What exactly leaves Arbitrum as ETH?
ETH is listed as the native representation on Arbitrum; ETH is used for network gas. 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 ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
What exactly arrives on Avalanche as AVAX?
AVAX is listed as the native representation on Avalanche; AVAX is used for network gas. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
Why does the ETH to AVAX direction matter?
