Tether (USDT) is the world’s largest stablecoin, a type of cryptocurrency designed to maintain a stable 1:1 price peg with the US dollar. Unlike volatile assets like Bitcoin, 1 USDT is engineered to always equal exactly $1 USD, backed by cash, short-term U.S. Treasury bills, and other liquid reserves held by its parent company, Tether Limited.

As the primary liquidity engine of the global crypto market, USDT is the most actively traded digital asset, with its market value scaling over $183 billion and daily trading volume frequently outpacing Bitcoin itself.
