USDT (USD Tether) has become one of the most widely used dollar-pegged stablecoins in the cryptocurrency ecosystem. Known for its price stability and broad acceptance, USDT serves as a critical bridge between traditional finance and digital assets. Backed 1:1 by reserves including U.S. dollars and other liquid assets, USDT maintains a consistent value of approximately $1, making it ideal for trading, saving, and transferring value across blockchains.
Issued by Tether Limited, USDT operates across multiple blockchain networks such as Ethereum, Tron, Solana, Binance Smart Chain (BSC), and Algorand. This multi-chain functionality enhances its utility, allowing users to move funds efficiently depending on network speed and cost. Whether you're a beginner entering crypto or an experienced trader managing portfolios, understanding how to buy, swap, and transfer USDT is essential.
How to Buy USDT
Buying USDT is simple and accessible through major cryptocurrency platforms like OKX. You can purchase USDT using fiat currencies (like USD or EUR) via various payment methods, including bank cards, P2P trading, Apple Pay, and Google Pay.

Note: Available options vary by country. Some regions may only allow P2P purchases due to local regulations.
How to Swap USDT
Swapping USDT allows you to convert it into other cryptocurrencies or stablecoins quickly. This can be done on centralized exchanges like OKX or through decentralized finance (DeFi) platforms directly from your wallet.
Swapping USDT on OKX Web Platform
- Log in to your OKX account and ensure you have USDT in your balance.
- Go to “Trade” > “Convert” (for instant swaps) or use “Spot” trading for limit orders.
- Set “From” to USDT and choose your desired token in the “To” field.
- Enter the amount of USDT you wish to swap; the output amount updates automatically.
- Click “Convert”—your new asset will appear in your wallet immediately.
Swapping USDT Using the OKX Mobile Wallet
- Open the OKX app and go to the Wallet section.
- Tap “Trade” > “Swap.”
- Select the blockchain where your USDT resides, then set From: USDT, and choose your target token.
- Input the amount and review the estimated return.
- For first-time swaps, tap “Approve USDT” to authorize the transaction, then hit “Swap.”
You can adjust slippage tolerance or routing preferences, but default settings work well for most users.
Swapping USDT on DeFi Platforms
For greater control and privacy, you can swap USDT directly from your wallet using decentralized exchanges (DEXs). However, consider these factors:
- Network fees (gas costs) can be high on congested chains like Ethereum.
- Slippage may affect trade execution during volatile markets.
- Only tokens supported on that specific blockchain are available for swapping.
To optimize rates and reduce costs, use an aggregator like the OKX DEX aggregator, which pulls liquidity from over 70 DeFi platforms.
