Tunnel in 3 steps
-
Choose how much ARB to send and paste the Tether 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, USDT 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 USDT? 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.
Tether — dollar-pegged stablecoin
USDT on Ethereum (ERC-20) is widely used in DeFi — send only on Ethereum mainnet.
Receiving ERC-20 USDT
Your wallet must be on Ethereum mainnet with the USDT token visible.

Frequently asked questions
Do I need KYC to swap ARB for USDT 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 → Tether swaps.
How fast is a ARB → USDT 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 USDT?
No. You fund the deposit from your wallet and USDT 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.
