ETH to ARB is a same-chain swap

Why people swap ETH for ARB
Swapping ETH for ARB moves you from a layer-1 asset into a scaling network's token. People do this to take exposure to a rollup's growth, or because they are becoming active on Arbitrum and want its native token for governance and ecosystem use.
What Ethereum and Arbitrum actually are
Ethereum (ETH): Ethereum is the leading smart contract platform powering DeFi, NFTs, and thousands of decentralized applications. ETH is used to pay for transactions across the Ethereum ecosystem. Buy Ethereum instantly with ChainATM. Just type "Buy ETH" and the AI handles the rest.
Arbitrum (ARB): Arbitrum is the leading Ethereum Layer 2 scaling solution using optimistic rollup technology. ARB is the governance token of the Arbitrum ecosystem. Buy Arbitrum with ChainATM by typing "Buy ARB", no bridge or DEX required.
What to watch on this pair
- Because both tokens live on Ethereum, this settles as a single on-chain swap. You pay one set of Ethereum gas fees and there is no bridging delay or bridge risk.
- The rate you see quoted is an estimate until the transaction settles. ChainATM shows the expected output and total cost before anything executes, and nothing moves until you approve it.

How do I convert ETH to ARB?
Converting, exchanging, changing, switching and trading ETH for ARB all describe the same operation: a swap. Open ChainATM and say "Convert my ETH to ARB". The AI finds the route, shows the rate and estimated output, and waits for your approval before anything executes.
Can you swap ETH for ARB directly?
Yes. You do not need to sell ETH for cash first and buy ARB afterwards. ChainATM routes the swap in one step, including across chains, and the ARB lands in your own wallet.
Where can I swap ETH to ARB?
In ChainATM, at app.chain-atm.com or in the iOS app. Because it is self-custody, your ETH never sits in an exchange account waiting to be withdrawn: the swap happens from your own wallet and the ARB arrives in it.
Can I transfer ETH to ARB?
Not as a transfer, and the distinction matters. A transfer moves the same asset between addresses. ETH and ARB are different assets, so what you need is a swap, which exchanges one for the other. Sending ETH to an address that expects ARB can lose the funds permanently.
