Introduction

Tether USD (USDT) is the world's largest stablecoin by market capitalization and one of the most traded digital assets globally. It is designed to maintain a stable value of 1 US Dollar per token, giving crypto users a reliable way to move value without exposure to the price volatility typical of most cryptocurrencies.

History & Background

Tether was originally launched in 2014 under the name 'Realcoin' before being rebranded to Tether. It was built on the Omni Layer, a protocol on top of the Bitcoin blockchain. Over the years, Tether Limited expanded USDT to many more blockchains, dramatically increasing its accessibility and transaction speed options for users worldwide.

How Tether USD Works

Every USDT token is intended to be backed 1:1 by reserves held by Tether Limited. When a user deposits US dollars with Tether, new USDT tokens are minted. When tokens are redeemed, they are burned and the corresponding dollars are returned. This mint-and-burn mechanism is what keeps the peg close to $1.

Tether publishes periodic reserve attestations to demonstrate that the outstanding supply of USDT is covered by real-world assets, primarily US Treasury bills, cash, and cash equivalents.

Tokenomics

USDT has no fixed maximum supply. Its total supply expands and contracts based on market demand. When demand for a stable dollar-denominated asset rises, more USDT is minted; when demand falls, tokens are redeemed and burned. This elastic supply model allows USDT to scale with the broader crypto market.
