Tunnel in 3 steps
-
Choose how much XLM 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 XLM to that destination. Once confirmations clear, OP is pushed to your payout wallet.
Before you broadcast
- Stellar confirmations are typically very fast — often within seconds.
- A minimum XLM balance may be required to activate or maintain your Stellar account.
- Use a Stellar mainnet address (starts with G…). Include a memo if your receive wallet or exchange requires one.
- 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.
Stellar — fast payments network
XLM (Stellar Lumens) powers the Stellar network — built for low-cost cross-border transfers and tokenized assets.
Sending XLM on Stellar
Send native XLM on Stellar mainnet from a compatible wallet.
If your payout destination requires a memo, enter it exactly on your order form — missing memos are a common support issue.
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 XLM 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 Stellar → Optimism swaps.
How fast is a XLM → OP swap?
Most routes settle within minutes. Final timing follows Stellar mainnet deposit confirmations and Optimism mainnet payout speed.
Does TunnelSwap hold my XLM 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 XLM?
Only send on the network shown for the order (Stellar mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
