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 Linea as AVAX?
AVAX is a contract representation on Linea with 18 decimals at 0x5471ea8f739dd37E9B81Be9c5c77754D8AA953E4. ETH, not AVAX, pays gas unless both symbols are the same. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token 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. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token 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 Linea, can prevent detection or delivery. Match both network labels and representations to the active route.
