Why is permission required in PancakeSwap?

With so many people eager to jump on the cryptocurrency bandwagon, platforms like PancakeSwap have quickly grown in popularity. PancakeSwap is a decentralized exchange that allows users to trade tokens. It is built on the Binance blockchain and therefore requires certain protocols to run in order for trades to take place. This is where the approval mechanism comes into play. If you are wondering why it is necessary to approve tokens and transactions on PancakeSwap, read on. This article tells you everything you need to know about the process.

Why do I need to approve PancakeSwap?

A decentralized exchange (DEX) allows crypto traders to conduct transactions without intermediaries. You can swap one token for the next without having to deal with order books. PancakeSwap relies on having a well-funded liquidity pool to facilitate these trades. Users place their funds in a central location (pool of liquidity) from which others draw the tokens they need. Therefore, a trade does not have to be a one-to-one exchange with another user.

PancakeSwap is based on an Automated Market Maker (AMM). An AMM is a protocol that automates the trading process and eliminates the need for a central exchange. Instead of using order books to match trades, this system uses smart contracts to price tokens and provide liquidity. When you place tokens on PancakeSwap, they are essentially bound by a smart contract. This contract makes them available for trading within the liquidity pool.

The smart contract needs access to your crypto wallet for a trade to take place. Approvals are protocols established as industry standards. They prevent smart contracts from accessing your funds without your permission. Because of this, PancakeSwap requires permits. You give smart contracts permission to trade your assets.

Let’s take a closer look at PancakeSwaps smart contracts.

What is a smart contract on PancakeSwap?

A smart contract is a program to automatically enforce an agreement. It is triggered after certain conditions are met. For example, if a buyer and seller agree to trade a certain number of goods at a certain value, a smart contract can be set up with the terms of that agreement. As soon as the seller provides the goods, the smart contract takes effect and transfers the money to the seller’s account. This method ensures that no party is left out.

Smart contracts on PancakeSwap verify trading conditions, including token price definition. This eliminates the need for a third party to perform this function. The smart contract requires access to the tokens, and therefore your crypto wallet, for swaps to take place. You only need to grant this permission once for each token.

Types of Smart Contracts on PancakeSwap

Because PancakeSwap is built on top of an AMM, multiple different contracts need to be approved when trading on the platform. Let’s take a look at some of them here.

add liquidity

Liquidity pools are at the heart of how PancakeSwap works. By adding liquidity, you increase the number of tokens available for trading. Here’s how.

To add liquidity, you need to commit two pairs of tokens. You will basically trade one token for another.

1. Open PancakeSwap in your browser
   
2. Hover over ‘Trade’ and click on Liquidity.
   
3. Tap on “Add Liquidity” and then scroll down to the “Input” section.
   
4. Press “Choose Currency” and select the token you wish to deposit.
   
5. Go to the “Issue” section, click on “Select Currency” and select the second token you wish to deposit.
   
6. Go back to “Input” and enter the token amount you wish to trade.
   
7. The “Output” category is then filled in automatically.
   
8. Tap the “Enable Cake” button at the bottom of the screen.
   
9. In your crypto wallet, click on the “Confirm” pop-up message.
10. Tap “Supply” and confirm the transaction again with your crypto wallet.
    

Your new LP (Liquidity) Token balance will be displayed at the bottom of the screen.

Clicking the confirm button during this process will run the smart contract required to add liquidity to PancakeSwap. It allows the platform to access funds from your crypto wallet.

Mark out

Once you have received your LP tokens through the liquidity pool, you can now use them to earn returns. Staking means holding these coins in specific pools or farms and storing them there until they earn interest.

PancakeSwap charges a 0.25% transaction fee, of which 0.17% is returned to the liquidity pools. It is distributed among liquidity holders and gives them an incentive to add their funds to the platform. This is the money you earn by wagering your tokens. To stake tokens at PancakeSwap, follow the steps outlined below.

1. Navigate to the Farms section and select the token you wish to stake.
   
2. In the pop-up message that appears, tap “Approve Contract” to confirm that you agree to the transaction and the fee shown.
3. Select the amount you wish to wager and press “Confirm”.

To stake crypto on PancakeSwap, you need to approve the smart contract that gives access to your funds.

Giving permission

PancakeSwap is a decentralized platform built on top of an automated market maker. This system uses smart contracts to facilitate cryptocurrency trading. In order for these contracts to be executed, platform users must approve the transactions. This gives PancakeSwap access to their cryptocurrency wallets, making trading possible. Therefore, approval is required on the platform as this gives PancakeSwap permission to conduct transactions.
