What exactly leaves Arbitrum as ARB?
ARB is a contract representation on Arbitrum at 0x912ce59144191c1204e64559fe8253a0e49e6548. ETH, not ARB, 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. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.
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 ARB to AVAX direction matter?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. On receipt, Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
What changes between the source and destination asset roles?
ARB is the deposited token input; AVAX is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending ARB?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not 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. 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.
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. ARB is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending ARB on a network other than Arbitrum, or using an address that is not valid for Avalanche, can prevent detection or delivery. Match both network labels and representations to the active route.
