1. The core difference between USDC and USDT

It regularly publishes third-party audit reports to ensure that each USDC is supported by US dollars or short-term Treasury bonds, and is more compliant.

   • USDT: The Omni Layer protocol, which was originally based on Bitcoin, was later expanded to multiple chains such as Ethereum (ERC-20), Tron (TRC-20), and has a wide coverage but an old technical architecture.

   • USDC: It is mainly based on the Ethereum ERC-20 standard, and supports high-performance chains such as Solana and Algorand. It has stronger cross-chain interoperability and is suitable for complex application scenarios such as DeFi.

4. Market application and acceptance

   • USDT: The market value of circulating has been ranked first in the long run (about 144.1 billion as of March 2025), and is widely used in exchange trading pairs, over-the-counter markets and gray economy fields.

   • USDC: Due to its compliance advantages, it is more favored by institutions and DeFi platforms. For example, mainstream exchanges such as Coinbase and OKX preferentially support USDC trading pairs.
