Tether USDt, or USDT, is a digital token that was launched in 2014. It is designed to facilitate the use of traditional fiat currencies in a digital way, intending to provide an alternative to the conventional financial system with a digital approach to money. Tether (USDT) is pegged to the value of a U.S. dollar (also known as a stablecoin). Tether's issuer claims that USDT is backed by bank reserves and loans that match or exceed the value of USDT in circulation. This digital dollar is powered by blockchain technology and exists on several blockchains, including Algorand, Avalanche, Ethereum, EOS, and more. Important note: at this time, Coinbase only supports USDT on the Ethereum blockchain (ERC-20). Do not send USDT to Coinbase on any other blockchain.
