Tether (USDT) holds the distinction of being the largest stablecoin by market capitalization in the cryptocurrency world. Its primary function is to provide a stable bridge for transactions between various cryptocurrencies and traditional fiat currencies. Founded by iFinex, a Hong Kong-registered company that also owns the BitFinex exchange, Tether was initially launched as RealCoin in July 2014 and later rebranded in November of the same year. This stablecoin is exclusively pegged to the U.S. dollar and is backed "100% by Tether’s reserves," as stated on its official website.
Originally built on the Bitcoin blockchain, Tether has expanded its compatibility and now operates across multiple protocols, including Bitcoin’s Omni and Liquid protocols, as well as the Ethereum, TRON, EOS, Algorand, Solana, and Bitcoin Cash (SLP) blockchains. Notably, in January 2023, Tether secured the third position in the cryptocurrency hierarchy, trailing only Bitcoin (BTC) and Ethereum (ETH) in market capitalization. With a market cap nearing $68 billion, USDT played a pivotal role in high-value exchanges throughout 2022, cementing its status as the go-to stablecoin for traders and investors.
What Is a Stablecoin?
Stablecoins like Tether offer a digital asset characterized by minimal volatility, typically maintaining a consistent valuation. These coins are anchored to stable assets such as gold, the U.S. dollar, or other fiat currencies, ensuring their value remains equivalent to their pegged pair.
- Key Feature: 1 Tether = $1, regardless of market conditions.
- Market Share: Tether dominates ~53% of the total stablecoin market, followed by USD Coin (USDC, ~31%) and Binance USD (BUSD).
Stablecoins are crucial for providing unshakable liquidity in crypto markets, protecting traders from unpredictable losses caused by price fluctuations.
How Does Tether Work?
Tether’s stability stems from its robust reserve structure. The company claims to hold dollars and other assets equivalent to or exceeding the total USDT tokens in circulation. Essentially, for every Tether issued, the company holds $1 in reserves (cash or cash-like assets such as short-term securities).
- Transparency: Tether regularly discloses reserve amounts versus circulating USDT on its website.
- Regulatory Scrutiny: Past investigations by the CFTC and New York Attorney General have focused on reserve practices.
Investors can easily acquire Tether on major crypto exchanges. For every $100 invested, ~100 USDT tokens are issued, simultaneously increasing the company’s reserves by $100 to maintain the 1:1 peg. Tokens are burned when users redeem them for fiat.
Multichain Support
Unlike having its own blockchain, Tether issues tokens via multiple third-party blockchains:
| Blockchain | Token Standard |
|---|---|
| Ethereum | USDT ERC-20 |
| TRON | USDT TRC-20 |
| Binance Smart Chain | USDT BEP-20 |
| Solana | USDT SPL |
| TON (The Open Network) | USDT TON |
This multichain compatibility enhances USDT’s utility across ecosystems—whether for low-cost Solana transactions, Ethereum DeFi integrations, or Telegram-based apps via TON.
Real-World Use Cases
Tether isn’t just a financial tool for institutions; it’s increasingly used in everyday commerce, especially in regions with volatile local currencies or limited access to USD.
- Freelancers: Workers in Argentina, Nigeria, and Turkey use USDT to receive international payments, converting to local currency at favorable rates.
- E-Commerce: Online retailers report up to 40% of international sales in USDT.
- Remittances: Cost-effective alternative to traditional wire transfers (e.g., UAE to Kenya).
- Business Treasury: Companies use USDT to stabilize revenue during market volatility.
