Stablecoins bridge the gap between blockchain-powered digital assets and everyday transactions by eliminating volatility risks inherent in cryptocurrencies like Bitcoin or Ethereum. Tether's USD-backed stablecoin, USDT, leads the market with the highest capitalization, available globally on exchanges and peer-to-peer platforms. As part of the Ledger Ecosystem, USDT is easily managed as an ERC-20 token via Ethereum wallets.
Understanding USDT: A Stablecoin Powerhouse
What is USDT?
USDT is a stablecoin pegged 1:1 to the U.S. dollar, issued by Tether—a centralized entity founded in 2012. With a market cap exceeding $144 billion (as of 2025), USDT dominates 60% of the stablecoin market and ranks as the third-largest crypto asset after BTC and ETH.
