USDT (USD Tether) has become one of the most widely used stablecoins in the cryptocurrency ecosystem. As a U.S. dollar-pegged digital asset, USDT offers traders and investors a reliable way to maintain value without the volatility commonly associated with cryptocurrencies like Bitcoin or Ethereum. Issued by Tether Limited, each USDT token is backed by reserves that include cash and cash equivalents, ensuring its 1:1 value with the U.S. dollar.
Available across multiple blockchains—including Ethereum, Tron, Solana, Algorand, and Binance Smart Chain (BSC)—USDT's multi-chain compatibility enhances its utility for fast, low-cost transactions. This flexibility makes it ideal not only for trading but also for transferring value globally, serving as a digital equivalent of cash within decentralized finance (DeFi) and centralized platforms alike.
For traders, USDT acts as a safe haven during market turbulence and a primary pairing for countless crypto assets on exchanges. Understanding how to buy, swap, and transfer USDT is essential for anyone entering the world of digital finance.

Transit time varies by network but typically takes a few minutes.
Transferring USDT via OKX Wallet Browser Extension
- Open the extension and select USDT.
