Tunnel in 3 steps
-
Choose how much USDC to send and paste the Arbitrum address that should receive funds on Arbitrum One.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDC to that destination. Once confirmations clear, ARB 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 ARB? 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.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB not received?
Confirm your wallet is on Arbitrum One and fully synced.
ARB payout tips
- Payouts go to Arbitrum One — use a 0x-style address on the correct chain.
- Check Arbiscan with the payout tx hash if your balance has not updated.
- Do not expect ARB on Ethereum mainnet unless your order explicitly lists it.

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