Swap AVAX from Avalanche C-Chain to ETH on Arbitrum One

Swap AVAX from Avalanche C-Chain to ETH on Arbitrum One. Native AVAX leaves C-Chain, and native ETH is what can arrive on Arbitrum One. Both are gas coins, on different networks.

The quote prints 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on both sides because that sentinel means native gas, not one shared asset. Outbound it is AVAX on Avalanche C-Chain, chain id 43114, checked on Snowtrace. Inbound it is ETH on Arbitrum One, chain id 42161, checked on Arbiscan. It is not WETH, not Ethereum mainnet ETH, and not Arbitrum Nova.

Diagram for Swap AVAX from Avalanche C-Chain to ETH on Arbitrum One
AVAX leaves Avalanche C-Chain. ETH is what can arrive on Arbitrum One.

Same sentinel, two fee coins that cannot substitute

A wallet that still shows chain id 43114 after the transfer will keep displaying AVAX and will not reveal the ETH. Switch to 42161 and read the native ETH line. Do not import the sentinel as a token. There is no approval step for either gas coin. There is a fee in AVAX on the way out, so the amount of AVAX you sell cannot be the entire balance.

This ETH is not the ether on chain id 1

Ethereum mainnet blocks are about 12 seconds and the explorer is Etherscan. Arbitrum One is an L2 with its own ETH balance for gas. Bridging AVAX here does not refill a mainnet wallet. It also does not put ETH on Base or on Nova. If a friend asked for mainnet gas, this route answers a different request. Arbitrum One is the arrival network, and only that network.

Contracts that want WETH will reject this arrival

WETH on Arbitrum is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Native ETH and that ERC-20 are not interchangeable until someone wraps. WBTC is a separate wrapped claim and is not native bitcoin; it is not what this quote delivers either. If the app's spend function names WETH, change routes before you sell the AVAX. Arriving in the fee coin and then wrapping is a second transaction you may not have planned.

X-Chain AVAX and Nova are both off this map

C-Chain only for the source. Arbitrum One only for the destination. An X-Chain address cannot sign the EVM transaction Snowtrace would record. A Nova wallet will not show the ETH this quote can deliver. Read the minimum ETH against the AVAX you are spending. Price moves while a bridge is open, and this page does not offer a delivery clock.

Frequently asked questions

What is the best way to swap AVAX from Avalanche C-Chain to ETH on Arbitrum One?

The quote prints 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on both sides because that sentinel means native gas, not one shared asset. Outbound it is AVAX on Avalanche C-Chain, chain id 43114, checked on Snowtrace.

Why does AVAX to ETH show one address twice?

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE marks native gas. On Avalanche C-Chain, chain id 43114, it is AVAX. On Arbitrum One, chain id 42161, it is ETH. Snowtrace and Arbiscan are different explorers. The balances are not the same coin, and neither one is an ERC-20 you approve. The quote minimum is the floor, and a thin floor is a reason to stop.

Can I use this ETH on Ethereum mainnet?

No. The arrival is Arbitrum One. Ethereum is chain id 1, about 12 second blocks, explorer Etherscan. Nova is not included either. AVAX left C-Chain and became L2 ETH for gas on 42161. If you needed mainnet fees, this route is the wrong destination. A block interval is not a delivery time for the bridge.

What if the app only accepts WETH?

Use the WETH route. Native ETH from this page is the gas sentinel, not 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Wrapping later is a separate step that itself needs ETH for gas. If the contract rejects native ETH, signing this quote does not finish the job. Switch the wallet to the destination chain before you judge the balance.
