Tunnel in 3 steps
-
Choose how much ARB to send and paste the Dai address that should receive funds on ERC-20 on Ethereum.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ARB to that destination. Once confirmations clear, DAI is pushed to your payout wallet.
Before you broadcast
- Arbitrum confirmations are usually fast — often within a minute.
- Send ARB on Arbitrum One only — not Ethereum, Optimism, or Base unless your order says otherwise.
- Use an Arbitrum-compatible wallet and address (0x…). Leave enough ETH on Arbitrum for gas if needed.
- Still waiting on DAI? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB on Arbitrum One
Use an Arbitrum One wallet for deposits. Other chains use different assets even with the same ticker.
Leave enough ETH on Arbitrum for gas on top of the swap amount when required.
Dai on Ethereum
Always match DAI on ERC-20 on Ethereum when you send or receive — wrong-network transfers may not be credited.
Receiving DAI
Your wallet must be on ERC-20 on Ethereum.
Allow a few minutes after the order shows sent before opening support.
Before you swap
Avoid wrong-network deposits and address format mistakes — read these guides first.

Frequently asked questions
Do I need KYC to swap ARB for DAI on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Arbitrum → Dai swaps.
How fast is a ARB → DAI swap?
Most routes settle within minutes. Final timing follows Arbitrum One deposit confirmations and ERC-20 on Ethereum payout speed.
Does TunnelSwap hold my ARB or DAI?
No. You fund the deposit from your wallet and DAI is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for ARB?
Only send on the network shown for the order (Arbitrum One). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
