What you need to know

ARB input identity and handling

Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.

From BNB Chain L1 into Linea L2

BNB Chain source execution occurs on L1, while Linea delivery occurs on a separate L2 ledger that settles to ethereum. BNB pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.

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

Linea destination 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.

WETH output identity and receiving

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.

BNB Chain source execution

BNB Chain is a L1 EVM network in the BNB Chain ecosystem. BNB pays source-side network gas on BNB Chain. EVM 0x account address A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20.

EVM-to-EVM execution boundary

BNB Chain and Linea 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 ARB BNB Chain to WETH Linea

Route-specific mistakes include sending on a network other than BNB Chain; using a destination that is not valid for Linea; running out of BNB before the source transaction is submitted; treating a wrapped token as the native gas asset. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. 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 ARB → WETH

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

Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.

What exactly arrives on Linea as WETH?

WETH is a contract representation on Linea with 18 decimals at 0xe5D7C2a44FfDDf6b295A15c148167daaAf5Cf34f. ETH, not WETH, pays gas unless both symbols are the same.

Why does the ARB to WETH direction matter?

Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. On receipt, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

What changes between the source and destination asset roles?

ARB is the deposited token input; WETH is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending ARB?

Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. 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.

Can the wrapped asset pay native network gas?

No. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. 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.

What funds the BNB Chain source transaction?

BNB is the native gas asset for BNB Chain. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. ARB is token-tracked and can need approval before transfer.

Can I swap ARB on BSC to WETH on Linea without KYC?

Requirements are checked for the live ARB BSC to WETH 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.
