Tunnel in 3 steps
-
Choose how much ETH to send and paste the Dai address that should receive funds on ERC-20 on Ethereum.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, DAI 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 DAI? 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.
Dai on Ethereum
Always match DAI on ERC-20 on Ethereum when you send or receive — wrong-network transfers may not be credited.
Receiving DAI
Your wallet must be on ERC-20 on Ethereum.
Allow a few minutes after the order shows sent before opening support.

Frequently asked questions
Do I need KYC to swap ETH for DAI 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) → Dai swaps.
How fast is a ETH → DAI swap?
Most routes settle within minutes. Final timing follows Base mainnet deposit confirmations and ERC-20 on Ethereum payout speed.
Does TunnelSwap hold my ETH or DAI?
No. You fund the deposit from your wallet and DAI 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.
