Stablecoins have revolutionized the way users interact with digital assets, and among them, USDT (USD Tether) stands out as one of the most widely adopted. As a U.S. dollar-pegged cryptocurrency, USDT offers stability in an otherwise volatile market, making it a go-to choice for traders, investors, and blockchain users worldwide.
Issued by Tether Limited, USDT is backed by reserves intended to match its circulating supply, maintaining a 1:1 value with the U.S. dollar. This stability, combined with its multi-chain availability—on networks like Ethereum, Tron, Solana, BSC, and Algorand—makes USDT an essential tool for trading, saving, and transferring value across the crypto ecosystem.
Whether you're new to crypto or expanding your digital finance toolkit, knowing how to buy, swap, and transfer USDT is fundamental. This guide breaks down each step clearly and securely, helping you navigate the process with confidence.

How to Swap USDT
Swapping USDT allows you to convert it into other cryptocurrencies or stablecoins quickly. You can do this on centralized exchanges like OKX or through decentralized finance (DeFi) platforms.
Swapping USDT on the OKX Web Platform
- Go to Trade > Convert (for instant swaps) or use Spot trading for limit orders.
- Set USDT as the source token and choose your target cryptocurrency.
- Enter the amount—you can input either side and the other updates automatically.

Swapping USDT on DeFi Platforms
Decentralized exchanges (DEXs) let you swap USDT directly from your wallet without intermediaries.
However, be aware:
