Steps to Buy NFT at OpenSea

Once you have registered with OpenSea and have linked your meta mask, you will be able to purchase NFTs.

However, to purchase NFTs, you need ETH (Ethereum), a crypto asset that matches the price of NFTs.

There are following 3 steps to purchase an NFT.

STEP①Open a crypto asset exchange account

In order to purchase NFTs at Onpensea, you must have crypto assets.

Crypto assets are bought on dedicated exchanges, so first open an account on an exchange.

STEP②Purchase ETH & MetaMask remittance

Once you have opened an account, you can purchase Ethereum (ETH) and send it to Metamask.

STEP③ Search NFTs in OpenSea

Once the transfer of crypto assets is completed, you will finally be able to purchase NFTs.

OpenSea’s two NFT purchase options

Once you have registered with OpenSea and have enough money to buy into MetaMask, you can purchase NFTs at any time.

Let us explain in detail about “regular purchases” and “auction purchases”.

(1) Regular purchase

First, let us explain how to make a regular purchase.

The regular purchase is to buy the NFT at the price quoted, but you will need to pay the NFT price and a fee called the “gas fee” when you make your purchase.

We have indicated that there are two ways to make a regular purchase, and the main ways are as follows

In addition, a regular purchase can be accompanied by an “offer order,” in which the buyer offers the amount at which he/she wants to buy.

*Offer orders and auction purchases use WETH (Wrapped Etherium) instead of regular ETH.
How to exchange WETH will be explained later.

❶ Buy on the spot

First, tap “Add to Cart” on the NFT you want to buy, then check the cart in the upper right corner.

When you tap the cart, you will see the picture below. Please make sure that the NFT you want is the correct one and tap “Complete Purchase”.

You can also “Buy Now” by hovering over the ⚡ next to “Add to Cart”.

❷ When offering the asking price

First, tap “Make Offer”.

When the following screen appears, enter the desired amount (WETH) and tap “Make Offer”.

After an offer is made, the transaction is concluded if the seller accepts the amount requested.

These are the descriptions of “regular purchases”.

(2) Auction Purchase

There are two main types of auction purchases: English Auction and Dutch Auction.

Difference between “English Auction” and “Dutch Auction

What is English Auction?
An auction format where the highest bidder gets the right to buy, with the price going up.

What is Dutch Auction?
An auction format in which the price goes down until a bidder appears.

Here we will explain “English Auction” in which the person who submits the highest order by the bidding deadline wins (purchases) the auction.

Don’t worry, auction purchases are not difficult.

First, tap “Bid” on the screen below.

Next, when you get to the “Bid” screen below, enter the desired amount and tap “Bid”.

By the way, you can check if you are able to participate on the screen below.

The above is the “Auction Purchase” process.

How to obtain the “WETH” needed for the English Auction

Finally, we will show you the procedure for exchanging ETH for “WETH” (also known as Wrapped Ether / “Red Ether”), which is required for OpenSea auction bidding.

Note here that there is a fee known as the “gas fee”.

The exchange rate for WETH is “1 ETH = 1 WETH”, but this gas fee will require extra ETH.

Now, let us show you how to actually exchange the money into “WETH”.

How to exchange to WETH

First, open Metamask, and make sure that the wallet contains ETH.

After confirming that you have the required amount of ETH, tap “Swap”, enter the amount to be exchanged, and select “WETH” as the swap destination.

When you have entered the amount and “WETH”, tap “Check Swap”, confirm the fees, and then tap “Swap”.

When you see the screen on the lower left, the swap is complete. Please return to your meta mask and confirm that “WETH” is reflected.

Things to keep in mind when using Opensea

Were you able to find & purchase the NFT you were looking for?

Finally, here is a summary of what you need to keep in mind when purchasing NFTs at Opensea.

Watch your ETH gas fee!

Ethereum (ETH) is notorious for its high gas fees.

The gas bill is not fixed and depends on the volume of ETH transactions at the time, so you need to check your balance every step of the way to make sure you don’t run short! You need to check your balance every step of the way to make sure that you don’t run out!

If you want to adjust the gas cost yourself, turn on “Advanced Settings” in the meta mask.

When you actually purchase the NFT, Metamask will pop up to confirm the gas fee, at which point you will press the “EDIT” button.

Max priority fee is mainly changed. (Max fee is automatically converted when Max priority is changed.)

To find out how much you should pay for gas fee, let’s use ETHgas fee checker.

On the other hand, setting the gas price too low can delay the transaction and make it more likely to fail, and can also result in unnecessary costs due to gas alone, so it is recommended that gas price adjustments be made only after you are familiar with the gas price.

Beware of stranger NFT!

When you register with Onpensea, you will be able to view the collections you have purchased.

You can actually see the NFTs you have by accessing your profile page…

Especially for NFTs that are in the “hidden” category, be aware that other NFTs may also be stolen if they are set to “visible”.
