What exactly leaves Scroll as USDC?
USDC is a contract representation on Scroll with 6 decimals at 0x06eFdBFf2a14a7c8E15944D1F4A48F9F95F663A4. ETH, not USDC, pays gas unless both symbols are the same. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.
What exactly arrives on Optimism as OP?
OP is a contract representation on Optimism at 0x4200000000000000000000000000000000000042. ETH, not OP, pays gas unless both symbols are the same. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. OP receipt is a governance-token balance, not destination gas.
