What exactly leaves Avalanche as USDC?
USDC is a contract representation on Avalanche at 0xb97ef9ef8734c71904d8002f8b6bc66dd9c48a6e. AVAX, not USDC, pays gas unless both symbols are the same. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. 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. Verify the destination contract and keep ETH available for OP Mainnet activity.
Why does the USDC to OP direction matter?
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. On receipt, OP receipt is a governance-token balance, not destination gas. Verify the destination contract and keep ETH available for OP Mainnet activity.
What changes between the source and destination asset roles?
