1. Reserve Management

• Reserve AssetsTether Limited claims that each USDT token is backed by equivalent reserve assets, including cash, cash equivalents, short-term deposits, and other financial instruments such as U.S. Treasury bonds. These reserves serve as a safety net to ensure the stability of USDT's value.

• Issuance and redemption: When users purchase USDT, the equivalent amount of US dollars will be added to the reserve of Tether. Conversely, when USDT is exchanged for fiat currency, the corresponding amount will be deducted from the reserve. This process ensures that the total supply of USDT always matches the reserve, maintaining its value at 1 US dollar.

2. Market Mechanism

• ArbitrageIf the price of USDT on the exchange is lower than $1, traders will buy USDT, hoping to exchange it for a fiat currency worth $1 or use it to buy other cryptocurrencies at a discount. This buying pressure will push the price of USDT back towards $1. Similarly, if the price of USDT rises above $1, traders can sell USDT for profit, bringing the price back to $1.

• Market ConfidenceTether largely relies on the market's belief that Tether has sufficient reserves. As long as traders believe that USDT can be exchanged for real US dollars, they are willing to accept it at a close to 1:1 exchange rate.

3. Transparency and Audit

• Periodic ReportTether Limited regularly releases detailed reports on the composition of its reserves. These reports are designed to reassure users and ensure the backing of USDT as claimed.

• reserve proofTether emphasizes that the reserve supporting its stablecoin is always equal to or greater than the total USDT in circulation. However, the company has been criticized for failing to transparently prove its reserves.

4. Blockchain Infrastructure

• Multi-chain supportTether operates on multiple blockchains, including Ethereum, Tron, and Algorand. This multi-chain support makes Tether versatile and easily accessible in different blockchain ecosystems.

• Security measuresTether employs advanced security features, including multi-signature protocols and real-time monitoring tools, to prevent fraud and double spending.

Controversy and challenge

• Reserve TransparencyCritics argue that Tether has not consistently provided clear evidence of its reserves, raising questions about whether all USDT tokens are fully backed.

• Regulatory reviewTether is facing regulatory scrutiny and legal challenges over its claim to be fully backed by US dollars. These challenges have sparked ongoing debates about its transparency and operational integrity.

Conclusion

Tether strives to maintain a 1:1 ratio with the US dollar through reserve management, market mechanisms, and transparency. Despite controversies related to reserve transparency and regulatory scrutiny, Tether has successfully maintained its remarkable stability. This stability has earned the trust of traders, investors, and global enterprises, making it one of the most widely used stablecoins in the cryptocurrency ecosystem.
