Tunnel in 3 steps
-
Choose how much SOL 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 SOL to that destination. Once confirmations clear, OP is pushed to your payout wallet.
Before you broadcast
- Solana confirmations are fast — often under a minute for practical purposes.
- Network outages or congestion can occasionally delay inclusion — check status if stuck.
- Use a Solana mainnet address (base58). Do not send SPL tokens unless the order specifies a token mint.
- 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.
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.
Solana deposit tips
Send native SOL on Solana mainnet. Token deposits require the exact asset your order lists.
Keep a small SOL balance for rent-exempt account requirements in some wallets.
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 SOL 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 Solana → Optimism swaps.
How fast is a SOL → OP swap?
Most routes settle within minutes. Final timing follows Solana mainnet deposit confirmations and Optimism mainnet payout speed.
Does TunnelSwap hold my SOL 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 SOL?
Only send on the network shown for the order (Solana mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
