What exactly leaves Ethereum as BNB?
BNB is a contract representation on Ethereum at 0xb8c77482e45f1f44de1745f52c74426c631bdd52. ETH, not BNB, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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 WBTC?
WBTC is a contract representation on Arbitrum with 8 decimals at 0x2f2a2543B76A4166549F7aaB2e75Bef0aefC5B0f. ETH, not WBTC, 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.
