If speed matters, Relay settled in about 1 second in test quotes; if the amount matters most, compare USDT0 and L2Pass RFQ. **3. Set a refund address** For L2Pass RFQ and L2Pass Private, set the refund address to an Ethereum wallet you control. If the swap cannot complete, your deposit is returned there. **4. Pay by wallet or deposit address** On USDT0, Relay and LI.FI, sign the transaction in your Ethereum wallet. On L2Pass RFQ and L2Pass Private, send USDT to the one-time deposit address from your connected wallet, any wallet or an exchange. **5. Track the swap** For L2Pass RFQ and L2Pass Private, follow the status in **Recent swaps**. A USDT0 transfer is a LayerZero message, so you can follow it on [LayerZero Scan](https://layerzeroscan.com/) with your Ethereum transaction hash. ## Things to know * **Gas on Ethereum only.** You pay gas in ETH on Ethereum. The Arbitrum network fee is deducted from the amount shown, so you do not need ETH on Arbitrum to receive. * **USDT0 on Arbitrum.** The USDT that L2Pass Swap delivers on Arbitrum is USDT0. * **Refunds.** On-chain routes revert (gas is not refundable). Deposit-address routes return your deposit to the refund address; provider and network fees may be deducted. * **No partial fills.** A swap completes in full or does not execute. * **Compliance checks.** No account or KYC is needed for regular use, though a provider may request extra checks for a specific transaction. If a provider flags a swap as high risk under AML or sanctions rules, it decides whether to complete, refund or hold it, and a refund is not guaranteed. ## FAQ > **How long does it take to bridge USDT from Ethereum to Arbitrum?** > > From about 1 second on Relay to about 1.5 minutes on the native USDT0 bridge, in test quotes on October 19, 2026.
