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 Polygon. The recorded Polygon 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.

From Polygon L1 into Arbitrum L2

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

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.

ARB output identity and receiving

Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on Arbitrum. The Arbitrum side is contract-tracked rather than a native gas balance. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

Polygon source execution

Polygon is a L1 EVM network in the Polygon ecosystem. POL pays source-side network gas on Polygon. EVM 0x account address A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1.

EVM-to-EVM execution boundary

Polygon 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 Polygon to ARB Arbitrum

Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for Arbitrum; running out of POL before the source transaction is submitted. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

Private Route for BNB → ARB

Polygon 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 Polygon to ARB 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.

Swap BNB on Polygon to ARB on Arbitrum FAQs

What exactly leaves Polygon as BNB?

BNB is a contract representation on Polygon with 18 decimals at 0x5c4b7CCBF908E64F32e12c6650ec0C96d717f03F. POL, not BNB, pays gas unless both symbols are the same. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling.

What exactly arrives on Arbitrum as ARB?

ARB is a contract representation on Arbitrum at 0x912ce59144191c1204e64559fe8253a0e49e6548. ETH, not ARB, 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. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

Why does the BNB to ARB direction matter?

Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. On receipt, A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

What changes between the source and destination asset roles?

BNB is the deposited native-asset input; ARB 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 BNB?

Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

What funds the Polygon source transaction?

POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. BNB is token-tracked and can need approval before transfer.

What is the most dangerous wrong-network mistake here?

Sending BNB on a network other than Polygon, 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.

Can I swap BNB on Polygon to ARB on Arbitrum without KYC?

Requirements are checked for the live BNB Polygon to ARB 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.
