There appears to be some confusion regarding "USDT1." Currently, there is no cryptocurrency officially known as "USDT1." However, it's possible that this term is a misinterpretation or typographical error related to two distinct stablecoins: Tether (USDT) and USD1.

🪙 Tether (USDT)

Tether (USDT) is one of the most widely used stablecoins in the cryptocurrency market. Launched in 2014 by Tether Limited Inc., USDT is pegged to the U.S. dollar at a 1:1 ratio, aiming to provide stability in the volatile crypto market. It operates on multiple blockchains, including Ethereum, Tron, and others. As of May 2025, Tether has a market capitalization exceeding $152 billion and is the most traded cryptocurrency globally, surpassing even Bitcoin in daily trading volume .

💵 USD1 by World Liberty Financial (WLFI)

USD1 is a newer stablecoin introduced in April 2025 by World Liberty Financial, a fintech company based in Miami, Florida. Like Tether, USD1 is designed to maintain a 1:1 peg with the U.S. dollar.
