Tunnel in 3 steps
-
Choose how much ETH to send and paste the Ethereum address that should receive funds on Ethereum 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
- 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.
- 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.
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.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
What if my ETH hasn't arrived?
Check the order page for a payout transaction hash first.
Confirm your wallet is on Ethereum mainnet and fully synced.
How fast is the ETH payout?
Most payouts land within minutes once your deposit confirms — Ethereum blocks are ~12 seconds apart.
Receiving ETH on the correct network
- Payouts go to Ethereum mainnet — not BSC, Base, Arbitrum, or other L2s unless your order explicitly lists them.
- Double-check the address you paste: one wrong character sends funds to an unreachable wallet.
- Self-custody wallets (MetaMask, Rabby, hardware devices) are recommended for long-term holding.
Float vs fixed rate on ETH payouts
The rate mode you pick at the top of the swap widget affects how your final ETH amount is calculated.
- Float rate follows the market until your deposit confirms — best when mempools are quiet.
- Fixed rate locks the quote for a short window — useful when ETH price is moving quickly.

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 (Base) → Ethereum swaps.
How fast is a ETH → ETH swap?
Most routes settle within minutes. Final timing follows Base mainnet deposit confirmations and Ethereum 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 (Base mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
