Three steps on Web3Swap
-
Enter the ARB size and paste the Ethereum (Base) payout address for Base mainnet on this Web3Swap ticket.
-
Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.
-
Broadcast exactly that ARB amount to the deposit. After Arbitrum One confirms, ETH is paid to your wallet.
Before you broadcast
- Arbitrum confirmations are usually fast — often within a minute.
- Send ARB on Arbitrum One only — not Ethereum, Optimism, or Base unless your order says otherwise.
- Use an Arbitrum-compatible wallet and address (0x…). Leave enough ETH on Arbitrum for gas if needed.
- If ETH is late, refresh your wallet and re-check the ticket. When a payout hash is already listed, email or SimpleX support with your Exchange ID — Web3Swap has no login that lists expired orders.
Arbitrum One tickets — stay on L2
ARB governs Arbitrum One. Web3Swap Arbitrum tickets expect an L2 wallet — mainnet ETH sent to this deposit typically cannot be recovered.
ARB on Arbitrum One
Use an Arbitrum One wallet for deposits. Other chains use different assets even with the same ticker.
Leave enough ETH on Arbitrum for gas on top of the swap amount when required.
Base ETH tickets — Coinbase L2 rail
Native ETH on Base is not Ethereum L1. Web3Swap Base tickets need a Base wallet — low fees, fast finality, still no hosted balance.
Base ETH not received?
Confirm your wallet is on Base mainnet and fully synced — not Ethereum L1.
Base ETH payout tips
- Payouts go to Base — verify your wallet network is Base (chain ID 8453).
- Check Basescan with the payout tx hash from your order page.
- Bridging to Ethereum L1 is a separate step after you receive ETH on Base.
Deposit checklist
Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

FAQ for this route
Do I need KYC or a Web3Swap login for ARB → ETH?
No. A standard Arbitrum → Ethereum (Base) ticket on Web3Swap skips signup and ID upload. You stay self-custodial on both legs.
How soon does ETH usually arrive?
After the Arbitrum One deposit is final, many payouts leave within minutes. Congestion on Arbitrum One or Base mainnet can stretch that — mempools and fees set the clock, not a compliance hold.
Does Web3Swap custody my ARB or ETH?
No. You broadcast ARB from a wallet you control; ETH pays only to the address you paste. Nothing sits as a named Web3Swap balance.
What if I send ARB on the wrong rail?
Match Arbitrum One exactly as printed on the Web3Swap ticket badge. A wrong-chain deposit often cannot be credited automatically — verify before you broadcast.
