USD Coin on Optimism (USDC)

USD Coin (USDC) is a fully-reserved US-dollar stablecoin, with one USDC designed to track one US dollar. It is issued across several EVM chains, including Ethereum, Base, and Polygon, and is a staple of payments and DeFi. On Optimism, USDC moves as a ERC-20 token: transfers pay Optimism network fees in ETH and settle with the network's own finality. Every U.CASH rail that runs on Optimism, from checkout to swap, supports USDC natively on this chain.
