#美国国债 USDC's core differences from other mainstream stablecoins (such as USDT, DAI, etc.) are primarily reflected in the following aspects:

1. Issuance entity and endorsement method

- USDC: Issued by compliant institutions such as Circle and Coinbase, claims to be fully backed 1:1 by USD reserves and short-term government bonds, regularly undergoes independent audits, and has high transparency.

​

- USDT (Tether): Issued by Tether, the transparency of the backing assets was questionable in the early stages (some reserve composition has been gradually disclosed in recent years), and it has faced accusations of "over-issuance."

​

- DAI: A decentralized stablecoin generated based on collateral on the Ethereum chain (such as collateralized ETH and other crypto assets), pegged to the USD, with no direct backing from real-world assets.
