What Are Stablecoins?
Stablecoins are cryptocurrencies designed to maintain a stable value by pegging to fiat currencies like the US dollar. They combine the benefits of blockchain technology (fast transactions, decentralization) with the price stability of traditional money. USDT (Tether) and USDC (USD Coin) dominate the stablecoin market, but they differ in critical ways.
What Is USDT?
Launched in 2014, Tether (USDT) is the oldest and largest stablecoin by market cap ($110+ billion). Operated by Tether Limited, it’s pegged 1:1 to the US dollar and operates on blockchains like Ethereum, Tron, and Solana. USDT is widely used for trading, remittances, and hedging against crypto volatility. However, it has faced scrutiny over its reserve transparency.
What Is USDC?
USD Coin (USDC), launched in 2018 by Circle and Coinbase, is the second-largest stablecoin with a $30+ billion market cap. Backed by regulated financial institutions, USDC emphasizes transparency with monthly audited reserves. It’s available on Ethereum, Solana, and other blockchains, and is favored for DeFi, cross-border payments, and institutional use.
