Swap Ethereum to Arbitrum
Describe a ETH to ARB swap in plain language, check the route, networks and costs in the proposal, and confirm it in the ChainATM iOS app.
How to swap ETH to ARB
Open ChainATM
Open the ChainATM app on your iPhone.
Describe the swap
"Swap my ETH to ARB" or "Convert 0.5 ETH to ARB".
Check the proposal
Check the route, networks, provider, expected output and costs. If no route is shown, the swap is not available.
Confirm or cancel
Nothing is executed until you confirm. You can also cancel.
What happens in a ETH to ARB swap
A swap exchanges ETH for ARB. Whether ChainATM can prepare this swap depends on the exact assets, networks, amount and the routes available at that moment. If a route is available, the app shows a proposal with the provider, route, expected output and costs. A route across networks may use a provider such as LI.FI. Nothing is executed until you confirm the proposal.
Why people swap ETH for ARB
Swapping ETH for ARB moves value from a layer-1 blockchain asset into a layer-2 network token. The swap changes which asset and which risks you hold.
What to check on this pair
- Check the source and destination networks in the proposal. ETH and ARB can exist on more than one network, and the versions are not interchangeable.
- If the route crosses networks, it uses a bridge. That usually takes longer than a swap on one network, can involve fees on both sides, and adds the risk of the bridge contract.
- A quote is an estimate until the transaction settles. Check the expected output, provider, network fees and any other costs shown before you confirm.
FAQ: Swapping ETH to ARB
How do I swap ETH to ARB?
Open the ChainATM iOS app and type or say "Swap my ETH to ARB". If the swap can be prepared, the app shows a proposal with the amount, route, networks and estimated output. A typed or spoken request is not approval. In the current reviewed flows, you see a proposal and confirm it in the app before execution is requested.
Can I swap ETH to ARB across different networks?
Sometimes. A route across networks may be available through a provider such as LI.FI, depending on the exact assets, networks and amount. This page is not a promise that a route exists. If the app shows no route, the swap is not available at that moment.
What does a ETH to ARB swap cost?
The swap itself uses no ChainATM credits. Each message you send to the AI in chat uses 1 credit, and the credit packs are listed on the pricing page. ChainATM adds no fee or markup of its own. Network, provider and bridge costs still apply. Some are built into the quoted amount rather than listed separately, so check what you pay and what you receive before you confirm.
How do I convert ETH to ARB?
Converting, exchanging, switching and trading ETH for ARB all mean the same operation: a swap. You can phrase the request any of these ways in the app. Check the proposal before you confirm.
Can I transfer ETH to ARB?
Not as a transfer. A transfer moves the same asset between addresses. ETH and ARB are different assets, so you need a swap. Sending ETH to an address that expects ARB can lose the funds permanently.
Does ChainATM hold my funds?
ChainATM does not operate an omnibus customer wallet or hold crypto on its own balance sheet. The default embedded wallet is provided by Privy. After you confirm a supported action, execution may use ChainATM's authenticated backend and Privy's wallet infrastructure, or request approval from a connected external wallet, depending on the route. A confirmation screen is not proof that every action is signed only on your device or universally gated by a passkey.
