QuickSwap, a division of Uniswap running on the Polygon network, is a layer 2 scaling solution for Ethereum. It has lower transaction fees with respect to Ethereum's main network, where token exchanges are at a lower price compared to exchanges like Uniswap.

QuickSwap is a set of smart contracts that allows people to send orders to buy or sell cryptocurrencies through their browser without the need to register or provide personal information. A smart contract is a computer program that is executed by the Ethereum Virtual Machine (EVM). Smart contracts manage token exchanges, and not a person or entity.

If you want to know how to use and buy in quickswap, follow all the steps of the guide behind. You will learn how to buy in quickswap without making mistakes.

1. First we access the QuickSwap website, and then we connect our wallet by clicking on "Connect to a wallet" and choose the wallet we will use to buy, in our case MetaMask. You will see a window where we will choose the account where we will use the funds we are going to trade with. Once you have done this, go to the next step and click on “Connect”.
2. MATIC will appear by default and we will choose the currency we are going to buy by clicking on "Select a token". If you want to use a different token as a base, click on "MATIC" and choose your option.
3. Once we have chosen the currency we will buy, we set the amount of MATIC we will use to buy it, remember that we cannot use all of it because we will need MATIC to finish some operations. Then click on "Swap" and the final information of the coins we are going to receive will appear and then we must click on "Confirm Swap".
4. You will see a MetaMask window where you will see the Polygon commission you will pay and the total amount of the operation including the gas. When we click on "Confirm" a window will appear and we will wait for the miners to confirm the operation and for the coin we have bought to appear in our wallet. To do this, click on "View on Block Explorer" and you will be able to see the details of the operation.
