Tunnel in 3 steps
-
Choose how much TON to send and paste the USD Coin 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 TON to that destination. Once confirmations clear, USDC is pushed to your payout wallet.
Before you broadcast
- TON confirmations are typically very fast — often under a minute.
- Use a TON mainnet wallet address (UQ… or EQ… format). Do not send jettons unless your order specifies a token.
- Send native TON on The Open Network only — not wrapped TON on other chains.
- Still waiting on USDC? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Toncoin — Telegram-native layer-1
TON powers The Open Network — fast transfers, low fees, and deep integration with Telegram wallets and mini-apps.
Sending TON on mainnet
Send native TON from a TON-compatible wallet. Jetton deposits require the exact asset your order lists.
Leave enough TON in your wallet to cover network fees on top of the swap amount.
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 not credited?
Verify your wallet is on Ethereum mainnet and the token contract matches official USDC on Ethereum.
When will USDC arrive?
ERC-20 USDC payouts follow Ethereum block times — usually minutes after your deposit confirms.
- Confirm your wallet is set to Ethereum mainnet, not Polygon, Base, or another L2.
- Add the official USDC token contract in your wallet if the balance does not appear automatically.
- Check the payout tx hash on Etherscan if your wallet shows no incoming transfer.
Why traders swap into USDC
USDC is widely used in DeFi and on exchanges that prefer a regulated dollar stablecoin.
On Ethereum mainnet it pairs naturally with ETH gas and most ERC-20 trading pairs.

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