Tunnel in 3 steps
-
Choose how much LTC 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 LTC to that destination. Once confirmations clear, OP is pushed to your payout wallet.
Before you broadcast
- Litecoin typically needs a few confirmations before the swap continues.
- Blocks target 2.5 minutes — still subject to mempool delays.
- Use a standard Litecoin mainnet address (Legacy, SegWit, or M-address formats supported on most routes).
- 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.
Litecoin — Bitcoin's first fork
Litecoin (LTC) is a 2011 Bitcoin fork created by Charlie Lee, with early input from other developers including a former Google engineer. It keeps peer-to-peer transfers but targets faster blocks and lower everyday fees. Traders often call it "digital silver."
The speed and fees of the Litecoin blockchain
When you fund a swap with LTC, ~2.5-minute blocks help deposits confirm sooner than on many busier chains.
Typical fees stay low — about 0.0004 LTC (~$0.02 at current prices). Leave a little extra for the miner fee so the full amount you intend to send reaches the deposit address.
Litecoin address formats
If a send fails, your wallet may be using an unsupported address type for this route.
Contact support with your order ID before retrying on a different format.
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 LTC 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 Litecoin → Optimism swaps.
How fast is a LTC → OP swap?
Most routes settle within minutes. Final timing follows Litecoin mainnet deposit confirmations and Optimism mainnet payout speed.
Does TunnelSwap hold my LTC 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 LTC?
Only send on the network shown for the order (Litecoin mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
