How the Sasquatch deposit route works

1. Select the source

Choose the WETH asset and Polygon network you currently hold.

2. Review the route

Check the estimated output, fees, timing, and Linea destination network.

3. Create the order

Open the live route and follow the exact deposit instructions.

4. Track delivery

Use the receipt and status page until the destination funds arrive.

What you need to know

WETH source representation

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.

From Polygon L1 into Linea L2

Polygon source execution occurs on L1, while Linea 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.

WETH destination representation

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Linea. The recorded Linea representation uses 18 decimal places. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Linea receipt-side execution

Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Linea. EVM 0x account address A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.

Polygon deposit-side execution

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 unwrap or exchange input check

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.

Polygon to Linea bridge mistakes

Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for Linea; 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. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Private Route for WETH → WETH

Polygon wallet, token-transfer, contract, log, and gas activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this WETH on Polygon to WETH on Linea 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.

Polygon to Linea FAQs

What WETH representation leaves Polygon?

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.

What WETH representation arrives on Linea?

WETH is a contract representation on Linea with 18 decimals at 0xe5D7C2a44FfDDf6b295A15c148167daaAf5Cf34f. ETH, not WETH, pays gas unless both symbols are the same. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Does the same WETH ticker guarantee the same ledger form?

No. This bridge keeps the asset intent while moving between a WETH wrapped token and a WETH wrapped token. Match the source and output details in the live quote.

Which gas balances matter for this bridge?

A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. The bridge output does not automatically fund every later gas need.

What destination address should be used?

EVM 0x account address Do not substitute a Polygon address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Polygon, selecting a representation not listed by the quote, or entering an address invalid for Linea can prevent normal detection or receipt.

Can I bridge WETH from Polygon to Linea without KYC?

Requirements are checked for the live WETH Polygon to Linea 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.
