Tether USDT

Tether (USDT) is a stablecoin designed to track the value of the US dollar, aiming to trade at roughly one dollar per token. Launched in 2014, it is the largest and most widely used stablecoin in crypto, serving as a dollar substitute for trading, payments, and moving value between exchanges and blockchains.

How Tether works

Tether is issued by the company Tether Limited, which mints new tokens when users deposit funds and redeems tokens for fiat through authorized channels. Each USDT is intended to be backed by reserves the company says are equal to or greater than the tokens in circulation, so the supply expands and contracts with demand rather than being fixed.

Unlike Bitcoin or Ethereum, Tether is not a blockchain of its own. It is a token issued across many networks, including Ethereum, Tron, Solana, and others. The same dollar peg is maintained regardless of which chain a given USDT lives on, which lets users pick whichever network has the fees and speed they prefer.

What keeps the peg

The peg relies on the promise of redemption: if USDT trades below a dollar, arbitragers can buy it cheaply and redeem it for full value, and the reverse applies above a dollar. Confidence in the reserves backing the token is therefore central to keeping its price near one dollar.

What Tether is used for

• Trading pairs: USDT is a base currency on most exchanges, letting traders move in and out of positions without touching banks.
• Cross-border transfers: it offers a fast, dollar-denominated way to send value globally.
• Holding dollars on-chain: users park funds in USDT to avoid crypto volatility while staying in the ecosystem.
• DeFi: USDT is used as collateral, for lending, and for liquidity provision across many protocols.

Supply and reserves

Tether's supply is not capped; tokens are created and destroyed in response to deposits and redemptions. The company publishes regular attestations describing the assets backing USDT, which it reports as a mix of cash, cash equivalents such as US Treasury bills, and other holdings. Because USDT is centrally issued, the issuer has the technical ability to freeze tokens at specific addresses, typically in response to legal requests.

Risks and considerations

Tether carries counterparty and reserve risk: holders rely on the issuer to maintain adequate, liquid backing and to honor redemptions. Questions about the composition and transparency of reserves have followed Tether for years, and a serious loss of confidence could pressure the peg, as has happened briefly during market stress.

Regulatory scrutiny of stablecoins is increasing worldwide, which could affect how USDT is issued, redeemed, or used in certain jurisdictions. Because the issuer can freeze tokens, USDT is more centralized than many cryptocurrencies. Users should weigh these trade-offs against the convenience of an on-chain dollar.
