Tunnel in 3 steps
-
Choose how much USDC to send and paste the Dai address that should receive funds on ERC-20 on Ethereum.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, DAI 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 DAI? 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.
Dai on Ethereum
Always match DAI on ERC-20 on Ethereum when you send or receive — wrong-network transfers may not be credited.
Receiving DAI
Your wallet must be on ERC-20 on Ethereum.
Allow a few minutes after the order shows sent before opening support.

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