Stablecoins represent an evolution in cryptocurrency, offering exchange rate stability by pegging their value to fiat currencies, commodities, or other assets. This reduces volatility while retaining blockchain advantages like decentralization and cost-efficient transactions. Among the top dollar-pegged stablecoins, USDT, USDC, and DAI dominate the market.
