The core differences between USDC (#纳斯达克加密ETF扩容 USDC) and other mainstream stablecoins (such as USDT, DAI, etc.) are mainly reflected in the following aspects:

1. Issuer and Backing Method

- USDC: Issued by compliant institutions such as Circle and Coinbase, claiming to be fully backed 1:1 by USD reserves, short-term government bonds, and other assets, regularly subjected to independent audits, with high transparency.

​

- USDT (Tether): Issued by Tether, early transparency regarding backing assets was questionable (some reserve composition has been gradually 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 US dollar, with no direct backing from real-world assets.
