Standard Bridged USDC.e (Optimism) is a token that enables users to transfer USDC from Ethereum to Optimism, a layer-2 network focused on enhancing scalability and lowering gas costs. Through the Optimism bridge, USDC tokens are deposited and locked, while an equivalent amount of USDC.e is issued on Optimism. These USDC.e tokens can then be utilized across applications built on Optimism.
