Swap USDT from Polygon to WETH on Arbitrum One
Swap USDT from Polygon to WETH on Arbitrum One. Tether USDT leaves Polygon. WETH is what can arrive on Arbitrum One. You take ether price exposure in a wrapper that still needs a separate ETH balance.
The source is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. The destination is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Native ETH is the gas label, and this page does not buy it. Polygonscan for Tether, Arbiscan for WETH, chain id 42161, not Nova. Arbitrum One uses ETH for gas even when the token you hold is WETH.
Empty ETH line, frozen wrapper
Not Ethereum WETH
Tether stays on Polygon as a debit only
Nova and ARB do not rescue you

Frequently asked questions
What is the best way to swap USDT from Polygon to WETH on Arbitrum One?
The source is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. The destination is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. XAUConnect compares live routes and lets your own wallet sign.
Can I unwrap without ETH?
No. 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 needs ETH gas on chain id 42161. This quote does not deliver that ETH. ETH is not WETH. Arbiscan can list WETH beside an empty ETH balance. Fund ETH first, and do not look on Nova or on Etherscan. WETH cannot pay the fee to unwrap itself.
Is Polygon USDT the contract 0xdAC17?
No. 0xdAC17F958D2ee523a2206206994597C13D831ec7 is Ethereum Tether. This route spends 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on chain id 137. Polygonscan is the debit. Approving the Ethereum contract does not move the Polygon balance. POL pays the source. Chain id 137 is not chain id 1. Stay on Polygon for this debit.
What if I needed native ETH for fees?
Leave this page. Native ETH uses 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. WETH will not pay the next transaction. Sign the native output if the funds you move have to fund chain id 42161. This is Arbitrum One, not Nova. WETH will not pay the next fee on that chain.
