Tunnel in 3 steps
-
Choose how much AVAX to send and paste the Optimism address that should receive funds on Optimism mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast AVAX to that destination. Once confirmations clear, OP is pushed to your payout wallet.
Before you broadcast
- Avalanche C-Chain confirmations are typically very fast — often under a minute.
- Send AVAX on Avalanche C-Chain only — not X-Chain or P-Chain unless your order specifies them.
- Use a C-Chain compatible wallet and address (0x…). Leave enough AVAX for gas.
- 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.
Avalanche — fast smart-contract L1
AVAX is the native token of Avalanche C-Chain — quick finality, EVM compatibility, and deep cross-chain liquidity.
AVAX on Avalanche C-Chain
Use an Avalanche C-Chain wallet for deposits. X-Chain and P-Chain addresses are not interchangeable with C-Chain.
Leave enough AVAX in your wallet to cover gas on top of the swap amount.
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 not received?
Confirm your wallet is on Optimism mainnet and fully synced.
OP payout tips
- 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.

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