常见问题Frequently Asked Questions

Dai (DAI) 是什么？What is Dai (DAI)?+

Dai 与 USDC、USDT 有什么区别？What is the difference between Dai, USDC, and USDT?+
主要区别在于抵押方式：USDC 和 USDT 是由法币资产 1:1 抵押的中心化稳定币，而 Dai 是通过加密资产超额抵押的去中心化稳定币。Dai 无需信任中心化机构，依靠算法和智能合约维持锚定，更符合加密精神。The main difference is the collateral method: USDC and USDT are centrally-issued stablecoins 1:1 collateralized by fiat assets, while Dai is a decentralized stablecoin over-collateralized by crypto assets.
