What Is USDT (Tether) and How Does It Work?
A Cryptocurrency Designed Not to Move
Most cryptocurrencies are known for volatility — prices that can swing sharply within hours. USDT, also called Tether, was built to solve exactly that problem. It’s a stablecoin, meaning it’s designed to consistently hold a value of $1 USD, combining the technology of crypto with the price stability of a traditional currency.
How USDT Stays Pegged to the Dollar
Tether Limited, the company behind USDT, states that every USDT token in circulation is backed by reserves — assets like cash, cash equivalents, and short-term securities — roughly equal in value to the number of tokens issued. In theory, this backing is what allows USDT to be redeemed for real dollars and keeps its market price anchored near $1. We look at Tether’s business model and how it profits from these reserves in more depth in How Does Tether Make Money?
Why USDT Runs on Multiple Blockchains
Unlike bitcoin, which has its own dedicated blockchain, USDT is issued on top of several different blockchains, including Ethereum, Tron, and others. This means a USDT transaction’s speed and fee depend on which network it’s sent over. When buying or selling USDT, it’s important to confirm which network is being used, since sending funds on the wrong network can result in a failed or unrecoverable transfer.
The same amount of USDT can arrive over several different blockchains, and each one has its own speed and its own cost. Before you send or receive, agree the network as explicitly as you agree the amount. A transfer sent over a network the receiving wallet does not support may not arrive at all, and there is no support desk on a blockchain to reverse it.
Why USDT Is So Widely Used in Iraq
USDT has become one of the most searched and traded cryptocurrencies among Iraqi crypto users, and for a clear reason: it offers dollar-denominated stability without requiring a foreign bank account. For people looking to hold value outside of the Iraqi dinar, or to send and receive dollar-equivalent funds quickly, USDT fills a practical gap that traditional banking often doesn’t. See How Iraqis Are Using Stablecoins to Protect Their Savings for a closer look at this trend.
USDT vs Holding Actual US Dollars
USDT is designed to track the dollar’s value, but it isn’t literally a US dollar — it’s a digital token whose value depends on Tether’s ability to honor its backing. This is an important distinction to understand: USDT offers dollar-like stability and blockchain-based portability, but it carries its own set of risks distinct from holding physical currency or a bank deposit.
| USDT | Cash dollars | A bank balance in dollars | |
|---|---|---|---|
| What you actually hold | A token recorded on a blockchain | The note in your hand | A claim on the bank |
| What keeps it worth a dollar | The issuer’s reserves and its ability to redeem | Nothing needs to — it is the dollar | The bank staying solvent and open to you |
| How it moves across a border | Over a network, in minutes | In a bag, with everything that implies | Through correspondent banks, if they accept you |
| Main risk | The issuer, and sending on the wrong network | Theft, loss and counterfeit notes | Access rules that can change without you |
How to Buy and Use USDT
USDT can be bought directly through Kurdcoin, verified and settled in Iraqi dinar. Once purchased, it can be held, sent to another wallet, or converted back to IQD when needed. Our complete USDT buying guide covers the process from account setup to your first purchase.
USDT vs USDC
USDT isn’t the only dollar-pegged stablecoin — USDC is another widely used alternative, issued by a different company with a different reserve structure. We compare the two in detail in USDT vs USDC: A Technical Comparison.
