2月6日消息，领先的预测市场平台Polymarket宣布与Circle合作，正式启动从桥接版本USDC.e迁移至Polygon原生USDC的计划。此次调整将在未来数月内分阶段完成，目标是优化结算结构、减少系统性风险，并提升整体交易稳定性。
过去，多数DeFi平台依赖跨链桥接来实现稳定币流通，但桥接本身涉及复杂的智能合约和外部验证网络，长期被视为高风险环节。数据显示，自2020年以来，DeFi因桥接漏洞造成的资产损失已超过20亿美元。Polymarket此次切换至原生USDC，意味着平台将不再依赖第三方桥接机制，从根本上降低潜在攻击面。
与桥接资产不同，Polygon原生USDC直接存在于链上，无需中转或锁仓映射。该结构不仅减少了操作层级，也缩短了资金结算路径，使交易更高效、更可控。对预测市场而言，稳定币的安全性和流动效率是核心基础，这一迁移将显著提升Polymarket的清算可靠性。
社区对该决定普遍持正面态度。部分用户认为，原生USDC的引入将改善资金周转速度，同时降低因合约漏洞或跨链故障带来的不确定性。行业分析人士指出，越来越多DeFi项目正在转向原生资产，以取代桥接代币，这已成为基础设施升级的重要方向。
通过与Circle的合作，Polymarket不仅强化了自身结算体系，也为依赖跨链资产的DeFi平台提供了可复制的安全路径。随着原生稳定币逐步取代桥接资产，预测市场及整个DeFi生态的风险结构有望持续优化。
