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.

Polygon destination execution

Polygon is a L1 EVM network in the Polygon ecosystem. POL pays destination-side network gas on Polygon. EVM 0x account address A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.

BNB output identity and receiving

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 BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

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 Polygon can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories.

Mistakes specific to ARB BNB Chain to BNB Polygon

Route-specific mistakes include sending on a network other than BNB Chain; using a destination that is not valid for Polygon; running out of BNB before the source transaction is submitted. 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 Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Private Route for ARB → BNB

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

What exactly leaves BNB Chain as ARB?

ARB is a contract representation on BNB Chain with 18 decimals at 0x0acdb582C1d5512Ea31fD64b9C07882CB31E494D. BNB, not ARB, 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. 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 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 receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Why does the ARB to BNB 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, Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

What changes between the source and destination asset roles?

ARB is the deposited token input; BNB is the quoted native-asset 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 Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

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.

What is the most dangerous wrong-network mistake here?

Sending ARB on a network other than BNB Chain, or using an address that is not valid for Polygon, can prevent detection or delivery. Match both network labels and representations to the active route.

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

Requirements are checked for the live ARB BSC to BNB Polygon 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.
