## Fiat Pegged Stablecoins

Fiat pegged stablecoins are digital assets designed to maintain a constant value relative to a specific fiat currency, such as the US dollar. They achieve this through various backing mechanisms, including collateralization with fiat reserves, over-collateralization with other digital assets, or algorithmic supply adjustments.

These tokens provide a bridge between the traditional financial system and the crypto ecosystem, allowing traders to hedge volatility without exiting the blockchain. They are essential for the operation of decentralized exchanges and lending protocols, as they provide a stable unit of account.

However, they introduce significant counterparty and systemic risk, as the stability of the peg depends on the transparency and sufficiency of the reserves. If the backing is questioned, a bank run or de-pegging event can trigger contagion across the entire crypto market.

Their role as a liquidity source makes them a central pillar of modern decentralized finance.
