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.
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.
Ethereum is a L1 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Ethereum. EVM 0x account address An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.
POL (ex-MATIC) is classified as a governance or utility token for this route. POL uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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.
Polygon and Ethereum can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories.
Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for Ethereum; running out of POL before the source transaction is submitted; 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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
Polygon wallet, token-transfer, contract, log, and gas activity remain public, and Ethereum wallet, token-transfer, contract, log, and gas activity remain public. For this WETH on Polygon to POL on Ethereum 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.
POL is a contract representation on Ethereum at 0x455e53cbb86018ac2b8092fdcd39d8444affc3f6. ETH, not POL, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
WETH is the deposited token input; POL is the quoted token 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.

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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.
POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WETH is token-tracked and can need approval before transfer.
Requirements are checked for the live WETH Polygon to POL Ethereum 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.
