Tunnel in 3 steps
-
Choose how much ETC 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 ETC to that destination. Once confirmations clear, OP is pushed to your payout wallet.
Before you broadcast
- Deposits on Ethereum Classic mainnet follow that chain's confirmation times.
- Network congestion can occasionally delay inclusion — check status if stuck.
- Send only ETC on Ethereum Classic mainnet to the address on your order page.
- 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.
Ethereum Classic
Always match ETC on Ethereum Classic mainnet when you send or receive — wrong-network transfers may not be credited.
Before you send
Use a wallet that supports Ethereum Classic mainnet.
Verify the deposit network on your order page matches your wallet.
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 ETC 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 Ethereum Classic → Optimism swaps.
How fast is a ETC → OP swap?
Most routes settle within minutes. Final timing follows Ethereum Classic mainnet deposit confirmations and Optimism mainnet payout speed.
Does TunnelSwap hold my ETC 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 ETC?
Only send on the network shown for the order (Ethereum Classic mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
