Decentralized Finance (DeFi) has revolutionized how people earn returns on their digital assets. With the rise of blockchain technology and the growing popularity of cryptocurrencies like Bitcoin and USDT, more users are stepping beyond centralized exchanges and exploring the world of yield farming, liquidity pools, and on-chain finance.
If you're new to this space, the vast amount of information can feel overwhelming. But don’t worry — this guide breaks down everything into four clear, actionable steps to help you go from fiat currency (like TWD) to actively earning rewards through DeFi liquidity mining — all while leveraging low-cost networks like Polygon (MATIC).
By the end of this article, you’ll understand how to:
- Convert TWD into crypto
- Set up a self-custody wallet
- Transfer funds efficiently across exchanges and chains
- Participate in a real liquidity pool on platforms like Balancer
Let’s dive in.
Step 1: Enter the Crypto World — Convert TWD to USDT
Just like using TWD to buy stocks, your first move into blockchain starts with converting fiat into a widely accepted cryptocurrency. The most practical entry point is USDT (Tether), a stablecoin pegged 1:1 to the US dollar, making it ideal for trading and DeFi activities.
One of the most trusted exchanges in Taiwan for TWD-to-crypto conversion is a regulated local platform that supports direct bank transfers via ATM, online banking, or mobile banking apps. After signing up and completing identity verification — a crucial step for security and compliance — you can deposit TWD directly into your account.
Once your funds are in, head to the trading section and purchase an equivalent amount of USDT (ERC20 or TRC20). Congratulations — you’ve taken your first step into the decentralized ecosystem!

💡 Why USDT?
USDT combines price stability with broad blockchain compatibility, making it perfect for beginners entering DeFi without exposure to extreme volatility.
Step 2: Set Up Your Web3 Wallet
To interact with DeFi protocols, you need a non-custodial wallet — a personal key to the decentralized world. The most popular choice is MetaMask, often called the "fox wallet" due to its logo.
Installing MetaMask is simple:
- Download the browser extension or mobile app.
- Create a new wallet and securely back up your recovery phrase — never share this with anyone.
- Once set up, you’ll see your wallet address and balance.
But here’s a pro tip: To save on transaction fees, we recommend adding the Polygon (MATIC) network to your wallet. Polygon is an Ethereum scaling solution that offers faster transactions and significantly lower gas costs.
How to Add Polygon (MATIC) Network to MetaMask
- Open MetaMask and click on the network dropdown.
- Select “Custom RPC” at the bottom.
Enter the following details:
- Network Name: Matic Mainnet
- New RPC URL:
https://rpc-mainnet.matic.network - Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL: https://explorer.matic.network/
- Click “Save.” You’re now connected to Polygon!
This setup prepares you for low-cost DeFi interactions — essential when swapping tokens or providing liquidity.
Step 3: Move Funds Smartly — From Exchange to Wallet
Now that you hold USDT, it’s time to move it toward DeFi. However, directly withdrawing USDT from a local exchange to MetaMask can be expensive due to Ethereum network fees. Instead, use a cost-effective bridge strategy:
Efficient Transfer Path:
Send USDT via TRC20 to a global exchange
- Choose a network with low withdrawal fees (e.g., TRC20).
- Withdraw your USDT from the local exchange to your account on a major international exchange.
Buy MATIC on the global exchange
- Use your USDT to purchase MATIC, the native token of Polygon.
Withdraw MATIC to your MetaMask wallet
- When withdrawing, select the Polygon (MATIC) network.
- Transaction fee: typically just 0.1 MATIC — extremely affordable.
This method minimizes costs while ensuring fast, reliable transfers. Always test with a small amount first to confirm address accuracy.

⚠️ Critical Reminder:
Never send funds to an unsupported network. Always double-check the withdrawal network (e.g., Polygon vs. Ethereum) to avoid permanent loss.
Step 4: Join a Liquidity Pool on DeFi Platforms
With MATIC in your wallet, you're ready for the exciting part — liquidity mining.
We’ll use Balancer, a leading automated portfolio manager and liquidity protocol available on multiple chains including Polygon.
Getting Started on Balancer
- Visit balancer.fi and connect your MetaMask wallet.
- Switch the network to Polygon using the top-left dropdown menu.
You’ll now see various liquidity pools, each showing:
- Total value locked (TVL)
- 24-hour trading volume
- Annual percentage yield (APY)
- Token composition
Understanding Liquidity Mining Rewards
Returns come from two sources:
- Trading fees generated by trades within the pool
- Incentive rewards (often paid in platform tokens like BAL)
Keep in mind: providing liquidity carries risks, especially impermanent loss, which occurs when token prices diverge significantly after you deposit.
Example: Deposit into WMATIC/USDC/WETH/BAL Pool
- Click Trade at the top.
- Swap some of your MATIC for WMATIC (wrapped MATIC).
🔔 Pro tip: Keep a small reserve of MATIC in your wallet — it’s needed to pay gas fees on Polygon. - Go to Invest, select the WMATIC/USDC/WETH/BAL pool.
- Enter the amount of WMATIC you want to deposit.
- Confirm the transaction in MetaMask.
After confirmation, you’ve officially become a liquidity provider — earning passive income from both fees and reward tokens!
Frequently Asked Questions (FAQ)
Q1: What is liquidity mining?
Liquidity mining involves depositing crypto assets into a decentralized pool to facilitate trading or lending, in return for earning rewards such as trading fees and governance tokens.
Q2: Is liquidity mining risky?
Yes. Key risks include impermanent loss (due to price volatility), smart contract vulnerabilities, and changing APYs. Always research pools and start with small amounts.
Q3: Why use Polygon instead of Ethereum?
Polygon offers much lower transaction fees and faster processing times compared to Ethereum’s mainnet, making it ideal for frequent DeFi interactions.
Q4: Can I lose money in DeFi?
Yes. While returns can be high, risks include market fluctuations, protocol bugs, and user errors (like sending funds to wrong addresses). Education and caution are vital.
Q5: How do I track my DeFi earnings?
Use portfolio trackers like Zapper or Zerion, which sync with your wallet and display balances, yields, and historical performance across multiple protocols.
Q6: Do I need a lot of money to start?
No. Many platforms allow deposits starting from just a few dollars. However, very small amounts may not generate meaningful returns after accounting for gas and slippage.
Final Thoughts
Entering the world of DeFi doesn’t have to be complicated. With just four steps — converting fiat, setting up a wallet, transferring funds wisely, and joining a liquidity pool — you can begin earning yields on your crypto assets.
The key is starting small, learning continuously, and using secure, low-cost networks like Polygon to maximize efficiency.
👉 Start exploring high-yield DeFi opportunities with confidence.
By mastering these fundamentals, you’re not just investing in crypto — you’re becoming part of a decentralized financial future.
