Tunnel in 3 steps
-
Choose how much ZEC to send and paste the Kaspa address that should receive funds on Kaspa mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ZEC to that destination. Once confirmations clear, KAS is pushed to your payout wallet.
Before you broadcast
- Zcash confirmations follow mainnet block times — usually a few minutes.
- Transparent (t-) and shielded (z-) addresses are not interchangeable — use the type your order specifies.
- Shielded payouts may take longer to appear depending on wallet support.
- Still waiting on KAS? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Zcash — optional shielded privacy
ZEC supports transparent and shielded addresses — pick the receive format your wallet actually supports.
Transparent vs shielded ZEC
Sending to the wrong address type is a common failure mode.
If unsure, ask support which format your order uses before broadcasting.
Kaspa
Always match KAS on Kaspa mainnet when you send or receive — wrong-network transfers may not be credited.
Receiving KAS
Your wallet must be on Kaspa mainnet.
Allow a few minutes after the order shows sent before opening support.
Before you swap
Avoid wrong-network deposits and address format mistakes — read these guides first.

Frequently asked questions
Do I need KYC to swap ZEC for KAS on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Zcash → Kaspa swaps.
How fast is a ZEC → KAS swap?
Most routes settle within minutes. Final timing follows Zcash mainnet deposit confirmations and Kaspa mainnet payout speed.
Does TunnelSwap hold my ZEC or KAS?
No. You fund the deposit from your wallet and KAS is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for ZEC?
Only send on the network shown for the order (Zcash mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
