is completely secure and flawless.
How to use Uniswap to swap, provide liquidity, and stake tokens?
To use Uniswap, you need to have an Ethereum wallet that supports web3, such as MetaMask, Coinbase Wallet, or Trust Wallet. You also need to have some ETH and ERC-20 tokens in your wallet to trade or provide liquidity. You can obtain ETH and ERC-20 tokens from other exchanges or platforms, or by using services like Ramp or Wyre that allow you to buy crypto with fiat currency.
Once you have your wallet set up and funded, you can visit the Uniswap app and connect your wallet to it. You will then be able to access the following features:
- Swap: This feature allows you to exchange one token for another at the current market rate, minus a 0.3% fee (for v2) or a variable fee (for v3) that goes to the LPs. You can also use this feature to swap ETH for any ERC-20 token, or vice versa, without having to use an intermediary token like WETH. To swap tokens, you need to select the token you want to sell and the token you want to buy, enter the amount you want to swap, review the price impact and slippage tolerance, and confirm the transaction. You will then receive the swapped tokens in your wallet.
- Pool: This feature allows you to provide liquidity for any pair of ERC-20 tokens, or create a new pair if it does not exist yet. You can choose between v2 or v3 pools, depending on your preference and strategy. To provide liquidity, you need to select the pair you want to join or create, enter the amount of each token you want to deposit, review the pool share and price range (for v3), and confirm the transaction. You will then receive liquidity tokens in your wallet that represent your stake in the pool. You can also use this feature to add or remove liquidity from existing pools, or migrate your liquidity from v2 to v3.
- Vote: This feature allows you to participate in Uniswap governance by voting on proposals or delegating your votes to others. To vote, you need to have UNI tokens in your wallet or in a supported protocol (such as Compound or Aave).
How does Uniswap compare to other DEXes?
Uniswap is one of the most popular and widely used decentralized exchanges (DEXes) on the Ethereum blockchain. It allows users to swap any ERC-20 token without the need for a centralized intermediary or a custodian. However, Uniswap is not the only DEX in the market, and there are other platforms that offer different features and advantages. Here are some of the main competitors of Uniswap and how they compare:
- SushiSwap: SushiSwap is a fork of Uniswap that launched in August 2020. It has the same functionality as Uniswap, but it also has its own governance token, SUSHI, that rewards liquidity providers with a share of the protocol fees and voting rights. SushiSwap also has some additional features, such as BentoBox (a lending platform), Kashi (a margin trading platform), and MISO (a token launchpad). SushiSwap is compatible with multiple blockchains, such as Ethereum, Binance Smart Chain, Polygon, Fantom, and xDai.
- PancakeSwap: PancakeSwap is a DEX that runs on the Binance Smart Chain (BSC), a blockchain that is faster and cheaper than Ethereum. It uses an AMM model similar to Uniswap, but it also has its own governance token, CAKE, that rewards liquidity providers and stakers. PancakeSwap also has some unique features, such as lottery, prediction market, NFT marketplace, and farms (yield farming pools). PancakeSwap supports BEP-20 tokens, which are the equivalent of ERC-20 tokens on BSC.
- 1inch: 1inch is a DEX aggregator that sources liquidity from various DEXes, such as Uniswap, SushiSwap, Balancer, Kyber, and more. It uses a smart routing algorithm that finds the best prices and lowest slippage for each trade. It also has its own governance token, 1INCH, that rewards users and liquidity providers. 1inch supports multiple blockchains, such as Ethereum, Binance Smart Chain, Polygon, and Optimism.
These are just some of the examples of DEXes that compete with Uniswap in terms of features, performance, and user base. Each DEX has its own pros and cons, and users should do their own research before choosing which one to use.
What Are the Difference between Uniswap v1, v2, and v3?
Uniswap is a decentralized exchange (DEX) that allows users to swap any ERC-20 token on the Ethereum blockchain without the need for a centralized intermediary or a custodian. Uniswap uses an automated market maker (AMM) model, which relies on liquidity pools to facilitate trading. Liquidity providers (LPs) can deposit tokens into these pools and earn fees from every trade that occurs in their pool. Uniswap also has its own governance token, UNI, which gives holders voting rights and a share of the protocol fees.
Uniswap has been upgraded three times since its launch in November 2018, introducing new features and improvements to the protocol. Here are the main differences between Uniswap v1, v2, and v3:
- Uniswap v1 was the original version of Uniswap that only supported one liquidity pool: ETH/ERC-20. To trade any other pair of tokens, users had to go through ETH as an intermediary token, which increased the cost and slippage. Uniswap v1 also used Vyper as its programming language and ERC-20 as its standard for liquidity tokens.
- Uniswap v2 was launched in May 2020 and introduced several enhancements over v1, such as direct ERC-20/ERC-20 pools, which eliminated the need for ETH bridging and reduced trading fees. Uniswap v2 also improved its price oracles by using time-weighted average prices (TWAPs) to prevent price manipulation. Uniswap v2 also switched to Solidity as its programming language and added some new features, such as flash swaps and protocol charge.
- Uniswap v3 was released in May 2021 and brought some major innovations to the protocol, such as concentrated liquidity, which allowed LPs to choose the price ranges they wanted to provide liquidity for, instead of covering the entire curve. This increased the capital efficiency and rewards for LPs, as well as reduced the slippage for traders. Uniswap v3 also introduced multiple fee tiers (0.05%, 0.30%, or 1%) for different pairs, depending on their volatility and demand. Uniswap v3 also improved its oracles by providing on-demand TWAPs for any period within the last ~9 days.
How to Make Money with Uniswap?
There are two main ways to make money with Uniswap: swapping and providing liquidity.
Swapping is the process of exchanging one token for another at the current market rate, minus a small fee. You can use Uniswap to swap any ERC-20 token on the Ethereum blockchain, such as ETH, DAI, USDC, WBTC, LINK, UNI, and many more. To swap tokens, you need to have an Ethereum wallet that supports web3, such as MetaMask, Coinbase Wallet, or Trust Wallet. You also need to have some ETH and ERC-20 tokens in your wallet to trade. You can then visit the Uniswap app and connect your wallet to it. You will be able to select the token you want to sell and the token you want to buy, enter the amount you want to swap, review the price impact and slippage tolerance, and confirm the transaction. You will then receive the swapped tokens in your wallet.
Providing liquidity is the process of depositing an equal value of two tokens into a pool that facilitates trading between them. For example, if you want to provide liquidity for the DAI/USDC pool, you need to deposit some amount of DAI and USDC into the pool. In return, you will receive liquidity tokens that represent your share of the pool. You will also earn fees from every trade that occurs in your pool, proportional to your share of the total liquidity. The fees are automatically added to the pool, increasing the value of your liquidity tokens over time. To provide liquidity, you need to have an Ethereum wallet that supports web3 and some ETH and ERC-20 tokens in your wallet. You can then visit the Uniswap app and connect your wallet to it. You will be able to select or create the pair you want to join, enter the amount of each token you want to deposit, review the pool share and price range (for v3 pools), and confirm the transaction. You will then receive liquidity tokens in your wallet that you can redeem at any time.
These are the basic steps to make money with Uniswap by swapping or providing liquidity. However, there are also some risks and challenges involved, such as volatility, impermanent loss, gas fees, and smart contract risks. You should do your own research and understand the mechanics and implications of each action before using Uniswap.
