Tunnel in 3 steps
-
Set the BTC amount and paste your Zcash receive address — transparent (t-) or shielded (z-) as your wallet requires.
-
Create the order to lock the quote and see the BTC deposit address.
-
Send BTC on Bitcoin mainnet. After confirmation, ZEC is paid to your wallet.
Before you broadcast
- One Bitcoin confirmation is usually enough before the ZEC payout leg starts.
- SegWit BTC sends confirm faster and cost less — confirm your wallet can send to bc1… deposit addresses.
- Transparent and shielded ZEC addresses are not interchangeable — use the address type your order and wallet expect.
- Shielded ZEC payouts may take longer to display depending on wallet support — rescan if needed.
Bitcoin — the original digital asset
Since 2009, Bitcoin has been the benchmark cryptocurrency — deep liquidity, wide recognition, and the default on-ramp for cross-chain swaps.
Before you send BTC
- Confirm your wallet can send to SegWit (bc1…) addresses.
- Leave enough for a network fee — low fees mean slower confirmation.
- Send only BTC on Bitcoin mainnet to the address on your order page.
How long until Bitcoin confirms?
Block times vary with network load and your chosen fee.
- Use mempool.space or similar tools to check whether your fee is competitive.
- Explorers show queue position — compare against pending transaction volume.
- Average block interval is ~10 minutes, but longer gaps happen.
Why traders move BTC to other chains
Bitcoin offers deep liquidity and wide recognition — many swaps start with BTC as the funding asset.
Moving into Ethereum, stablecoins, or alt L1s lets you access DeFi, payments, or portfolio diversification without a custodial account.
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 BTC 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 Bitcoin → Zcash swaps.
How fast is a BTC → ZEC swap?
Most routes settle within minutes. Final timing follows Bitcoin mainnet deposit confirmations and Zcash mainnet payout speed.
Does TunnelSwap hold my BTC 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 BTC?
Only send on the network shown for the order (Bitcoin mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
