Tunnel in 3 steps
-
Choose how much USDC to send and paste the Solana address that should receive funds on Solana mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, SOL 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 SOL? 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.
Solana — high-speed layer-1
SOL is the native token of Solana — built for fast, low-cost transfers and a large ecosystem of on-chain apps.
SOL not showing in my wallet?
Refresh or resync your Solana wallet. If the order shows a sent tx, verify the address matches exactly.
How fast is the SOL payout?
Solana settlements are typically very quick once your deposit confirms.
- Most SOL payouts land within minutes — often faster than Bitcoin or Ethereum routes.
- Check the order page for a payout signature before contacting support.
- Keep a small SOL balance in your wallet for future transaction fees.

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