Tether (USDT) is one of the most widely used stablecoins in the cryptocurrency ecosystem. Designed to maintain a 1:1 value with the U.S. dollar, USDT provides traders, investors, and businesses with a reliable digital asset for transactions, hedging, and value preservation. As of 2025, Tether continues to dominate the stablecoin market with a massive circulating supply and integration across major blockchain networks.
Understanding Tether USD (USDT)
Tether is a fiat-collateralized stablecoin, meaning each USDT token is backed by reserves held in U.S. dollars or dollar-denominated assets. Issued by Tether Limited, the coin allows users to transact in a blockchain-based currency without exposure to the volatility typically associated with cryptocurrencies like Bitcoin or Ethereum.
Tether operates across multiple blockchains, including Ethereum (ERC-20), Tron (TRC-20), BNB Chain (BEP-20), and others, making it highly accessible and interoperable across exchanges and decentralized applications.

USDT Price and Market Data
| Metric | Value |
|---|---|

| Market Capitalization | $157.78 billion |
| 24-Hour Trading Volume | $31.38 billion |

Despite its stable value, USDT occasionally trades slightly above or below $1.00 due to market demand and liquidity conditions—common behavior for stablecoins on decentralized exchanges.
The All-Time High of $1.16 was recorded in March 2017, reflecting early market uncertainty about its backing. Since then, increased transparency efforts have helped stabilize confidence in the token.
How Tether Works: Technology and Infrastructure
Multi-Chain Issuance
Tether is issued on several blockchain platforms using different token standards:
- ERC-20 (Ethereum)
- TRC-20 (Tron)
- BEP-20 (BNB Chain)
- Omni Layer (Bitcoin)
- Polygon (PoS)
Each version functions similarly but incurs different transaction fees and confirmation speeds depending on the underlying network.
Proof of Reserves and Transparency
Tether Limited employs a proof-of-reserves model to verify that its circulating supply is fully backed by reserves. Regular attestation reports are published on its official transparency page, detailing holdings in cash, cash equivalents, and other assets.
While full real-time auditing remains a topic of debate, Tether has improved disclosure practices over time, responding to regulatory scrutiny and market demand for accountability.
Minting and Burning Mechanism
Tether uses a burn-and-mint supply model:
- Users deposit U.S. dollars into Tether’s bank accounts.
- Tether issues an equivalent amount of USDT tokens.
- When users redeem USDT, tokens are burned, and fiat is returned.
Only Tether Limited can alter the total supply, maintaining centralized control over issuance—a trade-off for stability and predictability.
