Tunnel in 3 steps
-
Choose how much USDC to send and paste the BNB address that should receive funds on BNB Smart Chain.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, BNB 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 BNB? 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.
BNB — native gas on BSC
BNB powers BNB Smart Chain — fast EVM transfers and the gas token for BEP-20 tokens on BSC.
BNB not received?
Confirm your wallet is on BNB Smart Chain mainnet and fully synced.
BNB payout tips
- Use a BSC-compatible wallet and verify the receive address starts with 0x.
- Do not expect BNB on Ethereum or BEP2 — this route pays out on BNB Smart Chain.
- Check BscScan with the payout tx hash if your wallet balance has not updated.

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