USDT
USDT is a U.S. dollar-pegged stablecoin issued by Tether and widely used to move value between crypto markets.
USDT, often called Tether, is a stablecoin designed to track the value of one U.S. dollar. It is issued by Tether Limited and exists on several blockchains, including Ethereum, Tron, and others. Unlike Bitcoin or Ether, USDT is not meant to fluctuate widely in price; its purpose is to provide a digital token that behaves like cash in dollar terms. The peg is supported by reserves held by the issuer, though users should understand that it depends on the issuer’s ability to maintain redemption and market confidence.
USDT matters because it is one of the most common ways traders and crypto users move dollar-like value without leaving blockchain-based markets. Exchanges often list trading pairs such as BTC/USDT or ETH/USDT, letting users price assets in dollars and switch between volatile crypto assets and a more stable unit. For example, someone might sell Bitcoin for USDT during a market downturn, then later use that USDT to buy another asset or transfer funds to a different exchange, while avoiding the delay of a traditional bank transfer.
