On February 6th, leading prediction market platform Polymarket announced a partnership with Circle to officially initiate the migration from the bridged version USDC.e to the native USDC on Polygon. This adjustment will be implemented in phases over the coming months, aiming to optimize settlement structures, reduce systemic risk, and enhance overall trading stability. In the past, most DeFi platforms relied on cross-chain bridges to facilitate stablecoin circulation, but bridging itself involves complex smart contracts and external verification networks, which have long been considered high-risk components. Data shows that since 2020, DeFi has suffered over $2 billion in asset losses due to bridge vulnerabilities. Polymarket's switch to native USDC means the platform will no longer depend on third-party bridging mechanisms, fundamentally reducing potential attack surfaces.
