Tunnel in 3 steps
-
Choose how much USDC to send and paste the Ethereum address that should receive funds on Ethereum mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, ETH 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 ETH? 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 — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
What if my ETH hasn't arrived?
Check the order page for a payout transaction hash first.
Confirm your wallet is on Ethereum mainnet and fully synced.
How fast is the ETH payout?
Most payouts land within minutes once your deposit confirms — Ethereum blocks are ~12 seconds apart.
Receiving ETH on the correct network
- Payouts go to Ethereum mainnet — not BSC, Base, Arbitrum, or other L2s unless your order explicitly lists them.
- Double-check the address you paste: one wrong character sends funds to an unreachable wallet.
- Self-custody wallets (MetaMask, Rabby, hardware devices) are recommended for long-term holding.
Float vs fixed rate on ETH payouts
The rate mode you pick at the top of the swap widget affects how your final ETH amount is calculated.
- Float rate follows the market until your deposit confirms — best when mempools are quiet.
- Fixed rate locks the quote for a short window — useful when ETH price is moving quickly.

Frequently asked questions
Do I need KYC to swap USDC for ETH 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 swaps.
How fast is a USDC → ETH swap?
Most routes settle within minutes. Final timing follows ERC-20 on Ethereum deposit confirmations and Ethereum mainnet payout speed.
Does TunnelSwap hold my USDC or ETH?
No. You fund the deposit from your wallet and ETH 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.
