Tunnel in 3 steps
-
Choose how much ETH to send and paste the Arbitrum address that should receive funds on Arbitrum One.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, ARB is pushed to your payout wallet.
Before you broadcast
- Ethereum deposits confirm quickly — usually within a few blocks (~12s each).
- During gas spikes, confirmation cost rises but inclusion remains fast.
- Send ETH on Ethereum mainnet only — not BSC, Base, or other L2s unless your order says otherwise.
- Still waiting on ARB? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
Sending ETH to the right network
Use an Ethereum mainnet wallet for deposits. L2 or alternate-chain sends may not be credited.
Leave enough ETH in your wallet to cover gas on top of the swap amount.
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 for ARB on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Ethereum → Arbitrum swaps.
How fast is a ETH → ARB swap?
Most routes settle within minutes. Final timing follows Ethereum mainnet deposit confirmations and Arbitrum One payout speed.
Does TunnelSwap hold my ETH or ARB?
No. You fund the deposit from your wallet and ARB is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for ETH?
Only send on the network shown for the order (Ethereum mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
