How to Buy NFT Art

About NFT purchase

Here, I will briefly explain the following two points.

• The flow to purchase the works exhibited on the Ethereum blockchain.
• The flow to purchase the works exhibited on the Polygon blockchain.

(This explanation is for “OpenSea”)

Cryptocurrency is required to purchase NFT art.

Cryptocurrency	How to get	Blockchain	NFT art of “Mr.Paas”
“ETH”	Buy on Cryptocurrency Exchanges, etc.	Ethereum (regular sales)
“WETH“	ETH to WETH swap	Ethereum (auction, offer)
“WETH(polygon)”	ETH to WETH (polygon) swap MATIC to WETH (polygon) swap	“Polygon”

• “ETH” is required to purchase Ethereum works (regular sale).
• “WETH” is required to purchase Ethereum works (auctions, offers).
• “WETH(Polygon)” is required to purchase Polygon works.

④ Polygon (Pattern B: When MATIC cannot be purchased in its own currency)

Flow A (low gas fee) ☆Recommended!

	Home Currency	Buy MATIC
Cryptocurrency Exchanges “B”	a◯	a✕
Cryptocurrency Exchanges “C”	a✕	a◯

Process

a1 ,	Create a Cryptocurrency Exchanges “B” account to purchase Ethereum(ETH).
a2 ,	Buy Ethereum(ETH).
a3 ,	Create a Cryptocurrency Exchanges “C” account (to convert Ethereum (ETH) to MATIC).
a4 ,	Transfer Ethereum from Cryptocurrency Exchanges “B” to Cryptocurrency Exchanges “C”.
a5 ,	Convert Ethereum(ETH) to MATIC on Cryptocurrency Exchanges “C”.
a6 ,	Prepare Cryptocurrency wallets and connect cryptocurrency wallets to your Polygon network.
a7 ,	Transfer MATIC from the Cryptocurrency Exchanges “C” to the Cryptocurrency wallets.
a8 ,	Swap from MATIC to WETH(Polygon) using Cryptocurrency wallets‘s swap function.

Summary

In this article, I explained which cryptocurrency should be prepared to purchase works at OpenSea.

We also explained how to obtain cryptocurrencies ETH, WETH, and WETH (polygons).

For those who purchase NFT art for the first time, trading on the blockchain may be a little difficult to understand.

Blockchain is often compared to a country.

For example, you need Japanese yen to shop in Japan and pounds to shop in the UK.

Similarly, to shop on the Ethereum blockchain, you need the cryptocurrency “ETH”.

To shop on the Polygon blockchain, you need the cryptocurrency “WETH (polygon)”.

Isn’t it a little easier to understand if you think so?

The “MATIC” required to obtain WETH (polygons) may not be available for purchase on your country’s cryptocurrency exchange.

Even in that case, you can save fees (gas fees) by obtaining MATIC through cryptocurrency exchanges in other countries.

(See “Polygon (Flow A of pattern B)”)

Please get your favorite NFT art by all means.

We look forward to your continued support of “Mr.Paas NFT”.
