USDT, initially known as Realcoin, was launched in 2014 by a collaboration between Brock Pierce, Reeve Collins, and Craig Sellars. USDT is an Ethereum-based stablecoin commonly regarded as a digital currency pegged to the US dollar.

USDT allows users to trade with the stability of fiat currencies in the volatile cryptocurrency market. Users can purchase, sell, or trade cryptocurrencies using USDT without worrying about the typical price fluctuations of digital assets.

Moreover, USDT is a multi-chain asset that can be used on major blockchains such as Ethereum, Solana, Tron, Algorand, Avalanche, Bitcoin Cash's Simple Ledger Protocol (SLP), EOS, Liquid Network, Omni, and more.

The price stability mechanism of USDT makes it a popular choice for stablecoin in the cryptocurrency trading market, offering traders a more convenient way to engage in digital asset trading without concerns about value fluctuations caused by price changes. Currently, all major cryptocurrencies are traded with USDT, giving it high liquidity.
