Tether
The world's largest stablecoin, pegged 1:1 to the U.S. dollar and used as the backbone of crypto trading.
Overview
Tether (USDT) is the first and most widely used stablecoin in cryptocurrency, launched in July 2014 originally under the name 'Realcoin' and rebranded to Tether shortly afterward. It was co-founded by Brock Pierce, Reeve Collins, and Craig Sellars, and issued initially on the Omni Layer atop Bitcoin. Each USDT token is designed to maintain a 1:1 peg with the U.S. dollar, meaning one USDT should always be worth approximately one dollar. Tether achieves this peg by holding reserves of cash, cash equivalents, U.S. Treasury bills, and — to a smaller degree — secured loans, gold, Bitcoin, and other assets that back the total supply of USDT in circulation.
USDT is issued natively on more than a dozen blockchains including Ethereum (the largest chain by USDT supply), Tron (the largest by USDT transaction count, particularly for retail transfers in emerging markets), Solana, Avalanche, TON, Aptos, Cosmos, Algorand, and many others. This multi-chain issuance makes USDT one of the most accessible dollar-denominated tokens in the world. It consistently ranks as one of the most traded crypto assets by daily volume, often surpassing even Bitcoin, and moves more real-world payments and remittance value than any other single crypto asset. For many traders, USDT serves as a dollar-denominated safe haven within crypto markets — a place to park value during volatile periods without converting back to fiat currency and re-paying banking fees.
Tether has faced significant scrutiny over the years regarding the transparency of its reserves and its relationship with the Bitfinex exchange (both controlled by iFinex Inc.). In 2021, the CFTC fined Tether $41M for making misleading statements about being 'fully backed'; the New York Attorney General's office reached an $18.5M settlement covering separate reserve-disclosure issues. In response, Tether has significantly increased its attestation reporting — quarterly reports are now produced by BDO Italia and detail reserve composition to the asset class level. As of recent reports, U.S. Treasury bills make up the vast majority of Tether's reserves (over 80%), with a growing cash equivalent buffer, secured overnight repo positions, and small allocations to Bitcoin and gold. Tether has become one of the largest single holders of short-term U.S. Treasuries in the world.
Tether's business is enormously profitable due to the interest earned on Treasury holdings while USDT itself pays no yield to holders. In 2024 Tether reported over $13B in profit, funding investments across AI infrastructure, energy, agriculture, and Bitcoin mining. The company has also moved its official domicile to El Salvador and continues to operate primarily outside the U.S. regulatory perimeter, which is both a strength (fewer restrictions on issuance) and a risk (potential enforcement action if regulations tighten).
USDT is the de facto unit of account in cryptocurrency markets. Most trading pairs on major exchanges are denominated in USDT, and it serves as the primary bridge between fiat currencies and crypto assets — particularly on offshore exchanges where direct fiat access is limited. Its availability across a dozen-plus blockchains makes it the most liquid and accessible dollar-denominated token in the world. For hundreds of millions of people in developing countries — Argentina, Turkey, Nigeria, Venezuela, and increasingly Southeast Asia — USDT provides access to dollar-denominated savings without needing a U.S. bank account, functioning as informal 'digital dollars' in economies with currency controls or high inflation. This real-world utility, more than its trading role, is why USDT continues to grow even as regulated competitors like USDC gain share in Western institutional markets.
How It Works
The basics
Tether operates as a centralised, fiat-backed stablecoin. The company Tether Limited mints new USDT tokens when customers (typically institutional counterparties with Tether Mint accounts) deposit dollars, and burns (destroys) tokens when customers redeem them.
Going deeper
Retail users generally interact with USDT on the secondary market — exchanges, DEXs, wallets — rather than minting or redeeming directly. The peg is maintained through arbitrage: if USDT drops below $1 on secondary markets, arbitrageurs buy it cheaply, redeem for $1 from Tether, and pocket the difference; if USDT trades above $1, they deposit dollars to mint new USDT and sell at the premium.
Under the hood
This market mechanism keeps the price anchored near $1 within a tight band, though during acute crypto-market stress USDT can briefly depeg — most notably during the May 2022 Terra collapse, when it fell to around $0.95 for several hours before recovering. Tether can also freeze specific addresses at the smart-contract level in response to law enforcement requests, and has done so for hundreds of millions of dollars in stolen or sanctioned funds over the years — a centralisation trade-off users implicitly accept when holding USDT.
Pros & Cons
- Most liquid stablecoin with the highest trading volume and broadest exchange support
- Available on dozens of blockchains, providing maximum flexibility
- Serves as the primary trading pair for most cryptocurrency markets worldwide
- Provides dollar-denominated savings access to people in countries with unstable currencies
- Reserves are now predominantly U.S. Treasury bills, the safest fixed-income asset
- Centralized — Tether Limited can freeze or blacklist addresses holding USDT
- Historical lack of transparency about reserves, though this has improved significantly
- Has never undergone a full independent audit (relies on attestations instead)
- Regulatory risk — governments may impose restrictions on offshore stablecoin issuers
- Concentrated counterparty risk — value depends entirely on Tether Limited's solvency
Use Cases
- Trading pair for buying and selling cryptocurrencies on exchanges
- Storing value in dollar terms during crypto market downturns
- Cross-border remittances — sending dollars globally in minutes for pennies
- Dollar-denominated savings for individuals in countries with high inflation
- Settlement currency for over-the-counter (OTC) institutional crypto trades
