What you need to know

WBTC source representation

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Linea. The recorded Linea representation uses 8 decimal places. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

Leaving Linea L2 for Ethereum L1

Linea inclusion and its ethereum settlement are distinct from final receipt on Ethereum. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.

WBTC destination representation

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Ethereum receipt-side execution

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.

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.

WBTC unwrap or exchange input check

WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC 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 Ethereum bridge mistakes

Route-specific mistakes include sending on a network other than Linea; using a destination that is not valid for Ethereum; 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. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Private Route for WBTC → WBTC

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

Linea to Ethereum FAQs

What WBTC representation leaves Linea?

WBTC is a contract representation on Linea with 8 decimals at 0x3aAB2285ddcDdaD8edf438C1bAB47e1a9D05a9b4. ETH, not WBTC, 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. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

What WBTC representation arrives on Ethereum?

WBTC is a contract representation on Ethereum at 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599. ETH, not WBTC, 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Does the same WBTC ticker guarantee the same ledger form?

No. This bridge keeps the asset intent while moving between a WBTC wrapped token and a WBTC 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 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. 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 Ethereum can prevent normal detection or receipt.

Can I bridge WBTC from Linea to Ethereum without KYC?

Requirements are checked for the live WBTC Linea to 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.
