Q & A

What is Uniswap?

Uniswap is a decentralized, permissionless exchange built on the Ethereum network that allows users to trade Ethereum ERC-20 tokens directly without the need for a middleman or centralized authority.

How does Uniswap differ from traditional cryptocurrency exchanges?

Uniswap differs from traditional exchanges by being decentralized, meaning it operates without a controlling company or centralized servers. It also doesn't require users to go through KYC (Know Your Customer) processes, and it allows users to maintain control over their funds by trading directly from their own wallets.

What is the UNI token?

The UNI token is a governance token introduced by Uniswap through an airdrop in September 2020. It allows holders to influence and vote on development decisions related to the Uniswap platform.

How does liquidity work on Uniswap?

Liquidity on Uniswap is provided through liquidity pools, which are shared pots of funds deposited by the public. Liquidity providers (LPs) receive a portion of the trading fees in a process known as liquidity mining.

What is the 'Constant Product Market Maker Model'?

The 'Constant Product Market Maker Model' is an Automated Market Maker (AMM) used by Uniswap to determine the price of coins on its platform. It follows the formula X * Y = K, where X and Y are the amounts of the two tokens being traded, and K is a constant value.

How does slippage occur on Uniswap?

Slippage occurs on Uniswap because each trade is an Ethereum transaction that takes time to be broadcasted and confirmed by the Ethereum network. During this time, the price of the token may change, resulting in the executed price differing from the price at the time the order was placed.

Why is it important to do your own research when trading on Uniswap?

It's important to do your own research when trading on Uniswap because, unlike traditional exchanges, Uniswap does not conduct extensive due diligence on the tokens listed. This means that there may be scam coins listed, and the onus is on the user to determine the legitimacy and value of a token.

What are the benefits of using a decentralized exchange like Uniswap?

Benefits of using Uniswap include not having to go through KYC processes, maintaining full control over funds, and the ability to trade a wide variety of ERC-20 tokens. It also provides a higher degree of privacy and censorship resistance compared to centralized exchanges.

How has the UNI token's value changed since its introduction?

Since its introduction through an airdrop in September 2020, the UNI token's value has risen substantially. This increase reflects the perceived future value of Uniswap and the desire of investors to participate in its governance.

What are the different versions of Uniswap that have been released?

Uniswap has released three main versions: V1 in November 2018, which allowed trading of any ERC-20 token to Ether; V2 in May 2020, which enabled direct trading of ERC-20 tokens without the need for Ether; and V3 in May 2021, which introduced more capital efficiency and lower trading costs.

Why is liquidity important for an exchange?

Liquidity is crucial for an exchange because it determines how easily buyers and sellers can find a match and execute trades. High liquidity ensures that trades can be completed quickly and at a fair market price, which is essential for the health and functionality of the exchange.

How does the 'Slippage' tolerance setting work on Uniswap?

The 'Slippage' tolerance setting on Uniswap allows users to set a limit on how much the price can change from the time the order is placed to when it is executed. If the price change exceeds the set tolerance, the order is automatically canceled, protecting users from unfavorable price movements during transaction confirmation.
