Uniswap is the largest decentralized exchange (DEX) ahead of Curve or 1Inch. It’s an automated platform in decentralized finance (DeFi), offering a revolutionary automated liquidity protocol. As a DEX platform Uniswap works without any regulatory or third party. Its native token UNI makes it possible for its users to “vote” for the platform’s future. Dive into the mechanics of Uniswap, its ease of use, and the role of the UNI token within its ecosystem.

What is UniSwap?

Uniswap runs on Ethereum blockchain, letting users to swap cryptocurrencies. This platform uses smart contracts for automated transactions. Smart contracts are executed automatically when the agreements meet.

This DEX is an open-source platform and anyone can join and use its benefits with an Ethereum wallet, like Coinbase wallet. One of them is the liquidity pools where if you join and stake your tokens you can earn profit. It uses a unique pricing mechanism, the constant product market maker design, which sets prices based on the supply and demand of tokens in each pool.

The last step forward happened in 2021 with the launch of Uniswap V3, an updated swap with innovations like concentrated liquidity and advanced oracles. This led Uniswap as the most popular decentralized exchange.

How Does UniSwap Work?

UniSwap uses a set of decentralized mechanisms: Automated Market Makers (AMM), liquidity pools, and token swapping processes, which together allow trading without requiring traditional market structures.

Automated Market Makers (AMM)

The Automated Market Makers (AMM) presents a mechanism that is similar to traditional market makers found in stocks or centralized exchanges. Traditional market makers realize their profit from the difference between buy and sell prices and must constantly balance their inventory to care liquidity.

Uniswap’s AMM, on the other hand, uses a pre-defined curve, the Constant Product Formula, to automatically define the price based on the relative supply of the token pair in a liquidity pool. This allows independent crypto trading that doesn’t depend on delays or potential conflicts of interest associated with traditional market making. Uniswap’s AMM system is designed to provide consistent liquidity by using liquidity pools.

 Liquidity Pools

Liquidity reserves are really important to the platform’s functionality. These are smart contracts that hold a reserve of two tokens that form a trading pair. Users, or liquidity providers, add the same amount of each token to a pool in exchange for liquidity tokens. These tokens can later be exchanged for the share of the pool, and these users could make some profit by the transaction fees. This system allows Uniswap to offer instant trades to users, with prices defined by the amount of each token in the pool, following the AMM pricing algorithm.

Swapping Tokens

For users looking to trade tokens, the process is simple. You can select the token you want to trade and the one you want to receive. The Uniswap interface then connects to your Ethereum wallet, and now you can execute the swap. The AMM algorithm determines the amount received in the swap, making sure that the trade affects the liquidity pool’s balance minimally.

How to Use UniSwap and the UNI Cryptocurrency?

Using Uniswap is simple, easily accessible even for those new to the DeFi space. With its intuitive interface, users can easily swap tokens, add liquidity, or engage with the platform’s governance through the UNI token.

First-time users of Uniswap will find its interface inviting, with clear instructions for connecting a wallet like MetaMask and initiating a trade. The platform supports numerous ERC-20 tokens, and transactions can be made directly from a user’s wallet without the need to deposit funds into the exchange, maintaining security and control in the user’s hand.


MetaMask is an Ethereum wallet that holds your private keys and provides your digital key to access Uniswaps features. It’s a browser extension and mobile app that let you store and manage account keys, do transactions, send and receive Ethereum-based coins and tokens, and securely connect to decentralized apps (DApps) like Uniswap.

What is UNI Token?

In September 2020, Uniswap launched its UNI token to further decentralize the governance of its protocol. UNI tokens represent more than just another digital asset, as they are a governance token, key to participating in the Uniswap protocol. Token holders can propose, vote on new developments, and help shape the ecosystem.

Furthermore, UNI tokens can be traded or added to liquidity pools, offering users another avenue to engage with the platform and reap the rewards of its DeFi capabilities. When a user decides to buy or sell using Uniswap, traders pay a fee to the pool, which is distributed to liquidity providers.

How to Buy UNI Token?

To buy UNIs is a straightforward process. Follow these steps to add UNI to your portfolio:

  1. Set Up a Wallet: Download and install a digital wallet like MetaMask that supports Ethereum and ERC-20 tokens.
  2. Fund Your Wallet: Purchase Ethereum (ETH) through an exchange and send it to your MetaMask wallet address.
  3. Connect to UniSwap: Visit the Uniswap interface and connect your wallet by clicking the ‘Connect Wallet’ button.
  4. Select UNI Token: The Uniswap protocol allows users to select from various crypto assets without having to worry about the traditional side of the order book. Look for the UNI token by entering ‘UNI’ in the swap interface.
  5. Swap ETH for UNI: Input the amount of ETH you wish to swap for UNI. Be aware that a larger swap means less ETH in the pool, which under the constant product market maker design, raises the price due to the liquidity reserves being altered.
  6. Confirm the Transaction: Review the transaction details, including the gas fee, and confirm the transaction in your wallet.
  7. Transaction Complete: Once the transaction is confirmed on the blockchain, the UNIs will appear in your wallet. While Uniswap introduced a novel concept in the DeFi space, it operates with transparency and is not considered under the purview of securities and exchange regulations, offering a more open financial system for all.
