2月28日消息，Cardano宣布部署USDCx稳定币框架，与Circle合作接入xReserve体系，实现1:1铸造与赎回机制。该举措显著提升Cardano链上美元计价流动性，即便当前总锁定价值（TVL）仍处于低位区间。
USDCx并非原生USDC，而是通过桥接机制与Circle储备挂钩的代币。用户可通过以太坊跨链铸造或销毁USDCx完成赎回，并将流动性导入去中心化交易应用。首批已完成实时集成的平台包括Minswap、Liqwid与SundaeSwap，为“Cardano稳定币流动性增长”“USDCx跨链铸造机制”提供落地场景。
链上数据显示，截至目前，Cardano稳定币市值约3400万美元，而TVL约为1.37亿美元。稳定币规模上行与DeFi活跃度低迷形成对比，DEX交易量与网络手续费仍处低位，说明资金更多以保守的美元资产形式停留，尚未大规模进入借贷或杠杆策略。
业内分析认为，此次优先建设“合规稳定币基础设施”，有助于为支付、资金管理及机构级DeFi应用铺路。历史上，稳定币深度不足曾限制Cardano承载美元计价贷款与现实世界资产实验的能力。如今在“Cardano DeFi生态复苏路径”“USDCx如何提升链上结算效率”等议题下，网络选择先完善底层流动性，而非追逐短期收益。未来TVL能否回升，将取决于稳定币资金是否转化为实际链上需求。
