Tether (USDT) is one of the most widely recognized stablecoins in the digital asset space, engineered to maintain a 1:1 value peg with the U.S. dollar. Unlike volatile cryptocurrencies such as Bitcoin or Ethereum, USDT offers stability, making it a cornerstone in the global crypto ecosystem. Available across multiple blockchains, Tether has seen explosive growth in trading volume and liquidity over recent years, becoming a preferred tool for traders, investors, and institutions navigating the fast-moving crypto markets.
As a bridge between traditional finance and decentralized digital assets, USDT enables seamless transactions without exposing users to the sharp price swings typical of cryptocurrencies. It eliminates the need for repeated conversions between fiat and crypto—saving time, reducing fees, and increasing transactional efficiency.
By the end of 2020, Tether ranked as the fourth-largest cryptocurrency by market capitalization, nearing $20 billion—trailing only Bitcoin, Ethereum, and XRP. Notably, USDT frequently surpasses even Bitcoin in daily trading volume, underscoring its critical role in global crypto liquidity.
What Is Tether (USDT)?
Launched in 2014 under the original name Realcoin, Tether was co-founded by Bitcoin investor Brock Pierce, entrepreneur Reeve Collins, and software developer Craig Sellers. Initially issued on the Bitcoin blockchain via the Omni Layer protocol, USDT has since expanded to operate across numerous blockchain networks.
Today, the majority of USDT supply exists as an ERC-20 token on the Ethereum blockchain. However, Tether is also available on other prominent chains including TRON (TRC20), EOS, Algorand, Solana, and OMG Network—enhancing its accessibility and interoperability.
While Tether has achieved remarkable adoption, it has also faced scrutiny and controversy—common challenges for leading crypto projects. In its early years, USDT experienced price volatility, briefly trading above $1.20 during periods of market stress. However, since 2019, its price stability has significantly improved due to increased market maturity, higher trading volumes, and greater transparency efforts.

How Does Tether (USDT) Work?
The primary appeal of Tether lies in its stability—a stark contrast to traditional cryptocurrencies known for wild price fluctuations. As a fiat-collateralized stablecoin, each USDT token is designed to be backed by reserves equivalent to one U.S. dollar.
According to Tether’s original whitepaper:
“Each Tether token issued into circulation is backed 1:1 by corresponding fiat currency held in reserves by Tether Limited, based in Hong Kong.”
Originally backed solely by U.S. dollar deposits, Tether’s reserve composition has evolved. Today, its backing includes cash, cash equivalents, short-term deposits, and secured loans—collectively aimed at maintaining the 1:1 parity with the USD. While this shift has sparked debate about transparency and audit practices, regular attestation reports from independent firms aim to reinforce confidence in its reserve integrity.
Tether operates through a mint-and-burn mechanism:
- When users deposit USD with Tether Limited, new USDT tokens are minted and credited to their accounts.
- When users redeem USDT for USD, those tokens are burned (removed from circulation), ensuring supply aligns with demand.
This model allows for dynamic scalability while preserving the fundamental promise of price stability.
Why Is Tether (USDT) Important?
Despite ongoing debates about its reserves and governance, Tether plays a vital role in connecting decentralized finance with traditional financial systems. It provides investors with a digital asset that mirrors the stability of fiat currency while enabling instant transfers across borders and platforms.
For traders, USDT serves as a safe haven during market downturns. Instead of converting crypto holdings into fiat—a process that can take days and incur high fees—users can quickly swap into USDT within minutes.
Key features of Tether include:
- 1:1 USD parity – Designed to maintain consistent value.
- High liquidity – One of the most traded digital assets globally.
- Multi-chain availability – Operates across major blockchains for flexibility.
- Wide utility – Used in trading, remittances, hedging, and more.
These attributes make USDT indispensable in both centralized exchanges and decentralized applications (dApps).
Common Use Cases for Tether (USDT)
Rapid Market Stability Access
During sharp market corrections—such as a sudden drop in Bitcoin’s price—traders can instantly convert their holdings into USDT. This protects capital without exiting the crypto ecosystem.
Fast Cross-Exchange Fund Transfers
Tether enables quick movement of funds between exchanges. This is especially valuable for arbitrage strategies where timing is critical. Unlike bank transfers, USDT transactions settle in minutes regardless of geographic location.

Trading on Crypto-Only Exchanges
Many exchanges do not support direct fiat deposits or withdrawals. With USDT already in hand, users can trade freely on these platforms without relying on traditional banking infrastructure.
Forex-Style Trading Strategies
Because USDT mirrors the USD, users can engage in currency speculation. For example, someone holding a local currency weaker than the dollar might convert funds into USDT when their currency is strong—then later reconvert when it weakens—effectively profiting from exchange rate shifts.
How to Store Tether (USDT)
Storing USDT securely requires careful attention due to its presence across multiple blockchains. While keeping USDT on exchanges like Binance offers convenience, it's generally safer to use dedicated crypto wallets.
Available storage options include:
- Web and mobile wallets like Trust Wallet
- Hardware wallets such as Ledger (supports ERC-20 and TRC20 versions)
- Custodial services provided by regulated platforms
⚠️ Critical Note: Always ensure you send and receive USDT using the same network type. For example:
- Sending ERC-20 USDT to a TRC-20 address may result in permanent fund loss.
- Binance supports multiple networks: BEP2, BEP20, ERC20, OMNI, TRC20—choose wisely during withdrawal.
As of late 2020, Ledger only supports ERC-20 and TRC-20 versions of USDT; OMNI-based tokens cannot be stored on Ledger devices.
Other Tether Stablecoins
Beyond USDT, Tether Ltd. issues several other stablecoins pegged to different assets:
- EURT: Pegged 1:1 to the Euro
- CNHT: Linked to the Chinese Yuan (CNY)
- XAUT: A gold-backed stablecoin—each token represents one troy ounce of physical gold stored in Swiss vaults
These alternatives cater to diverse financial needs, offering stability in different currencies or tangible assets.
