What exactly leaves Arbitrum as SOL?
SOL is a contract representation on Arbitrum with 9 decimals at 0x2bcC6D6CdBbDC0a4071e48bb3B969b06B3330c07. ETH, not SOL, 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 SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.
What exactly arrives on Ethereum as WBTC?
WBTC is a contract representation on Ethereum at 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599. ETH, not WBTC, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Why does the SOL to WBTC direction matter?
