Choose the WETH asset and BNB Chain network you currently hold.
Check the estimated output, fees, timing, and Optimism destination network.
Open the live route and follow the exact deposit instructions.
Use the receipt and status page until the destination funds arrive.
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on BNB Chain. The recorded BNB Chain 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.
BNB Chain source execution occurs on L1, while Optimism 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 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 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.
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.
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 BNB Chain. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Route-specific mistakes include sending on a network other than BNB Chain; using a destination that is not valid for Optimism; 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. 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.
BNB Chain 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 BNB Chain 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.
WETH is a contract representation on BNB Chain with 18 decimals at 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. BNB, not WETH, pays gas unless both symbols are the same. 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. 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.
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.
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.
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. 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.
EVM 0x account address Do not substitute a BNB Chain address merely because a wallet displays both networks.
Sending on a network other than BNB Chain, selecting a representation not listed by the quote, or entering an address invalid for Optimism can prevent normal detection or receipt.
Requirements are checked for the live WETH BNB Chain 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.
