USDT is the largest and most widely used stablecoin, designed to hold a 1:1 peg to the US dollar with reserves held by its issuer. It functions across dozens of blockchains as a dollar substitute for trading, payments, and liquidity, and remains the primary dollar proxy on exchanges that don't handle fiat directly. Its scale gives it deep liquidity almost everywhere crypto trades, though it also concentrates more counterparty and reserve-transparency scrutiny than most other stablecoins.
- Macro context: USDT is part of the tokenized money market, which represents only ~0.290% of global M2 money supply today.
