Stablecoins are a type of cryptocurrency designed to maintain price stability by pegging their value to more stable assets. These reference assets can include fiat currencies like the US Dollar ($USD) or Euro (€EUR), or commodities such as gold (XAU).
Understanding Stablecoins: A Quick Overview
According to Deutsche Bank Research (March 2022):
_"Stablecoins are cryptocurrency tokens pegged to fiat currencies. Primarily used for trading and lending crypto assets, they serve as key enablers of decentralized finance (DeFi)—permissionless blockchain-based financial services. Stablecoins are categorized into three types based on collateralization:
1) Off-chain collateralized (e.g., Tether),
2) On-chain collateralized (e.g., Dai), and
3) Uncollateralized algorithmic stablecoins."_
Key points to note:
- Stablecoins are not legal tender but aim for price stability.
- They act as safe havens during crypto market volatility by preserving purchasing power through DeFi protocols.
