Tether (USDT)

USDT’s main role is liquidity. Many crypto exchanges list trading pairs against Tether, allowing users to move in and out of digital assets without returning to the traditional banking system for every transaction. It is also used for cross-border transfers, payments, DeFi activity, and as a temporary store of value during periods of market volatility. Because it exists on public blockchains, USDT can be transferred between compatible wallets and platforms, although network fees and exchange charges may apply.

Tether says its tokens are backed by reserves that include cash, cash equivalents, US Treasury bills, and other assets. The composition and transparency of those reserves have been frequent areas of scrutiny, and USDT has attracted regulatory and market debate because of its scale and importance to crypto trading. Despite that controversy, Tether remains a core piece of market infrastructure, functioning as a digital dollar substitute for users who need fast blockchain-based settlement and broad exchange acceptance.
