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.

Receiving stablecoin USDT

USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The destination wallet must support the exact Polygon representation. The route converts a native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

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.

USDT output identity and receiving

Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Polygon. The recorded Polygon representation uses 6 decimal places. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

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.

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.

Mistakes specific to BNB Arbitrum to USDT 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; selecting a stablecoin by ticker without checking its network contract. 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Private Route for BNB → USDT

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 USDT 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.

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 USDT?

USDT is a contract representation on Polygon with 6 decimals at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. POL, not USDT, pays gas unless both symbols are the same.

Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Why does the BNB to USDT 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, Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

What changes between the source and destination asset roles?

BNB is the deposited native-asset input; USDT is the quoted stablecoin 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Which stablecoin contract must this route match?

USDT must match the quoted Polygon representation. A ticker or target price is not enough to identify a token contract.

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.

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