Definition
A bridge moves tokens between blockchains. To move USDC from Ethereum to Polygon, you use a bridge.
Plain-English explanation
The official Polygon Portal (portal.polygon.technology) is the safest USDC Ethereum-Polygon bridge. Third-party bridges (Across, Stargate, cBridge) are faster but have more trust assumptions. For serious amounts, use the official bridge.
