Fiat collateralized stablecoin: the "digital dollar" in the encryption world

In the rapid development of the Crypto Assets market, stablecoins play a bridging role, connecting TradFi with Decentralization ecosystems. Among the various types of stablecoins, fiat-collateralized stablecoins have become the most widely used category in the market due to their relative stability and broad acceptance.

Fiat-collateralized stablecoins refer to: each stablecoin is backed by an equivalent amount of fiat currency (such as USD, EUR) as reserve assets. This mechanism ensures that its value always maintains a 1:1 exchange ratio with the fiat currency it is pegged to, allowing users to redeem it back to real-world fiat currency at any time.

How Do Fiat Reserves Work?

The issuing institution of fiat-collateralized stablecoins typically holds an equivalent reserve of fiat in banks or financial custodians. For example, if a user purchases USDT with 100 dollars, Tether must have 100 dollars in cash or equivalent assets in its reserve account to back it. These reserves are held by third-party custodians and are audited regularly to enhance market trust.

However, although these stablecoins claim to have "full reserves", the transparency and audit frequency vary by project, and investors should remain vigilant to check for credible audit reports and whether they genuinely disclose their holdings structure.

Mainstream Fiat-Collateralized Stablecoins Overview

1. Tether (USDT) As one of the earliest and most representative fiat stablecoins, USDT has long dominated the crypto market. As of the end of June 2024, the market capitalization of USDT has surpassed 112 billion USD, making it the third largest crypto asset globally. It is widely used in exchange pairs, cross-border settlements, and DeFi liquidity pools.
2. TrueUSD (TUSD) TUSD is another stablecoin pegged to the US dollar, favored by some institutions for its auditing transparency and compliance positioning. Its reserve status can be viewed on the real-time audit page, providing an additional option in terms of compliance and stability.
3. Other stablecoins Stablecoins such as USDC and FDUSD also belong to the category of fiat-backed stablecoins. They play an important role as a medium of exchange in various exchanges around the world, providing users with convenient trading access and ways to store value.

##Advantages and Disadvantages of Fiat-Collateralized Stablecoins Advantages:

• The coin value is stable, pegged to fiat currencies such as the US dollar, with extremely low volatility.
• Easy to accept, widely used in trading, DeFi, and payment fields
• Provide fiat "on-chain" channels to reduce cross-border transfer costs Potential risks:
• High degree of centralization, controlled by the issuing institution, with credit risk.
• The transparency of reserves relies on the auditors, and insufficient information disclosure may trigger a trust crisis.
• Easily affected by regulatory policies, facing compliance review pressure

##Summary Fiat-backed stablecoins, due to their stability and high liquidity, have become an indispensable part of the crypto economic system. They serve as the "digital dollar" in various scenarios such as trading matching, payment clearing, and DeFi applications. In the future, as regulatory systems gradually improve and auditing mechanisms become increasingly transparent, fiat stablecoins will continue to occupy a mainstream position for a long time, providing foundational liquidity support to the crypto market.
