What is the different between usd and usdt: USD is the US dollar, the official currency of the United States 💵. USDT, on the other hand, is Tether, a type of cryptocurrency that's supposed to be pegged to the value of the US dollar 😎.

So, 1 USDT is meant to be equal to 1 USD, but it's not exactly the same thing – USDT is a digital token on blockchains like Ethereum, while USD is physical cash and coins issued by the government.
