Optimism is classified as a governance or utility token for this route. OP uses a network-specific contract asset on Optimism. The Optimism side is contract-tracked rather than a native gas balance. OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network.
USDC is an issued dollar-oriented stablecoin with canonical, native, and bridged variants across networks. Contract events and issuer controls differ from a network-native gas asset. The destination wallet must support the exact zkSync Era representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.
This route crosses two L2 execution environments. Optimism settles to ethereum, while zkSync Era settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on zkSync Era. The zkSync Era side is contract-tracked rather than a native gas balance. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on zkSync Era. EVM 0x account address A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.
Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Optimism. EVM 0x account address An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay.
Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for zkSync Era; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Optimism wallet, token-transfer, contract, log, and gas activity remain public, and zkSync Era wallet, token-transfer, contract, log, and gas activity remain public. For this OP on Optimism to USDC on zkSync Era path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
OP is a contract representation on Optimism at 0x4200000000000000000000000000000000000042. ETH, not OP, pays gas unless both symbols are the same. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network.
USDC is a contract representation on zkSync Era at 0x1d17cbcf0d6d143135ae902365d2e5e2a16538d4. ETH, not USDC, pays gas unless both symbols are the same. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. On receipt, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
OP is the deposited token input; USDC is the quoted stablecoin output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
USDC must match the quoted zkSync Era representation. A ticker or target price is not enough to identify a token contract.
ETH is the native gas asset for Optimism. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. OP is token-tracked and can need approval before transfer.
Requirements are checked for the live OP OP Mainnet to USDC zkSync quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
