What you need to know

WETH input identity and handling

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.

Leaving Linea L2 for BNB Chain L1

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

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.

BNB Chain destination execution

BNB Chain is a L1 EVM network in the BNB Chain ecosystem. BNB pays destination-side network gas on BNB Chain. EVM 0x account address A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas.

BNB output identity and receiving

BNB is classified as a native asset for this route. BNB uses a native asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Linea source 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.

EVM-to-EVM execution boundary

Linea and BNB Chain can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.

Mistakes specific to WETH Linea to BNB BNB Chain

Route-specific mistakes include sending on a network other than Linea; using a destination that is not valid for BNB Chain; 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. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Private Route for WETH → BNB

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