Tunnel in 3 steps
-
Choose how much DAI 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 DAI to that destination. Once confirmations clear, ARB is pushed to your payout wallet.
Before you broadcast
- Deposits on ERC-20 on Ethereum follow that chain's confirmation times.
- Send only on ERC-20 on Ethereum — other networks are not interchangeable.
- Double-check the network on your order page before you send.
- 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.
Dai on Ethereum
Always match DAI on ERC-20 on Ethereum when you send or receive — wrong-network transfers may not be credited.
Before you send
Use a wallet that supports ERC-20 on Ethereum.
Verify the deposit network on your order page matches your wallet.
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 DAI 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 Dai → Arbitrum swaps.
How fast is a DAI → ARB swap?
Most routes settle within minutes. Final timing follows ERC-20 on Ethereum deposit confirmations and Arbitrum One payout speed.
Does TunnelSwap hold my DAI 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 DAI?
Only send on the network shown for the order (ERC-20 on Ethereum). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
