The world of digital ownership has evolved dramatically with the rise of NFTs (Non-Fungible Tokens), and OpenSea stands at the forefront as the leading marketplace for creators and collectors. Whether you're in Taiwan or anywhere else globally, this comprehensive guide walks you through everything you need to know—from what NFTs are, to setting up your wallet, buying your first digital collectible, and even listing your own NFT for sale.
Designed for absolute beginners, this step-by-step tutorial ensures you can start trading on OpenSea in under five minutes—with no prior blockchain experience required.
What Are NFTs?
NFT stands for Non-Fungible Token, a unique digital asset verified using blockchain technology. Unlike cryptocurrencies such as Bitcoin or Ethereum (which are fungible and interchangeable), each NFT is one-of-a-kind. This uniqueness makes them ideal for representing digital art, music, videos, virtual real estate, gaming items, domain names, and more.
Because NFTs are stored on a decentralized ledger (primarily the Ethereum blockchain), ownership is transparent, secure, and tamper-proof. Artists and creators benefit from built-in royalties, ensuring they earn a percentage every time their work is resold—a game-changer in the creative economy.

Why OpenSea Is the Top NFT Marketplace
OpenSea is the world’s largest peer-to-peer NFT marketplace, offering users the ability to buy, sell, and mint NFTs across multiple categories:
- Digital art
- Collectibles
- Virtual worlds
- Domain names
- Gaming items
One of OpenSea’s biggest advantages is its accessibility. There's no invitation needed—anyone can create an account by simply connecting a cryptocurrency wallet like MetaMask. You don’t pay to list NFTs; fees only apply when you complete a transaction (such as purchasing or selling an item), which includes gas fees and a small service fee.
With support for multiple blockchains including Ethereum, Polygon, and Solana, OpenSea continues to expand its ecosystem while maintaining ease of use for newcomers.
According to DappRadar, OpenSea has surpassed $10 billion in total trading volume, far outpacing competitors like Axie Infinity and CryptoPunks. Its user-friendly interface and robust security features make it the go-to platform for both casual users and serious investors.
How to Get Started on OpenSea: Step-by-Step Guide
To begin trading on OpenSea, you’ll need three things:
- A cryptocurrency exchange account (to buy ETH)
- A crypto wallet (to store your funds)
- An OpenSea account (linked via your wallet)
Let’s walk through each step.
Step 1: Sign Up on a Cryptocurrency Exchange
Before entering the NFT space, you’ll need Ethereum (ETH)—the primary currency used on OpenSea. In Taiwan, one of the most trusted platforms for buying ETH with TWD is MAX Exchange, known for its high liquidity, simple interface, and strong regulatory compliance.
While we won’t include external links, you can easily find MAX Exchange by searching online. Once registered:
- Complete identity verification (KYC)
- Deposit TWD via bank transfer
- Purchase ETH directly
After buying ETH, you’re ready to transfer it to your personal wallet.
Step 2: Set Up MetaMask Wallet
MetaMask is a free, browser-based cryptocurrency wallet that allows you to interact securely with the Ethereum blockchain—and by extension, OpenSea.
Here’s how to set it up:
- Go to the official MetaMask website and download the extension for Chrome, Firefox, or mobile.
- Click “Create a Wallet.”
- Agree to the terms.
- Create a strong password (minimum 8 characters).
- Write down your 12-word recovery phrase—this is critical. Never share it or store it digitally.
- Confirm your recovery phrase.
- Your wallet is now ready!
Once installed, copy your wallet address and send ETH from MAX Exchange to this address. Transaction times vary but typically take just a few minutes.

Step 3: Connect MetaMask to OpenSea
Now that you have ETH in your wallet, it’s time to visit OpenSea.io, the official website.
Here’s how to link your wallet:
- Navigate to OpenSea.io
- Click the wallet icon in the top-right corner
- Select MetaMask from the options
- Confirm the connection in your MetaMask extension
- You’re now logged in!
Note: OpenSea doesn’t require traditional registration—you automatically get a profile once your wallet is connected.
How to Buy Your First NFT on OpenSea
Once connected, browsing and buying NFTs is straightforward:
- Use the search bar to look for collections (e.g., "PhantaBear")
- Filter by price, rarity, or traits
- Click on an NFT you like
- Click “Buy Now” or place a bid
- Confirm the transaction in MetaMask
The purchase will take 1–2 minutes depending on network congestion and gas fees. Once confirmed, the NFT appears in your OpenSea collection.
Famous examples include:
- Jay Chou’s Phanta Bear, which sold out in 40 minutes and generated over $57 million in secondary sales.
- Influencer Saint Chen selling 38 NFTs of his video clips in 24 hours, earning nearly 4.7 ETH (~NT$490,000).
- Artist collaborations and music-based NFTs gaining traction across Asia.
These cases highlight how creators are monetizing digital content like never before.
How to Sell an NFT on OpenSea
Want to turn your digital creation into income? Here’s how to list your own NFT:
- Log into OpenSea and click your profile picture
- Select “My Collections” or upload a new item
- Click “Create” to mint your file (image, video, audio)
- Fill in details: name, description, properties
- Under “Supply,” choose whether it’s a single item or multiple copies
- Click “Create” again to finalize minting (requires gas fee)
- After creation, go to your item and click “Sell”
- Set a fixed price or auction duration
- Choose payment token (usually ETH)
- Review and confirm the listing in MetaMask
You can also set a creator royalty (typically 5–10%), meaning you’ll earn a cut every time your NFT is resold—a powerful long-term earning model.
