Tunnel in 3 steps
-
Choose how much USDC 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 USDC to that destination. Once confirmations clear, ZEC is pushed to your payout wallet.
Before you broadcast
- ERC-20 USDC follows Ethereum confirmation times.
- Send USDC on Ethereum mainnet only for this route — not Polygon, Base, or Solana USDC.
- Leave ETH in your wallet for gas when sending USDC.
- 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.
USD Coin — regulated dollar stablecoin
USDC on Ethereum mainnet is a widely trusted stablecoin for DeFi and transfers — always use ERC-20 on Ethereum unless stated otherwise.
USDC on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. L2 USDC is a different asset on-chain.
Gas fees apply to token transfers — ensure sufficient ETH balance.
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 USDC 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 USD Coin → Zcash swaps.
How fast is a USDC → ZEC swap?
Most routes settle within minutes. Final timing follows ERC-20 on Ethereum deposit confirmations and Zcash mainnet payout speed.
Does TunnelSwap hold my USDC 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 USDC?
Only send on the network shown for the order (ERC-20 on Ethereum). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
