Tunnel in 3 steps
-
Choose how much ETH to send and paste the Cardano address that should receive funds on Cardano mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, ADA is pushed to your payout wallet.
Before you broadcast
- Ethereum deposits confirm quickly — usually within a few blocks (~12s each).
- During gas spikes, confirmation cost rises but inclusion remains fast.
- Send ETH on Ethereum mainnet only — not BSC, Base, or other L2s unless your order says otherwise.
- Still waiting on ADA? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
Sending ETH to the right network
Use an Ethereum mainnet wallet for deposits. L2 or alternate-chain sends may not be credited.
Leave enough ETH in your wallet to cover gas on top of the swap amount.
Cardano — research-driven layer-1
ADA is the native token of Cardano — a proof-of-stake network focused on security and formal verification.
ADA payout delays
Resync your Cardano wallet if the order shows a sent transaction but balance is unchanged.
When will ADA arrive?
Cardano block times are around 20 seconds — payouts typically follow within several blocks.
- Use a Shelley-era Cardano address compatible with your wallet.
- Check a Cardano explorer with the payout tx hash from your order page.
- Allow a few extra minutes if your wallet is still syncing the latest epoch.

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