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 Arbitrum. The recorded Arbitrum 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.

Leaving Arbitrum L2 for Polygon L1

Arbitrum inclusion and its ethereum settlement are distinct from final receipt on Polygon. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.

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.

SOL output identity and receiving

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Polygon. The recorded Polygon representation uses 9 decimal places. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Arbitrum source execution

Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Arbitrum. EVM 0x account address On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval.

EVM-to-EVM execution boundary

Arbitrum 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. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.

Mistakes specific to BNB Arbitrum to SOL Polygon

Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Polygon; running out of ETH before the source transaction is submitted. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Private Route for BNB → SOL

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

What exactly leaves Arbitrum as BNB?

BNB is a contract representation on Arbitrum with 18 decimals at 0x20865e63B111B2649ef829EC220536c82C58ad7B. ETH, not BNB, pays gas unless both symbols are the same. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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 Polygon as SOL?

SOL is a contract representation on Polygon with 9 decimals at 0xd93f7E271cB87c23AaA73edC008A79646d1F9912. POL, not SOL, 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 SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Why does the BNB to SOL 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, Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

What changes between the source and destination asset roles?

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

Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

What funds the Arbitrum source transaction?

ETH is the native gas asset for Arbitrum. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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 Arbitrum, 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 BNB on Arbitrum to SOL on Polygon without KYC?

Requirements are checked for the live BNB Arbitrum to SOL 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.
