1. What Is Tether (USDT)?
Tether (USDT) is a blockchain-powered cryptocurrency issued by Tether Limited. Each USDT in circulation is backed by a 1:1 reserve of USD held in designated bank accounts, making its value pegged to the U.S. dollar. Unlike volatile cryptocurrencies like Bitcoin or Ethereum, USDT maintains minimal price fluctuations—stabilizing around $1—which classifies it as a stablecoin.
As of August 2023, USDT remains the highest-valued stablecoin by market capitalization ($100 billion), ranking fourth among all cryptocurrencies. It also leads in 24-hour trading volume, solidifying its position as a dominant trading asset. Tether Limited also issues other fiat-pegged cryptocurrencies, such as EURT (Euro), CNHT (Chinese Yuan), and XAUT (gold-backed).

3. Why Does USDT Exist on Multiple Blockchains?
Blockchain interoperability limitations led Tether to deploy USDT across different networks:
- Omni Layer (Bitcoin)
- Ethereum
- Tron
- EOS
- Algorand
- Others (Liquid, SLP)
Key Differences:
- Ethereum USDT: Addresses start with
0x(e.g.,0xe48cd5Dbdb5Dd4E49850967793D92F5B78026b99). - Omni Layer USDT: Addresses begin with
1–3(e.g.,3H9WTNDzCrEyGJQhAfs6bbVXYpHRNK4XK4).
⚠️ Warning: Sending USDT to an incompatible blockchain (e.g., Omni to Ethereum) may result in permanent loss. Always verify addresses before transacting.
65% of USDT circulates on Ethereum, offering higher liquidity for traders.
4. How Does USDT Maintain Its Dollar Peg?
Three primary methods stabilize crypto prices:
- Fiat-Collateralized (e.g., USDT): Backed by USD reserves.
- Crypto-Collateralized (e.g., DAI): Overcollateralized with other cryptocurrencies.
- Algorithmic: Adjusts supply dynamically (no collateral).
USDT’s Transparency Concerns:
Tether’s reserves have faced scrutiny due to limited audits, causing occasional depegging events (e.g., a 15% drop in 2018). Despite this, USDT retains trust as the pioneer stablecoin.
5. Why Is USDT Valuable?
Key advantages driving USDT’s adoption:
- Safe Haven: Shields traders from Bitcoin’s volatility during market crashes.
- Cost-Efficiency: Lower fees than international wire transfers.
- 24/7 Trading: Enables continuous transactions without banking hours.
- Extensive Pairings: Most exchanges offer abundant USDT trading pairs.
