Tunnel in 3 steps
-
Choose how much ADA to send and paste the Arbitrum address that should receive funds on Arbitrum One.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ADA to that destination. Once confirmations clear, ARB 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 ARB? 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.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB not received?
Confirm your wallet is on Arbitrum One and fully synced.
ARB payout tips
- Payouts go to Arbitrum One — use a 0x-style address on the correct chain.
- Check Arbiscan with the payout tx hash if your balance has not updated.
- Do not expect ARB on Ethereum mainnet unless your order explicitly lists it.

Frequently asked questions
Do I need KYC to swap ADA for ARB 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 → Arbitrum swaps.
How fast is a ADA → ARB swap?
Most routes settle within minutes. Final timing follows Cardano mainnet deposit confirmations and Arbitrum One payout speed.
Does TunnelSwap hold my ADA or ARB?
No. You fund the deposit from your wallet and ARB 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.
