Tunnel in 3 steps
-
Choose how much ETC to send and paste the Arbitrum address that should receive funds on Arbitrum One.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETC to that destination. Once confirmations clear, ARB 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 ARB? 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.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB not received?
Confirm your wallet is on Arbitrum One and fully synced.
ARB payout tips
- Payouts go to Arbitrum One — use a 0x-style address on the correct chain.
- Check Arbiscan with the payout tx hash if your balance has not updated.
- Do not expect ARB on Ethereum mainnet unless your order explicitly lists it.

Frequently asked questions
Do I need KYC to swap ETC for ARB on TunnelSwap?

How fast is a ETC → ARB swap?
Most routes settle within minutes. Final timing follows Ethereum Classic mainnet deposit confirmations and Arbitrum One payout speed.

No. You fund the deposit from your wallet and ARB 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.
