The core differences between USDC and other mainstream stablecoins (such as USDT, DAI, etc.) are mainly reflected in the following aspects:

1. Issuing entities and endorsement methods

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

​

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

​

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