WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Polygon. The recorded Polygon representation uses 18 decimal places. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
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.
Polygon source execution occurs on L1, while zkSync Era delivery occurs on a separate L2 ledger that settles to ethereum. POL pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.
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.
Polygon is a L1 EVM network in the Polygon ecosystem. POL pays source-side network gas on Polygon. EVM 0x account address A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1.
WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the source token on Polygon. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for zkSync Era; running out of POL before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. 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.
Polygon 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 WETH on Polygon 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.
WETH is a contract representation on Polygon with 18 decimals at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. POL, not WETH, pays gas unless both symbols are the same. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
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.
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. On receipt, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
WETH 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.
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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.
No. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.
Requirements are checked for the live WETH Polygon 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.
