How to bridge USDT from Tron to Arbitrum

1

Open L2Pass Swap

Go to swap.l2pass.com, choose USDT on Tron as the source and USDT on Arbitrum as the destination, then enter the amount and set the Arbitrum address that will receive the USDT.
2

Compare the routes

Each route card shows the expected output, minimum received, estimated time and fees. Default slippage is 0.05% (editable) and does not apply to fixed-output routes such as USDT0.
3

Set a refund address

For L2Pass RFQ and L2Pass Private, set the refund address to a Tron wallet you control. If the swap cannot complete, your deposit is returned there.
4

Pay by wallet or deposit address

On the USDT0 route, sign the transaction in your Tron wallet. On L2Pass RFQ and L2Pass Private, send USDT to the one-time deposit address from your connected wallet, any Tron wallet or an exchange, by address or QR code. If you send from an exchange, check that the amount that arrives matches the quote, since some exchanges deduct their withdrawal fee from it.
5

Track the swap

For L2Pass RFQ and L2Pass Private, follow the status in Recent swaps: Awaiting deposit, Deposit confirmed, then Complete. A USDT0 transfer is a LayerZero message, so you can follow it on LayerZero Scan with your Tron transaction hash.

Things to know

  • Gas on Tron only. Sending TRC-20 USDT costs TRX for energy and bandwidth. Any network fee on the destination chain is deducted from the amount shown, so you do not need gas there.
  • 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.
  • Minimum amount. Some routes have a minimum swap amount that varies by pair. If your amount is below it, the route is listed as unavailable with the minimum shown.
  • 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.
