Tether (USDT): A Comprehensive Guide


Recommended Posts

Introduction to Tether

Tether (USDT) is a type of cryptocurrency known as a stablecoin. It was first launched in 2014 and is issued by Tether Ltd. The main objective of Tether is to bridge the gap between fiat currencies and cryptocurrencies while maintaining a stable value, almost equivalent to the U.S. dollar, hence the ticker USDT.

What is a Stablecoin?

Stablecoins are a category of cryptocurrencies designed to minimize price volatility. This is done by pegging their market value to an external reference or reserve, such as a commodity or a fiat currency like the US dollar, euro, or yen. Tether, in particular, claims to back each USDT token with a single U.S. dollar held in reserve.

How Does Tether Work?

The idea behind Tether is relatively simple. It operates on the premise that each USDT token issued into circulation is backed by an equivalent amount of U.S. dollars held in reserve by Tether Ltd. When users purchase USDT, the equivalent amount of USD is supposedly taken out of circulation, and the USDT tokens are issued. Similarly, when USDT is redeemed, the tokens are destroyed, and the equivalent USD is returned to the user.

Tether operates on multiple blockchain networks, including Bitcoin (via the Omni Layer protocol), Ethereum (as an ERC20 token), TRON, EOS, and others. This compatibility allows Tether to leverage the benefits of these platforms, such as speed, security, and smart contract functionality.

Use Cases of Tether

Tether serves several purposes in the cryptocurrency ecosystem:

Price Stability: Due to its 1:1 peg with the U.S. dollar, Tether provides a buffer against the price volatility of cryptocurrencies, making it a safe haven during market downturns.

Trading Pair: USDT is commonly used as a trading pair on crypto exchanges. It allows traders to quickly move funds between different cryptocurrencies without converting to fiat.

Value Transfer: With its stable value, USDT can be used for transferring value between platforms or across borders quickly and efficiently.

DeFi Applications: USDT is commonly used within the DeFi ecosystem due to its stability and widespread acceptance.

Criticisms and Controversies

Despite its popularity, Tether has faced several criticisms and controversies. The company's claim that each USDT is backed by a dollar in reserve has been a point of contention. There have been concerns about whether Tether Ltd. indeed has enough reserves to back all USDT in circulation.

In early 2021, the New York Attorney General's office announced a settlement with Tether Ltd. over a probe into the company's operations. While Tether Ltd. admitted to no wrongdoing, the company was required to provide regular reports on its reserves.


Tether plays a critical role in the cryptocurrency ecosystem by providing a stable asset in a market known for its volatility. Its wide adoption and extensive use in trading and transfers underline its importance. However, you should be aware of the criticisms and controversies surrounding the coin and exercise due diligence when using USDT or any other cryptocurrency.
