Tunnel in 3 steps
-
Choose how much OP to send and paste the Avalanche address that should receive funds on Avalanche C-Chain.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast OP to that destination. Once confirmations clear, AVAX is pushed to your payout wallet.
Before you broadcast
- Optimism confirmations are usually fast — often within a minute.
- Send OP on Optimism mainnet only — not Ethereum, Base, or Arbitrum unless your order says otherwise.
- Use an Optimism-compatible wallet and address (0x…). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
- Still waiting on AVAX? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Optimism — Ethereum L2 with low fees
OP is the governance token of Optimism — an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.
OP on Optimism mainnet
Use an Optimism wallet for deposits. L1 Ethereum or other L2 sends may not be credited.
Leave enough ETH on Optimism for gas when moving OP or other tokens.
Avalanche — fast smart-contract L1
AVAX is the native token of Avalanche C-Chain — quick finality, EVM compatibility, and deep cross-chain liquidity.
AVAX not received?
Confirm your wallet is set to Avalanche C-Chain and fully synced.
AVAX payout tips
- Payouts go to Avalanche C-Chain — use a 0x-style address compatible with your wallet.
- Check Snowtrace or a similar explorer with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.

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