How to
Three steps, and only the second one involves your wallet.
Type what you want to send, then paste the address that should receive the ETH. We check it against Base before anything is created.
We generate an address for this exchange only. Send from your own wallet, whenever you are ready — nothing moves before you do, and there is no account to fund first.
Once ERC20 confirms your deposit, the exchange and the payout take seconds. The ETH goes straight to your address — no balance, no withdrawal step.
What you actually get
The payout network fee is a fixed amount, so the smaller the swap, the more of it that fee eats — which is why this table exists instead of one headline rate.
| You send | You get | Effective rate | Cost of size |
|---|---|---|---|
| 50 ARB | 0.0032581 ETH | 0.00006516 | −7.18% |
| 200 ARB | 0.0138137 ETH | 0.00006907 | −1.62% |
| 500 ARB | 0.0349223 ETH | 0.00006984 | −0.51% |
| 2,000 ARB | 0.14041 ETH | 0.00007021 | best rate on this pair |
Quoted by the desk at , refreshed every few minutes. The percentage compares each line's effective rate with the best one in this table — it is the price of swapping small, not a fee we charge.
The two sides
ARB is the governance token of Arbitrum, the largest Ethereum layer-2 network. It is used to vote in the Arbitrum DAO — gas on Arbitrum itself is paid in ETH, not in ARB. More about Arbitrum.
On this pair it moves over ERC20 — an address there starts with 0x — 42 characters.
ARB also exists on other networks — different addresses, not interchangeable: Arbitrum.
Ether is the native asset of Ethereum, the smart-contract network that hosts most tokens and DeFi applications. It pays the gas fee of every transaction on that network, including transfers of ERC20 tokens. More about Ethereum.
On this pair it moves over Base — an address there starts with 0x — 42 characters.
ETH also exists on other networks — different addresses, not interchangeable: Arbitrum, BEP20, ERC20, Linea, Manta, Optimism.

FAQ
Using it
13.0754 ARB right now. The desk sets it live and it moves with the Base network fee — below it, that fee would eat the swap. There is no fixed maximum on this pair.
A Base address you control — it starts with 0x — 42 characters. ETH exists on several networks; an address from another one looks valid and the coins would be unrecoverable, so we check it against Base before creating anything.
Around 10-60 minutes end to end, as forecast by the desk right now. Most of that is ERC20 confirming your deposit — the exchange and the payout themselves take seconds.
Money & privacy
Yes — pick Fixed in the module. The rate is locked when the exchange is created, and a countdown starts for your deposit.
Two things come out: the Base network fee for sending your payout — 0.0000028 ETH right now — shown on its own line, and our margin, which is already inside the rate. Nothing is added after you confirm.
No. There is no account to create and we never ask for identity documents, at any amount. The one case where a swap can be held is spelled out in the AML policy rather than hidden.
On-chain, yes: ERC20 and Base are public ledgers, so the deposit and the payout are visible to anyone, like any other transaction on them. What nobody can link them to is an identity: there is no account, no document and no request log here — the privacy policy names the only parties in the path.
Every order takes an optional refund address, and it is worth filling in. If the exchange cannot go through — a deposit under the minimum, a pair that stops being quoted, or the one documented case of a flagged deposit where the law allows a return — the deposit goes back to that address, minus what the network charges to send it; we charge nothing for a refund. Without a refund address, a return has to be arranged by hand through support. The order page tells you which situation you are in; nothing is decided silently.
