What is Uniswap? A tutorial on how to use the decentralized exchange Uniswap

When we talk about decentralized exchanges (DEX), Uniswap is undoubtedly one of the leaders. As a key player in the cryptocurrency space, Uniswap provides an intermediary-free way to trade directly on the blockchain, allowing users to exchange various crypto assets securely and easily. Today, let's dive into what Uniswap is and how it operates on this platform to help you get the hang of this decentralized exchange.

What is Uniswap?

Uniswap is an ethereum blockchain-based decentralized exchange (DEX) designed to allow users to trade cryptocurrencies without the need to trust a third party. It utilizes Automated Market Maker (AMM) technology to replace the traditional order book system. On Uniswap, you don't need to find a counterparty to make a trade, as the system performs price calculations and trade execution based on a Liquidity Pool.

One of the core features of Uniswap is that it is decentralized, meaning it is not controlled by a single company or organization, which not only increases security but also makes the trading process more transparent. On Uniswap, your money is always in your hands and all transaction records are publicly available on the blockchain.

How Uniswap works

The Automated Market Maker (AMM) mechanism used by Uniswap enables trading through liquidity pools. Unlike traditional order book exchanges, trading on Uniswap is supported by user-provided liquidity pools that contain two or more types of assets. For example, if you want to trade Ether (ETH) and the stable currency USDT, the liquidity pool will contain both assets.

When you trade on Uniswap, the system calculates the trade price based on the percentage of the liquidity pool and automatically completes the trade. Each trade is charged a handling fee that is distributed to the user who funds the liquidity pool, which allows the user who provides the liquidity to earn passive income.

How to use Uniswap for transactions

Before you start using Uniswap, you will first need to prepare an Etherwrap wallet (such as a MetaMask or Coinbase Wallet). These wallets will be used to store your crypto assets as well as make transactions.

1. Connect Wallet: Once you are on the official Uniswap website, click the "Connect Wallet" button in the upper right corner, select your wallet and complete the authorization.
2. Select Pair: In Uniswap's trading interface, you can choose which tokens you want to exchange. Usually Ether and stablecoins (e.g. USDT) are the most common trading pairs.
3. Setting up the number of transactions: Enter the number of tokens you wish to exchange and Uniswap will automatically calculate the number of tokens you will receive. Remember to keep an eye on the handling fee, which will be shown in the transaction details.
4. Confirmation of transactionsCheck all the details and click "Swap" to proceed with the transaction, then confirm the transaction and pay a certain amount of EtherNet (Gas Fee).

After the transaction is complete, you can view the new token asset in your wallet.

How to Provide Liquidity and Earn Income

In addition to trading, Uniswap also allows users to offer liquidity and earn from it. Providing liquidity is a form of passive income, where you add funds to a liquidity pool and earn a percentage of the assets in the pool.

1. Select Liquidity PoolFirst of all, you need to choose a liquidity pool that you are willing to fund. Generally, liquidity pools on Uniswap consist of two different crypto assets, such as ETH and USDT.
2. Add Fluidity: When you have selected a liquidity pool, deposit your assets into that pool. The system will automatically ask you to provide two assets based on the ratio in the pool to maintain the balance of the pool.
3. Get Transaction FeeUniswap's transaction fee is 0.3%, of which 0.25% is allocated to the liquidity provider.

The advantage of providing liquidity is that you can earn additional income through these fees. However, it is important to note that the value of the assets in the liquidity pool will change as the market fluctuates, which can create a profit and loss risk.

Risks and Precautions of Uniswap

While Uniswap offers a convenient and decentralized way to trade, there are some risks that users should be cautious of.

1. Price Slippage: Since Uniswap trades are based on liquidity pools, price slippage may occur when the market is more volatile, which may result in the actual transaction price deviating from the expected price.
2. Impermanent Loss: If you provide liquidity and place two assets in a pool, your funds may face extraordinary losses when the price of those assets fluctuates widely. This is because when the price of one of the assets goes up or down, the liquidity pool automatically adjusts the ratio of the assets, which may result in a loss.
3. Smart Contract Risks: Although Uniswap's smart contracts are audited, there is still a risk that they could be compromised or vulnerable. Therefore, it is important to choose a reputable decentralized exchange and carefully examine the smart contracts.

Frequently Asked Questions Q&A

1. How can I minimize the impact of price slippage?
You can set a reasonable slippage tolerance so that the system will automatically cancel a trade if the price fluctuates beyond a certain range during the course of the trade. This will help you avoid losses due to large fluctuations.

2. How can I view my earnings after liquidity is provided?
You can view your earnings, which are accumulated in the form of tokens, in Uniswap's Liquidity Pool screen. You can also choose to withdraw or re-enter your earnings into the liquidity pool.

3. How to choose the most suitable trading pair?
When choosing a pair, you should consider the liquidity of the market and the stability of the token. Common pairs such as ETH/USDT or DAI/USDT usually have higher liquidity and therefore lower transaction costs.
