Tunnel in 3 steps
-
Choose how much USDC to send and paste the Ethereum Classic address that should receive funds on Ethereum Classic mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, ETC is pushed to your payout wallet.
Before you broadcast
- ERC-20 USDC follows Ethereum confirmation times.
- Send USDC on Ethereum mainnet only for this route — not Polygon, Base, or Solana USDC.
- Leave ETH in your wallet for gas when sending USDC.
- Still waiting on ETC? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
USD Coin — regulated dollar stablecoin
USDC on Ethereum mainnet is a widely trusted stablecoin for DeFi and transfers — always use ERC-20 on Ethereum unless stated otherwise.
USDC on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. L2 USDC is a different asset on-chain.
Gas fees apply to token transfers — ensure sufficient ETH balance.
Ethereum Classic
Always match ETC on Ethereum Classic mainnet when you send or receive — wrong-network transfers may not be credited.
Receiving ETC
Your wallet must be on Ethereum Classic mainnet.
Allow a few minutes after the order shows sent before opening support.

Frequently asked questions
Do I need KYC to swap USDC for ETC on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for USD Coin → Ethereum Classic swaps.
How fast is a USDC → ETC swap?
Most routes settle within minutes. Final timing follows ERC-20 on Ethereum deposit confirmations and Ethereum Classic mainnet payout speed.
Does TunnelSwap hold my USDC or ETC?
No. You fund the deposit from your wallet and ETC is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for USDC?
Only send on the network shown for the order (ERC-20 on Ethereum). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
