What is Uniswap? Why is it useful?

Large exchanges such as Binance and Coinbase may be among the best exchanges for buying and selling cryptocurrencies. But Uniswap has features that set it apart from other exchanges. What is this exchange and what are its features? How can you use Uniswap and on what platform is it running? In this article, we will review all the features and facilities of the Uniswap exchange.

What is Uniswap?

Uniswap is a decentralized exchange that was launched in 2018. In this exchange, you do not need to provide your cryptocurrencies to the exchange and wait for someone to buy. In fact, Uniswap uses a new type of trading model called automated liquidity protocol. This protocol, launched on Ethereum, is used for swapping ERC20 tokens. With this protocol, you no longer have to wait for the other party to trade and any trade is done immediately (with the specified price). Uniswap is compatible with MetaMask and MyEtherWallet wallets.

How Uniswap works?

This exchange is executed with an exchange and factory contract.

  • The factory smart contract is used to add new tokens
  • Exchange contract facilitate token swaps

The open-source nature of this exchange allows anyone to copy code for decentralized exchanges. Also, with the Constant Product Market Maker Model feature, the user can list tokens for free in this exchange. A new Uniswap smart contract and liquidity pool must also be created for the token. This requires very high fees in centralized exchanges. To start the liquidity pool, whenever a person adds a new ERC-20 token to an additional exchange, he must add a certain amount of the selected ERC-20 token, and an equal amount of another ERC-20 token.
