Tunnel in 3 steps
-
Choose how much ARB 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 ARB to that destination. Once confirmations clear, ZEC is pushed to your payout wallet.
Before you broadcast
- Arbitrum confirmations are usually fast — often within a minute.
- Send ARB on Arbitrum One only — not Ethereum, Optimism, or Base unless your order says otherwise.
- Use an Arbitrum-compatible wallet and address (0x…). Leave enough ETH on Arbitrum for gas if needed.
- 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.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB on Arbitrum One
Use an Arbitrum One wallet for deposits. Other chains use different assets even with the same ticker.
Leave enough ETH on Arbitrum for gas on top of the swap amount when required.
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 ARB 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 Arbitrum → Zcash swaps.
How fast is a ARB → ZEC swap?
Most routes settle within minutes. Final timing follows Arbitrum One deposit confirmations and Zcash mainnet payout speed.
Does TunnelSwap hold my ARB 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 ARB?
Only send on the network shown for the order (Arbitrum One). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
