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 Linea. The recorded Linea 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.

Linea to Optimism L2 handoff

This route crosses two L2 execution environments. Linea settles to ethereum, while Optimism settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.

WETH destination representation

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Optimism. The recorded Optimism 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.

Optimism receipt-side execution

Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Optimism. EVM 0x account address 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.

Linea deposit-side execution

Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Linea. EVM 0x account address A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones.

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 Linea. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Linea to Optimism bridge mistakes

Route-specific mistakes include sending on a network other than Linea; using a destination that is not valid for Optimism; running out of ETH before the source transaction is submitted; treating a wrapped token as the native gas asset. A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. 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 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. 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

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

Linea to Optimism FAQs

What WETH representation leaves 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 source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. 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 Optimism?

WETH is a contract representation on Optimism with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, 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. 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 Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. 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. 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 Linea address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

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

Can I bridge WETH from Linea to Optimism without KYC?

Requirements are checked for the live WETH Linea to Optimism 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.
