Tunnel in 3 steps
-
Choose how much ETH to send and paste the Ethereum (Base) address that should receive funds on Base mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, ETH 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 ETH? 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.
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.
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.

Frequently asked questions
Do I need KYC to swap ETH for ETH 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 → Ethereum (Base) swaps.
How fast is a ETH → ETH swap?
Most routes settle within minutes. Final timing follows Ethereum mainnet deposit confirmations and Base mainnet payout speed.
Does TunnelSwap hold my ETH or ETH?
No. You fund the deposit from your wallet and ETH 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.
