Polygon Bridged USDC (Polygon PoS) news today is centered on the continuing transition from USDC.e to native USDC on Polygon PoS, although no new USDC.e-specific announcement dated September 22–24, 2026 was identified. The most relevant development remains Polygon’s migration initiative, which encourages decentralized-finance protocols, bridges, marketplaces, and other ecosystem participants to replace the Ethereum-bridged token with native USDC.
