USDT (United States Dollar Tether) is the world’s leading stablecoin, bridging cryptocurrencies with traditional finance. Pegged 1:1 to the US dollar, it offers price stability amid crypto market volatility, making it indispensable for trading, decentralized finance (DeFi), and arbitrage.
How Tether (USDT) and Stablecoins Work
Stablecoins like USDT are designed to minimize volatility by pegging their value to reserve assets (e.g., fiat currencies, commodities). Unlike Bitcoin or Ethereum, USDT maintains a near-constant value of $1, enabling:
- Risk mitigation during market downturns.
- Seamless transactions without price fluctuations.
- Liquidity provision for DeFi protocols.
Tether’s Peg to the US Dollar
Tether Limited claims each USDT is backed by 1 USD in reserve, ensuring stability. USDT operates across multiple blockchains, including:
- Ethereum
- Bitcoin (via Omni Layer)
- Tron
- Solana
