Tunnel in 3 steps

  1. Choose how much USDC to send and paste the Optimism address that should receive funds on Optimism mainnet.

  2. Open the order to freeze the quote and reveal a one-time deposit destination.

  3. Broadcast USDC to that destination. Once confirmations clear, OP 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 OP? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.

  • Payouts go to Optimism — verify your wallet RPC is set to Optimism, not Ethereum mainnet.
  • Check Optimistic Etherscan with the payout tx hash from your order page.
  • Allow a minute for your wallet to refresh after the explorer shows the transfer.
