Tunnel in 3 steps
-
Choose how much ARB to send and paste the BNB address that should receive funds on BNB Smart Chain.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ARB to that destination. Once confirmations clear, BNB 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 BNB? 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.
BNB — native gas on BSC
BNB powers BNB Smart Chain — fast EVM transfers and the gas token for BEP-20 tokens on BSC.
BNB not received?
Confirm your wallet is on BNB Smart Chain mainnet and fully synced.
BNB payout tips
- Use a BSC-compatible wallet and verify the receive address starts with 0x.
- Do not expect BNB on Ethereum or BEP2 — this route pays out on BNB Smart Chain.
- Check BscScan with the payout tx hash if your wallet balance has not updated.

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