How to buy carbon credits

To create a listing and sell carbon credits in the Marketplace, you first need to acquire tokens for a specific carbon offset project. There are two ways to do this in Carbonmark:
Buying (redeeming) from a carbon pool
Buying directly from a Marketplace seller
OPTION #1: Buy/redeem from a carbon pool.
Within the Marketplace, find a project you are interested in and click the project card to see the project details.
On the project details page, find the Carbon Pool listing and click "BUY".
On the Buy page, select the quantity of tonnes to purchase.
Click "CONTINUE"

Next confirm the transaction and give permission to the smart contract to transfer tokens on your behalf. Click "APPROVE" and then "NEXT" once the approve transaction completes.
Now click "SUBMIT" to submit the transaction. Note that for both the APPROVE and SUBMIT steps you will need to interact with the wallet you used to login.
When the transaction has completed, you will receive a Purchase Successful message with an option to view transaction on Polygonscan and see your carbon Portfolio.
In your Carbonmark Portfolio page, you will see the carbon token(s) in your list. They are now available to RETIRE or SELL.
OPTION #2: Buy from a seller listing.
Within the Marketplace, find a project you are interested in and click the project card to see the project details.
On the project details page, see if the project has a Seller Listing. If yes, you can click "BUY" to purchase it.
On the Buy page, select the quantity of tonnes to purchase. The available tonnes are shown for reference.
Based on the quantity entered, the listing cost will be updated. If the form entries are correct, click "CONTINUE".
Next confirm the transaction and give permission to the smart contract to transfer tokens on your behalf. Click "APPROVE" and then "NEXT" once the approve transaction completes.
Now click "SUBMIT" to submit the transaction. Note that for both the APPROVE and SUBMIT steps you will need to interact with the wallet you used to login.
When the transaction has completed, you will receive a Payment Successful message, with an option to view the transaction on the blockchain (polygonscan). Click "VIEW YOUR ASSETS" to return to your Portfolio page.
