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 DAI

DAI is a crypto-backed dollar-oriented stablecoin whose canonical and bridged contracts vary by network. Its peg design does not make two network representations interchangeable. The destination wallet must support the exact Optimism representation. The route converts a native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

DAI output identity and receiving

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Optimism. The recorded Optimism representation uses 18 decimal places. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Optimism destination execution

Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Optimism. EVM 0x account address An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance.

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.

Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Optimism; 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. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance.

Private Route for BNB → DAI

Arbitrum wallet, token-transfer, contract, log, and gas activity remain public, and Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this BNB on Arbitrum to DAI on Optimism 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.
