What you need to know

BNB input identity and handling

BNB is classified as a native asset for this route. BNB uses a network-specific contract asset on Linea. The recorded Linea representation uses 18 decimal places. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling.

Linea to Arbitrum L2 handoff

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

WBTC wrapped-token output 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 destination token on Arbitrum. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Arbitrum destination execution

Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Arbitrum. EVM 0x account address An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately.

WBTC output identity and receiving

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Arbitrum. The recorded Arbitrum representation uses 8 decimal places. 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.

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 Arbitrum 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 BNB Linea to WBTC Arbitrum

Route-specific mistakes include sending on a network other than Linea; using a destination that is not valid for Arbitrum; 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. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. 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 BNB → WBTC

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