Tunnel in 3 steps
-
Choose how much USDC to send and paste the Polygon address that should receive funds on Polygon mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, MATIC 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 MATIC? 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.
Polygon — low-cost EVM layer-2
MATIC (POL) powers Polygon — fast EVM transfers, low fees, and wide DeFi and bridge liquidity.
MATIC not received?
Confirm your wallet is on Polygon PoS mainnet and fully synced.
MATIC payout tips
- Use a Polygon-compatible wallet and verify the receive address starts with 0x.
- Check Polygonscan with the payout tx hash if your balance has not updated.
- Do not expect MATIC on Ethereum — this route pays out on Polygon PoS.

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