Exchange in 3 steps
-
Choose how much ETH to send and enter your Arbitrum address on Arbitrum One.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer ETH to the address on your order — after confirmations, ARB is sent to your wallet automatically.
What do you need to know?
- Base confirmations are usually fast — often within a minute.
- Send ETH on Base mainnet only — not Ethereum L1, Optimism, or Arbitrum unless your order says otherwise.
- Use a Base-compatible wallet and address (0x…). Leave enough ETH on Base for gas on top of the swap amount.
- ARB not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
ETH on Base — Coinbase L2
Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.
ETH on Base mainnet
Use a Base wallet for deposits. Ethereum mainnet ETH is a different network — wrong-chain sends may not be credited.
Leave enough ETH on Base for gas in addition to the amount you swap.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB not received?
Confirm your wallet is on Arbitrum One and fully synced.
ARB payout tips
- Payouts go to Arbitrum One — use a 0x-style address on the correct chain.
- Check Arbiscan with the payout tx hash if your balance has not updated.
- Do not expect ARB on Ethereum mainnet unless your order explicitly lists it.

Frequently asked questions
Do I need KYC to swap ETH to ARB?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Ethereum (Base) to Arbitrum swaps.
How long does ETH to ARB take?
Most swaps finish in 1–5 minutes. Timing depends on Base mainnet and Arbitrum One confirmations and current network load.
Is ETH to ARB non-custodial?
Yes. You send ETH from your wallet and receive ARB directly to the address you provide — SendSwap never holds your keys.
What if I send ETH on the wrong network?
Always match the network on your order page (Base mainnet for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
