Full Explanation
A stablecoin is a type of cryptocurrency engineered to maintain a stable value, typically by pegging it to a fiat currency such as the US dollar at a 1:1 ratio. While Bitcoin's price can swing 10% in a day, one USDC is designed to always be worth about one dollar.
The two largest stablecoins are USDC (issued by Circle) and USDT (issued by Tether). Both are backed by reserves of cash and short-term assets, though the transparency and quality of those reserves has historically varied between issuers — USDC is generally regarded as the more transparently audited of the two.
Stablecoins serve several important roles. Traders use them to move in and out of volatile positions without converting back to fiat through a bank, which is slow and may trigger fees. On decentralized exchanges like Hyperliquid, USDC is the primary collateral currency. And in countries with unstable local currencies, stablecoins function as an accessible dollar-equivalent savings tool.
The main risk is the peg itself: if an issuer's reserves are insufficient or a panic occurs, a stablecoin can temporarily 'depeg' below its target value, as has happened to several stablecoins during market stress events.
