Ethereum is classified as a native asset for this route. ETH uses a native asset on Optimism. The recorded Optimism representation uses 18 decimal places. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
This route crosses two L2 execution environments. Optimism settles to ethereum, while Arbitrum settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
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.
BNB is classified as a native asset for this route. BNB uses a network-specific contract asset on Arbitrum. The recorded Arbitrum 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.
Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Optimism. EVM 0x account address An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay.
Optimism 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.
Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for Arbitrum; running out of ETH before the source transaction is submitted. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. 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. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
Optimism wallet, token-transfer, contract, log, and gas activity remain public, and Arbitrum wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Optimism to BNB 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.
ETH is listed as the native representation on Optimism; ETH is used for network gas. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
BNB is a contract representation on Arbitrum with 18 decimals at 0x20865e63B111B2649ef829EC220536c82C58ad7B. ETH, not BNB, pays gas unless both symbols are the same. 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. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. On receipt, Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
ETH is the deposited native-asset input; BNB is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
ETH is the native gas asset for Optimism. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. ETH is recorded as native on this source.
Sending ETH on a network other than Optimism, or using an address that is not valid for Arbitrum, can prevent detection or delivery. Match both network labels and representations to the active route.
Requirements are checked for the live ETH OP Mainnet to BNB Arbitrum 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.
