Tunnel in 3 steps
-
Choose how much ZEC to send and paste the Optimism address that should receive funds on Optimism mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ZEC to that destination. Once confirmations clear, OP 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 OP? 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.
Optimism — Ethereum L2 with low fees
OP is the governance token of Optimism — an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.
OP not received?
Confirm your wallet is on Optimism mainnet and fully synced.
OP payout tips
- Payouts go to Optimism — verify your wallet RPC is set to Optimism, not Ethereum mainnet.
- Check Optimistic Etherscan with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.

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