Stablecoins are cryptocurrencies pegged to another currency or asset class, typically fiat currencies like USD or EUR, or commodities such as gold. This peg ensures the stablecoin’s value tracks its underlying asset, theoretically reducing volatility compared to other cryptocurrencies. However, stablecoins can lose their pegs, so price stability isn’t guaranteed.
Stablecoins bridge traditional fiat currencies and cryptocurrencies, serving diverse purposes in modern crypto trading. Understanding them is essential for anyone interested in the crypto space.
In this article, we’ll explore stablecoins, highlight the leading options today, and explain why they’re gaining popularity.
What Are Fiat-Backed Stablecoins?
Fiat-backed stablecoins are virtual representations of real-world currencies minted on a blockchain. They’re created by locking fiat currencies and minting equivalent tokens via smart contracts. The locked fiat backs the stablecoin, determining its value (the "peg"). For USD-backed stablecoins like USDC and USDT, the peg is 1:1—each token represents $1 held in reserve.
Unlike traditional currencies, stablecoins enable borderless, permissionless global money transfers, contributing to their rising popularity.
