What Is Tether (USDT)? How Does Tether Work?

·

Abstract
Tether (USDT) is one of the most popular stablecoins, maintaining a 1:1 value ratio with the US dollar. It operates across multiple blockchains and has seen growing trading volumes and liquidity in recent years. Like other stablecoins, USDT benefits cryptocurrency trading by shielding users from market volatility and eliminating conversion delays between crypto and fiat currencies.

Introduction

Tether is a cornerstone of the crypto ecosystem. As of December 2020, it ranked as the fourth-largest cryptocurrency by market cap (~$200B), trailing only Bitcoin, Ethereum, and XRP. Its daily trading volume often surpasses Bitcoin’s. But what exactly is Tether, and how can you use it effectively?

Launched in 2014 as "Realcoin," USDT was the first stablecoin pegged to fiat currency. Initially issued via Bitcoin’s Omni Layer, it later expanded to blockchains like Ethereum (as ERC-20), TRON, Solana, and others. Despite early price fluctuations, USDT has stabilized significantly since 2019, attributed to rising adoption and broader crypto market maturity.

How Does Tether (USDT) Work?

Stablecoins derive utility from their price stability. USDT was originally 100% backed by USD reserves, with each token representing $1. Over time, its collateral expanded to include cash equivalents, loans, and other assets.

As Tether’s whitepaper states:

All Tether tokens are pegged 1:1 with their corresponding fiat currencies and are backed 100% by Tether’s reserves. Reserve holdings are published daily and updated at least once per 24 hours.

While USDT/USD typically trades at parity, major market events can cause temporary deviations.

Why Is Tether (USDT) Important?

USDT bridges crypto and fiat systems, enabling investors to trade dollars at a 1:1 ratio while avoiding crypto volatility. Its stability makes it a preferred medium for trading other tokens.
