Tunnel in 3 steps
-
Choose how much ETH to send and paste the Zcash address that should receive funds on Zcash mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, ZEC 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 ZEC? 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.
Zcash — optional shielded privacy
ZEC supports transparent and shielded addresses — pick the receive format your wallet actually supports.
ZEC receipt troubleshooting
Confirm address type matches your wallet. Rescan the blockchain in your Zcash client if needed.
Transparent vs shielded payouts
Zcash supports both transparent (t-) and shielded (z-) addresses — they are not interchangeable.
- Use the address type your wallet actually supports before placing the order.
- Shielded payouts may take longer to appear depending on wallet software.
- If the order shows a sent tx but balance is zero, rescan the chain in your Zcash client first.

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