Tunnel in 3 steps
-
Choose how much ADA 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 ADA to that destination. Once confirmations clear, OP is pushed to your payout wallet.
Before you broadcast
- Cardano deposits need several confirmations before the swap proceeds.
- Block times are around 20 seconds but can vary with network load.
- Use a Shelley-era Cardano address — legacy Byron formats may not be supported on all 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.
Cardano — research-driven layer-1
ADA is the native token of Cardano — a proof-of-stake network focused on security and formal verification.
Sending ADA
Send native ADA on Cardano mainnet from a compatible wallet.
Leave enough ADA for the transaction fee in addition to your 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 ADA 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 Cardano → Optimism swaps.
How fast is a ADA → OP swap?
Most routes settle within minutes. Final timing follows Cardano mainnet deposit confirmations and Optimism mainnet payout speed.
Does TunnelSwap hold my ADA 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 ADA?
Only send on the network shown for the order (Cardano mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
